6.0 Installation & Setup

6.0 Installation & Setup

6.1 Inspecting Shipment

This machine has been carefully packed to prevent damage during shipment. However, claims for damage or loss are the responsibility of the recipient. Inspect all shipments as soon as they are received. If there is any noticeable damage, note it on the freight bill. Visual and/or hidden damage must be reported to the claims department of the carrier within 15 days. Contact your dealer if you need any assistance. Check the contents of the box against the packing list on page 8. Make sure there are no missing items.

6.2 Uncrating

This machine is lagged to a wood skid and covered with a triple-walled corrugated container. Loosen the flaps of the carton where they are attached to the skid. When loose, the carton can be lifted straight up. Remove the side tables and accessory box, which are also attached to the skid. Place the cutter/skid about where the machine will be positioned and remove the lag screws from the skid.

Remove the lower shipping block holding the counter weight up. It is secured in place with a lag screw and washers. Remove the upper shipping block, which is also secured in place with a lag screw and washers. If the upper wood block cannot be removed because the knife bar is in the way, wait until the machine is powered up for the first time and remove the upper wood block when the knife bar has been raised under power.

Make sure that both of the rollers, for the counter weight, are riding on the guide shaft. It is possible that during shipping, one may have moved off of the shaft. The rollers are located on the top and bottom of the counter weight. The counter weight is located inside the left front enclosure door behind the clamp cylinder. Make sure if the machine is ever reshipped the counter weight is blocked up so that there is slack in the counter weight chain and the counter weight does not bounce. The counter weight should be blocked/ held up with a wood 2x4 piece of lumber 11-5/8” long. This block needs to be secured in place with a lag screw and washers as shown in figure 2, page 12.

Remove the shipping block securing the paper deflector. This shipping block is wedged between the bottom of the paper deflector assembly and the mounting pin for the paper deflector extension spring. The shipping block is held in place by a cable tie. The cable tie and shipping block are accessible through the left arch access hole by removing the left arch end cover (Figure 3), page 12. If the machine is ever reshipped, a 1” X 2” piece of lumber (actual size 3/4” X 1-1/2”) 17” long should be wedged in between the paper deflector assembly and the mounting pin for the paper deflector extension spring as it was when shipped from the factory.

Before the machine can be run for the first time, the 3/4 NPT plug in the reservoir needs to be replaced with the breather cap, see section 6.8 Hydraulic Check on page 17.

Save the packing materials.

6.0 Installation & Setup

6.3 Re-Crating and Shipping

Save the packing materials and braces. All packing blocks and hardware should be saved or reproduced in order to ship the machine again. If the machine is not repacked as it came from the factory, damage will result when trucked.

• Remove the knife before shipping.
• Brace the back-end of the table to the skid using a 2x4.
• Use a skid larger than the outer tip-to-tip dimensions of the machine.
• Block the counter-weight according to page 12, Figure 2 and 3
• Remove the hydraulic breather cap and plug with a ¾ NPT plug.
• Always lift and transport from the front of the machine. The carton has lifting instructions, so it must be placed properly on the skid.

Challenge is not responsible for an improperly packed machine. The skid and packing materials are available for purchase from Challenge.

6.4 Lifting Instructions

Professional riggers should do unpacking, handling, and positioning. If handling or unpacking is a problem, your dealer or a local trucking facility should be able to supply or recommend a qualified rigger. This 3750-lb/1701-kg machine should be moved with experienced people and the proper equipment. Do not risk personal injury or damage by attempting to move machinery with makeshift equipment or inadequate manpower.

Lifting straps may also be used to lift the machine by placing the straps around the front and rear of the table. When straps are used in this way, wood blocks must be placed beside the lead screw to prevent damage, (Figure 4). A bent lead screw will cause the backgauge to bind. The lead screw cover must also be removed. Do not strap around the lead screw cover.

The backgauge should be positioned all the way to the front of the table and straps placed as close the machine body as possible. Gently lift the cutter, remove the skid and carefully place the cutter on the floor.

6.5 Cleaning

Wipe down the table and bare metal surfaces with a non-flammable solvent such as CRC or blanket wash. The table surface is cast iron and will rust if left unprotected. Coat the table with a nonabrasive wax. A Cutter Care Kit, p/n 16077, with cleaner and wax, is available thru your Authorized Challenge Dealer. The protective film on the console may be removed. Never clean console with petroleum based solvents. Damage will result. See also Cleaning under Maintenance Guide on page 37.

6.0 Installation & Setup

6.6 Assembly: Standard

Unless otherwise specified, the only items that have been disassembled for shipping are the extension side tables. To assemble the table extensions, follow the procedure below.

NOTE: Assembled side tables are awkward and heavy. Use two people to attach the side tables.

1. Install the side table supports. Each support is attached to the frame with two (2) bolts and washers. (Mounting bolts are shipped installed in the frame - remove them to install supports.)
2. Thread the 1/2-13 hex nut, packed with the machine, onto the 1/2-13 X 2-1/4 hex bolt. Screw the bolt into the nut welded on the table support.
3. Assemble the side table backs to the table surfaces. The extension table bolts and hex nuts are packed inside the tool kit box. Tables are installed with the clearance hole for the knife gib adjusting screws towards the middle of the cutter. Make sure the right hand side table back plate is bolted onto the right hand side table, and the left hand side table back plate is bolted onto the left hand side table.
4. Have one person hold the assembled side table in position while the other aligns the holes and threads the mounting bolts with washers. (Mounting bolts are shipped installed in the side of table- remove them to install tables.)
5. Use a 9/16” socket and extension to lightly tighten the mounting bolts, then tap the extension table up or down with a rubber mallet until it is flush with the main table. Run a straight edge or sheet of paper over the seam to check the fit. Make sure your stock will not catch on the seam.
6. Locate the leveling bolt that was threaded into the welded nut on the table support in step 2. You may have to loosen the mounting bolts a little to allow enough play to level the table. When the extension tables are leveled and the surface joints even, tighten the mounting bolts securely. Make sure the 1/2-13 hex nut, threaded on the leveling bolt in step 2, is tightened to prevent the leveling bolt from loosening.
7. The tables are powder coated and need only be wiped down with a dry cloth. DO NOT apply solvents or abrasive cleaners to extension table surfaces. They may cause discoloration or scratches.

6.7 Assembly: Table Out

If your cutter has been shipped knocked-down, it is even more important to have a rigger or qualified personnel with the right equipment to position and assemble your cutter.

Your cutter will arrive in two crates. One contains the arch/base assembly. The second, accessory box contains the parts, accessories, and table. Reassemble as follows:

1. Remove the crate from the arch/base assembly.
2. Remove the accessories from the accessory box.
3. Lift the table out of the accessory box. NOTE: Be careful not to damage or bend the lead screw or backgauge drive motor assembly. Use wood blocks beside the screw if straps are used (Figure 4 on page 13).

6.0 Installation & Setup

4. Remove the rear arch cover assembly.
5. Insert the table from the rear of the machine, through the arch. The table is located using two special taper pins through holes on the rear table mounting pads.
6. After locating the table, install the eight (8) table bolts. Seat the taper pins and tighten the bolts.
7. Attach the front and rear side guides. Install the table end cover. Install the rear table polycarbonate cover to the table end cover and side guides.
8. Install the paper deflector through the access point inside the front enclosure, under the table. Depress the deflector with your thumb while installing the assembly to clear the knife bar, (Figure 5). Attach with two 3/8-16 x 1" socket head cap screws.

One socket screw must be installed from inside the arch. Remove the side guard plate for access. Both bolts should have shake proof lock washers.

9. Mount the cut button cable assembly to the underside of the table.
10. Mount the main power disconnect switch to the underside of the table.
11. Fasten one end of the encoder cable, chain carrier to the frame of the machine. Route the carrier chain through the cutout in the table brace. Fasten it to the backgauge carrier. Install a strain relief cable tie to the backgauge carrier to secure the encoder cable. Plug the encoder cable into the encoder. (Figure 6, page 16)

6.0 Installation & Setup

12. Install the forward and rearward lead screw covers using eight 1/4-20 x ½” button head cap screws, eight ¼” flat washers, and eight ¼” internal tooth lock washers.
13. Reconnect the backgauge motor cable. From the table, the cable runs through the strain relief bushing into the motor housing, (figure 8, page 17). Attach the wires according to the wiring schematic in the back of this manual for the machine model you have. Cable

6.0 Installation & Setup

14. Connect the tube from the blower to the plastic connector attached to the air channel cover on the bottom of the table if required. Reconnect the wires to the air blower and solenoid according to the wiring diagram for the machine model you have.
15. Open each electric eye end-cover. Mount the electric eyes to the machine as shown in Figure 9. The end-covers are oriented toward the outside of the machine. Connect each electric eye, leaving the connectors inside the electric eye cases. Replace the end-covers.

6.8 Hydraulic Check

When the machine is shipped, the breather cap should be replaced with a 3/4 NPT plug. This is how the machine is shipped from the factory. Before the machine can be run for the first time the NPT plug needs to be replaced with the breather cap. Access the plug behind the small cover on the hydraulic power unit cover behind the machine.

6.0 Installation & Setup

The hydraulic reservoir is filled with 15 gallons of grade #46 hydraulic oil at the factory. The fluid level should be checked before operation, and periodically during normal operation. The reservoir is located behind the cutter, beneath the table (). The hydraulic tank has a breather cap that can be removed for changing the oil and checking the oil level. The reservoir should be kept full at all times. Fill the reservoir so that the oil level is 3/4” below the top of the inside of the hydraulic tank.

NOTE: DO NOT OVERFILL. Overfilling may cause leakage when the machine is hot.

6.9 Power Hook-Up

SHOCK HAZARD! Always disconnect power at main power panel before working on the cutter. Lock it out to prevent accidental power up. See Power Lockout Procedure (page 5).

For satisfactory operation, be sure that your cutter is wired for the correct phase and voltage and has adequate power. The correct electrical specifications for your machine are shown on the serial plate. Check the machine serial plate before connecting the power. For future reference, transfer this information to the front cover of this manual.

Watch Setup Voltage- Inadequate power to the cutter can be a major source of problems. Too many machines on the same circuit will reduce the power to each machine. Inadequate voltage will frequently cause overheating, loss of power, and in extreme cases, failure to operate. Test your voltage when the shop is at actual working levels. Challenge recommends a dedicated line with a lockable disconnect to provide adequate power for this machine.

Important: You must have an adequate size circuit and heavy enough wiring for this machine. The circuit size should be a minimum of 20% greater than the amperage rating on the machine nameplate. If a wire is run over 75 feet (23 meters), the next size wire should be used. Check local electrical codes.

Electrical Specifications for Champion 370 cutters:

6.0 Installation & Setup

6.10 Three Phase Hook-Up

The power source is connected to the cutter through the bottom of the power panel (right hand side). A main power control switch and power cord providing the machine with power is the responsibility of the customer and should be set in accordance with the local electrical code.

1. DISCONNECT AND LOCK OUT THE POWER (See Power Lockout procedure, page 5)
2. Thread the power cord through a conduit connector into the power panel.
3. Fasten the ground lead to the ground terminal lug (Figure 11).
4. Fasten the three power leads to the three terminals of the main power terminal block- L1, L2, & L3.
5. Close the electrical panel doors and latch them. Unlock the main panel and turn on the power. Turn on the main power disconnect switch located on the front face of the table.
6. Press both cut buttons simultaneously to activate the motor and check to make sure it is turning the same direction as the arrow on the motor casing.

If it isn’t, disconnect the power and exchange any two leads (L1, L2 or L3) of the power cord as in Figure 12, page 20. The motor will now turn the correct direction.

6.0 Installation & Setup

6.11 False Clamp Plate

ALWAYS disconnect the power and LOCK IT OUT before installing or removing the false clamp plate. NEVER attempt to install or remove the false clamp plate while the machine is running. Remove all tools and stand clear when reconnecting power.

To prevent marking on pressure sensitive jobs, a false clamp plate has been included (installed) with your machine. This plate attaches to the bottom of the clamp. It is secured from the front of the cutter with three set screws that clamp against the mounting rods on the false clamp plate.

1. DISCONNECT THE POWER AND LOCK IT OUT (See Power Lock-Out Procedure, page 5)
2. Position the false clamp plate under the clamp. The locator pegs should be positioned to the rear of the cutter and are set into holes in the bottom of the clamp.
3. With a 1/8" Allen wrench, back off the setscrews in front of the clamp and raise the plate up to the bottom of the clamp. It may be necessary to bring the clamp down slightly with the foot pedal in order to access the far left setscrew. Raise the false clamp plate evenly or it will have a tendency to bind. When the plate has been raised into position and is flush with the bottom of the clamp, tighten the setscrews to hold the plate in position.
4. Make sure that all tools have been taken off the cutter table, reconnect the power, and turn on the power.

NOTE: The cutter cannot make cuts smaller than 2-5/8" (66.7 mm) with the false clamp plate installed.

8.1 Routine Maintenance/Adjustments

CAUTION: ! KNIFE SAFETY ! Knives are DANGEROUS!!! They are heavy and very sharp, even after use. Keep the edge away from your body and keep the area clear of others when handling knives. Never touch the cutting edge! To prevent personal injury and damage to the knife, always keep knives in their holders with screws tightened. You are aware of the dangers, but others may not be. Never attempt to hone, polish, or service the knife in any way. Failure to follow safety procedures may result in severe lacerations or dismemberment.

Make sure the knife lifter is properly installed, see instructions following. Keep handling of unprotected knives to an absolute minimum. Clear off the cutter table before removing knife. Have a scabbard on the cutter table and insert the knife immediately. Warn people of any unprotected knife. Knife changing is a ONE PERSON OPERATION. Having more than one person changing knives increases hazard.

The knife changing equipment shown in Figure 16 is included in the cutter tool kit. The following instructions show how to remove and install a new or re-sharpened knife. Read through these instructions AT LEAST ONCE before attempting to actually change or install any blades.

1. Clear the cutter table. Place chipboard directly under the knife to prevent nicking if the blade hits the table.
2. Go to the MAINTENANCE screen and choose KNIFE ADJUST. Choose KNIFE DOWN, then press and hold the cut buttons to send the knife to the down position.
3. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
4. Back off the three (3) knife adjusting screws on the top of the knife bar, (Figure 15 on page 25), as far as they will go (counterclockwise). A new knife will cut deeper than a knife that has been ground several times. If the adjusting screws are not backed off, damage will result to the new knife, paper deflector and/or the cutting stick.
5. Remove the right-most knife bolt. This bolt will not be accessible after the knife bar is raised.
6. Unlock and reconnect the power then raise the knife bar.
7. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
8. Remove the bolts in the two slotted holes of the knife bar and replace them with the knife lifter assembly. Tighten the lifters enough to hold the blade in place. Remove the remaining bolts (Figure 17 on page 27).

9. Clear the table and put the empty knife scabbard on the table.

10. Grasp the knife lifter assembly firmly while turning counterclockwise to release the knife from the knife bar. Slowly lower the knife down and to the right. Bring the left side out first and put the blade in the scabbard immediately.

11. Send the dull knife to the grinder.

1. Lower the knife bar.

2. Lock the paper deflector down by switching the hold down lever to the locked position (Fig. 18).

3. Raise the knife bar.

4. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)

5. Use the cutting stick puller to remove the cutting stick. Turn the cutting stick to a new surface.

6. Clear the cutter table and extension tables. Place chipboard directly under the knife to prevent nicking if the blade hits the table.

7. Check to make sure that all three (3) of the knife adjusting screws have been backed out, see

step 3 of Knife Removal section 8.1.2.1 on page 25.

8. Place the knife scabbard on the cutter table.

9. Remove the knife retainer screws holding the knife in the knife scabbard. Insert the knife lifters into the knife bolt holes on the knife (use the lowest holes) corresponding to the slots in the knife bar. Turn the threaded portion of knife lifters into the threaded holes in the knife until they contact the scabbard, then back off 1-1/2 turns.

10. Grasp the knife lifters, lift the blade, and insert the blade into the knife bar slot. Slowly guide the blade into the cutter right end first, then bring the left end in parallel to the knife bar. Raise the knife into the knife bar slot as high as it will go. Tighten the lifters to hold the knife.

NOTE: If the blade will not go in, either the lifters are screwed into the blade too far or the blade is not centered over the table, and the end of the blade is hitting the end stop in the knife bar

11. Insert the rest of the knife bolts and washers, snug tighten them, but don’t tighten completely. Be sure all bolts have washers. The correct washers are important for proper bolt clearances!
12. Replace the knife lifters with bolts and snug tighten.
13. Place a few sheets of paper across the table to cover the cutting stick.

NOTE: Before the knife bar is run down make sure the following is checked:

1. The (3) knife adjusting screws have been backed off completely.
2. The knife blade is raised as high as it can go in the knife bar over the entire length of the blade.

The paper deflector is locked down.

14. Unlock and turn the power on.
15. Lower the knife bar.
16. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
17. Turn the knife adjusting screws down, a little at a time, until the blade cuts through the paper evenly, over the entire length of the cut stick. Be sure the blade is parallel to the cutting stick, or one end may cut deeper than the other, causing uneven wear on the cut stick.

NOTE: When the knife is adjusted so it just cuts through the last piece of paper on the table evenly over the entire length of the cut stick, it is a good idea to turn each knife adjusting screw 1/4 turn tighter (clockwise). This can eliminate the need to readjust the knife after the very sharpest edge of the blade has worn off.

18. Tighten all the bolts.
19. Turn power on and send the knife to the “UP” position.
20. Make a test cut through a full lift of stock. Make minor adjustments by loosening the bolts and repeating steps 15 through 20.

NOTE: If the knife ends cut but the middle does not, you could have dips or uneven spots in either the knife or the cutting stick. These can be eliminated to some extent by laying 1/2" (13mm) wide strips of paper beneath the cutting stick to shim it up.

Assuming the proper bevel angle has been chosen for the material being cut, cut quality depends upon blade sharpness and surface finish. Three cut characteristics can indicate a blade needs sharpening:

1. Burnishing appears on cut face of lift.
2. The cut does not appear straight when viewed from the top.
3. The profile of the cut (side view) does not appear to be perpendicular to the table.

Other signs that a knife needs sharpening are:

The machine seems to strain while cutting. This strain can be heard in the hydraulic motor.

The knife makes a “rougher” sound as it passes through stock. Nicks are visible on the cutting edge of the knife.

The most appropriate bevel angle depends upon four factors.

The length of time desired between sharpening Physical properties of the stock being cut (hardness, impurities, density) Power output of machine Amount of clamp pressure applied

1. Length of Time Between Sharpening Under identical cutting conditions, knives with larger bevel angles will require sharpening less frequently than knives with smaller bevel angles. There is more material supporting the cutting edge of larger bevel angles.
2. Physical Properties of Stock In general a smaller bevel achieves a better quality cut. Hard, dense, and impure papers, however, will dull a small angle bevel quickly. Impurities may put nicks on the cutting edge. As a result, cut quality is lost quickly, and knives require sharpening often. Therefore, a larger angle bevel should be chosen for such materials. Soft materials can be cut with small angle bevels without adversely affecting sharpening frequency.
3. Power Output of Machine As the bevel angle increases, more power is required to push the knife through stock. If a bevel angle is too large for a machine, the machine may take excessive wear-and-tear and may stall part way through the cut cycle. Although the knife will require sharpening less often, the machine may incur costly damage.
4. Amount of Clamp Pressure Applied As clamp pressure increases, the pile density increases. As discussed in 2, above, more dense materials are harder to cut. This presents a dilemma. Higher clamping pressures are used to reduce draw when cutting with large angle bevels. While higher bevel angles increase the lifetime of the knife, high pressure clamping increases the material’s density and detracts from knife life. As a result, a compromise must be made between knife life and cut quality.

If your shop is large enough to purchase more than one set of knives, the following suggestions may be helpful. A set consists of 3 knives, one in the machine, one back up, and one at the grinder.

If you cut a variety of stocks (easy and hard to cut), purchase two sets of knives. One set should be beveled at around 21 0 and the other around 23 0 .

Use the smaller angle bevel to cut softer stocks at lower clamping pressures. Begin by cutting the most pure, easy to cut stocks. As the knife dulls, begin cutting the less pure of the softer stocks.

Use the larger bevel to cut harder more dense stocks at higher clamping pressures. Begin by cutting the softer and most pure of the hard stocks. Then move to cutting the harder and less pure of the hard stocks.

The following suggestions apply to those who can support only one set of knives. The bevel angle on the knives shipped with your machine was chosen for its versatility. It is not the ideal angle for every material, but these suggestions may improve the cut quality for those materials being cut with an inappropriate bevel:

First, cut the softest, most pure stocks at lower clamping pressures.

Move to the harder, more pure stocks at higher pressures. You may also need to reduce pile heights.

Softer, impure stocks are next, followed by the hard impure stocks.

Following these guidelines will decrease the frequency of knife sharpening while maintaining a quality cut as long as possible.

Suggestions for all:

If the machine seems to strain and cut quality is still good, reduce the pile height. You may also carefully apply glycerin to the bevel when cutting hard, coated stocks. Tie a cloth to the end of a stick; dip the stick in glycerin, and apply. Never apply by hand! In lieu of glycerin you may lightly rub white bar soap along the bevel. Lubrication will prolong the life of your machine and reduce maintenance.

If the machine seems to strain and cut quality becomes unacceptable, the knife should be changed.

Typical bevel angles vary from 26 0 to 19 0 . The most appropriate general-purpose bevel angle (23 0 ) was chosen for your machine. If your most common applications warrant a different angle, careful thought should be given before making the investment.

To prevent corrosion you received your knife coated with light oil. It should be REMOVED WITH CARE. While removing or installing a knife, be careful not to allow the edge to bump against the machine. Nicks will result. If a knife bolt is damaged, replace it. Always keep knife bolts securely tightened. Always use the heavy-duty knife bolt washers provided by Challenge. Failure to do so could result in scratching or marring of the clamp face. Store knives in a dry environment to prevent corrosion. Never attempt to service a knife in any way.

8.2 Lubrication

A clean, lubricated machine will cut more accurately, run longer, with less downtime, and fewer repairs.

Schedule lubrication maintenance early in the day. This allows the lubricants to work into the machine. Lubrication at the end of the day allows the lubricants to run off without any benefit to the machine. Clean off old, dirty excess grease. Wipe accumulated dust off valves, hoses, and connections. Built up dust increases operating temperatures and causes premature wear of all hydraulic components.

Oil and Grease Points WEEKLY.

Run the knife down and Lock Out the Power, see Power Lockout Procedure, page 5. All moving parts require lubrication. Remove all panel covers and look for all oil locations (marked with red paint). Make sure oil holes are not plugged and lubricate with a 30 weight oil. See the photos below for critical locations (not all locations are illustrated here). Notice that some are oil locations and some are grease points. Wipe off old and excess grease. Use a National Lubricating Grease Institute No. 2 consistency, extreme pressure grease.

Make sure to inspect the counter-weight chain, both connecting links, and the c-shaped channel for wear. If excessive wear is noticed, replace parts immediately. Be sure to oil the counter weight chain.

Replace all guards. Never operate cutter with any guards removed.

While lubricating, check pin locks to make sure they are in place and secure (Figure 19) there are a total of six. The bell crank pins do not require lubrication.

8.3 Hydraulic System

The Champion Series Cutters have both hydraulic cutting and hydraulic clamping operation. The cutter is powered by an electric motor coupled directly to a hydraulic pump. The pump has a fixed flow rate output of 10.5 GPM at 1800 PSI (max. system relief setting) at 1800 RPM.

A hydraulic cylinder powers the clamp. When the cut buttons are depressed, this cylinder pushes on a bell crank and brings the clamp down (or brings the clamp up to full hydraulic pressure if the manual foot clamp is down). A hydraulic cylinder connected directly to the knife bar also powers the cut. The knife sequence valve generates 1600 PSI of backpressure throughout the system to maintain full clamp pressure during the cut. One big advantage of the hydraulic system is the immediate return of the knife when the cut buttons are released. Instead of stopping in place, the knife immediately returns to the upper position.

The hydraulic fluid should be changed YEARLY or EVERY 1000 HOURS of operation.

The oil filter (Challenge part H-227-1) should be changed yearly or whenever any repairs are made to the hydraulic system. NOTE: Failure to change the oil when needed can damage the seals in the clamp and knife cylinders as well as the manifold.

Refill the tank with 15 gallons of an ISO (International Standards Organization) Viscosity Grade 46, rust, oxidation, and foam inhibiting hydraulic oil. NOTE: NEVER use Automatic Transmission Oil or Brake Fluid as a substitute for the correct hydraulic fluid. Dangerous operation conditions could result.

Check the level of the Hydraulic Reservoir WEEKLY or whenever the machine sounds like it is laboring (this could be due to low oil level).

Use only ISO (International Standards Organization) Viscosity Grade 46, rust, oxidation, and foam inhibiting, non-detergent hydraulic oil. Oils other than the recommended type will cause seals, cups, and O-rings to deteriorate. The proper hydraulic oil can be purchased in 5 gallon containers from your authorized Challenge Dealer using the Challenge part number: S-1991-3.

Before beginning, you will need (3) empty five gallon buckets, an oil pan, and a transfer pump. If oil is hot, wait until it cools.

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lock-out Procedure, page 5)
2. Remove the hydraulic breather cap (see Figure 30). Access the breather behind a cover plate on the hydraulic power unit cover.

3. Place the suction line of the transfer pump into the breather cap hole. Place the pressure line of the transfer pump into an empty five-gallon pail.
4. Turn on the transfer pump and fill the pail. Repeat until tank is empty.
5. Replace the oil filter. Place a thin film of new hydraulic oil on the seal of the new filter to insure a proper seal. Firmly hand-tighten the filter onto the filter head.
6. Fill the tank with recommended fluid until the level is 3/4” below the top of the inside of the tank.

NOTE: DO NOT OVERFILL. Overfilling may cause leakage when the hydraulic fluid is hot.

7. Reinstall the breather cap.
8. Before turning on the machine, make sure all hydraulic hose fittings are tight. Make sure the oil filter has been firmly hand tightened to the filter head.
9. Unlock and turn on the main power to the machine. Turn on the hydraulic motor by pressing both cut buttons once. Inspect the hydraulic system for leaks. If leaks are found, turn off main power to the machine and tighten any leaking fittings.
10. Repeat step 9 as necessary.

8.4 Line Light Adjustment

The line light comes on whenever main power is turned to the ON position. The light from each of two bulbs reaches the table after passing between the knife and clamp, (Figure 21).

Each light is focused with an adjusting screw mounted on the line light bracket, behind the console.

1. Tilt the console down by removing the two screws at the top.
2. Place a wide sheet of paper on the cut stick to view the line.
3. Using a 3/16” hex wrench, turn one of the adjusting screws until you see a 1/16-1/8” beam.
4. Similarly, turn the adjustment screw of the other bulb until one, continuous beam is seen across the cut stick.

8.4.1 Line Light Bulb Replacement:

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lock-out procedure, page 5)
2. Tilt the console down.
3. Remove the old bulb by lightly pushing bulb into the socket and turning it counterclockwise.

If the bulb is still hot, allow a few minutes to cool before changing.

4. Insert the new bulb into the socket and twist clockwise until the bulb locks into place.
5. Reattach the console.
6. Unlock and turn the power ON.
7. If necessary, adjust the line as above.

8.5 Cleaning

HYDRAULICS

1. The hydraulic fans and tank should be wiped off weekly to maintain maximum cooling of the tank and hydraulic oil.
2. The hydraulic manifold and fittings should be wiped off weekly.

TABLE

1. The dust should be wiped from the air blower inlet screen on a weekly basis. This will insure unrestrained flow into the blower and maximum flow out of the air jets.
2. The front table should be cleaned periodically to remove rust and wax buildup. This should be done using cleaners provided in the optional cutter care kit. (p/n 16077) Do not clean extension tables with these cleaners. Damage to their finish will result.
3. The extension tables should be cleaned either with a dry or damp cloth or a mild water based detergent.
4. The rear table cover may be cleaned with glass cleaner or a mild, water based detergent applied to a damp cloth. Some petroleum-based solvents may damage the Plexiglas cover.

CONSOLE

• The console should be cleaned with a mild water based detergent applied to a damp cloth or paper towel. Petroleum based solvents will damage the console.

MACHINE FRAME

1. The machine frame should be cleaned with a mild, water based detergent applied to a damp cloth.
2. Always be careful when cleaning around safety warning labels. Use limited amounts of cleaners in those areas.

8.6 Table Conditioning

The table of a paper cutter requires periodic maintenance to remove surface oxidation. Polishing is also required to provide a smooth surface for paper to move freely. The frequency of this maintenance will be determined by a number of factors. Among these are the humidity, environmental dust, handprints, liquid spills, and type of paper stock. We recommend the use of the Challenge Cutter Care Kit P/N 16077 for of your table care needs.

To prepare a new machine’s table, follow the procedure below:

1. Remove the rust-protective coating from the table with a solvent.
2. Remove all solvent residue from the table with a dry cloth. Continue until the cloth shows no sign of residue.
3. Apply a light coating of an SAE 10-weight non-detergent motor oil or equivalent to the table and allow it to penetrate for at least one hour.
4. Remove all excess oil from the table with paper toweling (not cloth) until the paper towel you are using shows no sign of oil.
5. Apply a paste wax (Challenge P/N 16078) to the table to seal the pores of the metal.
6. Note: Do not use a wax that contains a cleaning compound on the table. The cleaner contains microscopic abrasive particles that will cause wear between the table and the bottom of the backgauge. A silicone spray (Challenge P/N 16079) will show the same type of wear as the cleaner if the excess silicone is not removed. If the excess is not removed, the silicone spray has a substance that holds the silicone to the surface it is sprayed on that causes a black, gummy build-up under the backgauge. If a silicone spray is used, paper toweling must be used to remove the excess to prevent this wear and build-up.

To clean surface oxidation from a table, follow the procedure below:

1. Spray “Rust-B-Gone” (Challenge P/N 16080) on the table and allow it to dissolve the rust. Then remove it with paper toweling. Or, pour a small quantity of SAE 10-weight motor oil onto the table. Using a Scotch-Brite Pad or a 400 grit sand paper, polish the table following the “grain” of the metal until all oxidation is removed to your satisfaction.
2. Remove all of the oil from the table until the cloth you are using shows no sign of residue.
3. Apply a light coating of an SAE 10-weight non-detergent motor oil or equivalent to the table and allow it to penetrate for at least one hour.
4. Remove all excess oil from the table with paper toweling (not cloth) until the paper towel you are using shows no sign of oil.
5. Apply a paste wax (Challenge P/N 16078) to the table to seal the pores of the metal.
6. Note: Do not use a wax that contains a cleaning compound on the table. The cleaner contains microscopic abrasive particles that will cause wear between the table and the bottom of the backgauge. A silicone spray (Challenge P/N 16079) will show the same type of wear as the cleaner if the excess silicone is not removed. If the excess is not removed, the silicone spray has a substance that holds the silicone to the surface it is sprayed on that causes a black, gummy build-up under the backgauge. If a silicone spray is used, paper toweling must be used to remove the excess to prevent this wear and build-up.

8.7 Maintenance Adjustments

8.7.1 Squaring the Backgauge

To test the backgauge for squareness, place a small lift of paper against the left side of the backgauge (but not against the side guide) and make a cut.

PAPER

Now, leave the backgauge in the same position, flip the lift over and against the right side of the backgauge (but not against the side guide). Make another cut to see if any of the stock will trim off. Run two checks, one starting on the left and moving to the right, the other, moving from the right to the left. Trim in either sequence indicates the backgauge is out of square.

1. As machine wears, make sure the backgauge gibs are set properly first (see Backgauge Gibs), then follow steps 2 through 5.

NOTE: Gib adjustment is not necessary on initial machine setup because they have been adjusted at the factory.

2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Remove the rear table cover.
4. Loosen backgauge-locking screw (smaller head). Loosen the jam nuts on the backgauge squaring screws (see Figure ).

Squaring Screws

5. Back off the squaring screw on the side that the trim occurred and tighten the other. Make sure both screws are snug.

NOTE: If 1/8” of stock was trimmed off when checking for squareness, turning the proper squaring screw about one revolution will correct the problem. This relationship is constant, so turning the squaring screw 1/2 revolution will make up for about 1/16” of stock trimmed.

6. Replace the rear table cover. Unlock and reconnect the power.
7. Make another test. Continue to adjust and test until no trim occurs when testing in either sequence (steps 2 through 7).
8. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout Procedure, page 5)
9. Remove the rear table cover.
10. Tighten the jam nuts and lock screw.
11. Replace the rear table cover. Unlock and reconnect the power.
12. Check the backgauge for squareness.

If you are having trouble keeping the backgauge square, check for backgauge side play. Position the backgauge approximately 2” (50-55mm) from the rear of the table and turn off power.

Remove the rear table cover. From the back, hold each end of the backgauge and try pulling one end while pushing the other to rock it side to side (Figure 24. If there is noticeable side-to-side play in the backgauge, the gibs will need adjusting. Check for play at various positions on the table.

NOTE: There will be some front to rear movement between the backgauge nut and screw.

The backgauge has two gibs that ride on a iron rail underneath the table, (Figure 25). These are adjusted with setscrews that are held in position with jam nuts.

Setscrews and Jam nuts

To adjust:

1. Run the backgauge back to 23” (600mm).
2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Remove the rear table cover.
4. Always adjust the side gib first. Loosen all jam nuts and adjusting screws then tighten the front and rear screws.
5. Pull each end of the backgauge and try to rock it side to side as before to check for play.
6. Continue to adjust these two screws until there is no play.
7. Lock the screws in place with the jam nuts.
8. Snug up the middle two screws and lock in place with the jam nuts.
9. Snug up the bottom gib adjusting screws finger tight and lock in place with the jam nuts.
10. Replace the rear table cover. Unlock and reconnect the power.
11. Run the backgauge back and forth to make sure it does not bind. Readjust if necessary.
12. Check the backgauge squareness.

8.7.3 Backgauge Drive Belt Adjustment

If the backgauge motor runs but the backgauge does not move, or slips, the belt may need adjustment, (Figure 26).

Figure 26 – Backgauge Drive Belt

To adjust the belt:

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout Procedure, page 5.)
2. Remove the drive belt cover guard at the rear of the table.
3. Loosen the four socket head screws holding the motor to the mounting plate.
4. Slide the motor down to put more tension on the belt, or lift it up to reduce tension for removing belt.
5. If belt cannot be tightened, replace with a new belt.
6. Adjust the tension of the belt so that there is a 1/2”-3/4” (10mm) flex remaining and tighten the mounting plate socket screws.
7. Replace the belt guard cover. Unlock and reconnect the power to the machine.

8.7.4 Lead Screw Adjustment Nuts

If play is noted in the forward pillow block and thrust bearings, take up the play in the adjustment nuts by:

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
2. Remove the drive belt cover guard at the rear of the table.
3. Loosening the lead screw jam nuts, (Figure 27).

Figure 27 – Jam Nut Location

4. Snug up the inner nut to eliminate any play.
5. Tighten the nuts against each other.
6. Check the socket head bolts in the pillow block to make sure they are also tight.
7. Replace the belt guard cover. Unlock and reconnect the power to the machine.
8. Check the accuracy; it may need to be reset.

If the clamp piston bottoms in the cylinder before the clamp makes contact with the table, or if the clamp does not make full travel on the up stroke, the clamp cylinder may need adjustment. The clamp cylinder is located inside the frame, behind the left front enclosure door.

To adjust:

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
2. Loosen the jam nut.
3. Use the flats on the clamp cylinder shaft to turn the shaft into or out of the clevis as required, (Figure 28).

Flats on clamp cylinder shaft

4. Retighten the jam nut securely.
5. Close the front enclosure door.
6. Unlock and reconnect the power to the machine.

8.7.6 Clamp Parallel Rod

If the clamp is not parallel with the table:

1. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
2. Loosen the jam nuts on each end of the clamp connecting rod, (Figure 29).

NOTE: One of the jam nuts has left hand threads.

3. Using the flats on the end exposed, turn the connecting rod and align the clamp with the table. If a single sheet is placed under each end of the clamp and manually clamped, a level clamp will not allow either sheet to be pulled out.
4. Retighten the jam nuts securely.
5. Unlock and reconnect the power to the machine.

8.7.7 Knife Bar Gibs

The knife bar gibs are two plates on either side of the arch that guide and hold the knife as it cuts. If adjusted too tight the knife may not come down, or the gibs and knife bar could be damaged due to scoring. If too loose, you could get uneven or inaccurate cuts.

There are four socket setscrews with jam nuts on each side of the arch that adjust the gibs, (Figure 30). These should be adjusted only with the knife bar directly behind the bolts being tightened.

Knife bar gib adjustment screws

To adjust:

1. Lower the knife bar in Knife Adjust Mode.
2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Loosen all (8) jam nuts on the gib adjusting screws and back the screws out 1/2 turn.
4. Adjust lower (4) screws until snug - not tight to eliminate the air gap between the knife bar and gib. While holding the adjusting screws tighten those (4) jam nuts.
5. Unlock and reconnect the power to the machine, then raise the knife bar.
6. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
7. Adjust the upper (4) screws the same way the lower (4) were adjusted. Tighten the jam nuts.
8. Turn the power back on and cycle the knife several times. Recheck the gibs (repeat steps 1-7 as necessary).
9. Don’t over-tighten the gibs; this can score the knife bar.
10. If the knife bar and gets scored, remove only the burrs by scraping and then sanding smooth. Deep scores need not be removed.

8.7.8 Knife Cylinder Adjustment

The cylinder shaft is threaded into the clevis to adjust the position of the knife bar. When properly adjusted, the distance from the bottom of the knife bar, to the table with the knife bar in the down position should measure 1” (25.4 mm), (Figure 31).

To adjust:

1. Remove the knife as described the operator’s manual.
2. Enter Knife Adjust Mode and lower the knife.
3. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
4. Remove all covers and guards blocking access to the knife bar clevis (Figure 32).

Knife bar clevis

5. Loosen the knife bar clevis jam nut.
6. Loosen the setscrew on the collar mounted on the rod (Figure 34). Slide the collar down the shaft to the top of the cylinder. This collar is used to actuate the knife up and down proximity switches.

Knife cylinder collar.

7. Using the 1” flats on the knife cylinder rod, rotate the cylinder rod to move the knife bar up or down to the required height.

8. Lock the jam nut securely in place.
9. Readjust the collar. See section 8.10.1.1 Knife Up/Down Limit Switches on page 49.

CRUSH HAZARD! Knife and clamp will return to the up position when the power is turned on and the cut buttons are pressed for the first time. Keep hands and tools away.

10. Replace all covers and guards.
11. Install the knife; see section as described in the operator’ s manual.
12. Unlock and reconnect power to the machine. Allow the machine to run for a few minutes to work the air out of the hydraulic system.

8.8 Hydraulic Valve Adjustments

Several of the following tests require the machine to be operational for checking and adjusting. Be very careful that tools and other people are clear of moving parts and that the cutter is not accidentally operated while adjustments are being made. Disconnect the power and lock it out, (see Safety Precautions, page 5), whenever working on the machine unless the directions specifically require the machine to be powered.

For initial setup, adjust the valves in the following order:

1. Main System Relief Valve- 1800 PSI
2. Knife Down Sequence Valve- 1600 PSI
3. Clamp Up Sequence Valve- Adjust Visually
4. Electronic Clamp Control Valve- 1400max/400min PSI
5. Knife Flow Control Valve- See adjustment on page.

NOTE: Pressure settings fluctuate with oil temperature. Set pressures when the oil is hot.

8.8.1 Main System Relief Valve

This valve maintains the overall hydraulic pressure for the entire system. Factory setting: 1800 PSI.

Check Procedure:

1. Open the left access door on front of the cutter.
2. Turn the power on and, with a small stack of paper under the clamp, make a cut to hold the knife down on the cutting stick. Read the pressure off the main system pressure gauge (front gauge) while the knife is down. If the gauge does not read 1800 PSI, an adjustment is needed. You may need to send knife down in maintenance mode to read the gauge more easily.

To Adjust:

1. Loosen the lock nut on the relief valve. Use an Allen wrench to turn the adjusting screw. Turn clockwise to increase pressure, counterclockwise, to decrease pressure.

PINCH POINT—It will require two people to perform the following adjustment. One holds the cut buttons in and the other adjusts the valve screw. Be extremely careful to keep hands and tools away from moving parts. The only thing that has to be handled is the adjusting wrench! A possible pinch point exists between the clamp parallel rod and the top of the valve solenoids. Do not place hands or tools in this area if the machine is to be cycled.

2. Make a cut and hold the buttons in or go to knife down adjustment in maintenance mode to cycle the hydraulics. While reading the main system gauge, adjust the valve screw until you have the correct pressure.
3. Tighten the lock nut while holding the hex wrench in place.
4. Proceed to readjust the other valves.

8.8.2 Knife Down Sequence Valve

This valve controls the clamp and knife sequence. It keeps the knife up until after the clamp has made contact. It is mounted on the knife cylinder. Factory Setting: 1600 PSI.

NOTE: Main System Pressure must be set at 1800 PSI before making this adjustment.

Check Procedure:

1. Open the left access door on front of the cutter.
2. Press the cut buttons while reading the pressure on the main system pressure gauge (front gauge). The gauge should read approximately 1600 PSI as the knife is moving down (when bottomed, the gauge will jump to 1800 PSI showing the Main System Relief Pressure previously set).
3. If correct, proceed to check the remaining valves.

To adjust:

1. Loosen the lock nut.

2. Make a cut and hold the buttons in. While reading the main system gauge, adjust the valve until you have the correct pressure. Clockwise to increase, counterclockwise to decrease.

NOTE: The knife should not move until the clamp contacts the stock. If it does, you must increase the pressure.

3. Tighten the lock nut while holding the hex wrench in place.
4. Proceed to readjust the other valves.

8.8.3 Clamp Up Sequence Valve

(See Figure 33 on page 46)

This valve maintains clamp pressure so the clamp remains down until the knife has stopped in the up position. Factory setting: 800-1100 PSI.

Check Procedure:

1. Open the left access door of the cutter.
2. Press the cut buttons, and while reading the pressure on the main gauge (front gauge), release them. The gauge should read between 800-1100 PSI as the clamp is going up. There should be no clamp movement until the knife is stopped in the up position.
3. If correct, proceed to check the remaining valves.

To Adjust:

1. Remove the protective cap and loosen the lock nut on the clamp up sequence valve.
2. Make a cut and release the buttons. Read the main gauge as the clamp is returning. Adjust the valve for a reading of 800-1100 PSI.
3. Tighten the lock nut while holding the hex wrench in place and replace the protective cap.
4. Proceed to check the other valves.

8.8.4 Electronic Clamp Control Valve. (see the TC Operations Manual for further instructions)

8.9 Fuses (Skip this section if your machine has Circuit Breakers)

FIRE HAZARD. Replace only with same type and rating fuse.

The Champions each have a set of fuses. The fuses are located inside the main power box, (Figure 35). Check the label inside the cover for correct ratings for these fuses. Labels are reproduced with the drawings at the back of this manual in case those on the cover may be damaged or illegible.

8.10 Limit Switches

These tests require the machine to be operational for checking and adjusting. Be very careful that tools and other people are clear of moving parts and that the cutter is not accidentally operated while adjustments are being made.

Challenge Champion cutters incorporate proximity switches to detect stages of operation. These types of switches have no moving parts and are more reliable than contact switches.

NOTE: Adjust the switches in the following order:

1. Knife Up/Down Limit Switch
2. Hydraulic Up Limit Switch
3. Clamp Up Limit Switch

CRUSH HAZARD! When the limit switch is actuated, the clamp will return to the up position. Keep hands and tools clear.

8.10.1.1 Knife Up/Down Limit Switch

The knife up and knife down limit switches are mounted on separate brackets. An indicator light on the switch body comes on when the switch is actuated (proximity switches must be within 1/8” (3.2mm) to actuate). One collar activates both the up and down limit switches during the respective stages of operation.

To adjust:

1. Lower the knife bar. See section 2.12.4 Knife Adjust for directions on how to lower the knife bar.

2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Remove covers and guards blocking access to the limit switches.
4. Loosen the setscrew holding the collar in place on the knife cylinder shaft.
5. Move the collar (see Figure 36) until it is centered on the diameter of the proximity switch (limit switch). Tighten the setscrew in the collar to hold it in place. The distance between the collar and the proximity switch should be no more than 1/8” (3.2mm) of an inch.
6. Replace all covers and guards.
7. Unlock and reconnect the power to the machine.

8.10.1.2 Hydraulic Up Limit Switch

This switch is mounted on the left, rear leg at the base of the frame (Figure 37). An indicator light on the switch body comes on when the switch is actuated (proximity switches must be within 1/8” (3.2mm) to actuate). The switch senses the extension of the clamp cylinder at the top of its stroke. This stops hydraulic power to the clamp and knife. If the switch is not properly set, the knife and clamp cylinders will be under constant load (indicated by excessive heat and noise).

Hydraulic Up Proximity Switch

To adjust:

1. Make sure the clamp has returned to the upper position as far as it can go.
2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Loosen both lock nuts and adjust the switch until the indicator light on the switch lights up.
4. Unlock and reconnect the power to the machine.
5. Turn on the machine and press the cut buttons once to start the hydraulic motor.
6. Press the cut buttons to cycle the clamp and check clamp position.

8.10.1.3 Clamp Up Limit Switch

This switch is mounted inside the rear of the arch casting, (Figure 38). An indicator light on the switch body comes on when the switch is actuated (proximity switches must be within 1/8” (3.2mm) to actuate). The clamp trips it when the clamp moves to the up position. This switch prevents backgauge movement if the clamp is not up. It also diverts the air from the table when the clamp is down to prevent the stock from moving during a cut.

Clamp Up Proximity Switch

To adjust:

1. Make sure the clamp has returned to the upper position as far as it can go.
2. DISCONNECT THE POWER AND LOCK IT OUT! (See Power Lockout procedure, page 5.)
3. Loosen both lock nuts and adjust the switch until the indicator light on the switch lights up.
4. Unlock and reconnect the power to the machine.
5. Turn on the machine and press the cut buttons once to start the hydraulic motor.
6. Press the cut buttons to cycle the clamp and check clamp position.

14.0 Safety System Tests

14.0 Safety System Tests

CHALLENGE

Frequency of test: THESE TESTS SHOULD BE PERFORMED AT THE BEGINNING OF EACH WORK DAY.

Turn on the cutter and start the hydraulic motor (see operator’s manual for instructions). Enable the electric eye safety system.

Test #1: Using a 12 mm wide test piece, check the object detection capability of the electric eye system. Do this by waving the test piece throughout the electric eye beam area. The steady green and steady orange lights on the emitter side (RH) should change to steady red and flashing orange.

Test #2: Press both cut buttons to begin a cut cycle. During the downward motion of the knife or clamp, lean into the path of the electric eye beams. The downward motion of the knife and clamp should stop immediately, and the knife and clamp should return to the “up” position.

If the machine fails either test, DO NOT use machine. Repair or adjustment is necessary.

Please enter date and initials for both tests (make copies of this form if necessary).
