Quick start

  1. Level the machine with its four levelers, then plug it into a nearby 115 VAC outlet on a 20 A circuit.
  2. Switch on the main power (left side of the stand, under the table). The pump and table light come on.
  3. Set the side gauge and back gauge tangent to the radius on the die, with the back gauge square to the side gauge (power off, top cover open).
  4. Load the stock using the jogging aid. Jog it against the side gauge, then push and jog it against the back gauge.
  5. Keep hands away from the knife and plunger and always use the jogging aid while cutting.
  6. SCM: Press and hold the foot switch to cut, and release it after the knife stops moving down.
  7. Lubricate weekly: gib lube on the gib and both sides of the dovetail, light machine oil on the knife return rod and springs and the rear pillow blocks.

Troubleshooting

ProblemLikely causeFix (from the manual)
The machine will not cyclePower cord disconnected, blown fuse, or disconnected wiresCheck the power cord connection, check and replace the fuse, and check wiring. Fuse checks are for trained service personnel (SCM only). Page 40
The machine will not switch onPower cord disconnected, blown fuse, defective power switch, or loose wire connectionReconnect the power cord, replace the fuse, and have a technician check the power switch and wiring. Page 40
The machine switches on, but the table lamp is outBurned-out bulb or loose wire connectionReplace the bulb and check the lamp wiring. Page 40
Knife down motion is sluggish or erraticLow hydraulic fluid, hydraulic leak, insufficient voltage, dry dovetail, or misadjusted dovetail gibCheck the hydraulic fluid level (SCM), look for leaks, make sure the machine is on a 20 A circuit without too many other machines, lubricate the dovetail with gib lube, and adjust the gib. Page 40
Knife return is sluggish or erraticKnife return spring(s) worn out or improperly adjusted, dry dovetail, or misadjusted dovetail gibAdjust the return spring length to between 13.6" and 14" (page 21), lubricate the dovetail, and adjust the gib with a .002" feeler gauge. Page 40
Cannot adjust knife to dieKnife and die are not a matched pair, or the knife is not aligned in its keywayUse a matching knife and die and seat the knife correctly in the keyway before adjusting. Page 40

Frequently asked questions

How thick a pile can the Challenge single cornering machine cut?

The maximum pile height is 4" (10 cm). Table height is 35" and the footprint is 20 x 24" (page 10).

How long can a straight diagonal corner cut be?

Up to 1" when cutting 4" thick piles. Piles 2" thick and below can be cut at a 1-1/4" diagonal. The length is set by adjusting the side gauge (page 18).

How do I set the knife when changing the knife and die?

Adjust the knife with its setscrew until the cutting edge is 1/8" above the surface the die mounts on, then adjust the die so it contacts the knife at all points, using tissue paper between them to check clearance (page 17).

What power does the hydraulic SCM need?

The SCM uses a 1/2 HP motor on 115 V, 15 A, single phase, 60/50 Hz, with a 20 A service size. If the pump stalls or runs sluggishly, test the line voltage (page 10, page 12).

What is the part number of the knife hold-down block?

The knife hold-down block is part 8315, included in the tool kit along with the 83014 jogging aid and 6629 gib lube (page 8).
