- OPERATION
The trimmer must only be used by trained and qualified personnel. The trimmer must be used only for trimming material for which it has been designed. For recommended maximum cutting thickness see page 14.
- The trimmer should be positioned on a level surface in an area with adequate lighting and enough work space for feeding materials. Connect the power cord to the AC outlet and turn the Power switch to the ON position. The machine should be operated from the front of the machine only.
- To begin trimming material, position the material to be trimmed on the front feeding table (Fig. 5-1) and measure the cut by using the scales present at either side of the feed table or by the guideline. Do not lean against or put any object on the feeding table during trimming.
- When the material is properly positioned press the activation bar (Fig. 5-2) anywhere along the length of the trimmer to activate the cutting blade or step on the foot pedal (Fig. 5-3) to activate the cutting blade. The material can now be removed or repositioned for another cut.

Quick start
- Have it installed: A trained service technician should install the RET-2502. Use it in a protected, well lit area at 64F to 95F and 30% to 80% humidity.
- Assemble the stand: Two people should do this. Attach the lower cross bar to the left and right floor stand side frames with the M8x55 screws, then slide in the holder rods and fit the E-rings.
- Fit the protection plate: Attach it to the front of the upper cross bar with the supplied screws, with the table adjustment pin upward.
- Power on: Connect the cord to the AC outlet and turn the Power switch ON.
- Position the material: Place it on the front feeding table and measure the cut with the scales on either side or the guideline. Do not lean on the table or put objects on it.
- Cut: Press the activation bar anywhere along the trimmer or step on the foot pedal. Then remove or reposition the material.
- Stay within capacity: Check the recommended maximum cutting thickness on page 15. Thicker material may dull or damage the blade.
Troubleshooting
| Problem | Likely cause | Fix (from the manual) |
|---|---|---|
| RET-2502 shows no life at all when the power switch is flipped | The plug may be loose, the switch may sit at "0", or the main power fuse may have burnt out. | Check the cord first, move the switch to "1", then swap the burnt main power fuse if the unit is still dead. Page 14 |
| Lamp is lit but pressing the activation bar does nothing, and LED3 on the PCB is dark | A blown fuse on the electronic board stops the cutter. | Unplug the trimmer, remove the left panel and put in a new 2A fuse. Page 13 |
| Lamp is lit but the blade stays put and LED3 on the PCB glows | One of the limit switches, left or right, has come loose. | Replace the left or right micro switch. Call Royal Sovereign if the cutter still stays still. Page 14 |
| Cuts feel rough and scrap is piling up inside the trimmer | A lot of scrap material has collected under the safety cover. | Unplug the unit, take off the safety cover and clear the scrap with an aspirator or compressed air. Page 13 |
| Blade seems dull or damaged after trimming a thick stack | The stack was thicker than the maximum listed for the model, which can dull or damage the blade. | Stay within the recommended trimming thickness in section 9.2 and see page 14 for the limit. Page 15 |
