5. Operating Instructions
5.1 Preparing for Cutting
- Unlock Blade: If the blade is locked, disengage the safety lock mechanism.
- Activate LED Guide: Press the power button for the LED cutting guide. A red laser line will appear, indicating the precise cutting path.
- Position Paper: Lift the cutting arm. Place the paper stack (up to the maximum capacity) onto the cutting bed, aligning the desired cut line with the LED guide. Use the measurement grid on the base for accurate positioning.
- Secure Paper: Lower the paper clamp handle firmly to hold the paper stack securely in place. This prevents shifting during the cut.
5.2 Performing a Cut
- Hold Handle: Grasp the cutting arm handle firmly with one hand.
- Execute Cut: With the other hand ensuring the paper clamp is secure and fingers are clear, pull the cutting arm down swiftly and smoothly in a single motion. Apply consistent pressure throughout the cut.
- Return Arm: Once the cut is complete, slowly raise the cutting arm back to its upright position.
- Remove Paper: Release the paper clamp and carefully remove the cut paper.
5.3 Maximum Cutting Capacity
The KW-Trio 3971 is designed to cut a maximum stack height of approximately 400 sheets of 70gsm paper or 40mm thickness. Do not exceed these limits to prevent damage to the blade or cutter mechanism.
6. Maintenance
6.1 Cleaning
- Regularly wipe the cutting bed and blade with a soft, dry cloth to remove paper dust and debris.
- For stubborn residue, use a slightly damp cloth with mild soap, then dry thoroughly.
- Do not use abrasive cleaners or solvents, as they can damage the surface and markings.
6.2 Blade Care and Replacement
CAUTION: The blade is extremely sharp. Handle with extreme care.
- A dull blade can lead to ragged cuts and require excessive force. Replace the blade when it becomes dull.
- Blade replacement should only be performed by trained personnel or by following the specific instructions provided with a replacement blade kit.
- Always ensure the cutter is unplugged and the blade is locked before attempting any blade maintenance.
6.3 Lubrication
Periodically apply a small amount of light machine oil to the pivot points of the cutting arm to ensure smooth operation. Wipe off any excess oil.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Ragged or uneven cuts | Dull blade; paper not clamped securely; cutting too much paper at once. | Replace blade; ensure paper clamp is tight; reduce paper stack height. |
| Blade sticks or is difficult to move | Accumulated debris; lack of lubrication; bent cutting arm. | Clean blade and pivot points; lubricate pivot points; inspect for damage (contact support if bent). |
| LED cutting guide not working | Power adapter not connected; power outlet issue; LED unit malfunction. | Check power adapter connection; try a different outlet; contact support if unit is faulty. |
