- Paper Jam:
- Slide the switch to the 'REV' (Reverse) position to clear the jam. This will push the paper back out.
- If the jam persists, unplug the shredder, carefully remove the shredder head, and manually clear any visible paper. Be cautious of the sharp blades.
- Avoid exceeding the maximum sheet capacity (10 sheets).
- Overheat Protection Activated:
- If the shredder stops working and the 'Overheat' indicator light is on (or the power light turns red), the unit has overheated.
- Unplug the shredder and allow it to cool down for approximately 40 minutes before resuming operation.
