Maintenance
Emptying the Wastebasket
The 3.4-gallon wastebasket can hold approximately 180 sheets of A4 paper. A transparent window allows you to monitor the fill level.
- When the wastebasket is full, or the 'Bin Full Line' is reached, turn the shredder to OFF and unplug it.
- Use the portable handle to lift the shredder head off the wastebasket.
- Empty the shredded contents into a recycling bin.
- Replace the shredder head securely onto the wastebasket.

Overheating Protection
The shredder is equipped with an overheating protection system. If the unit operates continuously for more than 3 minutes (approximately 100 sheets) and becomes overheated, it will automatically shut off to protect the motor. The 'Overheat' indicator light will turn red.

If this occurs, allow the shredder to cool down for approximately 40 minutes before resuming operation. The 'Power' indicator light will turn green again when it is ready for use.
Troubleshooting
- Paper Jam: If paper jams, switch the control to REV (Reverse) to clear the paper. If the jam persists, turn the shredder OFF, unplug it, and carefully remove the paper manually.
- Shredder Not Starting: Ensure the shredder is properly plugged in and the control switch is set to AUTO. Check if the 'Overheat' indicator is red; if so, allow it to cool down.
- Shredder Stops Unexpectedly: This is likely due to overheating protection. Refer to the 'Overheating Protection' section under Maintenance.
