4.4 Overheat and Overload Protection
The shredder is designed with safety features:
- Overheat Protection: If the shredder operates continuously for more than 5 minutes, it will automatically shut off to prevent overheating. Allow the unit to cool down for approximately 40 minutes before resuming operation. An LED indicator will signal this state.
- Overload Protection: If too many sheets are inserted, the shredder will detect an overload. A red LED light will flash, and the machine will automatically eject the paper. Reduce the number of sheets and re-insert.
5. Maintenance
5.1 Emptying the Waste Bin
The transparent window on the waste bin allows you to monitor its fullness. When the bin is full, lift the shredder head using the handle and empty the shredded material. Re-insert the bin securely before operating the shredder.
5.2 Lubrication
Regular lubrication is essential for maintaining optimal shredder performance and extending its lifespan. Use Bonsaii lubricant sheets (Model: LS12) for best results.

- Ensure the shredder is in 'AUTO' mode.
- Feed one lubricant sheet directly into the paper entry slot, just like a piece of paper.
- Once the sheet has been completely shredded, switch the control to 'REV' (Reverse) for approximately 10 seconds to distribute the lubricant evenly across the blades.
- Return the switch to 'OFF' or 'AUTO' as desired.
