Cleaning
Regular cleaning helps maintain the shredder's efficiency.
- Always unplug the shredder before cleaning.
- Wipe the exterior of the shredder with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Occasionally, use shredder oil sheets or liquid shredder oil (applied to a sheet of paper) to lubricate the cutting blades. Follow the instructions provided with the shredder oil.
7. Troubleshooting
Paper Jam

Figure 5: Effortless Jam Clearing and Enhanced Safety Protection. This image illustrates the auto-start and reverse function for quickly removing paper jams, and the lid safety lock that stops shredding when the head is opened.
If a paper jam occurs:
- Set the slide switch to the REV position. This will reverse the cutting blades, allowing you to pull the jammed paper out.
- If the paper does not clear, switch to FWD briefly, then back to REV. Repeat this cycle a few times.
- If the jam persists, unplug the shredder and carefully remove the shredder head. Manually clear any visible paper from the cutting blades using tweezers or pliers. Do not use your bare hands.
- Once cleared, replace the shredder head, plug it in, and resume operation.
Overheat Protection

Figure 6: Overheat Protection. This image shows the shredder's indicator lights, demonstrating that the shredder automatically stops after 4 minutes of continuous operation to prevent overheating. It indicates a 30-minute cooldown period.
The Bonsaii C277-C is equipped with an overheat protection system. If the shredder operates continuously for approximately 4 minutes, it will automatically shut down to prevent damage from overheating. The 'Overheat' indicator light will illuminate.
- If this occurs, turn the shredder off and unplug it.
- Allow the shredder to cool down for at least 30 minutes before resuming operation.
- After the cooling period, plug it back in, and the shredder should function normally.
