Comprehensive Maintenance Tips for Bonsaii C237-B Shredder
1. Clean the Blades Regularly
Dust and debris from shredded materials can accumulate on the blades, reducing their cutting efficiency and causing jams.
How to Clean the Blades:
- Turn off and unplug the shredder.
- Remove the shredder head and use a soft brush or compressed air to remove debris from the blades.
- Run a lubrication sheet through the shredder to reduce friction and maintain smooth operation.
Pro Tip: Use shredder-specific lubricant sheets rather than liquid oil to prevent over-application and mess.
2. Empty the Waste Bin Frequently
An overfilled waste bin can cause shredded material to back up into the feed slot, leading to jams and motor strain.
Steps to Follow:
- Monitor the fill level using the transparent window on the 3.4-gallon bin.
- Empty the bin before it reaches full capacity.
- Clean the bin with a damp cloth to remove dust or debris.
3. Adhere to the Recommended Sheet Capacity

Overloading the shredder by inserting more than 6 sheets per pass can strain the motor and activate the overload protection mechanism.
How to Avoid Overloading:
- Always check the thickness of the paper stack before shredding.
- For thicker materials like credit cards, shred one item at a time to prevent jams.
4. Allow the Shredder to Cool Down
Continuous use beyond the shredder’s 10-minute runtime can cause the motor to overheat, triggering the thermal protection feature and halting operations.
Steps to Follow:
- After every 10 minutes of use, allow the shredder to cool for 30-40 minutes.
- Place the shredder in a well-ventilated area to speed up cooling.
5. Keep the Sensors Clean
Dirty sensors may fail to detect the presence of the waste bin, preventing the shredder from operating.
How to Clean the Sensors:
- Turn off and unplug the shredder.
- Use a soft, lint-free cloth to gently wipe the sensors near the feed slot and waste bin area.
6. Avoid Shredding Prohibited Materials
Shredding items like plastic sheets, thick cardboard, or metallic objects can damage the blades and motor.
What to Avoid:
- Laminated documents
- Plastic sheets
- Large staples or paper clips
Pro Tip: Remove staples and paper clips from documents before shredding to prolong blade life.
7. Regularly Inspect the Power Cord
A damaged power cord can interrupt operation and pose a safety hazard.
How to Inspect and Maintain:
- Check the cord for signs of fraying, cuts, or damage.
- Avoid wrapping the cord tightly, as this can weaken it over time.
- Replace the cord if any damage is found.
Common Maintenance Mistakes to Avoid
- Ignoring Overheat Warnings: Using the shredder continuously without cooling can cause irreversible motor damage.
- Skipping Lubrication: Neglecting to lubricate the blades can increase friction, reducing shredding efficiency.
- Using Improper Cleaning Tools: Avoid using abrasive materials or liquids that can damage the shredder’s components.
