Items Suitable for Shredding with the Bonsaii C149-C Shredder

1. Paper (Stapled or Clipped)
The Bonsaii C149-C is primarily designed for shredding paper, and it does so efficiently. What sets it apart is its ability to shred up to 18 sheets of standard A4-sized paper (80g/m²) in one go. Thanks to its robust cutting mechanism, you don’t have to remove staples or small paper clips before shredding. This feature saves you time and effort when dealing with bulk documents.
Key Tip:
- Avoid overloading the shredder beyond its 18-sheet capacity to prevent jams and overheating.
2. Credit Cards
This shredder is capable of shredding credit cards, which is crucial for securely disposing of expired or unwanted cards. The cross-cut mechanism ensures that sensitive information on the card is completely destroyed, offering peace of mind against data theft.
How to Shred:
- Insert the credit card into the designated feed opening. Ensure only one card is shredded at a time to prevent damage to the machine.

4. Thin Cardboard
Thin cardboard, such as packaging material from small boxes, can also be shredded. This feature is ideal for reducing the volume of recyclable waste or securely disposing of packaging with sensitive information.
Note:
- Fold thicker cardboard pieces to ensure they fit within the 5.5-inch feed opening.

Why It’s Important:
- Shredding bills and receipts helps prevent identity theft and unauthorized access to financial data.

Materials to Avoid
While the Bonsaii C149-C is a heavy-duty shredder, there are certain materials it cannot handle to avoid damage or malfunction. These include:
- Adhesive tape: Sticky residues can clog the blades.
- Fabric or textiles: These materials can tangle in the shredder mechanism.
- Plastic films: Thin plastic sheets may not shred properly and could damage the machine.
- Metal objects: Larger metal pieces like binder clips or coins should never be inserted.
Shredder Maintenance Tips
To ensure your Bonsaii C149-C continues to perform at its best, follow these maintenance tips:
- Regular Lubrication: Use shredder lubricant sheets or Bonsaii shredder lubricant packs to maintain the blades. Run the lubricating sheet through the shredder as per the manual’s instructions.
- Empty the Basket Regularly: The shredder’s 23-liter basket can hold a significant amount of shredded material, but it’s essential to empty it before it overflows. A full basket can cause jams and affect performance.
- Avoid Overheating: The machine has an overheat protection feature. If it shuts down due to overheating, allow it to cool for approximately 20 minutes before resuming operation.
- Handle Jams Correctly: In case of a paper jam, use the “REV” (Reverse) function to remove the stuck material. Repeat this process if necessary.
