4. Maintenance
Regular maintenance ensures optimal performance and longevity of your shredder.
Cleaning:
- Always unplug the shredder before cleaning.
- Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Regularly empty the waste bin to prevent paper buildup and potential jams.
Lubrication:
To maintain shredding efficiency and extend the life of the cutting blades, lubricate the shredder regularly, especially after emptying the waste bin or after heavy use.
- Use shredder lubricant sheets or shredder oil specifically designed for paper shredders.
- For lubricant sheets: Insert one sheet into the shredder as you would a piece of paper.
- For shredder oil: Apply a thin line of oil across the paper entry slot. Then, run a few sheets of paper through the shredder to distribute the oil.
