Cutter Maintenance:

When you notice the shredder is experiencing difficulty shredding, or gets jammed easily, then it's probably time to oil. If you use your shredder occasionally, then oiling your shredder may only be necessary every two months to maintain good performance. If you use your shredder a lot, however, then your best practices are to oil your shredder every time you empty the waste bin. Get your shredder lubricants by clicking here.
