| Frequency | Action | |-----------|--------| | After every 10 minutes of shredding | Oil blades: Apply shredder oil in a zigzag across full width of entry slot. Run reverse for 5 seconds, then forward for 5 seconds. | | Weekly (heavy use) | Empty bin before it reaches 75% full. Overfilled bins cause paper to compact under cutter head, jamming reverse operation. | | Monthly | Clean optical sensors with compressed air. Vacuum paper dust from motor housing (dust causes overheating). | | Quarterly | Inspect power cord for cracks. Test thermal overload by running continuous shredding until motor stops – if it doesn’t stop within 2 minutes, thermal switch may be defective. | | Annually | Open gearbox, clean old grease, re-lubricate with plastic-safe grease. Check for cracked gears. |
Mineral oil-based, non-detergent, ISO viscosity 32–46. Commercial examples:
Shredders have a thermal fuse to prevent the motor from burning out. If the shredder runs for too long (exceeding its "duty cycle"), it will shut down automatically.
If the motor hums but nothing moves, you’ll need to clear the blades manually.
