Continuous Operation
This heavy-duty shredder is designed for continuous operation for up to 40 minutes. After this period, a 60-minute cool-down period is recommended to prevent overheating and ensure longevity. During a 40-minute cycle, it can shred approximately 5230 sheets of A4 paper.

Security Level
The BONSEN S3105 provides P-4 security level cross-cut shredding, reducing paper into small pieces of 5/32 x 1-12/32 inches (4 x 35 mm). This ensures your confidential information is securely destroyed.

Waste Bin Management
The shredder features a large 9-gallon pull-out waste bin, capable of holding up to 650 sheets of shredded paper, reducing the frequency of emptying. The "Bin Full" LED indicator will flash when the bin needs to be emptied.

Maintenance
Lubrication
To maintain optimal performance and extend the lifespan of your shredder, it is recommended to lubricate the shredder blades regularly. Use Bonsen shredder lubricant sheets (Model: LS50) or a suitable shredder oil. Simply insert a lubricant sheet into the shredder as you would a regular piece of paper every few shredding cycles. This helps reduce static dust and improves shredding efficiency.
Cleaning
Periodically clean the exterior of the shredder with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the power is disconnected before cleaning.
