Continuous Operation and Cool-down:
The shredder is designed for intermittent use. It can operate continuously for up to 2 minutes. After this period, the red overheat indicator will light up, and the shredder will automatically shut off to prevent damage. Allow the shredder to cool down for approximately 20 minutes before resuming operation. This helps prolong the life of the device.
