1. Make sure that the unit is securely plugged into a working outlet / socket.
2. If you have been continuously shredding for an extended period of time, the unit may have overheated and the thermal protection feature has been activated to shut off the machine. If this happens, switch off the unit for at least 30 minutes/1 hour for it to reset before continuing.
3. Make sure the wastebasket is properly plugged into the machine.

1. Be sure the shredder is set to the “Auto/On” mode and NOT in the “Reverse” mode.
2. The feeding entry of the shredder is blocked or jammed. Please refer to User Manual.  
3. Te gears driving the cutting blades may be stripped or worn out. A shredder with a stripped gear will typically spool at a high pitch sound. Shredding beyond the specified sheet capacity or shredding materials not intended for proper use, will strain the machine and quickly wear and may break internal components. Please refer to the Operation section of your User Manual for more information.

1. The shredder probably has a paper jam. Please refer to “How to Clear a Paper Jam”
2. When set to the “Auto/On” (Standby) mode, the green “Ready” indicator light will turn on. This means that the shredder is ready for use. The shredder will automatically start when paper is fed. The shredder is not supposed to constantly run when in the “Auto/On” mode.
3. The sensor in the paper feed entry is not being activated. A sensor which activates the shredder is located in the center area of the feed entry. When ready to shred, be sure to insert material directly into the center area to start the machine.

1. Insert a filing folder or any rigid sheet of cardstock (old greeting card, sheet torn from cereal box, or a couple index cards) directly into the center of the feed entry while applying force to help push the jammed paper through. This will usually clear any paper blockage or other obstructions.
2. With the shredder unplugged, you may use a set needle-nose pliers or tweezers to remove the blockage. 
3. Use the “Reverse” mode to back up and remove the stuck paper. The shredder will back up and loosen the jammed paper. If required, you may need to tug and remove several sheets to effectively clear the machine. When jammed paper is removed, return the shredder to the “Auto/On” mode to resume shredding. NOTE: Do not activate reverse function while shredding Credit Cards or CDs.
