Rick,

This TS4500 shredder had been discontinued for more than 5 years. The factory did not make any spare parts for this model.

Thanks,

It sounds like you may have a gear with a broken tooth you should contact the manufacturer to get more info. Usually when this is the case it will shred good for only a few revolutions and then reversing backs the gear up to a position that allows it to turn the cutters until it once again reaches the area where tooth is missing.
