Please see some trouble shooting tips below to try -
* Unplug the machine from the wall and check for anything stuck in the teeth. If so, can this be removed? Do not pull anything part as this will void the warranty.
* The shredder needs to be oiled regularly - (ideally with each new bin) to keep the machine functioning. You can use oil sheets, or squirt oil in an S fashion on a sheet of paper and place this through the unit.
* Either use a blower (or vacuum) through the unit itself to see if this can remove some of the paper dust.
