Avoid compacting large objects, like wine bottles or half-liter jugs, which will jam the mechanism.

Fill the bin completely before compacting. If bin is empty, wait till it is full before cycling unit.

If unit should stop midway thru cycle, try pressing firmly on the top of the door while turning key...sometimes you can free the jam.

Never substitute regular compactor bags for plastic trash can liners. They will invariably jam the mechanism!
