When this shredder displays the overheat light, that indicates other problems. Mainly it's clogged and needs oil. Turn it upside down and plier the clumps out. Then apply oil liberably on both cutting edges inside. Turn it upright and squirt oil directly in the feed slot. This puppy loves oil and is a good machine.
Should have replaced my 11 yr-old Fellowes shredder sooner! Love both the price, the looks of this Staples shredder, and the shredder lubricant sheet, plus an Overheating indicator light! Goodbye to any shredder that needs lubricating oil still, and the horrifying sparks from an ever sluggerish motor. Now wish I would earn a few more free shredder lubricant sheets for writing this review.
