Keeps stopping with overload light on. How can this be fixed

The most likely cause is that the shredded paper, has tightly wrapped itself in the blades. One possible cause is by shredding labels (like Avery Labels) or any paper which has adhesive on it. (Causes it to attach the cut pieces to between the cutters.) It reaches a point where there is so much bound up on the blades that even a single sheet of paper will cause an overload. The fix is simple to describe, but difficult to accomplish. You must go in and manually remove all of the paper bound up in the blades. It's not easy, I found that using a needle nose pliers worked best. Lot of digging and tugging (paper will pack between the blades very tightly). Sometimes a small, slotted screwdriver will aid in being able to pry out bits and pieces (it's not going to come out in anything but small chunks; at best). Don't forget to unplug your shredder before you start; those blades are sharp. This happened several times with my last shredder *Royal), but not once with my current shredder (Fellows). I tend to believe that the better quality shredders are worth the extra money. But any shredder will become a problem if you shred labels (like Avery) or paper products that has adhesive on it. (Another common mistake is shredding junk mail that has any kind of adhesive associated with it. Best to open and check first.) One other thing, ALL shredders need to be oiled on a regular basis. They make special oil for this, you can usually find small bottles of it at Wally World or the like. Best practice is to squirt some shredder oil in a serpentine pattern. over a piece of paper to be shredded and run it through. Do this whenever you empty the shredder bin. (Important for the life of your shredder.)
