* First, I'm not a Wilson Jones tech.*
*** the following are for information only. ***
* Our friend keeps dropping off shreader after some problem with them. She always buys a new (different) one and leaves the junk to tinker with. These are some of the common problems I've encountered.
* Not moving. Totally jammed with paper! I had to use a blunt tool to back out the wheels. Careful as the blades are very sharp! It's best to use a wooden dowel to edge the blades back in the direction to loosen the stuck paper (be sure to unplug shreader!)
* Cracked case or inner frame. If it cracked under normal use then there is a design flaw or something fell on it. Only a complete swap out of equip will work as any glued on plastic parts will break again under load.
* Sensor is knocked off or damaged. Again, too much paper. Replace unit.
* Squeeks are caused by paper, staples, plastic (CDs) getting caught between the wheels and comb. Reversing helps, but some have to be physically removed. Again, unplug and check for the stuck debris. Remove with tweezer or needle nose plier. Careful of sharp blades!
* Squeeks will usually stop after a time as you continue to use the shreader. Debris will wear out and drop. Just keep in mind that whatever was shreaded when the squeeking started. That item should be avoided and only shreaded in small quantities at a time, alterating between regular paper.
* Check with the MFR if there is a lubricant, spray that is required. I use silicone spray sometimes when I have a lot of shreading to do. (Check with MFR)
* Final; Commercial shreaders tend to be large enough to get your hand or clothing stuck in the machine. Call for service to be safe.
