i've got two 5" Rigid orbital sanders. I relaly like them *except* they both are malfunctioning ... in the same manner. Here's the symptoms. When you start one, if you don't apply pressure right away to the pad, it starts spinning...fast. If you try and sand w/it in this condition it'll scar whatever it touches. To get around this, i'll stop the spinning on a piece of scrap and then move the sander to the good material. The other approach is to put the sander on the good material very quickly after turning it on -- before it starts spinning. works fine until you lift it up.
anyone know what's causing this? they have a 'lifetime' warrenty but there are no repair centers near me, so if there's an easy fix i'd like just fix it myself.
