Turning Archive 2007
>I have one of these sanders. I have a modest air compressor( not the really small pancake kind), something like 4 cpf at 90 psi (max 135 psi), that I use with it. The problem is that the Grex spins like crazy and immediately sets off the air compressor, so that it more or less runs constantly. I thought I saw a post here that there is some kind of adjustment to slow it down. I did find a brass screw on the side, but turning it didn't seem to do anything. I could use some advice.
