I have a green Bosch belt sander, which I was using to strip off some paint. One minute it was working fine; the next time I tried to use it, it would not start. I thought perhaps there was some thermal cut-out (though I had not been working it too hard), but even after a few hours rest it will not come to life.
Any ideas what this could be and whether it is terminal? Could it be something silly like dust in the switch or is it more likely to be new sander purchase time?
