I want to thank Satchmodog in this thread. I tore into mine. Since it didn't work I had nothing to lose. Blew is out with air as suggested, and sprayed contact cleaner. Then worked the trigger, and the rear speed adjuster. The saw now works again. Unfortunately I can't tell if the problem had something to do with the trigger switch or the rear speed control adjuster. I did them both at the same time before plugging it back in to test. Obviously these contacts are not sealed from dust. Thank you!

My problem started out exactly the same. Progressed to intermittently turning clear off. It seems related to the variable speed trigger switch. Now mine only runs on the lowest speed or will not come on at all. I have not used this saw all that much. Are these switches defective? Replaceable by DIY? Sending this somewhere of having it repaired by someone will more than likely cost more than a new one. But if I have to buy new it won't be Bosch again. This one is junk. [Bosch 1590 EVS] Can anyone suggest a known fix and a source for the part(s)? Thank you in advance.
