I went to start working this morning, and my preferred saw (dewalt type 1) wouldn't start. I blew out the switch with canned air, opened up the switch cover and blew that out, checked the connections under the switch head. I checked the fuse, which looked good. I rotated the motor. I took the switch from my other dewalt (type 2) and tried that, and that didn't work. I check the brushes (and had a devil of a time getting them back in). I've had other problems like this with my type 2 dewalt, but never the type 1. Is there anything else I can do? My other dewalt (the type 2) that I haven't used in months since it had so much knocking and vibration won't start now either. So I have no saw at the moment. Anyway I can get one of them up and running? I've heard people talk about bypassing the switch, but I have no idea how that would be done. Any suggestions?
