Last night after 15 mintues of steady (but not hard) use and then a period of cool down, I noticed next time I picked it up to make a cut it had gone single speed on me. The tool is 1-2 years old and has been used what I'd consider very little (homeowner). I've loved the saw so far and just want to get it fixed, I'm guessing its the switch and thought I'd check here first before contacting a warranty center. Any self diagnostics I can do on the switch? I'm not affraid to take it appart. I'd rather be able to order up a switch and have it sent to me than go an hour away to the warranty center anyway.
