I have a 40cc Craftsman 18" chainsaw, and was cutting and the chain stopped moving. Earlier it would rotate freely when I started it, even without pulling the trigger. Now it does not move at all. I'm nervous to pull it too hard, and wonder if it's just some safety setting that I accidentally triggered. Any advice?
My saw has a brake that can protect me in case of a kickback. It sits in front of my left hand. Push forward to engage, pull back to release.
Or it could be a maintenance issue:
