Could anyone try to help me identify this problem. I bought my first chainsaw a couple days ago, it's a craftsman chainsaw 16". So I was cutting with it and then the chain decided to stop spinning. I have taken the chain off and checked everything, I even took a paper clip and lightly checked the chain frame by running it along the edges that it lays on to see if anything managed to get caught it's fine, the thing at the end of the saw spins really well to. So I thought it might have been the safety thing at first. So I push the safety out and then pulled it back in to reset it. That seemed to get it to work, so I cut a log in half with it and then went to cut again and it would not spin again. But something I noticed after I did safety reset first was when I started the chainsaw the chain was spinning on its own without having to enable it to spin. Also it's brand new not used!
