I had a second day to try my new Milwaukee battery powered chain saw yesterday. Worked great except for the fact that the chain came off three times in rapid succession. I'm going to give it the benefit of the doubt for now, as I was cutting dense dry branches in a grove of spruce, and it was easy to jam branches of all sizes and angles into the chain/body, heck, I was bodily jammed in the branches myself (with multiple levels of head protection) just trying to access the branch where it connects to the tree. It was very dense. However if that chain derailure occurs again in more conventional settings I'm going to think there's a problem. Perhaps I need metalbender's pole saw. Though contrary to his notion about being tempted to cut one-handed, I'm getting a good workout using the chainsaw two handed, that thing is heavy.
