Greetings, I recently bought a Ryobi 40V cordless 14" chainsaw to do some yard cleanup, including taking apart a couple of trees that came down. I have both a 4Ah and 6Ah battery for it, and regardless of which battery I'm using the chainsaw stops and refuses to restart after a couple of minutes of use (and I do mean a couple of minutes.) Pulling and reinserting the battery will let it start up again, for another 30 seconds or so. Ryobi support was completely unhelpful. Is this intended design, with the saw stopping because it's getting too hot, or do I have a defective saw? Any advice would be helpful. Thanks!
