I bought a 10 inch battery powered chainsaw. I haven't had the gumption to try to use it yet, it has so many scary warnings, plus it turns out that the little oil tank will leak out within 40 minutes and probably splatter on me. So I feel now like I need to prepare a plan of where I want to trim. It also says to practice using sawhorses first. I know where one sawhorse is, not sure where a second one is, but I did find and secure a small downed tree branch to practice on. Also the booklet warns that saplings are particularly dangerous - and that is exactly what I want to use the chainsaw for. I hope I screw up my courage enough to go out and try it today.
