I've used it quite a bit with no problems. I figure it takes a normal 6 inch chain, which I've seen at Lowe's. It's weird that it doesn't use chain oil. But it hasn't presented a problem.
I have a cordless 6 inch chainsaw that I use for brush. Pretty handy. I think it cost like 80 bucks. Just fits in the hand, nothing big but it's pretty powerful.
We were supposed to have had our last 100 degree day a couple of weeks ago.but it keeps right on a nudging that mark still. Although this week is showing a lot of low 90's in the forecast.
