All the negative reviews that I read earlier turned out to be with my saw . At the first start, everything was flooded with oil for the chain (the oil was bought specialized), I turned it down with a screw to failure in the minus, it got better, but it still pours a lot . The clutch did not work, the chain was constantly spinning at idle, removed a little idle, it worked . After sawing 10 logs, the bearing in the tire completely jammed, sawing became possible like a regular hand saw, very heavy, not convenient . I had to buy a new tire.
