In work, the saw is very convenient. Trees with a diameter of 30 cm fells without problems. The chain is well lubricated and the oil does not pour much. Fuel consumption is acceptable. Unfortunately it doesn't run well. The engine can be started only with the throttle fully depressed (in warm weather the first time, in cold weather 3-4 times). Hot starts with half a turn. Next season I will adjust the carburetor and I think the problem will be solved. In general, a good device.
