I took a saw that year, started sawing an apple tree and my native chain became dull almost immediately, I thought that there was not enough power, but as it turned out, the whole thing was in the chain, I had to go for a new one, and after that there were no problems that I didn’t saw only with this saw , has never let me down, there is enough power, light, comfortable, the length of the saw blade is enough. I only advise you to dilute the fuel mixture correctly, buy good oil, do not keep this fuel mixture for a long time and the saw will work for a long time. For those who choose a chainsaw - I advise everyone!
