The machine is a small beast. Quality and very powerful. It's worth its money. You put good chain and mixture oil in it at a ratio of 2.5% (25ml in 1000ml of gasoline). The only thing you have to do to make it cut strongly, after a few hours of use (2-3), is to take it to the mechanic to open the high speeds for it. That's when it becomes unstoppable.

The machine cuts quite well with a Carlton chain. It only cuts vertically, it does not have the ability to enter the trunk. It had a fall from the stairs and nothing happened, only the choke lever broke. I cut down a whole tree with a diameter of 10cm very easily. It is stable in cutting without vibrations. I will try it on larger trunks and will write more opinions
