I read on the Internet before buying that the Huter BS-45M may have problems with the oil supply. It's true, it didn't stop me, because I already have experience with similar defects. It happens much worse. Here, the carburetor also had to be adjusted and after a couple of short work processes, the chain had to be changed, because the regular one had stretched out. This misadventure ended. Now the tool works smartly, pulls well. Balanced and agile. There is enough power for a decent amount of p / m.
