have quite a bit sawed, something cut longitudinally. The locking screw for the chain tension should wear möglist a little harder, but not by force. Have so far hardly have to follow the chain tension. Power it has adequately. The relatively high chain speed a brisk saws. Chain oil consumption is relatively low. Bought it to replace my old PKS1860 which cut much slower, but had done me on years of good service. The new saw is far better in all areas. Whether they hold out years, I do not know. If so, then necessarily a buy recommendation.
