If the chainsaw does not cut properly the most common cause is a dull or worn cutting chain. Try replacing the cutting chain, if that solves the problem the old cutting chain can be taken to a servicing dealer to be sharpened.

If the chainsaw does not cut properly the chain tension might not be set correctly. There is an adjustment screw which is loosened or tightened to provide the correct chain tension. If the adjustment screw is too loose, the chain will be loose and not make good contact with the wood. If the chain is too tight the chain might not rotate at the right speed and then the saw does not cut properly.
If the chainsaw does not cut properly, the chain bar might be bent or worn out. The chain must slide easily and freely around the chain bar. If it doesn't, replace it. The chain bar is lubricated by chain oil which is fed from a reservoir. Be certain to fill the reservoir with chain oil every time the tank is filled.
As the clutch assembly pads wear out they no longer can put enough pressure against the clutch drum. When the engine speeds up the chain also speeds up, but as the chain is placed against the log the friction of the chain overcomes the decreased friction of the clutch pads and the chainsaw does not cut properly. The solution is to repair or replace the clutch assembly.
Chainsaws are equipped with a clutch band, a steel band that wraps around the clutch drum and is activated by the emergency stop lever. If the lever does not disengage completely the chain cannot reach full speed and the chainsaw does not cut properly. Check to be sure the stop lever is disengaging completely. Adjust the clutch band if necessary.
