If my saw does not cut well, what can I do?

Change the chain. Check the air pressure for the saw lowering; add air to the air tank if needed. Check that the saw valve is engaging properly – replace if needed. Check that the safety valve opens and closes correctly – replace if needed.

If the chain is not lubricating well or not at all, what can I do?

Check the chain oil level – add chain oil if needed. Open the tank valve to increase the flow as needed. Check the automatic lubrication valve to see if the oil reaches the block and adjust the flow valve. If neither of these adjustments solves the problem, open the block and clean the piston.
