Turn the bar over –every time you sharpen the chain–and every time you replace the chain. This
avoids one-sidedwear, especiallly at nose and underside of the bar.
Regularly clean
1 = oil inlet hole
2 = oil passage
3=bar groove
Checking andReplacing the Chain Sprocket
Remove the chain sprocket cover, chain and guide bar.
Replace the chain sprocket:
after using two chains or sooner
if the wear marks (dimension deeperthan 0.02 in (0.5 mm) – the life of the a) on the spro
cket
are chain would otherwise be reduced.
The service life of the chain sprocket is prolonged if it is used with two chains in rotation.
Maintaining andSharpening Saw Chain
Correctly sharpened chain
A properly sharpenedchain slices throughwoodeffortlessly andrequires very little feed pressur
e.
Do not work with a dull or damaged saw chain as it will increase the physical effort required,cau
se
higher vibrations, produce unsatisfactory results and a higher rate of wear.
Clean the chain.
