An authorized service center will sharpen the chain using the
right tools to ensure minimum removal of material and even
sharpness on all the cutting edges.
If you sharpen the chain yourself, use special round-section
files with the right diameter depending on the type of chain
(see "Chain Maintenance Table" pg. 15). You need a certain
amount of skill and experience to avoid damaging the cutting
edges.
Sharpen the chain as follows (Fig. 21):
• Secure the bar firmly, with the chain mounted, in a
suitable vice.
• Tighten the chain if it is loose.
• Mount the file in the guide and then insert it in the tooth at
a constant angle from the cutting edge.
• Sharpen in a forward motion a few times and repeat this
on all the cutting edges facing the same way (right or left).
• To move the chain forward, use a screwdriver.
• Turn the bar over in the vice and repeat on all the other
cutting edges.
• Check that the depth limiter tooth does not stick out
farther than the inspection tool and file any projecting
parts with a flat file, rounding off the edges (Fig. 21).
• After sharpening, remove all traces of filing and dust
and lubricate the chain in an oil bath. Replace the chain
whenever:
– The length of the cutting edges decreases to 5 mm
or less;
– There is too much play between the links and the rivets.

Guide Bar Maintenance
When the guide bar shows signs of wear, turn it over on the
saw to distribute the wear for maximum bar life. Feathering or
burring of the bar rails is a normal process of bar wear. You
should smooth such faults with a file as soon as they occur.
Replace a bar with any of the following faults:
• Wear inside the bar rails permitting the chain to lay over
sideways
• Bent guide bar
• Cracked or broken rails
• Spread rails
Turn the saw over, check the underside of the guide bar, and
make sure that the lubrication holes and chain groove are free
from impurities.

Chain Sprocket
Regularly check the condition of the sprocket and replace it
when wear exceeds 0.5 mm (Fig. 22).
Do not mount a new chain with a worn sprocket or vice-versa.
