Replacement Part List

NOTE: A new chain tends to stretch. Check the chain tension
frequently and re-tension as needed.
Nuts + Screws
Periodically check that all the nuts and screws are tight and
secure. Check that the collar that controls the telescoping pole
is intact and in proper working order.
Chain Sharpening
mWARNING! To ensure that the chain saw works safely
and eciently, it is essential that the cutting components are
well-sharpened. It is highly recommended to replace the
chain once it loses its ability to cut cleanly and safely.
It is possible, however, to sharpen the existing chain if the
sharpening is carefully performed. Any work on the chain
and bar requires specic experience and special tools. For
safety purposes, we recommend you contact an authorized

Sharpening is necessary when:
The sawdust looks like dust;
Cutting becomes more dicult;
The cut is not straight;
Vibrations increase.
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
les with the right diameter depending on the type of chain
(see “Chain Maintenance Table” pg. 16). You need a certain
amount of skill and experience to avoid damaging the cutting
Sharpen the chain as follows (Fig. 23):
Secure the bar rmly, with the chain mounted, in a
suitable vice.
Tighten the chain if it is loose.
Mount the le 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 le any projecting
parts with a at le, rounding o the edges (Fig. 23).
After sharpening, remove all traces of ling and dust
and lubricate the chain in an oil bath. Replace the chain
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 le 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
• Bent guide bar
