NOTE: A new chain tends to stretch. Check the chain tension 
frequently and re-tension as needed.
Nuts and Screws
Periodically check that all the nuts and screws are tightened 
securely. Check that the telescoping lock and assembly lock 
are intact and in proper working order.
Chain Sharpening
mWARNING! To ensure that the saw works safely and 
eciently, 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 specic 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 dicult;
•  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” on pg. 17). You need a certain 
amount of skill and experience to avoid damaging the cutting 
edges.
Sharpen the chain as follows (Fig. 25):
•  Secure the bar rmly, with the chain mounted, in a  
suitable vise.
•  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 vise 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. 25).
•  After sharpening, remove all traces of ling 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.
