Chain Sharpening
mWARNING! To ensure that the 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

(1-866-766-9563).
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 by yourself, it's recommended to
purchase Sun Joe

24V-CSSHRP-LTE chain saw sharpener,
which can be powered by the same 24V iON+ battery with this
cordless chain saw. Visit sunjoe.com or call the Snow Joe

Otherwise, use special round-section les with the right diameter
depending on the type of chain (see “Chain Maintenance Table”
pg. 23). You need a certain amount of skill and experience to
avoid damaging the cutting edges.
Sharpen the chain as follows (Fig. 22):
• 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. 22).
• 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.
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 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.
