Information about the guide bar and saw chain
WARNING: Use protective gloves when you
use or do maintenance on the saw chain. A
saw chain that does not move can also
cause injuries.
Replace a worn or damaged guide bar or saw chain with
the guide bar and saw chain combination recommended
by Husqvarna. This is necessary to keep the safety
functions of the product. Refer to
28 , for a list of replacement bar and chain
combinations that we recommend.

General information about how to sharpen the
cutters
Do not use a blunt saw chain. If the saw chain is blunt,
you must apply more pressure to push the guide bar
through the wood. If the saw chain is very blunt, there
will be no wood chips but sawdust.
A sharp saw chain eats through the wood and the wood
chips becomes long and thick.
The cutting tooth (A) and the depth gauge (B) together
makes the cutting part of the saw chain, the cutter. The
difference in height between the two gives the cutting
depth (depth gauge setting).
(Fig. 118)
When you sharpen the cutter, think about the following:
Filing angle.

It is not easy to sharpen a saw chain correctly without
the correct equipment. Use Husqvarna file gauge. This
will help you to keep maximum cutting performance and
the kickback risk at a minimum.
WARNING: The force of the kickback
increases a lot if you do not follow the
sharpening instructions.

4. Remove material from one side of all the cutting
teeth.
5. Turn the product around and remove material on the
other side.
6. Make sure that all cutting teeth are the same length.
