The muffler is designed to keep noise levels to a minimum 
and to direct exhaust fumes away from the user.

In areas with a hot, dry climate there is a high risk of fires. 
These areas are sometimes subject to government rules 
requiring among other things the muffler must be 
equipped with an approved type of spark arrestor mesh. 
(14)

When fitting the mesh, make sure that the mesh is 
inserted in the right position.  If necessary, use the 
combination spanner to insert or remove the mesh.

This section describes how to choose and maintain your 
cutting equipment in order to:

•

Reduce the risk of kickback.

•

Reduce the risk of the saw chain breaking or jumping 
off the bar.

•

Obtain optimal cutting performance.

•

Extend the life of cutting equipment.

•

Avoid increasing vibration levels.

•

Only use cutting equipment recommended by us!  
See instructions under the heading Technical data.

•

Keep the chain’s cutting teeth properly 
sharpened!  Follow our instructions and use the 
recommended file gauge. A damaged or badly 
sharpened chain increases the risk of accidents.

•

Maintain the correct depth gauge setting! Follow 
our instructions and use the recommended depth 
gauge clearance. Too large a clearance increases 
the risk of kickback.

•

Keep the chain properly tensioned!  If the chain is 
slack it is more likely to jump off and lead to increased 
wear on the bar, chain and drive sprocket.

•

Keep cutting equipment well lubricated and 
properly maintained!  A poorly lubricated chain is 
more likely to break and lead to increased wear on the 
bar, chain and drive sprocket.

The only way to avoid kickback is to make sure that the 
kickback zone of the bar never touches anything.

By using cutting equipment with ”built-in” kickback 
reduction and keeping the chain sharp and well-
maintained you can reduce the effects of kickback.

The smaller the tip radius the lower the chance of 
kickback.

A chain is made up of a number of links, which are 
available in standard and low-kickback versions.

To maintain the safety features of the cutting equipment, 
you should replace a worn or damaged bar or chain with 
a bar and chain combinations recommended by 
Husqvarna. See instructions under the heading Technical 
Data for a list of replacement bar and chain combinations 
we recommend.

•

Length (inches/cm)

•

Number of teeth on bar tip sprocket (T).

•

Chain pitch (inches). The spacing between the drive 
links of the chain must match the spacing of the teeth 
on the bar tip sprocket and drive sprocket. (15)

•

Number of drive links. The number of drive links is 
determined by the length of the bar, the chain pitch 
and the number of teeth on the bar tip sprocket.

CAUTION! The muffler gets very hot during and after 
use. This also applies during idling. Be aware of the fire 
hazard, especially when working near flammable 
substances and/or vapours.

IMPORTANT! No saw chain design eliminates the 
danger of kickback.
