The muffler is designed to keep noise levels to a minimum 
and to direct exhaust fumes away from the user. A muffler 
fitted with a catalytic converter is also designed to reduce 
harmful exhaust gases.

In countries that have a warm and dry climate there is a 
significant risk of fire. We therefore fit certain mufflers with 
a spark arrestor mesh. Check whether the muffler on your 
machine is fitted with this kind of mesh.

For mufflers it is very important that you follow the 
instructions on checking, maintaining and servicing your 
machine.

Never use a machine that has a faulty muffler.

Regularly check that the muffler is securely attached to 
the machine.

If the muffler on your machine is fitted with a spark 
arrestor mesh this must be cleaned regularly. A blocked 

mesh will cause the engine to overheat and may lead to 
serious damage.

A locking nut is used to secure some types of cutting 
attachment.

When fitting, tighten the nut in the opposite direction to the 
direction of rotation of the cutting attachment. To remove 
it, undo the nut in the same direction as the cutting 
attachment rotates. (CAUTION! The nut has a left-hand 
thread.)

When loosening and tightening the saw blade nut, there 
is a risk of injury from the teeth of the saw blade. You 
should therefore always ensure that your hand is shielded 
by the blade guard when doing this. Always use a socket 
spanner with a shaft that is long enough to allow this. The 
arrow in the diagram shows the area where you should 
operate the socket spanner when loosening or tightening 
the nut.
