cutter.

Muffler
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 screen. Check whether the muffler on
your machine is fitted with this kind of screen.
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.
