Muffler
WARNING! Never use the machine
!
indoors or in spaces lacking proper
ventilation. Exhaust fumes contain
carbon monoxide, an odourless,
poisonous and highly dangerous gas.
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.

GENERAL SAFETY PRECAUTIONS
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.
WARNING! Mufflers fitted with catalytic
!
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!
WARNING! The inside of the muffler
!
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
