CAUTION! Some mufflers are fitted with a catalytic
converter.See chapter on Technical data to see whether your
machine is fitted with a catalytic converter.

The muffler is designed to reduce the noise level and to direct
the exhaust gases away from the operator. The exhaust
gases are hot and can contain sparks, which may cause fire
if directed against dry and combustible material.
Some mufflers are equipped with a special spark arrestor
screen. If your machine has this type of muffler, you should
clean the screen at least once a week.This is best done with
a wire brush.

On mufflers without a catalytic converter the screen should be
cleaned weekly, or replaced if necessary. On mufflers fitted
with a catalytic converter the screen should be checked, and
if necessary cleaned, monthly. If the screen is damaged it
should be replaced.

Air intake on the starter.
Fins on the flywheel.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
If the screen is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired. Contact
your dealer to inspect the muffler.A blocked screen will cause
the machine to overheat and result in damage to the cylinder
and piston.
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Air filter
CAUTION! Never use a machine with a defective muffler.
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
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!
