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. A blocked screen will cause the engine to
overheat and may lead to serious damage.

Note! The screen must be replaced if it is damaged. If the
screen is blocked the machine will overheat and this will
cause damage to the cylinder and piston. Never use a
machine with a muffler that is in poor condition. Never use a
muffler if the spark arrestor screen is missing or

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.

A muffler equipped with a catalytic converter significantly
reduces the amount of hydrocarbons (HC), nitrogen oxides
(NO) and aldehydes in the exhaust fumes. Carbon monoxide
(CO), which is poisonous and odorless, is not however
reduced! Consequently, never work in an enclosed or badly
ventilated area. Good air circulation should always prevail
when working in snowy hollows, ravines or in confined
conditions.
