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.
use a mufﬂer if the spark arrestor screen is missing
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
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.
