Some mufflers are fitted with a catalytic converter. See

“Technical data” to see whether your machine is fitted with a
catalytic converter.
The cooling system consists
of:
The muffler is designed to
dampen the noise level and
to direct the exhaust fumes
away from the user. The
exhaust fumes are hot and
can contain sparks, which
can result in fire if the

inflammable material. Some
mufflers are equipped with a
special spark arrest screen. If
your machine is fitted with
this type of screen it should
be cleaned regularly. This is
done using 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 cleaned monthly. If the
screen is damaged it should
be replaced. If the screen is
frequently blocked, this can
be a sign that the function
of the catalytic converter is
impaired. Contact your
dealer to inspect the muffler.
A blocked screen will cause
the engine to overheat
Spark plug
The condition of the spark
plug is affected by:
•
•
An incorrect carburetor
setting.
An incorrect fuel
mixture (too much or
faulty oil).
0,5 mm
•
A dirty air filter.
resulting in damage to the
cylinder and piston. Also see
under “Maintenance”.
These factors cause
deposits on the spark plug
electrode that may result in
malfunction or starting
difficulties.
NOTE!
Never use a machine with a defective muffler.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
!
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping.This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
changed after about one month of operation or earlier if
necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.
