NOTE!
To maintain as low opera-
ting temperature as possible
the engine is equipped with
a cooling system.
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

mufflers are equipped with a
special spark arrest screen. If
your machine is fitted with

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

the catalytic converter is
impaired. Contact your
dealer to inspect the muffler.

cylinder and piston. Also see
under “Maintenance”.

on the spark plug electrode
that may result in
malfunction or starting
difficulties.

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 machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
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.
