MAINTENANCE
If the mesh is frequently blocked, this can
be a sign that the performance of the cata-
lytic converter is impaired. Contact your
servicing dealer to inspect the muffler. A
blocked mesh will cause the machine to
overheat and result in damage to the cylin-
der and piston.
Muffler bolts
CAUTION! Never use a machine that has
a faulty or loose muf fler. Ensure the muffler
bolts are tight.
Spark arrestor mesh
WARNING: Mufflers fitted with
catalytic converters get very hot
during use and remain so for some
time afte r stopping. This also ap-
plies at idle speed. Contact can re-
sult in burns to the skin. Remember
theriskoffire!
W ARNING: Theinsideofthe
muffler contain chemicals that may
be carcinoge nic. Avoid contac t with
these elements in the event of a
damaged muffler .
W ARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxid e, which can ca use
carbon monox ide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exh aust fume s from the engine
are hot and may contain sparks
which can start a fire. Never start
the machin e indoors or near com-
bustible material!
Spark pl u g
The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much or in-
correct type of oil).
S A dirty air filter.
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action.
If the spark plug is dirty, clean it and check
that the electrode gap is 0.024 inch (0.6
mm). The spark plug should be replaced
after about a month in operation or earlier if
necessary.
0.024 inch (0.6 mm)
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
Muffler
CAUTION! Muffler is fitted with a catalytic
converter designed to reduce harmful ex-
haust gases.
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 com-
bustible material.
Mufflers are equipped with a special spark
arrestor mesh. The mesh should be
checked and, if necessary. cleaned by a
servicing dealer. If the mesh is damaged,
it should be replaced.
