Muffler; Spark Plug - Husqvarna 124L Manuel D'utilisation

WARNING:
If the idle speed can-
not be adjusted so that the cutting
attachment stops, contact your ser-
vicing dealer. Do not use the ma-
chine until it has been correctly ad-
justed or repaired.
Unit/Maintenance Safety
Disconnect the spark plug before perform-
ing maintenance, except carburetor adjust-
ments.

Muffler

CAUTION! Muffler is fitted with a catalytic
converter designed to reduce exhaust gas
emissions.
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. If the mesh is fre-
quently blocked, this can be a sign that the
performance of the catalytic 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 cylinder and piston.

CAUTION! Never use a machine that has

bolts are tight.

lytic converters get very hot during use
and remain so for some time after stop-
ping. This also applies at idle speed. Con-
tact can result in burns to the skin. Re-
member the risk of fire!
WARNING:

be carcinogenic. Avoid contact
with these elements in the event of
a damaged muffler.
WARNING:

which can cause carbon monoxide
poisoning. DO NOT start or run the
machine indoors, or anywhere that
is poorly ventilated. The exhaust
fumes from the engine are hot and
may contain sparks which can start
a fire. Never start the machine in-
doors or near combustible material!

Spark plug

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" (0.6 mm). The spark plug should be
replaced after about a month in operation or
earlier if necessary.
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
