Spark Plug; Air Filter - Husqvarna 125R Operator's Manual

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 wilt cause the machh_e to
overheat and result in damage to the cylin-
der and piston.

CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.
I_ib ARNING:
Mufflers fitted with
catalytic converters get very hot
during use and remain so for some
time after stopping. This also ap-
plies at idle speed, Contact can re-
sult in burns to the skin. Remember
the risk of fire!
_lb WARNING:
The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.
_lb WARNING:
Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where 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 indoors or near com-
bustible material!
Spark plug
I
The spark plug condition is h_fluenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or in-
correct type of oil).
• 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
ptug can damage the piston/cylinder.
Air filter
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
• Carburetor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts
• Excessive fuel consumption
Clean the filter every 25 hours, or more
regularly if conditions are exceptionafly
dusty.
Cleaning the air filter
Remove the air filter cover and take out the
filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals. A damaged air
filter must always be replaced.
