Cooling System; Bevel Gear; Air Filter; Cleaning The Air Filter - Husqvarna 135R Manuel D'utilisation

Some mufflers are equipped with a special spark arrestor
screen. If your machine has this type of muffler, you
should clean the screen at least once a week. This is best
done with 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 if necessary
cleaned, monthly. If the screen is damaged it should be
replaced. If the screen is frequently blocked, this can be
a sign that the performance of the catalytic converter is
impaired. Contact your dealer to inspect the muffler. A
blocked screen will cause the machine to overheat and
result in damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
WARNING! Mufflers fitted with catalytic
!
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!

Cooling system

To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Cooling fins on the cylinder.
3 Cylinder cover (directs cold air over the cylinder).
MAINTENANCE
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.

Bevel gear

The bevel gear is filled with the right quantity of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled three-quarters
full with grease. Use HUSQVARNA special grease.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
• Carburettor 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 exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. 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.
