MAINTENANCE
22 – English
cause fire if directed against dry and combustible
material.
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done
with a wire brush. On mufflers without a catalytic
converter the mesh should be cleaned weekly, or
replaced if necessary. On mufflers fitted with a catalytic
converter the mesh should be checked, and if necessary
cleaned, monthly.
If the mesh is damaged it should be
replaced.
If the mesh 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 mesh will cause the machine to overheat and
result in damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
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).
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
!
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!
