Cooling system

To maintain as low an
operating temperature as
possible the engine is
equipped with a cooling
system.
The cooling system consists
of:
1. An air intake on the
starter unit.
2. Cooling fins on the
flywheel.
3. Cooling fins on the
cylinder
4. Cylinder cover (leads cold
air onto the cylinder).
Clean the cooling system using a brush at least once a week, in
difficult conditions more often.
A dirty or blocked cooling system leads to the engine over-
heating resulting in damage to the cylinder and piston.

Air filter

The air filter should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel
consumption
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter
cover and remove the air
filter. Wash in clean, warm
soapy water. Ensure that the
filter is dry before refitting.
An air filter used for a long
period of time can never be
cleaned completely. There-
fore it is necessary to replace
the filter from time to time
with a new filter. A dam-
aged air filter must always
be replaced.

Angle gear

The angle gear is filled with
a sufficient quantity of
grease at the factory.
However, before using the
machine you should check
that the angle gear is filled
to 3/4 with grease. Use
Husqvarna special grease.
Normally, the grease does
not need to be changed
except when the angle gear
is repaired.

Spark plug

The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel mixture
(too much or faulty oil).
• A dirty air filter.
These factors cause deposits
on the spark plug electrode
that may result in malfunc-
tion or starting difficulties.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0,6–0,7 mm. The spark plug should
be changed after about one month of operation or earlier if
necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.
0,6-0,7 mm
