Adjust the idle speed using the T screw. When an adjustment 
is necessary, first turn the screw clockwise until the blade 
starts to rotate. Now turn the screw anti-clockwise until the 
blade stops rotating.

Rec. idle speed: 2700 rpm

•

The fuel filter sits inside the fuel tank.

•

The fuel tank must be protected from contamination when 
filling. This reduces the risk of operating disturbances 
caused by blockage of the fuel filter located inside the 
tank.

•

The filter cannot be cleaned but must be replaced with a 
new filter when it is clogged. The filter should be 
changed at least once per year.

Air filters 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.

The air filter system consists of an oiled foam plastic filter (1) 
and a paper filter (2):

1

The foam plastic filter is easily accessible under the filter 
cover A. This filter should be checked weekly and 
replaced if necessary.

In order to obtain a good filtering effect, the filter must be 
replaced regularly or cleaned and oiled. A special 
HUSQVARNA oil has been produced for this purpose.

Remove the foam plastic filter. Wash the filter well in tepid 
soapy water. After cleaning, rinse the filter well in clean 
water. Squeeze out and allow the filter to dry. NOTE! High 
pressure compressed air can damage the foam.

Put the filter in a plastic bag and pour the filter oil over it. 
Knead the plastic bag to distribute the oil. Squeeze the 
excess oil out of the filter inside the plastic bag and pour 
off the excess before fitting the filter to the machine.  
CAUTION! Never use common engine oil

The paper filter is accessible under cover B. This filter 
must be replaced/cleaned when the engine's power drops 
or each month. The filter is cleaned by shaking. Note that 
the filter must not be washed. NOTE! High pressure 
compressed air can damage the filter.

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.

Poor maintenance of the air filter will cause carbon build-up 
on the spark plug and abnormal wear to engine parts.
