MAINTENANCE
Air filter
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. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.
2 The paper filter is accessible under cover B. This filter
must be replaced/cleaned when the engine's power
drops. 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.
Starter
Changing a broken or worn starter cord
• Loosen the filter and cylinder cover.
• Loosen the screws that hold the starter against the
crankcase and remove the starter.
• Pull out the cord approx. 30 cm and hook it into the notch
in the rim of the pulley. Release the recoil spring by letting
the pulley rotate slowly backwards.

IMPORTANT INFORMATION Poor maintenance of the air
filter will cause carbon build-up on the spark plug and
abnormal wear to engine parts.
!
WARNING! When the recoil spring is wound
up in the starter housing it is under tension
and can, if handled carelessly, pop out and
cause personal injury.
Always be careful when changing the recoil
spring or the starter cord. Always wear
protective goggles.
