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):
1The 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.
2The 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.
IMPORTANT INFORMATION Poor maintenance of the air filter will cause carbon
Starter
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.
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.
