Changing a broken recoil spring

•Lift off the pulley. See instructions under heading Changing a broken or worn starter cord.

•Remove the recoil spring from inside the pulley by tapping the pulley lightly with its inside face downwards against a work bench or the like. If the spring pops out during fitting, wind it up again, working from the outside in towards centre.

•Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring.

Fitting the starter

•To fit the starter, first pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.

•Fit and tighten the screws that hold the starter.

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

•Unnecessary wear to engine parts.

•Excessive fuel consumption.

•Remove the air filter after taking off the air filter cover. When refitting make sure that the air filter seals tightly against the filter holder. Clean the filter by brushing or shaking it.

The filter can be cleaned more thoroughly by washing it in water and detergent.

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.

A HUSQVARNA chain saw can be equipped with different types of air filter according to working conditions, weather, season, etc. Contact your dealer for advice.

Spark plug

The spark plug condition is influenced by:

•Incorrect carburettor adjustment.

•An incorrect fuel mixture (too much or incorrect type of oil).

•A dirty air filter.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check
