MAINTENANCE

•Undo the bolt in the centre of the pulley and remove the drive disc, drive disc spring and the pulley. Insert and secure a new starter cord in the starter pulley. Wind approx. 3 turns of the starter cord on the starter pulley. Fit the starter pulley so that the end of the recoil spring hooks into the starter pulley. Now assemble the drive disc spring, drive disc and the bolt in the centre of the pulley. Carry the starter cord through the hole in the starter housing and the starter handle. Tie a good knot on the starter cord.

Tensioning the recoil spring

•Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise.

Note! Check that the pulley can be turned an additional 1/ 2 turn when the starter cord is pulled all the way out.

Replacement of broken recoil and drive disc springs

Recoil spring (A)

•Lift up the starter pulley. See instructions under the heading Changing a broken or worn starter cord. Remember that the recoil spring is coiled under tension in the starter housing.

•Remove the cassette with the recoil spring from the starter.

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

Drive disc spring (B)

•Undo the bolt in the centre of the pulley and remove the drive disc and the drive disc spring.

•Replace the drive disc spring and fit the drive disc above the 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 JONSERED chain saw can be equipped with different types of air filter according to working conditions, weather, season, etc. Contact your dealer for advice.
