MAINTENANCE

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 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.

Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley.

Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the centre of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of 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.

CAUTION! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out.

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.

Clean the air filter daily, or more often in demanding conditions.

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.
