MAINTENANCE

Starter

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 (12 inches) 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 center 
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.

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

Changing a broken recoil spring

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.

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.

!

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.

Care must be exercised when replacing the 
return spring or the starter cord. Wear 
protective glasses and protective gloves.
