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 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 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.

Loosen the bolts holding the spring cassette.

Remove the recoil spring by tapping the starter, with the 
inside facing downwards, gently on a work bench. If the 
spring pops out during assembly, coil it up from the 
outside, working inwards.

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.

!

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.
