MAINTENANCE

Starter

Changing a broken or worn starter cord

Loosen the screws that hold the starter against the 
crankcase and remove the starter.

Pull the cord out about 30 cm and lift it into the cut-out in 
the periphery of the starter pulley. When the cord is intact: 
Release the spring tension by letting the pulley rotate 
slowly backwards.

Remove any remnants of the old starter cord and check that 
the return spring works. Insert the new starter cord through 
the hole in the starter housing and in the cord pulley. 

Secure the starter cord around the cord pulley as illustrated. 
Tighten the fastening well and ensure that the free end is as 
short as possible. Secure the end of the starter cord in the 
starter handle.

Guide the cord through the cut-out in the periphery of the 
pulley and wind the cord 3 times clockwise around the centre 
of the starter pulley.

Now pull the starter handle and in doing so tension the spring. 
Repeat the procedure once more, but this time with four turns.

Note that the starter handle is drawn to its correct home 
position after tensioning the spring.

Check that the spring is not drawn to its end position by 
pulling out the starter line fully. Slow the starter pulley with 
your thumb and check that you can turn the pulley at least a 
further half turn.

Tensioning the recoil spring

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

Changing a broken recoil spring

Undo the bolt in the centre of the pulley and remove the 
pulley.

Bear in mind that the return spring lies tensioned in the 
starter housing.

Loosen the bolts holding the spring cassette.

!

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.
