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.
Checking the 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.
Changing a broken or worn starter cord
• 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.

MAINTENANCE
Tensioning the recoil spring
• 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.
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.
• Remove the recoil spring by turning the starter over and
loosen the hooks, with the help of a screwdriver. The
hooks hold the return spring assembly on the starter.
• Lubricate the recoil spring with light oil. Fit the pulley and
tension the recoil spring.
