Starter

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.
