Repair instructions
7.2 Changing a broken or worn starter
cord
When the starter cord is worn and must be replaced,
the tension on the return spring must be released.
1
Pull the cord out about 30 cm and lift it into the notch
on the outside of the starter pulley. Release the
tension on the return spring by allowing the starter
pulley to rotate slowly backwards (see gure 2).
7.3 Tensioning the recoil spring
1
Fasten the starter cord in the notch in the pulley
rim and wind the pulley about 3 turns clockwise.
Check that the pulley is free to rotate at least an-
other half turn when the starter cord is fully exten-
ded (see gure 4).
2
Tension the cord with the handle. Remove the
thumb and released back the cord (see gure 5).
WARNING!
If the spring tension is activated
on the starter pulley, the spring
can fly out and cause personal
injury. Wear protective glasses.
2
Undo the bolt in the centre of the pulley and re-
move the pulley (see gure 3).
3
Fit a new cord through the hole in the pulley and tie
a knot to secure it. Feed the other end of the cord
through the hole in the starter housing and through
the starter handle, then tie a double knot in the
end. Wind about 3 turns of the starter cord onto the
pulley. Fit the bolt through the centre of the pulley
and tighten to a torque of 2–3 Nm.
Cleaning and inspection
Clean and inspect all parts carefully. If there
are any cracks or other defects replace the
damaged parts with new ones. Lubricate the
return spring with a little grease.
