Tensioning the rewind spring
N Make a loop in the starter rope and
use it to turn the rope rotor six full
revolutions in the direction of the
arrow.
N Hold the rotor steady. Pull out and
straighten the twisted rope.
N Release the rope rotor.
N Release the rope slowly so that it
winds onto the rotor.
The starter grip must sit firmly in the rope
bushing. If the grip droops to one side:
Add one more turn on the rope rotor to
increase spring tension.
When the starter rope is fully
extended it must still be possible
to rotate the rotor another half
turn. If this is not the case, the
spring is overtensioned and could
break:

N Take one turn of the rope off the
rotor.
Models with Easy2Start:
N Fit the spring housing, driver and
washer on the starter post.
N Use circlip pliers to carefully install
the circlip in the starter post groove.
All versions
N Fit the fan housing on the
crankcase.
N Install the shroud – see "Shroud".
Replacing a broken rewind spring
N Removing the rope rotor
The bits of spring might still be
under tension and could fly apart
when you take them out of the
housing. To reduce the risk of
injury, wear face protection and
work gloves.
N Carefully remove the parts of the
spring.
N Lubricate the new spring with a few
drops of non-resinous oil.
N Place the new spring with frame in
position in the fan housing – the
anchor loop must engage the lug in
the housing.
N Apply suitable tools (screwdriver,
punch, etc.) to the recesses and
push the spring into its seat in the
fan housing – it slips out of the
frame in this process.
N Take the frame out of the fan
housing.
N
Reinstall the rope rotor, tension the
rewind spring, fit the fan housing
and secure it in position.
