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 Let go of the 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 Fit the shroud and secure it with the
lock.
Replacing a broken rewind spring
N Remove the rope rotor.
The bits of spring must 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.
