Grip on fan housing
- Hold the starter grip firmly to
keep the rope tensioned.
- Let go of the rope rotor and
slowly release the starter grip.
Note: The rewind spring is correctly
tensioned when the starter grip sits
firmly in the rope guide bush without
drooping to one side. If this is not the
case, tension the spring by one
additional turn.
When the starter rope is fully
extended, it must still be possible to
rotate the rope rotor at least another
half turn before maximum spring
tension is reached. If this is not the
case, pull the rope out, hold the rope
rotor steady and take off one turn of
the rope.
Do not overtension the rewind
spring as this will cause it to
break.
- Refit the fan housing.
6.6 Replacing the Starter
Rope Guide Bush
Rope guide bush
The wear on the guide bush is
accelerated by the starter rope being
pulled sideways. The wall of the guide
bush eventually wears through,
becomes loose and has to be
replaced.
- Remove the fan housing.
- Remove the rope rotor, see 6.2,
take off the starter grip and pull out
the rope.
- Use a screwdriver to pry the old
bush out of the fan housing.
Installing the new rope bush:
- Place the new bush in its seat in
the fan housing.
- Insert the screw spindle of the
installing tool through the bush
from inside the housing.
- Fit the thrust sleeve, tapered end
first, and the hexagon nut.
