starter grip and straighten it out.
– Hold the starter grip firmly to keep
the rope tensioned.
– Let go of the rope rotor and
slowly release the starter grip so
that the rope winds itself onto the
rotor.
The rewind spring is correctly
tensioned when the starter grip sits
firmly in the rope guide bushing
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.
