Replacing a broken rewind spring
: Lubricate the new spring with a few 
drops of non-resinous oil. 
: Remove the rope rotor as described 
in “Replacing the starter rope”.
: Remove parts of old spring.
: Fit new spring housing – bottom 
plate must face downward. Engage 
outer spring loop over the lug.
: Refit the rope rotor.
Go to “Tensioning rewind spring”.
If the spring pops out and uncoils 
during installation: Refit it in the 
spring housing in the counter-
clockwise direction – start outside 
and work inward.
Tensioning rewind spring
: Make a loop in the unwound starter 
rope and use it to turn the rope rotor 
six full revolutions in the direction of 
the arrow (see illustration).
: Hold the rotor steady – straighten 
the twisted rope.
: Release the rotor and let go of rope 
slowly so that it winds onto the rotor. 
The starter grip must sit firmly in the 
rope guide bushing. If the grip 
droops to one side: Increase spring 
tension by one additional turn.
