at a time (max. 5 g) while turning the

points:
N Pull the starter rope only in the 
direction specified.
N Do not pull the rope over the edge of 
the guide bushing.
N Do not pull out the rope more than 
specified.

back, guide it back into the housing 
slowly – see chapter on "Starting /

Have a damaged starter rope replaced 
by your dealer before it breaks 
completely. STIHL recommends that 
you have servicing and repair work 
carried out exclusively by an authorized 
STIHL servicing dealer.
