check the spark arresting screen in
the muffler.
N Wait for the muffler to cool down.
N Loosen the screws (1).

N Remove the spark arresting
screen (3).

To help prolong the wear life of the
starter rope, observe the following
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.
N Do not allow the starter grip to snap
back, guide it back into the housing
slowly – see chapter on "Starting /
Stopping the Engine."
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.
