Installing the spark plug
N Install the spark plug and connect
the spark plug boot (press it down
firmly) – reassembly all other parts
in the reverse sequence.
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor is properly
adjusted, the cause may be the muffler.
Have the muffler checked for
contamination (carbonization) by your
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
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.
