If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor properly
adjusted, the cause may be in the
muffler.
: Have the muffler checked for
contamination (coking).
STIHL recommends that all
maintenance and repair work be carried
out by an authorized STIHL dealer.
To help prolong the wear life of the
starter rope, observe the following
points:
: Pull the starter rope only in the
direction specified.
: Do not pull the rope over the edge of
the guide bushing.
: Do not pull out the rope more than
specified since it might break.
: Do not let the starter grip snap back,
guide it slowly into the housing.
See also chapter “Starting /
Stopping the Engine”!
Replace a damaged starter rope in
good time or have it replaced by your
STIHL dealer!
For periods of about 3 months or longer:
: Drain and clean the fuel tank in a
well ventilated area.
: Dispose of remaining fuel and
cleaning solution properly in
accordance with local
environmental requirements.
: Run engine until carburetor is dry –
this helps prevent carburetor
diaphragms sticking together.
: Thoroughly clean the machine – pay
special attention to the cylinder fins
and air filter.
: Store the machine in a dry, high or
locked location – out of the reach of
children and other unauthorized
persons.
