Do not use a spark plug with a
detachable SAE adapter terminal (3).

combustible fumes and cause a fire.

damage to property.
N Only use resistor type spark plugs
with solid, non-threaded terminals
Installing the Spark Plug
N Screw the spark plug into the
cylinder.
N Press the spark plug boot firmly
onto the spark plug.
N Fit the cap (1) on the shroud from
the rear and push the lug (2) into the

screw (4) firmly.
If engine running behavior is still
unsatisfactory after servicing the air filter
and adjusting the throttle cable, the
cause may be the muffler.
Have the muffler checked by a servicing
dealer for contamination
(carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.

approx. 3 months or more
N Drain and clean the fuel tank in a
well ventilated place

the regulations and having regard
for the environment

is dry. This helps to prevent the
carburetor diaphragms sticking
together.

cutting attachment. Treat metal
cutting attachments with protective
oil.

place, out of the reach of children
