Installing the Spark Plug
N Screw the spark plug into the
cylinder.
N Connect the spark plug boot (press
it down firmly).
N Fit the carburetor box cover.
For periods of 3 months or longer
N Drain and clean the fuel tank in a
well ventilated area.
N Dispose of fuel properly in
accordance with local
environmental requirements.
N Run the engine until the carburetor
is dry – this helps prevent the
carburetor diaphragms sticking
together.
N Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
N Thoroughly clean the machine – pay
special attention to the cylinder fins
and air filter.
N If you use a biological chain and bar
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
N Store the machine in a dry, high or
locked location, out of the reach of
children and other unauthorized
persons.
N Remove the chain sprocket cover,
chain and guide bar.
N Disengage the chain brake: Pull the
hand guard towards the front
handle.
Replace the chain sprocket:
– after using two saw chains or
sooner
– if the wear marks (arrows) on the
sprocket are deeper than about
0.5 mm (0.02 in) since this would
reduce the life of the chain. You can
use a gauge (special accessory) to
check the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
