WARNING
The bits of spring might still be under
tension and could fly apart when you
take them out of the housing. To reduce
the risk of injury, wear face protection
and work gloves.
N Carefully remove the parts of the
spring.
N Lubricate the new spring with a few
drops of non-resinous oil.
N Place the new spring with frame in
position in the fan housing – the
anchor loop must engage the lug in
the housing.
N Apply suitable tools (screwdriver,
punch, etc.) to the recesses and
push the spring into its seat in the
fan housing – it slips out of the frame
in this process.
N Take the frame out of the fan
housing.
N Secure spring with screw.
N Refit the rope rope, tension the
rewind spring and fit the fan housing
on the engine housing.
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 Disengage the chain brake: Pull the
hand guard toward the front handle.
N Remove the chain sprocket cover,
chain and guide bar.
Replace the chain sprocket
– after using two saw chains or
sooner
– if the wear marks (arrows) on the
sprocket are deeper than about
0.02 in (0.5 mm) 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.
