The starter grip must be drawn firmly
into the rope guide bush. If it tips
sideways: increase the spring tension by
another turn.
It must be possible to turn the rope rotor
on another half-turn when the rope has
been drawn out completely. If not, the
spring has been tensioned too tightly
and may break!
N Remove one turn of the rope from
the rotor
N Mount the fan housing on the
crankcase
N Move the Master Control lever to the
stop position 0
N Press the remaining rope into the
handle until the nippel (6) is flush
with the handle

If the spring has popped out: refit it –
working counterclockwise – from the
outside inwards
N Screw in screws (1) again
N Reinstall the rope rotor, tension the
rewind spring, replace the fan
housing and screw it into place
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.
The broken pieces of spring may
still be under tension and can
spring apart unexpectedly on
removal from the fan housing –
risk of injury! Wear a face shield
and protective gloves.
