Replacing a broken rewind spring
: Remove the rope rotor.
The bits of spring in the fan housing
might still be under tension and
could fly apart when you take them
out of the housing. To reduce risk of
injury, wear eye and face protection
and work gloves.
: Use a screwdriver to carefully pry
the parts of the spring out of the
housing.
: Lubricate the new spring with a few
drops of non-resinous oil.
: Place the new spring with retaining
frame in position in the fan housing
– the anchor loop must engage the
lug.
: Apply suitable tools (screwdriver,
punch, etc.) to the recesses
(arrows) and push the spring into its
seat – it slips out of the retaining
frame in this process.
If the spring pops out of the housing
during installation: Refit it in the
counterclockwise direction, starting
outside and working inward.
: Reinstall the rope rotor, tension the
rewind spring, fit the fan housing
and secure in position.
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 the carburetor
diaphragms sticking together.
: Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
: Thoroughly clean the unit,
pay special attention to the cylinder
fins and air filter.
: If you use a biological chain and bar

completely fill the chain oil tank.

locked location, out of the reach of
children and other unauthorized
