: 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.

: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.

: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 machine, pay special attention to the cylinder fins and air filter.

:If you use a biological chain and bar lubricant, e.g. STIHL BioPlus, completely fill the chain oil tank.

:Store the machine in a dry and high or locked location, out of the reach of children and other unauthorized persons.
