For periods of 3 months or longer
► Drain and clean the fuel tank in a well ventila‐
ted area.
► Dispose of fuel properly in accordance with
local environmental requirements.
► Run the engine until the carburetor is dry – this
helps prevent the carburetor diaphragms stick‐
ing 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, high or locked
location, out of the reach of children and other
unauthorized persons.

28.1 Fit new chain sprocket
– after use of two saw chains or earlier
– if the wear marks (arrows) are deeper than
0.5 mm – otherwise the service life of the saw
chain is reduced – use check gauge (special
accessory) to test
Using two saw chains in alternation helps pre‐
serve the chain sprocket.
STIHL recommends use of original STIHL chain
sprockets in order to ensure optimal functioning
of the chain brake.
