Storing the Machine

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
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
: Store the unit in a dry and high or
locked location, out of the reach of
children and other unauthorized
persons.
Checking and Replacing
Chain Sprocket
: Remove the chain sprocket cover,
chain and guide bar.
: Disengage the chain brake:
Pull hand guard toward the front
handle.
Replace the chain sprocket:
– after using two Oilomatic chains
– or sooner if the wear marks (arrows)
on the sprocket are deeper than
approx. 0.5 mm since this would
reduce the life of the chain.
You can use a gauge ("Special
Accessories") to check the depth of
the wear marks on sprockets.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
