Storing The Machine; Checking And Replacing Chain Sprocket - Stihl MS 192 T Instruction Manual

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
: Disengage the chain brake:
Pull hand guard toward the
handlebar.
: Remove chain sprocket cover,
chain and guide bar.
Replace the chain sprocket:
– after using two Oilomatic chains or
sooner
– if the wear marks (arrow) on the
sprocket are deeper than approx.
0.5 mm since this would reduce the
life of the chain. Use a gauge
(special accessory) to check the
depth of the wear marks.
It is best to use two chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
Removing
: Pull off the spark plug boot (1) and
unscrew the spark plug (2).
: Push the locking strip (3) – narrow
end first – into the cylinder and then
turn it 180°.
: Rotate clutch clockwise as far as
stop.
