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

English
WARNING
The bits of spring must still be under
tension and could fly apart when you
take them out of the housing. To reduce
the risk of injury, wear face protection
and work gloves.
Use a screwdriver to carefully
N
remove the parts of the spring from
the housing.
Lubricate the new spring with a few
N
drops of non-resinous oil.
Place the new spring with retaining
N
frame in position in the fan housing
– the anchor loop must engage the
lug in the housing.
Apply suitable tools (screwdriver,
N
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
N
rewind spring, fit the fan housing
and secure it in position.

Storing the Machine

For periods of 3 months or longer
Drain and clean the fuel tank in a
N
well ventilated area.
Dispose of fuel properly in
N
accordance with local
environmental requirements.
Run the engine until the carburetor
N
is dry – this helps prevent the
carburetor diaphragms sticking
together.
Remove the saw chain and guide
N
bar, clean them and spray with
corrosion inhibiting oil.
Thoroughly clean the machine – pay
N
special attention to the cylinder fins
and air filter.
If you use a biological chain and bar
N
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
Store the machine in a dry, high or
N
locked location, out of the reach of
children and other unauthorized
persons.

Checking the Chain Sprocket

Disengage the chain brake: Pull the
N
hand guard toward the front handle.
Remove the chain sprocket cover,
N
chain and guide bar.
Replace the chain sprocket
after using two saw 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 accessory) to check
the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
