Checking the Spark Plug
N
Clean dirty spark plug.
N
Check electrode gap (A) and
readjust if necessary – see
"Specifications".
N
Rectify the problems which have
caused fouling of the spark plug.
Possible causes are:
–
Too much oil in fuel mix.
–
Dirty air filter.
–
Unfavorable running conditions.
WARNING
Arcing may occur if the adapter nut (1) is
loose or missing. Working in an easily
combustible or explosive atmosphere
may cause a fire or an explosion. This
can result result in serious injuries or
damage to property.
N
Use resistor type spark plugs with a
properly tightened adapter nut.
Installing the Spark Plug
N
Screw the spark plug into the
cylinder.
N
Connect the spark plug boot (press
it down firmly).
For periods of 3 months or longer
N
Drain and clean the fuel tank in a
well ventilated area.
N
Dispose of fuel properly in
accordance with local
environmental requirements.
N
Run the engine until the carburetor
is dry – this helps prevent the
carburetor diaphragms sticking
together.
N
Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
N
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.
