SERVICE AND ADJUSTMENT
STORAGE
WARNING: Do not remove gaso-
line while Inside a building, near
a fire, or while you smoke. Gaso-
line fumes can cause an explo-
sion or a fire.
When the trimmer is put in storage for thirty
days or more, follow the steps below to
make sure the trimmer is in good condition
the following season.
Trimmer
Completely clean the trimmer.
Put the trimmer in a building that has good
ventilation.
NOTE: A yearly checkup or tune-up at a
Craftsman authorized service center will
make sure that the trimmer will provide
maximum performance for the next sea-
son.
Engine
IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts
such as the carburetor, fuel filter, fuel hose,
and tank during storage. Also, using alco-
hol-blended fuels (called gaeohol, ethanol
or methanol) can attract moisture which
leads to separation and formation of acids
during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To prevent engine damage when the trimmer
is in storage for 30 days or more, follow the
steps below:
Let the engine run until it is out of gasoline.
'o
Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
Remove the spark plug from the cylinder,
Pour one ounce of oil into the cylinder.
Slowly pull the recoil starter handle so that
the oilwill protect the cylinder. Install a new
spark plug in the cylinder.
Clean dirt and debris from the cylinder
cooling fins and the engine housing.
If you do not want to remove gasoline, add
a fuel stabilizer, such as Craftsman fuel
stabilizer No. 33500, to any gasoline left in
the tank. Craftsman fuel stalibizer will
minimize the formation of gum deposits
and acids. If the tank is almost empty, mix
Craftsman fuel stabilizer with fresh gaso-
line in a separate container and add the
mixture to the tank. Always follow the in-
structions on the stabilizer container. Run
the engine at least ten minutes after stabi-
lizer is added to allow the mixture to reach
the carburetor.
Battery
Charge the battery for 16-24 hours before
storage and again before use each season.
