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
S Completely clean the trimmer.
S Put the trimmer in a building that has good
ventilation.
NOTE: A yearly checkup or tune-up at an
authorized service center will make sure
that the trimmer will provide maximum per-
formance for the next season.
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 gasohol, 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:
S Let the engine run until it is out of gasoline.
S Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
S Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder.
Slowly pull the recoil starter handle so that
the oil will protect the cylinder. Install a new
spark plug in the cylinder.
S Clean dirt and debris from the cylinder
cooling fins and the engine housing.
S If you do not want to remove gasoline, add
a fuel stabilizer to any gasoline left in the
tank. Fuel stalibizer will minimize the
formation of gum deposits and acids. If the
tank is almost empty, mix the fuel stabilizer
with fresh gasoline in a separate container
and add the mixture to the tank. Always
follow the instructions on the stabilizer
container. Run the engine at least ten min-
utes after stabilizer is added to allow the
mixture to reach the carburetor.
