ENGINE
FUEL
SYSTEM
IMPORTANT:
It is important
to prevent
gum deposits
from forming
in essential
fuel system
parts such as carburetor,
fuel
filter, fuel hose, or tank during
storage.
Alcohol
blended
fuels (called
gasohol
or
using 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.
• Empty
the fuel tank by starting
the en-
gine and let it run until the fuel lines and
carburetor
are empty.
• Never use engine
or carburetor
cleaner
products
in the fuel tank or permanent
damage
may occur.
• Use fresh fuel next season.
NOTE:
Fuel stabilizer
is an acceptable
alternative
in minimizing
the formation
of
fuel gum deposits
during
storage.
Add
stabilizer
to gasoline
in fuel tank or stor-
age container.
Always
follow the mix ratio
found on stabilizer
container.
Run engine
at least 10 minutes
after adding stabilizer
to allow the stabilizer
to reach the car-
buretor.
Do not empty
the gas tank and
carburetor
if using fuel stabilizer.
ENGINE
OIL
Drain oil (with engine
warm)
and replace
with clean engine
oil.
(See "ENGINE"
in
the Maintenance
section
of this manual).

OTHER
• Do not store gasoline
from one season
to another.
• Replace
your gasoline
can if your can
starts
to rust.
Rust and/or
dirt in your
gasoline
will cause
problems.
• If possible,
store your unit indoors
and
cover it to protect
it from dust and dirt.
• Cover your unit with a suitable
protective
cover that does not retain
moisture.
Do
not use plastic.
Plastic
cannot
breathe,
which
allows
condensation
to form and
will cause your unit to rust.
IMPORTANT:
Never cover mower
while
engine
and exhaust
areas are still warm.
_I_CAUTION:
Never store the lawn mower
with gasoline
in the tank inside
a building
where
fumes

or spark.
Allow the engine
