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 letting 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 storage
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 carburetor.
Do not
empty
the gas tank and carburetor
if using
fuel stabilizer.
ENGINE
OIL

and replace
with clean engine oil.

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

• If possible,
store your unit indoors
and
cover it to protect
it from dust and dirt.
• Cover your unit with a suitable
protec-
tive 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.
ACAUTION:
Never store the lawn mower
with gasoline
in the tank inside a building
where
fumes
may reach
