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 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).
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly a few times
to distribute oil.
4. Replace with new spark plug.
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 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 an open
flame or spark. Allow the engine to cool
before storing in any enclosure.
