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.
Also, experience
indicates
that 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.
1. Drain the fuel tank.
2.
Start the engine 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
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 drain 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).
CYUNDER
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.
BA'VrERY
Disconnect the battery from the engine
connector and charge battery 48 hours.
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 give protection
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.
A CAUTION:
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.
