ACAUTION:
Never store the tractor with
3asoline in the tank inside a building
where fumes may reach an open flame or
spark. Allow the engine to cool before stor-
ing in any enclosure.
TRACTOR
Remove mower from tractor for winter
storages. T_is will allow you to clean it thor-
oughly. Remove all dirt, grease, leaves,
etc. Store in a clean, dry area.
• Clean entire tractor (See =CLEANING"
• in the M ajnt_enance- section of this man-
ual).
• Inspect and replace belts, if necessary
(See belt replacement
instructions in the
Service and Adjustments section of this
manual).
• Lubricate as shown in the Maintenance
section of this manual.
• Be sureJha_t all _quts, bolts and screws
are s_:u-_eFy F'a-slened. Inspect moving
parts for damage, breakage and wear.
Replace if necessary.
• Touch up all rusted or chipped paint sur-
faces; sand lightly before painting.
BATTERY
• Fully charge the battery for storage.
• A_ter a period of time in storage, battery
may require recharging.
• To help prevent corrosion and power
leakage during long periods of storage,
battery cables should be disconnected
and battery cleaned thoroughly (see
=TO CLEAN BATI'ERY AND TERMI-
"" NALS" Fn the Maintenar_be section of
this manual).
• After cleaning, leave cal_Ies disconnect-
ed and place cables where they cannot
-
come-in contact with battery terminals.

ENGINE
FUEL SYSTEM
IMPORTANT:
It is important to prevent
gum deposits from forming
in essential
fuel s.ystem-@arts_uch as carburetor, fuel
filter, fu__el'hose, or tank during storage.
Also, experience ind'mates 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 dam-
age the fuel system of an engine while in
storage.
• Drain the fuel tank.
• 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 sta-
bilizer 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 carbure-
tor. Do not drain the gas tank and carbure-
tor 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(S)
• Remove spark plug(s).
• Pour one ounce of oil through spark plug
hole(s) into cylinder(s).
• Turn ignition key to =START" position for
a few seconds to distribute oil.
• Replace with new spark plug(s).
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if it starts to
rust. Rust and/or dirt in your gasoline will
cause problems.
• If possib!e, store your tractor indoors
and cover it to give protection from dust
and dirt.
• Cover your tractor with a suitable protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe, which allows condensation to
form and cause your tractor to rust.
IMPORTANT:
Never cover tractor while
engine and exhaust areas are still warm.
