Immediate!y- prepare your tractor for stor-
age at the end of the season or if the trac-
tor will not be used for 30 days or more.
_CAUTION:; Never store the tractor with
gasoline 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
storage. This will allow you to clean it thor-
oughly. Remove all dirt, grease, leaves,
-etc. Store in a clean, dryarea.
• Clean entire tractor (See =CLEANING" in
the Maintenance section of this manual).
• 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 sure that all nuts, bolts and screws
are securely fastened. Inspect moving
parts for damage, breakage and wear.
Replace if necessary.
• Touci,Pl_ all rested or chipped paint sur-
faces;'sand lightly before painting.
BATTERY
• Fully charge the battery for storage.
• After 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 BATTERY AND TERMINALS" in
the Maintenance section of this manual).
• After cleaning, leave cables disconnect-
ed and place cables where they cannot
come in contact with battery terminals.
• If battery is removed from tractor for
storage, do not store battery directly on
concrete or damp surfaces.
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 i[Lstorage.
