9—STORAGE
9.1—GENERAL INSTRUCTIONS
When you do not plan to use your vehicle for
some time, it should be stored in a dry and protected
place. Unnecessary exposure to the elements may
deteriorate its appearance and shorten the usual service
life.
9.2—ENGINE
1. Drain the fuel from the fuel tank and carburetor.
2. Operate the engine until the gasoline in the
carburetor is completely consumed.
Gum will eventually form in the tank, fuel
line, and carburetor if the fuel is not
drained. Gum in the carburetor jets and
passage affects engine starting.
3. While the engine is still warm, drain the oil from the
crankcase and refill with fresh oil. Refer to the
engine manual for specific instructions.
4. After engine has cooled, remove the spark plugs
and put about one tablespoon of SAE 30 oil into the
cylinder.
5. Clean exterior of engine. Paint the exposed metal or
coat it with a light coating of rust preventative oil.
9.3—BATTERY
1. Remove battery and clean it, refer to Manufacturer’s
manual for specific instructions. Also refer to 8.3
and 8.4 in the Maintenance Section of this manual.
2. Maintenance-free batteries should be stored in an
upright position in a cool, dry place. Storage above
80° F (26.7°C) greatly increases self-discharge. If
wet batteries are discharged, the electrolyte will
freeze when stored below 20° F(-7° C).
The battery should be checked every 60
to 90 days while in storage, and should
be recharged if necessary.
9.4—TRACTOR
Wash, clean and completely lubricate the
tractor. Paint exposed metal with National Mower paint.
9.5—TIRES
1. Before storing the vehicle, clean the tires
thoroughly.
2. Jack up the vehicle so that the load is off the tires.
If it is not jacked up, check the tires at regular
intervals and re-inflate as necessary to keep them
at the recommended pressure.
3. Store the vehicle so that tires are protected from
the sunlight.
9.6—STARTING THE ENGINE
AFTER STORAGE
1. Check and recharge the battery according to
recommendations given by battery manufacturer.
a.Refer to Section 8.3 in this manual.
b.Reinstall the battery.
2. Check oil level in crankcase and hydraulic oil tank.
3. Fill the fuel tank with fresh gasoline. Check fuel
filter.
4. Remove the spark plug and wipe dry. Crank the
engine (with spark plug removed), using starter,
until excess oil has been expelled through the
spark plug hole. Replace the plug and connect the
ignition lead wires.
5. Before driving the vehicle, check to make certain
that the tires are properly inflated to the proper
pressure.
6. Either move the vehicle outside before starting
engine or keep doors and/or windows wide open to
provide sufficient ventilation to prevent danger from
carbon monoxide gas in the exhaust. Start the
engine but do not operate at high speed
immediately after starting. Allow time for it to
become properly warmed and lubricated.
