CHARGING THE BATTERY
Test and, if necessary, recharge the battery after the
tractor has been stored for a period of time.
• A voltmeter or load tester should read 12.6 volts
(DC) or higher across the battery terminals.
• Charge the battery with a 12-volt battery charger
at a MAXIMUM rate of 10 amps.
BATTERY MAINTENANCE
The battery is filled with battery acid and then sealed
at the factory. However, even a “maintenance free”
battery requires some maintenance to ensure its
proper life cycle.
• Spray the terminals and exposed wire with a
battery terminal sealer, or coat the terminals with
a thin coat of grease or petroleum jelly, to protect
against corrosion.
• Always keep the battery cables and terminals
clean and free of corrosion.
• Avoid tipping. Even a sealed battery will leak
electrolyte when tipped.
BATTERY STORAGE
• When storing the tractor for extended periods,
disconnect the negative battery cable. It is not
necessary to remove the battery.
• All batteries discharge during storage. Keep the
exterior of the battery clean, especially the top. A
dirty battery will discharge more rapidly.
• The battery must be stored with a full charge. A
discharged battery can freeze sooner than a
charged battery. A fully charged battery will store
longer in cold temperatures than hot.
• Recharge the battery before returning to service.
Although the tractor may start, the engine charging
system may not fully recharge the battery.
SERVICING ELECTRICAL SYSTEM
A fuse is installed to protect the tractor’s electrical
system from damage caused by excessive amper-
age. Always use the same capacity fuse for
replacement. If the electrical system does not func-
tion, check for a blown fuse. See Figure 22
If you have a recurring problem with blown fuses,
have the tractor’s electrical system checked by your
White Outdoor dealer.
Figure 22
Relays and Switches
There are several safety switches in the electrical
system. If a function of the safety interlock system
described earlier is not functioning properly, have the
electrical system checked by your White Outdoor
dealer.
LUBRICATION
• Using a pressure lubricating gun, lubricate the
front castor axles and pivot axle with a No. 2
multi-purpose grease after every 10 hours of
service.
• Refer to the "MOWER DECK" section later in this
manual for deck lubrication procedures.
• Periodically lubricate all other pivot points with a
quality lubricating oil.
TIRE MAINTENANCE
Check the tire air pressure after every 50 hours of
operation or weekly. Keep the tires inflated to the
recommended pressures. Improper inflation will
shorten the service life of a tire. See the tire side wall
for proper inflation pressures. Observe the following
guidelines:
• Do not inflate a tire above the maximum pressure
shown on the sidewall of the tire.
• Do not reinflate a tire that has been run flat or
seriously under inflated. Have a qualified tire
mechanic inspect and service the tire.
