Maintenance, Service, and Repair
Batteries
Page 6
Explosive mixtures of Hydrogen gas are
present within battery cells at all times. Do
not work with or charge battery in an area
where open flames (including gas furnace
or water heater pilots), sparks, cigarettes,
or any other sources of combustion are
present. Always provide ample ventilation
in rooms where batteries are being charged.
Failure to do so may result in severe bodily
injury and/or property damage.
Battery electrolyte will stain and corrode
most surfaces. Immediately and thoroughly
clean any surface outside of the battery
that the battery electrolyte comes in
contact with. Failure to clean may result in
property damage.
1. Make sure the key-switch is in the “OFF”
position, then remove the key.
2. Place the forward-reverse switch in the
center “OFF” position.
3. Set the park brake.
4. Place blocks under the front wheels to
prevent vehicle movement.
5. Disconnect the main positive and
negative cables at the batteries.
REPLACING (6-VOLT BATTERIES ONLY)
Note: If the batteries are over one year old, it is
recommended to replace them as a set.
6. Thoroughly clean the batteries and battery
compartment. Refer to
Cleaning
in this section
for information regarding cleaning the batteries.
7. Remove the battery hold downs.
8. Inspect the battery hold downs for corrosion. If any
signs of corrosion are seen then the battery hold
downs should be replaced.
9. Remove all battery jumpers from both posts of the
battery or batteries being replaced.
Note: It is recommended to replace the battery
jumpers when replacing the batteries.
10. Remove the batteries from the vehicle.
11. Inspect the battery compartment for signs of
corrosion.
12. If minimal signs of corrosion are seen, then the
damaged paint should be stripped off and the
entire battery compartment prepped and repainted.
13. If there are excessive signs of corrosion, then
it may be necessary to replace some of the
frame members or completely rebuild the battery
compartment.
14. Inspect the main positive and negative cables and
terminals, charger cables and terminals and 12-volt
tap wiring. If any of the terminals or wires show
signs of corrosion, then they must be repaired or
replaced.
Do not leave cables on batteries that have
been removed from the vehicle. Cables
left on batteries could cause a short circuit
resulting in battery explosion, severe bodily
injury and/or property damage.
A battery is a live electrical source. It
cannot be disconnected or neutralized. Do
not drop any tool or conductive object onto
the battery. A conductive object that comes
in contact with the battery terminals will
initiate a short circuit of the battery. This
could cause the battery to explode resulting
in severe bodily injury and/or property
damage.
Battery electrolyte is poisonous and
dangerous. It contains sulfuric acid. Avoid
contact with skin eyes or clothing. Wear
rubber gloves and safety glasses while
servicing batteries. DO NOT INGEST! This
may result in severe bodily injury.
