Owner’s Manual and Service Guide
Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
Remove battery hold downs and cables. Lift out batteries
with a commercially available lifting device.
If the batteries have been cleaned and any acid in the
battery rack area neutralized as recommended, no corro-
sion to the battery racks or surrounding area should be
present. Any corrosion found should be immediately
removed with a putty knife and a wire brush. The area
should be washed with a solution of sodium bicarbonate
(baking soda) and water and thoroughly dried before
priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and
the battery hold downs tightened to 45 - 55 in. lbs. (5 - 6
Nm) torque, to prevent movement but not tight enough to
cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from
the battery terminals or the wire terminals with a solution
of sodium bicarbonate (baking soda) and brush clean if
required.
To prevent battery explo-
sion that could result in
severe personal injury or
death, extreme care must be used with aerosol con-
tainers of battery terminal protectant. Insulate the
metal container to prevent the metal can from con-
tacting battery terminals which could result in an
explosion.
Use care to connect the battery wires as shown (Ref. Fig.
31 on page 23). Tighten the battery post hardware to 50 -
70 in. lbs. (6 - 8 Nm) torque
.
Protect the battery terminals
and battery wire terminals with a commercially available
protective coating.
Prolonged Storage
Battery charger, controller and other
electronic devices need to be discon-
nected since they will contribute to the premature discharge of
batteries.
During periods of storage, the batteries will need atten-
tion to keep them maintained and prevent discharge.
In high temperatures the chemical reaction is faster,
while low temperatures cause the chemical reaction to
slow down. A vehicle that is stored at 90° F (32° C) will
lose .002 of specific gravity each day. If a fully charged
battery has a specific gravity of 1.275, and the battery is
allowed to sit unused, it will become partially discharged.
When it reaches 1.240, which it will do in less than
twenty days, it should be recharged. If a battery is left in
a discharged state, sulfating takes place on and within
the plates. This condition is not reversible and will cause
permanent damage to the battery. In order to prevent
damage, the battery should be recharged. A hydrometer
