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
Battery Replacement
Before any electrical service is performed on PDS model
vehicles, the Run-Tow/Maintenance switch must be
placed in the ‘Tow/Maintenance’ position.
If a power wire (battery, motor or controller) is discon-
nected for any reason on the PDS model vehicle, the
Run-Tow/Maintenance switch must be left in the ‘Tow/
Maintenance’ position for at least 30 seconds after the
circuit is restored.
Fig. 23 Preparing Acid Neutralizing Solution
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 explosion that could result in
severe personal injury or death, extreme care
must be used with aerosol containers of battery
terminal protectant. Insulate the metal contain-
er to prevent the metal can from contacting bat-
t e r y t e r m i n a l s w h i c h c o u l d r e s u l t i n a n
explosion.
Use care to connect the battery wires as shown (Ref Fig.
24 on page 21). Tighten the battery post hardware to 90 -
100 in. lbs. (6 - 8 Nm) torque
.
Do not over-torque the ter-
minal stud nut, this will cause a "mushroom" effect on the
battery post which will prevent the terminal nut from
being properly tightened.
Fig. 24 Battery Connections
Prolonged Storage
Battery charger, controller and other electronic devices
need to be disconnected 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
