Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
above top of plates.
Cleaning Batteries
To reduce the possibility of dam-
age to vehicle or floor, neutralize
acid before rinsing batteries.
To reduce possible damage to electrical components
while cleaning, do not use pressure washer to clean
batteries.
Cleaning should take place per Periodic Service Sched-
ule (Ref. GENERAL INFORMATION & ROUTINE MAIN-
TENANCE).
When cleaning the outside of the batteries and terminals,
do not use a water hose without first spraying with a solu-
tion of sodium bicarbonate (baking soda) and water to
neutralize any acid deposits.
Use of a water hose without first neutralizing any acid,
will move acid from the top of the batteries to another
area of the vehicle or storage facility where it will attack
the metal structure or the concrete/asphalt floor. After
hosing down the batteries, a residue will be left on the
batteries which is conductive and will contribute to the
discharge of the batteries.
To prevent battery damage, be
sure that all battery caps are
tightly installed.
The correct cleaning technique is to spray the top and
sides of the batteries with a solution of sodium bicarbon-
ate (baking soda) and water. This solution is best applied
with a quart sized hand sprayer. The solution should con-
sist of 2 teaspoons (10 ml) of sodium bicarbonate (bak-
ing soda) mixed with 1 quart (1 liter) of clear water (Ref
Fig. 4 on page H-3). In addition to the batteries, special
attention should be paid to metallic components adjacent
to the batteries which should also be sprayed with the
sodium bicarbonate (baking soda) solution.
Allow the solution to sit for at least three minutes; use a
soft bristle brush or cloth to wipe the tops of the batteries
in order to remove any residue that could cause the self
discharge of the battery. Rinse the entire area with low
pressure clear water. All of the items required for com-
plete battery cleaning and watering are contained in the
Battery Maintenance Kit (P/N 25587-G01).
Battery Replacement
Before any electrical service is
performed on 48 volt48 volt
model vehicles, the Run-Tow/Maintenance switch
must be placed in the ‘Tow/Maintenance’ position.
If a power wire (battery, motor or controller) is dis-
connected for any reason on the 48 volt model vehi-
cle, the Run-Tow/Maintenance switch must be left in
the ‘Tow/Maintenance’ position for at least 30 sec-
onds after the circuit is restored.
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-
