6. MAINTENANCE
Refer to the basic PDM Manual No. 901356 for all
general service information. Refer to
Figure 1 for the
location and identification of items not listed in the
basic manual.
6.1. Battery Part Number 003216
These Gel Cell Batteries are maintenance-free. Any
attempt to open the battery will void the warranty.
Ultra-deep discharging of brand new batteries should
be avoided for at least 15 cycles. To dramatically
extend battery life, ultra-deep discharge should be
avoided. The shallower the average discharge, the
longer the battery life.
6.1.1. Charging Batteries
Charging requirements will vary depending on depth of
discharge and temperature. Follow safety rules when
placing a battery on charge.
Proceed as follows:
1. Park truck at charging station with platform low-
ered and key switch off.
2. Check the condition of the AC cord, the battery
connector and battery cables. If there are any cuts
in the cable, any exposed wires, loose plugs or
connectors, DO NOT attempt to charge the batter-
ies. Contact appropriate personnel for repairs to
be made.
3. Disconnect the batteries from the truck and con-
nect batteries to the charger. Make sure connec-
tors are mated properly.
4. Connect the AC cord to the truck and then plug
into the 120 Volt AC power supply.
5. The battery charger is fully automatic and will
cycle automatically (depending on amount of
charge needed). Charge status can be observed
as follows (Refer to
Figure 2 ):
a. The top three LED’s indicate charger status.
At start of charge the RED (Charge) LED will
be ON indicating the batteries are connected
and charging. After the batteries charge to
approximately 80% the Yellow LED comes
ON. After a time (1 hour minimum) the Green
LED comes ON indicating battery ready.
NOTE: The battery charger includes an
override timer which terminates the
charge if the cycle does not complete
after 18 hours of charging. This time-
out condition is indicated by the
green LED flashing off and on, and it
indicates a fault condition which
should be investigated. This will
occur if the charger cannot raise the
battery voltage to the preset voltage
limit. Possible causes indicate a bat-
tery fault, a charger fault, low AC
power supply voltage, or excessive
discharge. The override timer can be
reset by switching the AC power to
the charger off.
b. The lower four red LED’s indicate current flow.
Normally at start of charge, if the batteries are
discharged, all four red LEDs will be on indi-
cating maximum 25A charge current. As the
batteries charge the current drops and the
LEDs go OFF as the current drops to 20A,
15A, 10A and 5A respectively.
