GENERAL
This procedure contains information and instructions to keep the battery pack in good working order by
inspecting and replacing the electrical connectors, fasteners, graphics, or the entire battery charger
assembly.
INSPECT
Inspect the front panel assembly of the battery pack internal assembly. Check the condition of the Power
Out connector for dents or other damage that would prevent the proper connection of a cable connector.
Check the condition of the Power In cable for cuts or other damage that expose the wiring. When in
operation, ensure that all front panel LED indicators are functional. Ensure that the 3-Position Function
Switch is operational.
WARNING!
Two Person Lift
The Battery Pack weighs approximately 80 pounds (36.3 kg). Two persons must carry the
Battery Pack, lifting with legs, not back, to prevent injury.
REPLACE
To replace the internal battery charger (1), remove batteries as detailed in WP 0031 and loosen the two
hex nuts (2) at the base of the threaded shafts (3) just behind the charger assembly. Remove the two
shafts (3) (it is not necessary to remove rear shafts), making sure not to drop the nuts and washers under
the battery pack base plate that secure the shafts to the frame. Remove the 6 retaining screws and
washers (4) that secure the battery charger (1) to the battery pack frame (5). Remove the defective
charger assembly.
Install a new charger (1) in place on the battery pack frame (5). Secure in place with the 6 retaining
screws and washers (4). Install two threaded shafts (3) removed earlier and secure.
Reinstall the batteries and battery pack cover as described in WP 0031.
