SECTION A. INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
GENERAL
These instructions include the technical information of the
Lithium ION system, which is one of the power system
configurations on JLG Compact Crawler Booms (CCB).
NOTICE
READ THESE INSTRUCTIONS AND OPERATION MAINTENANCE OF THE
MACHINE CAREFULLY.
• IN CASE OF CELL FAILURE, DO NOT OPEN THE BAT-
TERY COMPARTMENT.
• IF THE BATTERY COMPARTMENT TEMPERATURE IS
HIGH, OPEN THE BATTERY COMPARTMENT CARE-
FULLY TO COOL THE CELLS. WAIT UNTIL THE COM-
PA R T M E N T I S C O O L E D D O W N TO A M B I E N T
TEMPERATURE.
• DO NOT OPEN THE BATTERY COMPARTMENT IF THE
TEMPERATURE IN THE COMPARTMENT IS TOO HIGH.
THERE IS A RISK OF EXPLOSION OR EXPOSURE TO
HAZARDOUS SUBSTANCES.
• WEAR APPROPRIATE PROTECTIVE EQUIPMENT ON
HANDS, FEET, EYES AND BODY WHILE WORKING ON
BATTERIES MAINTENANCE AND BATTERY COMPART-
MENT.
NOTICE
USE CLASS D FIRE EXTINGUISHER IN CASE OF FIRE HAZARD.

INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
The CCB using Gasoline, Diesel or Lithium ION batteries
have the same structure, functionality and the same
hydraulic, electrical and electronic systems.
The CCB with dual power configuration, Gasoline/Diesel
and electrical motor, are coupled with two tandem
pumps, while those with the Lithium ION, have only one
tandem pump, driven by an electrical motor which
receives power through the Lithium ION battery pack.
The Lithium ION Battery pack integrates a system to con-
trol the RPM of the electrical motor, to supply sufficient
amount of oil flow to the hydraulic system, to recharge the
batteries, and to keep all components functional.
The Lithium ION Battery pack system is controlled by a
device called Battery Management System (BMS). All com-
ponent or functions are activated by the BMS. At the start
of the machine, the 12 volts Lead-acid Battery switch ON
the BMS through the ECM1-2. If there is no fault, the BMS
gets supply from Lithium ION Battery pack.
