If Battery Is Discharged - Komatsu Galeo BR380JG-1 Operation & Maintenance Manual

OPERATION

IF BATTERY IS DISCHARGED

Do not charge the battery when the battery is installed on the machine.
This is dangerous.
Before inspecting or handling the battery, stop the engine and turn the
key in the starting switch to the OFF position.
Batteries generate hydrogen gas, so there is danger of explosion.
Never smoke or bring any flame close to the battery. Also be careful not
to cause any spark.
The battery electrolyte is dilute sulphuric acid, and it will attack your
clothes or skin. If you get any battery electrolyte on your clothes or
skin, wash it off immediately with large amounts of fresh water.
If it gets into your eyes, wash immediately with fresh water, then consult
a doctor for treatment.
When handling the battery, wear protective glasses and rubber gloves.
When removing the battery, remove the ground side (normally the
negative (-) terminal) first. When installing the battery, install the
positive (+) terminal first.
If any tool touches between the positive terminal and the chassis, it will
cause a spark. This is dangerous, so be careful not to allow this to
happen.
If the terminal is loose, there is danger that defective contact may
generate a spark and cause an explosion.
When connecting the terminal, be sure to tighten it securely.
When removing or installing the battery, be sure to confirm the positive
(+) terminal and negative (-) terminal.
REMOVE AND INSTALL BATTERY
Before removing the battery, remove the ground cable (normally connected to the negative (-) terminal).
If any tool touches between the positive terminal and the chassis, there is a hazard of sparks being generated.
When installing the battery, connect the ground cable last.
When replacing the battery, secure it with battery hold-down.

PRECAUTIONS FOR CHARGING BATTERY
If the battery is charged improperly, it may explode. Accordingly,
charge it according to "IF BATTERY IS DISCHARGED (PAGE
3-135)" and the instruction manual attached to the charger, and
observe the following items.
Set the voltage of the charger to match the voltage of the battery
to be charged. If the correct voltage is not selected, the charger
may overheat and cause an explosion.

positive (+) terminal of the battery, then connect the negative (-)
charger clip of the charger to the negative (-) terminal of the
battery. Be sure to attach the clips securely.
