If Battery Is Discharged - Komatsu D31EX -22 Operation & Maintenance Manual

OPERATION

IF BATTERY IS DISCHARGED

It is dangerous to charge the battery when it is mounted on the machine.
Always remove it before charging it.
Always stop the engine and turn the starting switch to the OFF position
before inspecting or removing the battery.
During the charging operation, hydrogen gas is generated inside the
battery, so there is danger of explosion. Do not smoke or bring any
flame close to the battery, and be careful not to cause sparks.
Battery electrolyte (dilute sulphuric acid) will attack your clothes and
skin. If battery electrolyte gets on your clothes or skin, immediately
wash it off with large amounts of fresh water.
If battery electrolyte gets into your eyes, immediately wash your eyes
with fresh water. After that, get medical attention immediately.
Always wear protective glasses and rubber gloves when handling the
battery.
When removing the battery terminals, disconnect the ground terminal
(normally the negative (-) terminal) first. When installing, install the
positive (+) terminal first.
It is extremely dangerous if any tool forms a contact between the
positive (+) terminal and the chassis. This will cause sparks.
If the terminals are loose, improper contact will cause sparks, and there
is danger that the flammable gas generated inside the battery will ignite
and cause an explosion.
When installing, tighten the battery terminals securely.
When removing or installing, always check which is the positive (+)
terminal and which is the negative (-) terminal.
