Komatsu HB215LC-3, Operation & Maintenance Manual, Page: 187 / 492

The battery disconnect switch (1) is used to cut out the electric-
ity from the battery.
It is located on the right side of the machine.
REMARK
Operate this switch while the system operating lamp (2) is not
lit.
(O): OFF position
The switch key (1) can be pulled out (and inserted) and the cur-
rent from the battery is cut out.
(I): ON position
The current from the battery flows into the circuit.
Before starting the machine, be sure to set the switch to this
position.
SYSTEM OPERATING LAMP
System operating lamp (1) indicates that the controller mount-
ed on the machine is turned on.
System operating lamp (1) lights up in green when the control-
ler is turned on and goes out in 1 to 7minutes after the starting
switch is turned to OFF position.
Before operating the battery disconnect switch, check that sys-
tem operating lamp (1) is not lit.
NOTICE
If the battery disconnect switch is turned to OFF position
while the lamp is lit, the data in the controller may be lost
and system abnormality may occur.
REMARK
• Even if the starting switch is in OFF position, the controller may operate. The lamp lights up in this case, but
it is not a problem.
• After the starting switch has been turned off, the system operating lamp may stay lit for a long time.
In such case, consult your Komatsu distributor.
• The system operating lamp may look slightly luminous in the dark after it is turned off. It is due to the minute
leakage of current and not an abnormal phenomenon.
