Komatsu WA600-8, Operation & Maintenance Manual, Page: 208 / 554

The system operating lamp indicates that the controller mount-
ed on the machine is turned on.
System operating lamp lights up in green when the controller is
turned on and goes out in 5 to 6 minutes after the power for the
machine is turned off.
Before operating the battery disconnect switch, check that sys-
tem operating lamp is not lit.
REMARK
• Even if the starting switch is in OFF position, the controller
may operate. The system operating lamp lights up at this
time, but it is not a failure.
• After the starting switch has been turned to OFF position,
the system operating lamp may stay lit for a long time.
In such case, consult your Komatsu distributor.
