EXPLANATION OF COMPONENTS
Battery disconnect switch (1) is used for cutting out the electric-
ity from the battery.
This switch is installed inside the cover on the left side of the
machine.
Raise rubber cover (2), and the switch is seen.
REMARK
Operate this switch while system operating lamp (3) is OFF.
(O): OFF position
Switch key (1) can be pulled out (and inserted) and the current
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 when the controller is
turned ON and goes out in 1 to 7 minutes after the starting
switch is turned to OFF position.
Before operating the battery disconnect switch, check that sys-
tem operating lamp (1) is turned OFF.
NOTICE
If the battery disconnect switch is turned to OFF position
while the system operating lamp is lit, the data in the con-
troller will 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 does not indicate abnormality.
•
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.
