OPERATION

EXPLANATION OF COMPONENTS

The following is an explanation of devices needed for operating the machine.
To perform suitable operations correctly and safely, it is important to completely understand methods of operating
the equipment, and the meanings of the displays.

MACHINE MONITOR

A: User code display
B: Caution items
C: Emergency stop item
NOTICE
When the starting switch is turned to the ON position before the engine is started, all the monitors, gauges, and the central
warning lamp will light up for approx. 3 seconds, and the alarm buzzer will sound for approx. one second. When this happens, the
speedometer will display 88.
If no monitor lamp lights up, then there is probably a failure or disconnection in that circuit, therefore contact your Komatsu
distributor to have the circuit checked.
When the starting switch is at the ON position, if the shift lever is not at the neutral position, then the transmission shift lever
position pilot lamp (1) and the central warning lamp will flash and the alarm buzzer will continue to sound intermittently. At this
time, when the lever is placed in neutral, letter N is displayed, the central warning lamp goes out and the buzzer stops.
Checking for blown caution lamp or pilot lamp bulbs
Turn the starting switch to the ON position before starting the engine, press bulb check switch (2) and check that
no caution lamp or pilot lamp bulbs are blown.
If any lamp does not light up, the bulb is probably blown, so replace the bulb.
If the lamp does not light up even when the bulb is replaced, there is probably a failure or disconnection, so please
contact your Komatsu distributor to have the circuit checked.
D: Meter display portion
E: Mechatronic caution lamp portion
