CHECK MONITOR PANEL
1. Turn the starting switch ON.
2. Check that all the monitors, gauges, and the central warn-
ing lamp light up for approx. 3 seconds and the alarm
buzzer sounds for approx. 1 sec.
If the lamps do not light up, there is probably a failure or
disconnection. Contact your Komatsu distributor for inspec-
tion.
CHECK DUST INDICATOR

the maintenance monitor flash, clean the air cleaner ele-
ment.
For details of the method of cleaning, see “CLEANING OR
REPLACING OUTER ELEMENT (4-22)“.
REMARK
A dust indicator is installed inside the engine hood on the left
side of the machine. The dust indicator shows the condition of
clogging of the air cleaner in 5 stages. This makes it possible to
check how clean the element is and when it should be
replaced.
