OPERATION
CHECK MACHINE MONITOR SYSTEM
1. Before starting the engine, turn the starting switch to the ON position.
2. Check that all monitor lamps, gauges, and the central warning lamp light up for approx. 3 seconds and that the
alarm buzzer sounds for approx. 1 second.
REMARK
When this is done, the speedometer should display 88.
When the starting switch is turned to the ON position, the pilot lamp at the transmission shift lever position will
flash if the shift lever is not at the N position. When the shift lever is moved to the N position, N is displayed.
After the engine is stopped, the monitor cannot be checked until at least 30 seconds have passed.
3. When checking the monitor, check for blown bulbs in the the
caution lamps and pilot lamps at the same time. Before starting
the engine, turn the starting switch to the ON position, press
bulb check switch (1), and check that no caution lamp or pilot
lamp bulb is blown.
If the monitor lamp, caution lamp, or pilot lamp do not light up,
there is probably a failure or disconnection, therefore contact
your Komatsu distributor for inspection.
CHECK BRAKING CAPACITY OF SECONDARY BRAKE
WARNING
If the machine moves, it will lead to the serious human injury. If the machine starts to move while checking the braking capacity,
lower the engine speed and set the shift lever to N position. Then set the parking brake lever to PARKING position.
Check the braking capacity of the secondary brake as follows.
1. Set the air pressure to the maximum, stop the machine on level
ground, place the parking brake valve lever at TRAVEL, and
move secondary brake lever (1) to the APPLIED position.
2. Set gear shift lever (2) to the D position, gradually raise the
engine speed, and check that the machine does not move
even when the engine reaches full speed. If the machine does
not move, it is normal.
3. Lower the engine speed and set the shift lever to N position.
Set parking brake valve lever to PARKING position.
