OPERATION
CHECK CENTRAL WARNING LAMP
Carry out the following checks to prevent failure by the warning
system due to defective operation of the buzzer or blown lamp bulb
in central warning lamp (1). If any abnormality is found, ask
Komatsu distributor for inspection.
Stop the engine, turn the starting switch to the ON position, set
the parking brake valve lever to the PARKING position, move
the shift lever to any position other than N, and check. If the lamp
flashes and buzzer sounds, it is normal.
If the air pressure is below the specified pressure, the lamp
should flash and the buzzer should sound when the starting
switch is turned ON.
CHECK BRAKING EFFECT
Check if the braking capacity of the parking brake, foot brake, and retarder brake.
If any abnormality is found, ask Komatsu distributor to repair.
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.
