11. EXPLANATION OF COMPONENTS METER DISPLAY PORTION (A, C, D) (11.1.2) These consist of the meters (speedometer, fuel gauge, engine water temperature gauge, torque converter oil temperature gauge, service meter, transmission shift indicator) and the pilot lamps (turn signal indicator, preheating, front working lamp, rear working lamp, transmission cut-off, parking brake). OPTION DISPLAY PORTION (F) This consists of the monitor lamps and switches for the auto- greasing system. For details of each system or component, see OPTIONS, AT- TACHMENTS.
TESTING ACTUATION OF MACHINE MONITOR SYSTEM When the starting switch is turned to the ON position before starting the engine, all monitor lamps, gauges, and centralized warning lamps will light up for approx. 3 seconds, and the alarm buzzer will sound for approx. 1 second. When this happens, 88 is displayed on the speedometer, and 8 is displayed on the transmission shift indicator. Finally, there will be two beeps to indicate that the monitor check has been completed. If the monitor lamps do not light up, there is probably a failure or disconnection, so please contact your Komatsu distributor for inspection.
When the starting switch is turned to the ON position, if the directional lever is not at the neutral position, the central warning lamp (CAUTION) will flash and the alarm buzzer will sound intermit- tently. If this happens, return the lever to the neutral position, and the lamps will go out and the buzzer will stop. The monitor check cannot be carried out for at least 30 seconds after the engine has been stopped. 2-5
