Komatsu — 11.1 MACHINE MONITOR

11. EXPLANATION OF COMPONENTS If there is any abnormality in the battery charging system when the engine is running, the battery charge caution pilot lamp will flash and the central CHECK lamp will also flash at the same time. If the lamps flash, check the charging circuit. 2. CENTRAL CAUTION LAMP (CAUTION) WARNING If these monitor lamps flash, stop the engine immediately or run it at low idling and do as follows.

If there is an abnormality in any CAUTION item when the engine is running (engine water temperature, torque converter oil tem- perature, engine water level, brake oil pressure, engine oil pressure), the alarm buzzer will sound intermittently and the monitor lamp for the location of the abnormality will flash and the central CAUTION lamp will also flash. If the fuel gauge enters the red range when the engine is running, the fuel gauge will flash and the central CAUTION lamp will also flash. If they flash, check the fuel level and add fuel. 3. ENGINE WATER LEVEL CAUTION LAMP This warns the operator that the coolant level in the radiator has dropped.

When carrying out the checks before starting (main switch ON, engine stopped): If the level of the coolant in the radiator is low, the caution pilot lamp and central CHECK lamp will flash. If the monitor lamps flash, check the coolant level in the radiator and add water. When operating (engine running): If the condition is normal, the caution pilot lamp should be off. If the level of the coolant in the radiator is too low, the warning pilot lamp and central CAUTION lamp will flash, and the alarm buzzer will sound intermittently. If the monitor lamps flash, stop the engine, check the level of the coolant in the radiator and add water.

Stop the machine on level ground before carrying out this check. 2-7
