Komatsu — 11.1.1 WARNING DISPLAYS

OPERATION 11.1.1 WARNING DISPLAYS 1. CENTRAL CHECK LAMP WARNING If this monitor flashes, perform an inspection and maintenance of the appropriate location as soon as possible. If any abnormality is found in the CHECK items before starting the engine (engine oil level, engine water level), the monitor lamp for abnormal location will flash and the central CHECK lamp will also flash. Check the location where the monitor lamp is flashing and perform the check before starting. When performing the checks before starting, do not rely on just the monitor. Always carry out the specified maintenance items.

If the engine oil level is abnormal before starting the engine, the engine oil level will change after starting the engine. Thus, the central CHECK lamp and monitor lamp will stop flashing. An abnormal engine water level will cause the central CHECK lamp to flash and the alarm buzzer to sound intermittently after starting the engine. If any abnormality in the charging system exists 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. WA450-3MC 2-6
