Komatsu — Gauges and Meter

OPERATION DETAILED CONTROLS AND GAUGES Swift Deceleration Display Lamp This monitor (3) informs the operator that the swift deceleration function is being actuated. Actuated: Lights up Canceled: Goes out When the swift deceleration switch is pressed, the swift decel- eration display lamp lights up. When it is pressed again, the lamp goes out. REMARK When the swift deceleration display lamp is lighted up, the engine speed remains at low idling even if the fuel con- trol dial is operated. Gauges and Meter Engine Coolant Temperature Gauge This displays (4) the engine cooling water temperature. During normal operation, the lamp should light up in the green range.

If the lamp in the red range lights up during operation, run the engine at low idling and wait for the temperature to go down to the green range. After starting the engine, warm up it until the green range lights up. Fuel Gauge This shows the fuel level in the fuel tank. During normal opera- tion, the lamp should light up in the green range. If the lamp in the red range flashes during operation, there is less than 13 liters (3.43 US gal) of fuel remaining, so check and add fuel. The correct level may not be displayed for a short time after the starting switch is turned to the ON position, but this is not an abnormality.

Service Meter This meter (6) shows the total operation hours of the machine. Set the periodic maintenance intervals using this display. The service meter advances while the engine is running - even if the machine is not traveling. While the engine is running, operation display (A) at the top inside of the meter will light to show that the meter is advanc- ing. The meter will advance by 1 for each hour of operation regard- less of the engine speed. 3-9
