Komatsu — 3.3.2 SIDE INSTRUMENTS

INSTRUMENTS AND CONTROLS 1 - FUEL LEVEL INDICATOR It indicates the fuel level in the tank and functions only when the ignition key is in position « I ». IMPORTANT q If the indicator reaches the red low fuel area during work, stop the machine and provide for refuelling. q The warning light (1) positioned on the front instrument panel signals when the fuel level is too low (see "3.3.1 pos. 1 - LOW FUEL WARNING LIGHT"). 2 - ENGINE COOLANT TEMPERATURE INDICATOR It indicates the engine coolant temperature, which normally must be included between 80°C and 85°C.

If the indicator reaches the red area, indicating that the temperature is too high, the acoustic alarm sends out a continuous signal, the warning light (7) comes on and the general alarm warning light flashes on and off (see "3.3.1 pos. 9 - GENERAL ALARM WARNING LIGHT"). 3 - REVOLUTION COUNTER - HOUR METER This is a combined instrument that indicates the engine speed with a pointer, while the number of operating hours appears in the lower displays. The count is continuous and the hour number is increased by one when the engine has worked for 1 hour, independently on the engine speed. The hour counter keeps counting even if the machine isn’t working or travelling.

The reading must be considered valid for the calculation of the maintenance intervals. 77
