Engine Coolant Temperature Gauge
Illustration 1 g00664915
Engine Coolant Temperature Gauge - The engine coolant temperature gauge shows the temperature of the engine coolant. If the pointer in the gauge enters the red zone, the coolant temperature is too high. The red zone indicates that the temperature of the coolant is 108°C (225°F) or more. If the coolant temperature is too high, reduce the load on the engine. If the temperature does not return to the normal range, stop the machine until the cause of the overheating has been corrected. Engine Oil Pressure Gauge

Engine Oil Pressure Gauge - The engine oil pressure gauge indicates the engine oil pressure. The pressure reading will be greatest after starting a cold engine. While the engine idles, the engine oil pressure will decrease as the engine warms up. As the engine speed is increased to full load, the engine oil pressure will increase. The engine oil pressure will stabilize. Fuel Level Gauge

Fuel Level Gauge - The fuel gauge indicates the amount of fuel that remains in the fuel tank. Hydraulic Oil Temperature Gauge
Illustration 4 g00664916
Hydraulic Oil Temperature Gauge - The hydraulic oil temperature gauge indicates the temperature of the hydraulic oil. If the pointer in the gauge indicates that the temperature of the oil is more than 88°C (190°F), reduce the load on the machine. If the temperature does not return to the normal range, stop the machine until the cause of the overheating is corrected. The warning light comes on and the horn sounds at a hydraulic temperature of 108 °C (226 °F).
