The introduction of gauges & controls needed for operating the machine is below. Be sure to
understand their functions and methods for use.
1.2.1 Vehicle Gauges and Lights
z Engine Water Temperature Gauge
This gauge indicates the temperature of engine water.
When the temperature index lies in the green ranges (60 ~100 ), ℃℃
the water temperature is normal.
Notice:
If the temperature index moves past green into the red range, be sure
to stop the machine for inspection.
Refer to 3.4.2 Steps to Stop Engine in this chapter for details of
stopping the engine. The below is the same.
z Torque Converter Oil Temperature Gauge
This gauge shows the torque converter oil temperature
When the temperature index lies in the green range (60 ~120 ), the ℃℃
oil temperature is normal. If the temperature index moves past green into
the red ranges, be sure to stop the machine for inspection.
z Working Chronometer
This indicator shows the total operation hours of the machine; its
value can be used as a reference for inspection and maintenance.
z Gearbox Oil Pressure Gauge
This gauge indicates the pressure of the gear-shifting system.
If the pressure index lies in the green range(1.5MPa~1.7MPa), the
oil pressure is normal. Be sure to stop the machine for inspection
if the index moves outside this range.
If the pressure index lies in the range of (15~17)×100kPa or
(21.75~24.65) ×10PSI, the oil pressure is normal. Be sure to stop
the machine for inspection if the index moves outside this range.
