OPERATION Engine Coolant Temperature Gauge The engine coolant temperature gauge (2) shows the engine coolant temperature. During normal operations, the indicator should be in the white range (A). If the indicator enters the red range (B) during operations, caution lamp (C) inside the engine coolant temperature gauge lights up. At the same time, the central warning lamp lights up and the alarm buzzer sounds; “E02” is displayed on the top line of the character display and “ENGINE OVERHEAT” on the bottom line. Run the engine under no load at a mid-range speed and wait until the indicator returns to the white range (A).
Hydraulic Temperature Gauge The hydraulic temperature gauge (3) shows the hydraulic oil temperature. During normal operations, the indicator should be in the white range (A). If it enters the red range (B) during operations, caution lamp (C) inside the hydraulic oil temperature gauge will light up. At the same time, the central warning lamp lights up and the alarm buzzer sounds intermittently. In addition, “E02” is displayed on the top line of the character display and “HYD OVERHEAT” on the bottom line. Run the engine under no load at a mid-range speed and wait until the indicator returns to the white range (A).
Fuel Gauge The fuel gauge (4) indicates the amount of fuel remaining in the fuel tank. F position: Tank is full. E position: Fuel level is low. When the amount of remaining fuel goes below 35 l (9.25 gal), the caution lamp (A) inside the fuel gauge illuminates. If the caution lamp illuminates, check the fuel level and add fuel. 2-30 WA430-6
