Brake Oil Temperature Caution Lamp OPERATION The brake oil temperature caution lamp (1) illuminates to warn the operator that the brake oil temperature has increased. When carrying out the check before starting (starting switch at the ON position, engine stopped) The lamp does not illuminate. During operation (engine running) In continuous heavy-duty operations or when traveling long distances downhill where the brake is used frequently, the brake oil temperature increases. The brake oil temperature caution lamp illuminates; the central warning lamp illuminates; and the alarm buzzer sounds intermittently.
At the same time, “E02” is displayed on the top line of the character display and “BRAKE OVERHEAT” on the bottom line. Take the following action. Release the accelerator pedal and move the gearshift lever down one range to reduce the travel speed. Avoid using the brake. Do not keep the brake pedal depressed continuously; use the brake only intermittently. Set the transmission cutoff switch to the ON position when carrying out operations. If use of the brake is reduced for a short time in this manner, the brake oil temperature decreases and the caution lamp goes out.
Torque Converter Oil Temperature Caution Lamp The torque converter oil temperature caution lamp (2) illuminates to warn the operator that the torque converter oil temperature has increased. When carrying out the check before starting (starting switch at the ON position, engine stopped) The lamp does not illuminate. During operation (engine running) If the torque converter oil temperature increases, the torque converter oil temperature caution lamp illuminates. If the oil temperature increases further, the central warning lamp illuminates and the alarm buzzer sounds intermittently.
At the same time, “E02” is displayed on the top line of the character display and “TC OVERHEAT” on the bottom line. Stop the machine and run the engine under no load at a mid-range speed until the lamp goes out. WA430-6 2-19
