. OPERATION EXPLANATION OF COMPONENTS CAUTION ITEMS CAUTION (1) (2) (3) Axle oil temperature caution lamp Torque converter oil temperature caution lamp Engine coolant temperature caution lamp (4) (5) Hydraulic oil temperature caution lamp Fuel level caution lamp AXLE OIL TEMPERATURE CAUTION LAMP This lamp (1) lights up to warn the operator that the brake oil temperature has risen. During checks before starting (when the starting switch is turned to the ON position but the engine is not started), this monitor does not light up.

During operation (engine running) In continuous heavy-duty operations or when traveling long distances downhill where the brake is used frequently, the axle oil temperature becomes high. The axle oil temperature caution lamp and central warning lamp light up and the alarm buzzer sounds intermittently. At the same time, the top line of the character display displays "E02" and the bottom line displays "BRAKE OVERHEAT", so take the following action. 1. Release the accelerator pedal and move the gearshift lever down one range to reduce the travel speed. 2. Avoid using the brake. 1) Do not keep the brake pedal depressed continuously; use the brake only intermittently.

2) When using the left brake pedal, turn the transmission cut-off switch ON to carry out operations. If use of the brake is reduced for a short time in the way recommended above, the axle oil temperature will go down and the caution lamp will go out. 3 - 17 If these lamps light up, sto p operations q uickly and car ry out the followi
