3.2 Explanation of components Operation 1. 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 dis- tances downhill where the brake is used frequently, the axle oil temperature becomes high, so the axle oil temperature caution lamp and central warning lamp light up and the alarm buzzer sounds intermittently.
GK032097 At the same time, “E02“ and “BRAKE OVERHEAT“ are dis- played on the character display in turn, so take the following action. 1. Release the accelerator pedal and move the speed range selector switch down one range to reduce the travel speed. 2. Avoid using the brake. 3. Do not keep the brake pedal depressed continuously; use the brake only intermittently. If use of the brake is reduced for a short time in the way recom- mended above, the axle oil temperature will go down and the caution lamp will go out. 2. Parking brake reminder caution lamp This lamp (2) lights up when engine is stopped but the parking brake is not applied.
At the same time, the central warning lamp lights up and the alarm buzzer sounds intermittently. When the parking brake is applied, the lamp goes out and the buzzer stops. GK032098 3. HST oil temperature caution lamp This lamp (3) lights up to warn the operator that the HST oil tem- perature 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) When the HST oil temperature goes up, the HST oil temperature caution lamp and central warning lamp light up, and the alarm buzzer sounds intermittently.
GK032099 At the same time, “E02“ and “HST OVERHEAT“ are displayed on the character display in turn, so stop the machine and run the engine at a midrange speed under no load until the lamp goes out. 3-18 WA150-5H – VEAM934100
