Maintenance method
1. When the excavator is working, when the excavator makes abnormal sounds from the pump, the excavator vibrates, or the computer board displays a fault code or alarm, be sure to stop the machine and check whether it is caused by a pump failure.
2. When the operating environment temperature of the excavator is very low, be sure to let the excavator idle for more than 10 minutes after starting. Wait for the excavator temperature to come up before adding load to the excavator to ensure normal operation of the excavator. The hydraulic pump is working properly.
3. When the excavator is operating normally, you must always pay attention to whether the temperature of the excavator's hydraulic oil is too high? Is the excavator water temperature too high?
4. When using the excavator hydraulic pump for the first time, you should pay attention to whether the pump makes abnormal sounds. This is because at the beginning of operation, it is easily affected by air bubbles and dust, poor lubriion at high temperatures, or overload conditions, causing the hydraulic pump to emit abnormal noise. Normal sound.
5. Always pay attention to the value displayed by the excavator hydraulic circuit pressure gauge.
