　　加注过程中，注意检查油位计或油位观察窗，确保油位达到规定范围。

　　During the filling process, pay attention to checking the oil level gauge or oil level observation window to ensure that the oil level reaches the specified range.

　　排气和检查：

　　Exhaust and inspection:

　　启动设备，让液压系统低速运转，排出系统中的空气。

　　Start the equipment, let the hydraulic system run at low speed, and exhaust the air in the system.

　　检查各液压元件和管路是否有泄漏现象。

　　Check for leaks in all hydraulic components and pipelines.

　　确认设备运转正常后，进行必要的调试和测试。

　　After confirming that the equipment is operating normally, perform necessary debugging and testing.

　　二、更换滤芯注意事项

　　2、 Precautions for replacing filter element

　　滤芯型号匹配：

　　Filter element model matching:

　　确保新滤芯的型号、规格与旧滤芯一致，符合设备要求。

　　Ensure that the model and specifications of the new filter element are consistent with those of the old filter element and meet the equipment requirements.

　　安装位置正确：

　　Correct installation position:

　　将新滤芯安装在正确的位置，确保滤芯座和密封垫安装正确、无损坏。

　　Install the new filter element in the correct position, ensuring that the filter seat and gasket are installed correctly and undamaged.

　　操作规范：

　　Operating standards:

　　在更换滤芯过程中，遵循设备制造商的操作规程和规定。

　　During the process of replacing the filter element, follow the operating procedures and safety regulations of the equipment manufacturer.

　　使用合适的工具和设备，避免损坏滤芯和液压系统其他部件。

　　Use appropriate tools and equipment to avoid damaging the filter element and other components of the hydraulic system.

　　检查与测试：

　　Inspection and testing:

　　更换滤芯后，启动设备并进行必要的检查和测试，确保液压系统正常运行。

　　After replacing the filter element, start the equipment and conduct necessary inspections and tests to ensure the normal operation of the hydraulic system.

　　三、其他注意事项

　　3、 Other precautions

　　液压油质量：

　　Hydraulic oil quality:

　　使用高质量的液压油，确保液压系统的性能和稳定性。
