As a kind of heavy machinery and equipment, the use of hydraulic oil is a very critical indicator in the daily use and maintenance of Liugong loader. The normal range of the hydraulic oil scale plays a vital role in ensuring the proper operation of the loader and extending its service life. So, how much is the hydraulic oil scale of Liugong loader? It mainly depends on the specific model of the loader and the use environment. Generally speaking, the oil level of the hydraulic oil should be between the lowest and highest scale of the scale to ensure the normal operation of the hydraulic system. If the oil level is too low, it may cause the hydraulic system to be evacuated, which will affect the normal operation of the loader, while if the oil level is too high, it may increase the operating resistance of the system or even cause the oil temperature to be too high. When using Liugong loaders, it is recommended that the operator regularly check the oil level of the hydraulic oil and adjust it in time when the oil level is abnormal. In addition, attention should be paid to changing the hydraulic oil regularly to maintain its good lubrication and cooling properties. In conclusion, understanding the normal range of the hydraulic oil scale of Liugong loaders, and doing a good job of daily inspection and maintenance of hydraulic oil, is the key to ensure the normal operation of the loader and extend its service life.
