As a kind of construction machinery, the normal operation of Liugong loader plays a vital role in construction efficiency and project quality. As an important part of the loader, the air cleaner is a key factor to ensure that the engine breathes smoothly. So, how often should the air cleaner of the Liugong loader be replaced? When the Liugong loader is working, its engine will constantly draw in air to support the combustion of fuel. The function of the air filter is to filter out dust, sand and other impurities in the air, preventing them from entering the engine and causing wear. However, after a long period of use, the air cleaner will gradually become clogged with these impurities, resulting in poor engine air intake, which in turn affects performance and life. Generally speaking, the air cleaner replacement cycle of LiuGong loaders will be determined according to the harshness of the working environment and the frequency of use. On dusty worksites, the air cleaner should be replaced more frequently. It is generally recommended to check the condition of the air cleaner every 500 hours of work, and replace it if there is significant dust accumulation on the surface of the filter or if the filter material has been deformed or damaged. Of course, this is only a rough replacement cycle recommendation. In practice, the replacement interval should also be decided according to the specific model of the loader and the recommendations in the user manual. In addition, regularly checking the air cleaner and replacing it in a timely manner will not only ensure the normal operation of the engine, but also extend the overall life of the loader. To sum up, the replacement cycle of the air filter element of Liugong loader is not a fixed time, but needs to be judged according to the actual situation. Only by properly replacing the air cleaner can we ensure that the loader can play its maximum efficiency during the construction process.
