2. If the gasket is damaged, it cannot be used, and the filter element with damaged filter material or rubber seal.
3. Inferior filter elements cannot be used, because the filtering effect and sealing performance will be relatively poor, and the engine will be damaged after dust enters.
4. If the seal of the inner filter element or the filter material is damaged or deformed, replace it with a new one.
5. It is necessary to check whether there is dust or oil stains on the sealing part of the new filter element, and if so, it needs to be cleaned.
