If the oil pollution is serious, it needs to be replaced in advance. When replacing the filter element, it is necessary to check whether there are metal particles or debris at the bottom of the filter element. If there are copper or iron filings, it indicates that some components in the hydraulic system, such as pump thunder and valves, have been damaged or will be damaged. If there are rubber impurities, it indicates that the seals in the hydraulic cylinder have been damaged and need to be replaced or cleaned together with the filter element.
