The moisture and air and the acidic substances generated after oxidation will rust the metal. And corrosion, affecting the normal operation of the hydraulic system.

The hydraulic oil replacement method that makes the excavator reborn
The traditional method of replacing the hydraulic oil of an excavator is nothing more than drawing out the hydraulic oil in the hydraulic oil tank, replacing the hydraulic oil filter element, and refilling the new hydraulic oil. This method can only replace 48% of the hydraulic oil in the system. When 52% of the dirty oil remaining in the system is mixed with the new hydraulic oil, the service life of the hydraulic pump and other components is greatly reduced.
