      2. The installation of the hydraulic pump after the air is not discharged will cause bubbles in the hydraulic oil corrosion hydraulic                 components, resulting in poor contact of pump accessories resulting in abnormal pump sound, high pressure pipe jitter phenomenon,   serious will cause components broken pollution of the whole excavator hydraulic system.
