Firstly, connect the oil pump station to the jack using a high-pressure hose equipped with a quick change connector
2: When the quick change connector disengages along the axial direction, first unscrew the outer sleeve, then pull out the male (female) connector along the axial direction and install the dust cap.
3. Determine the center of gravity of the lifting object and select the force point of the separated jack. At the same time, it is necessary to consider the degree of softness and hardness of the ground, whether it is necessary to pad wood, etc., to avoid the risk of tipping during lifting.
4. When the separated hydraulic jack is ready, the pump station can be started, but it can only be loaded after the oil pump station operates normally and reaches its working state. At this point, reverse the handle of the directional valve to the joint connecting the jack chamber A, and the piston rod will extend to achieve the lifting operation; To retract the piston rod, align it with the joint connecting the jack B chamber
