7, for several jack at the same time lifting, in addition to the jack should be placed correctly, you should use more top diversion valve, and each jack load should be balanced, pay attention to keep lifting speed synchronization. Consideration must also be given to the possibility of subsidence of the ground due to uneven weight, preventing the weight from tilting and becoming dangerous.
8, the first manual pump quick connector and the top butt, and then select the location, the oil drain screw on the pump tightened, you can work.
