Popular Long Stroke Double Acting Hydraulic Piston Cylinder

If the oil in the pump body is insufficient, it is necessary to add working oil to the pump before it can work. Estimate the weight, and avoid overloading. Select the jack's focus point to ensure that the center of gravity of the lifting object is perpendicular to the top surface of the jack. At the same time, it is necessary to consider whether the ground is soft and hard and whether it is padded with tough wood, so as to avoid the danger of tipping during lifting.
After the jack lifts the heavy object, the heavy object should be supported with tough wood in time. It is forbidden to use the jack as a support. If there is no special device, it is forbidden to use several jacks at the same time, so as to avoid the unbalanced load and the danger of dumping. When using, first connect the quick connector of the manual pump to the top, then select the position, and tighten the oil drain screw on the oil pump to work. Loosen the oil drain screw and unload the oil cylinder.
