Method of use: 1. Check whether each department is normal before use. 2. The regulations in the main parameters should be strictly observed when using. It is absolutely necessary to avoid super overload. 3. Please refer to the instruction manual of electric pump. 4. The center of gravity of the weight shall be moderate, and the power point of the electro-hydraulic jack shall be reasonably selected. The bottom shall be flat. 5. After lifting the weight, the heavy weight shall be supported firmly with the support in time. It is prohibited to use the electric jack with large tonnage of ultra-high pressure as the support. If the weight needs to be supported for a long time, please choose self-locking jack 6. If several electric hydraulic jacks need to be hoisted at the same time, please choose type synchronous jack. In addition to properly placing large electric jacks, multiple split valves should be used. It is also necessary to consider possible subsidence due to uneven weight and to prevent the risk of tilt by the weight. 7. When using, first connect the quick joint of manual pump with the top, then select the position, tighten the oil drain screw on the pump, and then work. To lower the piston rod, loosen the hand wheel of the manual oil pump slightly in the counterclockwise direction. Otherwise it will be dangerous to fall too fast. 8. The electric jack is retracted by oil pressure. After hoisting, it can be quickly taken out, but it is not possible to use the connected hose to pull the super high pressure electric jack. 9. Please do not exceed rated travel when using by the user, so as not to damage the electro-hydraulic jack. 10. Avoid violent vibration of jack during operation. 11. It is not suitable to be used in workplaces with acid, alkali and corrosive gases. 12. The user shall check and maintain regularly according to the use situation.
