Usage: 1. Check whether each part is normal before use. 2. When using, strictly abide by the provisions in the main parameters and avoid ultra-high overload. Otherwise, when the lifting height or lifting tonnage exceeds the provisions, serious oil leakage will occur in the electric hydraulic jack department. 3. For more information about motor pump, see motor pump instructions. 4. The center of gravity of heavy objects should be moderate. The focus point of electric hydraulic jack should be reasonably selected. The bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be taken into account. Whether to pad tough wood and whether to place it smoothly, in order to avoid weight sinking or tilting. 5. After the electric hydraulic jack lifts the weight, the weight should be firmly supported by the support in time. It is forbidden to use the ultra-high pressure and large tonnage electrical Jack as the support. If you need to support heavy objects for a long time, please choose self-locking Jack 6. If you need to lift several electric hydraulic jacks at the same time, please choose type synchronous Jack, in addition to correctly placing large tonnage electrical Jack, multi-top splite-flow valve should be used, and the load of each large tonnage electrical Jack should be balanced, and attention should be paid to keeping the lifting speed synchronized. It is also necessary to consider the situation that the ground may fall down due to uneven weight to prevent danger caused by tilting by weightlifting. 7. When using, first connect the manual pump quick connector with the top, then select the position and tighten the oil drain screw on the oil pump to work. To lower the piston rod, slightly loosen the manipulating fuel pump hand wheel in the counterclockwise direction, and unload the oil cylinder, the piston rod will gradually decrease. Otherwise, it will be dangerous to drop too fast. 8. This electrical Jack is oil pressure retraction. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the ultra-high pressure large tonnage electrical Jack. 9. Users should never exceed the rated stroke when using it, so as not to damage the electric hydraulic jack. 10. Avoid severe vibration of the Jack during use. 11. It is not suitable for use in workplaces with acid, alkali and corrosive gases. 12. Users should check and maintain regularly according to their usage.
