1. Before use, you must check whether each part is normal.
2. Strictly abide by the provisions in the main parameters when using, and avoid over-high overload, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.
3. If the amount of oil in the manual pump body is insufficient, the N32 # hydraulic oil, which should be fully filtered, must be added to the pump before it can work.
4. Please refer to the electric pump instruction manual for electric pump.
5. The center of gravity of the heavy object should be selected properly, the jacking point of the jack should be reasonably selected, and the bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered, and the tough wood should be lined.
6. After the electric jack lifts the heavy object, it should be used to support the heavy object in time. It is forbidden to use the jack as a support. If you need to support heavy objects for a long time, please choose YZL self-locking hydraulic jack
7. If several electric jacks are required to lift at the same time, please choose synchronous jacks. In addition to correctly placing the jacks, multi-head diverter valves should be used, and the load of each jack should be balanced. Pay attention to keep the lifting speed synchronized. It is also necessary to consider the situation where the ground may sink due to uneven weight to prevent the tilt of the weighted object from causing danger.
8. When in use, 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. To lower the piston rod, loosen the handwheel of the manual oil pump slightly in the counterclockwise direction, unload the cylinder, and the piston rod will gradually descend. Otherwise, the descending speed will be dangerous.
9. The hydraulic jack of this electric motor is retracted. After lifting, it can be taken out quickly, but the connected hose cannot be used to pull the ultra-high pressure jack.
10. Do not exceed the rated stroke when using by the user, so as not to damage the electric jack.
11. Avoid severe vibration of the jack during use.
12, not suitable for use in the workplace with acid and alkali, corrosive gases.
13. The user should regularly check and maintain according to the use situation
