How to use hydraulic jack

1. Before use, you must check whether all parts are normal.

2. When using it, you should strictly abide by the regulations in the main parameters, and avoid over-height and overloading. Otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the electro-hydraulic jack.

3. For electric pump, please refer to the electric pump instruction manual.

4. The center of gravity of the heavy object should be moderate, the focus point of the electric hydraulic jack should be reasonably selected, and the bottom surface should be flat. At the same time, the soft and hard conditions of the ground should be taken into consideration, whether it should be lined with tough wood, and whether it should be placed smoothly to avoid sinking or tilting under the load.

5. After the electric hydraulic jack lifts the heavy object, the heavy object should be supported firmly with supports in time. It is prohibited to use ultra-high-pressure large-tonnage electric jacks as supports. If you need to support heavy objects for a long time, please choose YZL self-locking jack.

6. If several electric-hydraulic jacks are required to lift at the same time, please use the TYZF synchronous jack. In addition to correctly installing the large-tonnage electric jack, multiple diversion valves should be used, and the load of each large-tonnage electric jack should be balanced. Pay attention to maintaining Lifting speed is synchronized. It is also necessary to consider the possible sinking of the ground due to uneven weight to prevent the dangerous objects from tilting.

7. When using, first connect the quick connector of the manual pump to the top, then select the position, tighten the oil drain screw on the oil pump, and then it can work. To lower the piston rod, slightly loosen the handwheel of the manual oil pump in the counterclockwise direction. The oil cylinder will be unloaded and the piston rod will gradually descend. Otherwise, it will be dangerous if the descent speed is too fast.

8. This electric jack is retracted by hydraulic pressure. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the ultra-high-pressure large-tonnage electric jack.

9. Users must not exceed the rated stroke when using it to avoid damaging the electro-hydraulic jack.

10. Severe vibration of the jack should be avoided during use.

11. Not suitable for use in workplaces with acids, alkalis, and corrosive gases.

12. Users should perform regular inspection and maintenance based on usage conditions.
