Precautions

1. Check whether each part is normal before use.
2. Strictly abide by the regulations in the main parameters during use, and avoid 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 oil volume of the manual hydraulic pump is insufficient, it is necessary to add hydraulic oil which should be fully filtered to the pump before it can work.
4. For the electric pump station, please refer to the manual for the electric pump station.
5. The center of gravity of the heavy object should be moderate, and the jack should be selected reasonably. The bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered.
6. After the jack lifts up the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the jack as support.
7. When several jacks are required to lift at the same time, in addition to the correct placement of the jacks, a distribution valve should be used, and a load of each jack should be balanced, and pay attention to keep the lifting speed synchronized. It must also be considered that the ground may sink due to uneven weight to prevent the weight from being lifted from tilting and causing danger.
8. The jack is a spring reset structure, after lifting, it can be quickly taken out, but the jack cannot be pulled by the connected hose.
9. Because the lifting stroke of the jack is short, the user must not exceed the rated stroke when using it to avoid damage to the jack.
10. Avoid violent jack vibration during use.
11. Not suitable for use in workplaces with acid, alkali, and corrosive gases.
12. The user should check and maintain it regularly according to the usage.
