Use method and precautions
1. Flatten the end of the head with the handle, tighten the return valve stem clockwise.
2. Turn the handle off, and the piston rod will rise steadily to lift the weight. Because of the limited position device in the body of the dry jack, the item will not rise to a certain height.
3. The return valve rod is slightly loosened counterclockwise, and the piston rod slowly drops. If there is a load return valve stem can not rotate too fast, otherwise the speed of decline will be dangerous.
4. Before lifting, the weight of the lifted object must be estimated. Do not overload it.
5. When using, the center of gravity of the lifted object should be determined, the focus of the dry Jack should be chosen and placed smoothly. At the same time, the soft and hard degree of the ground should be considered. When necessary, the rigid board should be padded to prevent the inclination or even inclination of the jack when lifting.
6. The jack is only for lifting. After lifting, support should be used immediately to prevent the danger caused by the failure of jacks.
7. If several jacks are used together, the lifting speed should keep synchronization, and the load of each dry Jack should be balanced, otherwise there will be the risk of dumping.
8. The Jack uses 15# mechanical oil. The jack must keep enough filtered working oil, otherwise it will not reach the rated lifting height of
9. When using, it should avoid sharp vibration.
