Instructions for use of ultra-thin hydraulic jack
Ultra-thin hydraulic jacks are smaller and produce greater working capacity. Especially in places with a narrow space. And it has functions such as lightness, flexibility, and high jacking force. The ultra-thin hydraulic jack body is widely used in electric power, chemical industry, steel beams, bridges, machinery and other enterprises and exerts infinite power.
1. Before use, you must check whether each part is normal.
2. When using it, you must strictly abide by the provisions in the main parameters, and avoid excessively 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 N33 # hydraulic oil, which should be sufficiently 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 jack lifts the heavy object, it should be supported firmly with a support 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
7. If several jacks are required to be lifted at the same time, in addition to correctly placing the jacks, a multi-top diverter valve should be used, and the load of each jack should be balanced. Pay attention to keeping 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 separate jack is a spring return structure. After lifting, it can be quickly removed, but the connected hose cannot be used to pull the jack.
10. Because the lifting stroke of the jack is small, users should never exceed the rated stroke when using it, so as not to damage the 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
