Hydraulic jack, is a jack that uses a plunger or a hydraulic cylinder as a rigid jack. When the vertical hydraulic jack is in use, it often encounters the situation that there is air in the cylinder, so that the hydraulic jack cannot be used normally, and there will be a drop after the jack, and some will not rise. This kind of situation mostly occurs when the jack is not properly placed when it is not in use, and it is not maintained for a long time.
How to deal with this situation with hydraulic jacks?
In this case, the user can find a rubber plug on the back of the jack and knock it out with a flat-head screwdriver. The gas will be eliminated while knocking out, and then press the rubber plug back to its original position.
Note: When dealing with the above problems, do not operate when the jack is lifting heavy objects, so as to avoid accidents! !
It is very simple to deal with this problem, but users should be reminded that hydraulic jacks are special equipment tools. Before use, the appropriate model should be selected according to the weight of the heavy object, and the appropriate tonnage should be used for hydraulic jacks. There are clear maintenance and operation procedures for the use of hydraulic jacks, and strict violations of regulations.
