A, horizontal jack top can not rise up how to repair?


There are three maintenance methods: one is to check whether the oil discharge valve is completely shut off; Second, the oil handle is tightened and then loosened two laps, and the gas is discharged from the pressure handle; Three is dust control into the hydraulic transmission system or the main cylinder gear oil is too little, can not open the gasoline pump inlet anchor bolt, jack company remove gear oil or fill the gear oil, tighten the inlet anchor bolt.


Two, how to use the horizontal jack top?


1, first of all, whether it is to repair the car or lift other heavy objects, we must choose the reference point, too sensitive site is certainly not as a fulcrum, it is very easy to top bad things.


2, after the clear fulcrum, you need to put the pressure rod into the waterproof casing in front of the hydraulic jack top, so that you can put pressure on the hydraulic jack top, and then the hydraulic jack top in addition to the head will lift.


3, put the pressure rod into the waterproof sleeve and ensure that the installation is secure, you can continue to press the rod down gently, so that the top end of the hydraulic press will gradually rise according to the efficacy of the hydraulic machine, until the weight to the appropriate relative height can stop the pressure.


4, when the weight will be hanging in the air, you can carry out maintenance or inspection of the jack custom objects, during the period of avoid running hydraulic jack top, after the end of maintenance must give the hydraulic jack top pressure relief then slowly put the weight back to the origin, how to relieve pressure? Different brands of hydraulic pressure relief methods are not the same, but most manual jacks will have a spiral power switch, the opposite direction can be turned to the hydraulic pressure relief calibration.


5. After pressure relief calibration, gently remove the hydraulic top from the bottom of the weight, then pull out the pressure bar, and put all the spare parts back into the original packaging box, so as to facilitate the next application. Avoid losing all the spare parts in it.
