First, how to repair the horizontal jack can not rise?

Horizontal jack can not rise there are three maintenance methods: one is to check whether the oil discharge valve is completely shut down; 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 master cylinder gear oil is too little, can not open the gasoline pump inlet anchor bolt, remove and replace the gear oil or fill the gear oil, tighten the inlet anchor bolt.

Two, how to use the horizontal jack?

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

3, put the pressure rod into the waterproof sleeve and ensure the installation of safe, you can continue to gently press the rod down, so that the hydraulic jack will gradually rise according to the effect of the hydraulic press, until the weight to the appropriate relative height can be terminated pressure.

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

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