There are three maintenance methods for the horizontal jack that cannot be lifted up: one is to check whether the oil drain valve is completely closed; the other is to tighten the oil drain handle and then loosen it for half a turn, and the multi-pressure handle will discharge the air; the third is that the dust enters the hydraulic system or the hydraulic oil in the cylinder Too little, it is impossible to open the oil hole bolt of the oil pump, replace the hydraulic oil or replenish the hydraulic oil, and tighten the oil hole bolt.
Second, how to use the horizontal jack?
1. First of all, whether it is repairing a car or lifting other heavy objects, be sure to find the reference point. A place that is too fragile can never be used as a support point, so it is easy to break the object.
2. After the support point is determined, the pressure rod must be inserted into the casing in front of the jack, so as to apply pressure to the jack, and then the other end of the jack will rise.
3. After installing the pressure rod into the casing and ensuring that the installation is stable, you can press the rod down continuously, so that the end of the jack will slowly rise up through hydraulic action until the weight is pushed to a suitable height. Pressure can be stopped.
4. At this moment, the heavy object will be in a suspended state, and the object can be repaired or inspected. During the period, do not tamper with the jack. After the repair is completed, you need to relieve the pressure of the jack and then gradually put the heavy object back to its original position. How to relieve the pressure? ? Different brands of jacks have different pressure relief methods, but most of them will have a screw switch, and the jack can be relieved and reset by turning it counterclockwise.
