How to repair a cheap jack

Hi guys, in this period I have received so many requests about problems with lifting cheap jacks!
The most frequent problem is that they do not lift, or the cylinder does not hold the pressure (this usually occurs when there is dirt in the ball seats or damaged seals)...
Today I made this video which I hope will be useful to all those who have now given up. Furthermore, replacing the gaskets and o-rings on these models is really cheap, but be careful, because not all models have metric gaskets (the one in the video had inch gaskets).
I hope you enjoyed the video, subscribe to the channel and like!
THANK YOU
