My Floor Jack needs hydraulic fluid. It dont raise as high as it used to. I have never had to add fluid to one of these. I got a bottle of the fluid, found a plug on the top of the jack cylinder which I imagine is the place that gets the fluid, and was ready to fill it. Thats when I realized that I have no idea how full it should be, and whether removing this plug will cause the fluid to shoot out (is is under pressure with the jack lowered?). I decided to ask for a little advice before I open the thing. Everytime I think I know everything, it seems there is something new to learn every day !!!!
Anyone????
Thanks in advance for all help.
