I realize that the plug you see is on the top of the barrel.
Think about the "normal" position of that plug on a jack that is
standing on its own base plate. The proper level for the fluid
would be level with this hole when standing up.

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.
