[Shop-talk] jack bleeding

[Mark Andy]

Howdy,

I have a 2 ton low clearence jack I got from Sam's club.  Dunno what the 
brand is or whatever.

Its never really lifted worth a damn, and I suspect that its due to air 
being in the system.

Can someone explain the fundamentals of jack hydraulics to me?  I want to 
bleed the thing, but I don't have a decent picture in my head of where the 
air is, how the hyraulics work, how to bleed it well, etc. etc.

Thanks!

Mark
