Keep in mind that the rams (jacks) are not a pass through system. If you DO have hydraulic fluid running through the ram and it flows past the seals the ram is bad and will not maintain pressure or position in the jacks. To bleed them you can crack the fitting on the side you are running (extension or retraction) until the bubbles are gone. Keep in mind that the pump moves A LOT of fluid so be careful as it WILL get messy and do not run the pump dry.

I did one line at a time. I had the ram at near full extension then by hand moved it up to purge the line of air at the manifold. It would do the same on retraction as well as each side of the ram is a pressure side. Just crack the appropriate line and move the ram. It doesn't take much as the line doesn't hold that much fluid, at least on the front jacks. It is a 2 person job.
