Got it together yesterday, would not pump at all, fiddled around and said bad words due to the lack of a manual. The booklet in the box is a parts blowup diagram only, with every fitting called a screw. I didn't want to eff up anything, so I called Redline, got a tech guy fast, and was walked through the bleeding operation, so my 4.9 instead of a 5.0 is due to the lack of a piece of paper in the box to help a new owner get it going. The press looks nice and makes my workbench look better!
