Assembly is simple enough and consists of putting on the handles, the regulator bracket, and threading in the supplied 1/4" or 3/8" male air line connectors. I used the 1/4" connector. I do wish the jack came with better instructions, ESPECIALLY some specs to indicate a max safe PSI line pressure. If the jack rubber chambers blow out in your face while under pressure, you could be seriously hurt.I tested it on my Chevy Bolt, which it lifted just enough to slide the front wheel off with 80 PSI pressure from my 240V, 60-gallon compressor. For my 2014 Durango, 80 PSI just moved the suspension up a bit. 120 PSI almost lifted it, and 140 PSI slooowly got the front wheel about 1" off the ground. Based on this, I don't believe this jack can really lift 6000 pounds. Considering that my 5500 lb Durango still had three wheels on the ground, I'm guessing the jack lifted, at most, 2000 lbs.Compare this to my 6000 lb hydraulic floor jack which effortlessly lifts both cars significantly higher off the ground.Beware that if you have rocker panels or body cladding that is close to the lift points, you may need a thick spacer since the jack surface is so wide. I got a pinch weld block that's about 1.80" thick and it still squeezed my plastic rocker panel a bit by the front wheel.
