Got my QuickJack all set up and running. Mine was missing the schraeder valves on the air assist cylinders. Not a big deal, picked a couple up and fixed the problem. Now I have several of the quick connect hydraulic fittings that are leaking. I'm going to re-seal the threads this week and if they continue to leak, will be calling QJ for some replacements.
Just a couple observations...
If you live in a cold climate, use the thinnest hydraulic oil they spec (ISO 32) or ATF. I used some for my tractor that's ISO 64 and it's a bit slow to lower.
Consider getting the SUV adapter posts. I noticed that due to the design of the front torque box, I have to pull the QJ out just far enough to clear the vertical flange, and that puts the rubber block on the inside edge of the unit. I might machine up some taller aluminum pucks with slots for the pinch weld so I can center the QJ under the lifting point. The SUV adapter posts should accomplish the same thing if you don't have access to machine tools.
Also, the car moves horizontally at it's maximum lift point. If you're putting the car on jackstands, be aware that you'll need to chase the stands until they begin to take the weight of car.
It might make a useful undercar jacking system, such as for a transmission.
Overall, I'm pretty happy with it and feel it's a good investment. As with any tool, it has it's plusses and minuses, and take some use to determine best practices.
