I have the Hein-Werner 3 ton service jack. It's works well. But, low-profile it is not. Ordered it through Amazon a few years ago. The hydraulic cylinder leaked right out of the box, but Hein-Werner customer service sent me out a new cylinder. I was a little angry about replacing the hydraulic cylinder on my brand new jack. But figured that was easier than trying to ship back. Has no issues lifting any of the vehicles I own.
Any chance you identified the source of the Hein Werner leak during the shipping? The Hein Werners have a reservoir vent, and if the jack is turned sideways or upside down, the oil will leak out. I’d say it would be a miracle if oil didn’t leak out from the vent and go everywhere During shipping. When you get a replacement cylinder, they are shipped with a screw plug instead of a vent In the fill hole. If you have a screw plug in the fill hole, it should be replaced by a reservoir vent. The vent increases pump seal performance transferring oil during lift and a smoother, more consistent lowering of the jack.
