Hello fellow enthusiasts! I'm am still some what new to this awesome forum and already has helped me out a bunch. I Was given this awesome floor jack by a buddy and it doesn't pump or anything. I have filled oil tried removing air etc and still nothing. I read the jack sticky and still nothing. The only label on it left is the 'made in Japan' Sticker. Which by me and it's age is better than made in China. So anyone have info or know brand as to I guess I'm going to have to rebuild. Figured I would post before messaging Hiball. Thanks in advanced.
