Hi, I took a look at the rollers. Still not sure whether is has side thrust adjusters as mentioned above. Will take a closer look tomorrow. My main concern is the ram bouncing. Any way to post a video of it?

When lifting the first ram is smooth, then the next ram bounces as well as the third. When lowering it lowers VERY fast until getting to the last (first?) ram then it lowers slowly. I tried tilting all the way back and raising to full height and lowering completely probably 10 times. Didn't make much of a difference. The Hydraulic res. is full and the fluid seems clean. Have no idea how old it is though. I bought it used.
