Dirtdevil I think my 48 2 ton has that same system,when it came to me leaked around the control shaft. There was a screw worn off that let the shaft move out,not much , replaced it ,fixed it !! Easily lifts 8000 lb.white rock,spread it on the driveway. Makes you feel good when you don't have to scoop !!! Go to the pit get in line with the big boys,get scale ticket,clip it on the dash !!! Then haul !!
