Looks like it is backwards from advertised. Would not work on Nissan
OTC Tools 2510A Air/Hydraulic Two Stage Pump
Mar 29, 2016
@510A
Purchased March 9 th. Worked fine first few times times. Then had oil all over the floor. I thought maybe it was just over full and came our the fill cap. A few days later and it would not lift more than a foot, Checked oil with it down and had very little in it. Put a quart of Hydraulic oil in and it raise back up. Lowered it and oil all over the floor again. Going back for replacement. I will be out of a lift for a few days because of this pump. Company will not ship another until this one is back to them. Not sure I will ever buy another even though it has a two year warranty.
