Mostly 3-4 pumps. Very nice feature.
You'll have hieght concerns with any jack. My exposure to them is carrying them on/off the trailer, over pit wall and to the golf cart. On the hiegh thing, we have to take body work off the car to even get under it but we have insert tubes on the side of the car and lift it left to right. For street cars w/ my standard heavy metal jack I usually have to lift the bumper by hand far enuf to wheel it under, the aluminum one is low enuf to slip in unassisted.

Hell I always thought a 2-ton jack was what it weighed, not what it lifted! <img src="/forums/images/graemlins/lol.gif" alt="" />
