Those are excellent jacks....... tip, it takes a soft touch. When you close it down to raise the car, just close it. No need it torque the handle, as you might be use to with junk jacks.
If you put to much into it, it will fight you when you bring the car down. Dropping the car, instead of lowering it
I am sure this makes no sense, cause it is imposable to put into words what I'm trying to get across.
Another way of saying it. If you find that lowering the car. It is dropping the car, instead of a smooth steady speed down.
Use less man grip, when setting up to raise the car.
That jack is so smooth, you have full control of the speed coming down. Like a motor cycle throttle, you can speed up or slow the motion.
Enjoy that jack it is really really nice when you get the hang of it.
Don't you just love the size of the jack pad, just one great jack
