It works w/o damaging anything if you make sure that the standard (The long metal bar with the slots in it) and the handle (The long hollow pipe) are not going to swing into the side of the truck or a person, etc...when the truck moves.

Essentially...lets say your undercarriage is hung up on a hump...and you can jack the X up enough to get the underbelly off the hump...but, once up, you don't have a way to drive off unless you leave the jack in place...so you do.



The best solution is to place stuff under the tires once the X is up to make it clear the hump, lower back down, take out the jack, and THEN go...but sometimes, there's nothing available.

So...you jack it up...picking a point that you know will be pivoted from.

Once clear of the hump, wrap a blanket/towel, etc on the standard, remove the handle, get everyone clear, and drive off the jack...

You will swing forward on the jack, pivoting from the jack point...kind of like a slow weak short pole vaulter would do....clearing the hump, and setting you free.

You then go back and get the jack, make sure its OK, and continue on your merry way.
