When I see the picture above, my first thought is: "That's the last time that window and side panel will remain intact." due to the HiLift. The base of the jack is too far away from the body of the truck, possibly causing the jack to kick out and jam the top into the side panel and glass.
Whenever one starts to tilt, it usually goes wrong quickly. Then the operator tries to brace it and hold it in place while the tuck/tractor/wagon/car falls off and jams the HiLift into whatever part it was on, then slides off the side and continues to inflict damage. By the time it's done, it usually has caused more damage than it's worth. At least for the first 10 times you use it. Then you really learn HOW to use it, and more importantly, how NOT to use it.
