Safety first.....keep your feet and legs a little back from the screw and make sure you don't have anything hanging off of you...no straps, laces ,scarves...nothing. There's a right and a wrong way to hold the thing...you should have a kill switch right at your fingertips. If you don't it's backwards..stop and turn it around. Back in '79 or '80 a young man I worked with managed to kill himself with one of these things...IM me if you want the gory story. That's my advice, be careful with the gas too, then go out and have all the fun you can...tight lines
