Servus together. I’ve read some articles here and at Google. But not really found something useful. The following problem I have tested three impact wrenches. None got the wheel screws of my car solved.. That after about half a year the wheel screws need the factor 3, i.e. minimum 420NM release moment, is with aware. Auto: BMW G21, 140NM tightening moment. Devices: Einhell, Impaxxo 400, release moment = ? Makita, dtw300, release moment = about 700 NM maki ta, dtw700, release moment = approx. 1000 NM 17er nut = as good as new. All devices were operated with a 5ah battery. Fully charged. As soon as I have loosened the raven screws by hand, tightened them again with 140NM, all three devices could solve them again. But that’s not the point of the matter. I don’t want to open them manually after a session, but machine hehe. Do you have some advices? Which device could it pack? Or do you actually have to use an air operated impact screw r and Kessel get to the story ? Thank you very much
