the timely delivered pneumatic wrench should be used for a tire change where he unfortunately failed completely. I have it connected to a 220 liters per minute supplying 8 bar compressor otherwise supplied Anyway all pneumatic equipment my workshop and wanted him to solve the tightened with 80Nm nuts which I unfortunately did not succeed it could be from 16 nuts not a so resolve only after the solved nuts per wheel cross and already turning his hand were, the mother lies by "pneumatic impact wrench" turn off but this is utter nonsense to the two revolutions I would geschaft also by hand at the same time. The adjustment screw next to the compressed air connection, I tried to turn but I did not succeed with normal hand pressure. Maybe you could try the control device with pliers to adjust what but I did not do it because on the one hand for a new one is on the other hand, there is no guidance on the stand should how the pressure (if possible at all) can be established.
