I just recently purchased a new Milwaukee impact wrench 1/2 friction ring 1100 fastening and 1400 breakaway torq. I charged the batteries and the gun worked very well for like a hour. Then all of a sudden it would work anymore. Batteries still have full charge according to charger. I plug the batteriers in and the small light and the speed controls light up for a few seconds then it quits and the gun won’t work. It seems like if I hold the tightly it works for a little bit. Any insight or if a thread has already been made please point me in that direction. Thank you very much. First time posting.
