Well, i took Haymans advice and returned the air impact and got the battery powered Herculees. 5yr warranty, 3yr warranty on the battery and charger. It zipped the nut right off the bolt like it was no problem. Same bolt i broke my 3/4 ratchet on. Thanks Hayman.
I believe that Hercules took the place of the battery powered earthquake and has a better warranty. I want one of those but as long as my old one is working I’ll keep using it. I keep mine in the truck with a metric assortment of impact sockets. It’s a lot easier to change a tire with that than a 4 way. Don’t let it hammer on wheel nuts very much because it will break the studs.
