I bought one of these after watching Eric O at South Main Auto take off just about any fastener with this gun. I'v I'm running 120 psi at the compressor with 3/8" lines and coupling and I can't remove a 100 lb ft torqued lug nut. Is this thing defective? It is brand new. I'm getting less than 1/4 of the listed working torque. If I hold the socket in the highest reverse setting, the thing kicks into hammer mode. This doesn't seem like it is working right.
Anyone have any experience on this impact? Mine seems to be a lemon.
