Review on Hitachi NV45AB2 Roofing Discontinued Manufacturer by Kenny Hrdlicka

I bought this nail gun to cover the roof of my mother's house. I'm not a professional roofer and I don't use this nail gun every day. Anyway, I've been using the live crap from this nail gun for two weeks and haven't had a single malfunction. I had to adjust the nail depth by turning the depth gauge just below the front of the nail gun. I've read in other reviews that you have to put a few drops of oil on after every nail roller I've done and it just kept rocking and rolling. I bought a swivel fitting and Bostitch Premoil 4oz Premium Air Oil at the same time. Thank you and God bless.
