I broke out my 3/4" air gun for it's first use and it wasn't up to the job. I went to the local rentall and they said they didn't have a 3/4" air gun. On the way out I thought, I wonder if they have a 3/4" electric. It turns out they did and it worked fine. I eventually got my 3/4" air tool working. It turns out that the oil inside from the factory did not work well after sitting in a cold garage!
