Query: DeWalt Framing Nailer

I ordered this March 9. Recieved it a week later. Didn't use it for 2 more weeks. Build one wall in by basement and the driving piston started freezing, check oil, good, reset, drives one nail and the piston is stuck again. Checked all normal items, pressure, connections, oil, mechanicals, etc. This thing sucks.
