Took a minute to disassemble and check for grease. It was. There are all the tools for this step, but you just have to do it regularly. The customer installs a 1/4" air hose on the riveting tool, but I suggest buying a swiveling air hose (which I did) since the hose connects to the right side and makes it easier to move. The riveter works great and I found that the plastic cap is actually used to grip the rivet rods. Calm and strong.
