Took a minute to take apart to check if oiled. It was. Has all the tools for that step but only will need to be done periodically. Customer installs 1/4” air connector to the rivet tool but I suggest buying a swivel air connector (which I did) as hose connects to right side and makes it easier to move. Riveter works great and I found the plastic cap is actually used for catching the rivet shafts. Quiet and sturdy.
