You are looking at a beast of a pressure washer! This belonged to my buddy who was a painter. He upgraded to a brand new pressure washer and gave me this one. I honestly have no clue about this machine. All I know is that he used it for about a year and said it was awesome! It does have plenty of compression when I pull the cord. I would imagine that it could use a tune up just like everything you buy online I would imagine. I'm not 100% sure of the psi, but I believe I remember him saying something like 4000psi, but don't quote me on that please. Comes with wand but it's missing the metal rod, so you will need a new one. I do know this though, the Honda 5.5hp engine is actually worth quite the penny! You are buying as is.
