Hey everyone, I have a Ryobi 2000 PSI 1.2 GPM electric pressure washer, I ran into a problem last season where it was turning on every couple seconds without the trigger being pressed, this season I turned on I ran it it was doing that same thing and then all the sudden it stopped pushing out any type of pressure it was almost as if it powered off and was just a hose pressure coming through the nozzle. I thought maybe it was something to do with the unloader valve but not knowing what I'm doing like an idiot I opened up the entire thing as you can see in the pictures not realizing that there was oil behind there so now I know I have to replace the oil in there what type of oil should I put in there and how high up should I fill it? I understand now that I have to remove those pins that were attached to that to avoid what I just did. Trying to figure out how to get this thing back up and running but before I can turn it on I know without a doubt I have to put that oil back in there if somebody can just direct me in the right way is to what type of oil I need to put in there I would appreciate it. Thank you
