I recently purchased a Ridgid 3300 PSI Pressure Washer with a Model 3DNX27GSI Cat pump. The main reason I purchased this power washer over a competitors was that I wanted a pressure washer that included a Cat pump. I was disappointed that the manufacture (Rigid) did not include any info about the pump. They did include a socket type tool that appears to fit on the bottom of the pump, but they do not say what this is for in their product manual. I am assuming it is to change the pressure, but that is a guess. Also, on the top of the pump it had a sticker that said “Caution, remove oil cap lable and plug before starting pump” They did not mention this in their manual. I removed the little plug, but it appears that the oil will leak out of this whole. My main concern is that the pump had oil all over it when I unpacked the box. It also appears the oil is slightly below the red dot on the little round window on the side. I assume this means that the oil is low. Last, but not least there are no instructions on pump maintenance supplied with the pump. Does anyone have any knowledge on these pumps and how to service them?
