I have an old Coleman CleanMachine Powermate 1210 electric pressure machine - - Model PW0731210. I am looking for the operator manual in general, but would like to know the PSI the machine puts out. I have had to replace the hose and wand a few years ago, but the machine still operates well. Recently I have looked at several attachments to clean my driveway, sidewalk, etc. and each device gives a range of PSI for the attachment to work efficiently.
