jimoshel Posted July 5, 2011 Share Posted July 5, 2011 Vacuum pressure=15 to 22 is operating range. 17 is considered norm. Link to comment Share on other sites More sharing options...

Pete M Posted July 6, 2011 Share Posted July 6, 2011 I would bypass the CAD permanently and ignore the light. :thumbsup: Link to comment Share on other sites More sharing options...
deziped Posted July 6, 2011 Share Posted July 6, 2011 A presser operates an iron, and pressure blows the steam out of it. Link to comment Share on other sites More sharing options...
