tarkenton Report post Posted October 9, 2014 Can anyone tell me where and how to check the pressure at the 625 manifold, I thought it was the press switch, purchased a new switch and installed it did not help, slides will not retract and jacks will not extend. I am new to the forums so any help will be appreciated. BobT Share this post Link to post Share on other sites
dickandlois Report post Posted October 9, 2014 Bob, Welcome to the FMCA Forum! You did not mention if you have the owners manual, so this is a link to the 625 systems. http://www.hwh.com/ml35963.pdf Page 29 shows the pressure switches 50 lb and 3000lb. locations and the hydraulic plumbing. http://www.hwh.com/ml41240.pdf About the same Rich.
