CAT 247B Hydraulic Problem

    We have a CAT247B with some hydraulic problems. It seems like there is pressure in the system still. I am trying to get a rock hound made by CAT on the machine. It has been on and off the machine several times no problem. I have released all pressure off the machine side I think. I don't know if there is a pressure relieve switch or not. I can hook up the male hose first as you always should and the female hose will not budge. It only goes on half way then springs back at me. My concern is that there is still hydraulic pressure on the rock hound side. Is there a way to drain the hose? or is there a bigger problem that I am not seeing? Any one who has help would be greatly appreciated!!!! I need to get back running the CAT have a ton of work to do!!!! Thanks Boys

    There's a pressure release button on the upper right side of the cab, turn the key on (no start) activate the switch and roll/push the buttons for the aux.
    If there's no switch, just leave the key on with the seat bar down, parking brake off and do the same.

    I bet you still have pressure on the hound. Just break the fitting loose and let a little fluid out. Always remember to let the pressure off before you unhook it.
