try this , kill the machine , entergize the igniton without starting the machine , light up the aux hydraulic button on the dash , press the aux hydraulic button on the controll stick and you should see the hoses jerk and go limp -------------- there are quite a few different procedures over the years as the machines progressed , some 763's machines , which I'd bet your has , have a aux pressure release that works by turning the key from the run postion with the engine running to the accessory position in one quick turn and hold it for a second in accessory , the newer machines have a button on the left console to release the pressure and the quick couplers on the manifold are spring loaded to release pressure when you push in on them ------------------if all else fails loosen a hose to the attachment to get out a bind , when using a grapple make sure the teeth are closed before removing the q.c.'s as it will be hard to put them back on later
