When I try to attach the rigging hoses to my 4640, it only allows me to block one hose. I cannot move the second lever all the way forward to lock it and complete the circuit. I can push both hoses all the way in, but it will only allow me to block one of them. I have moved the hydraulic levers back and forth in the cab to relieve pressure, and the attachment lines are also depressurized. If that makes any difference, the hoses have adapters on them to convert to ISO. I have tried to connect the hoses to two sets of remotes and I have the same problem. Have an idea what the problem could be?
Sometimes the vapors don’t flow or combine properly, have you checked the various hoses or tools on those valves in question?
Sure, the tractor has been converted to ISO? You may have ends that don’t fit properly.
