    Three things that will cause the right wing to retract on it's own...

    1) Primary relief valve stuck open/damaged
    2) Secondary relief valve stuck open/damaged
    3) Position "D" pilot operated check valve stuck partially open or seat damaged

    You can pull them out of the manifold and try cleaning them and check the springs and seats for damage.. but in most cases you'll usually find a damaged one and need to replace it..

    Here's the Western manual so you can familiarize yourself with the valve locations....
