When the slide is extended electrically, the arm should begin to rotate and the end of the arm should should just clear the RV body (no contact).
You may not be able to fix your problem with an adjustment because it would be very difficult for a manufacturer to anticipate the position of the arm when the slide is extended. It's far more important that the arm is properly adjusted in the retracted position. And there's always the football/beachball fix
