I was at the ZipDee factory and had mine adjusted. The spring tension is adjusted to the point that the awning will not roll up by itself when fully extended. It does take help to start it but I find a gentle push is all I need.
Get a helper and a prop. Extend the awning as if you are going to leave it out. Put the prop under the roller tube for support. Separate the arm on the bottom of the awning roller tube that returns to the coach. Hold onto it and don't let it go. Wind that arm around the roller tube to add tension. The helper is to make sure the awing doesn't fall off the prop and to stabilize the awing while you work on it.
By the way. ZipDee makes a kit to reverse the arms with the claws so that the claw attaches at the roller tube instead of high up on the wall of the coach. Made the change and love it as you don't need the fancy awning rod to release the arm.
