Both bows are the same size and therefore interchangeable. When placing the bows in the side rails, it is easiest to place the spring-loaded bow end in first. When placing the bows, locate the small notches (arrow) in the side rails. These notches receive the tang on the bow ends and help the bows seat into place. 5. Stow both bows and the front and rear rails in the storage bag as shown. When all components of the tonneau cover are secured in the bag properly, zip the bag shut. Reverse the procedure to reinstall the tonneau cover using the following suggestions: When reinstalling the front rail, start by holding the back edge of the rail (edge nearest you) up and then twisting the back edge down while pushing it into place. When reinstalling the tonneau cover, start at the front, near the cab. Place the plastic lip into the front rail, then the rear rail, and finish with the side rails. To clean the tonneau cover, use mild soap and water. If necessary, use a soft bristle brush to remove dirt trapped in the grain of the material. 2-83
