How to inflate bumpers and fenders.
Here is how you inflate your new Big Bumper Co boat bumper.
1. Unscrew the gray cap at the end.
2. Press spring with the yellow tab clockwise (works with some other pumps as well).
3. Insert the pump into the bumper.
4. Turn on your pump and inflate your fender.
5. Once inflated to the desired amount of air, remove the pump and twist the yellow spring cap counterclockwise.
6. Finally, screw on the gray end cap.
For best results use an approved pump. Remove the cap and inflate it with one of the recommended pumps.
