Your boat has several separate air chambers with valves. Each valve has a pushpin in the middle that can be pushed in and rotated. When the pin is in the "out" position the valve is closed. When the pin is in the "in" position the valve is open and air will escape. When storing your boat you will push the pin in with your finger and turn it a quarter turn to lock the pin in the down or "in" position. This will allow the air to escape from your boat chambers.
If you need to fit your boat in a small space, or you want to get it back in the original box, you can use a shop-vac style vacuum cleaner or a 12-volt electric pump to deflate the inflatable keel and each air chamber. Close the valve and install the valve protector cap when done. If you are not worried about the boat being a small as possible when stored you can simply let the air escape from the valves as you roll up your boat. The bag that comes with each boat is large enough for a loosely rolled up boat to fit in.
If your boat is equipped with a Plywood or Aluminum Floor, it is now time to remove it. Remove the stringers from either edge first. Now, lift the floor about 10 inches at the rear most seam (between the last and second last floor pieces). Carefully lift the pieces out and place them in their carrying case.
If your boat is equipped with a High Pressure Air deck Floor, remove the air from it and install the valve protector cap. It is not necessary to remove the floor from the boat unless you wish to clean the boat at this time.
The valves should be in their "open" position for disassembly.
Make sure that each chamber in your boat has a very small amount of air in it to prevent severe scrunching of the fabric so that damage doesn't occur while your boat is being stored.
