First I cursed, but then read on a forum how to do it properly. Unfortunately, no guidance is .... If you're alone, you go really better than with the pump. Valve pure, naturally with the smooth side. Only as far as it fixes into place, otherwise the input is overstretched. Then highlight and press the air as good as it just goes in Richung valve. Strongman you can lay on it and roll the body toward the valve. The air escapes from the valve is not always alone. Then press the palms on the core adjacent to the valve, so that the water pushes the air upward. The valve opens and a hiss is audible. If water comes out of the valve, you have pressed to Dolle, a little more feeling ;-) Everything as many times until no more "gurgles" in the mattress. The air collects better on the valve when the entire filler neck is slightly raised from time to time. With a little practice goes quite well, takes no longer than 5-10 minutes. I wish you success.
