HI I have just got a HF-360 inflatable, but it didn't have a manual with it. I was hoping that one of you could tell me of any important aspects of the manual that you think I should know. Most importantly there is a yellow-backed clear strip on the inside safety tube (number 1 tube) with a black strip on the inside. There are the letters "A" and "B" marked on the clear strip, but I am not sure how to interpret the markings with out a manual!<br /><br /> Can any one tell me how to inflate it correctly or can any one email a copy of the important bits?
