there is a little switch looking thing that has to be lifted up from the pump then insert the valve into the bike pump and then puch the switch/lever back down and start pumping then to take off lift lever and quickly take pump off valve otherwise you will lose air you just put into tire
After a call to the customer service people who were more confused than I was, I figured out how to mount the bracket to the handle bar. Believe it or not the Zefal guys did not have an instruction manual on the product they sell. So here is how it works...
You have to run the hard plastic strap around the handle bar and push it into a gap between the plastic nut . It's such a small gap that you will have award time finding it. Once you tighten the plastic nut the strap will advance slowly until the end will come appear on the other side. That's all there is to it.
Now why the heck could they not put a picture of this on the box? Perhaps job security for the Zefal guys?
I was having problems with the installation also, but my husband finally figured it out. Just start the end of the strap at the screw, as you tighten the screw with the Allen wrench it will thread the end thru and will get tighter around the post of the bike. It works perfectly and now I can use the GPS on my iPhone to record my rides. Hope this helps!
The needle part for blowing up basketballs and the like simply unscrews from the bike tire part. Depending on the type of tire you have, you might have to get an adapter. If it looks like your car tire stem, it's called a Schraeder valve, and you should be all set. If it is thinner and has a tip that you unscrew, it is called a Presta valve, and you may or may not need an adapter depending on your pump.

If your pump is not double sided (which the one in the picture looks like) the rubber valve can be reversed very easily by unscrewing the outer cap where you usually insert the valve and turning the little rubber valve around before screwing the outer cap back on.
The gauge measures three different amounts. Be certain that you have it set to PSI. Then set the target PSI. The green LED indicator will then flash when you are within
5 PSI of your target and will flash constant when the target PSI is
