Commuting - Refilling an Air Zorn?

Howdy - someone gave me an Air Zorn - no box or instructions, I can't seem to figure out how one would go about attaching a pump to refill the air bottle - anyone have one of these horns and willing to enlighten me as to how to recharge the bottle? Thanks!

flip the top cap off and you should see a schrader valve. attach a pump there; i think the max psi is 80.

i belive there is a red knob on the side that has to be in the correct position to allow it to fill,i am still trying to figure mine out also

my first tire pump was actually a pump for an air Zorn . I bought it at the CABDA bike show in Rosemont Illinois.

Let me help you, my fellow air-horn blasters. :)

See the red knob? It controls the volume. The settings are indicated with a - (low) and a + (high). There is a small portruding edge on the knob that allows you to see if it's pointing towards the - or the +. As you can see in the picture, the knob is pointing backwards. That is the - setting. When you are going to refill, you need to put it in the loudest setting (+).

Then you flip the top cap off, like Veganheart said. When doing this, use an upward motion and don't use too much force. You can do this with your thumb. The cap will now look like this:

You now see the Schrader valve that you attach the pump to.

Tip: when you are going to refill, make sure there is no more air in the bottle or else there will be a blast while you are pumping. This happened to me once which made me feel quite silly. :)

IMO, the low setting is quite useless because you need the full output when in traffic and you don't have time to constantly adjust the output everytime you encounter a pedestrian or other cyclist (aside from the fact that the knob is practically impossible to reach while riding). I just use a bell for pedestrians and cyclists and use the horn in the loudest setting for vehicles (and pedestrians with walkmans ;) ).

I've seen these things around... How loud are they? And how many blasts does one get to a refill?

I just got one last week. They are VERY LOUD. I haven't timed it, but I think you get about 30 seconds worth. This should be plenty for even the longest ride. I haven't used in anger once yet. The biggest problem I had was finding a place to hang it.

Thanks Sp@eder i bought one at LBS we played with it ,set it off ,scared both of us but LBS owner through out the instructions so i have been struggling with getting it filled,and yes it is loud,and yes i have used it in anger,well worth the money,I do wish the button could be closer to my hand grip, wonder if i should get another and have two??

I had that problem too. I first mounted it somewhere on the bar where I had to take my hand from the grip and then press the button. The problem with this is that in traffic, where you can find yourself in a risky situation within moments, you need to be able to press the button in a split second or chances are the situation has changed in a way that a horn blast is no longer needed or you got hit within the seconds it took you to move your hand from the grip to the button. Seconds really count! Plus, it's not very safe because you loose some control over your bike which is particularly dangerous in a near-collision situation.

Anyway, I tried to put it as close to the grip as possible by moving the shifter a bit. It took some getting used to but now I can press it with my thumb without moving my hand. What kind of shifters do you have?
