I've read the manual and have gone through three c02 canisters trying to pump up my bl***** tyre, thought i'd try it before getting stuck out on the road. The air comes out but doesn't seem enough and I end up deflating the air that has gone in. I have the 16oz canister which should do the job. It seems the air isn't coming out in one gradual stream, as I screw the canister in and thinking it has released all the air there's more air that comes out which then turns into white powder, any advice would be appreciated.

Basically, screw in in all he way, place it on the valve and then unwind it slightly and it should do the inflation bit for you.
When you get home deflate it completely, partially pump it up, deflate bit again to release all the gas and then pump it up with an air pump and you will eliminate the slow deflation that occurs if you you leave it 'gassed' up.
I have just typed this after a few pints, dinner, and a few reds in rainy Melbourne so naturally am open to corrections and highlighting of of errors - hic :)

It sounds like there is an issue with the valve or the inflator.
A trap for newbies with presta valves is you have to unscrew the small knurled lock nut on the top of the valve.
However I am assuming that you let the air out of the tire so the lock nut should be loose.
I have never used this particular brand of inflator.
Is the white powder ice from rapidly expanding CO2?
Looks like a nice gadget.
On my third attempt I did manage to get air into the tube more like 3/4 pressure but seemed like the entire co2 wasn't being delivered. I'll have another go tonight when I get home but thanks for your advice Mike and Don, I also went down to the local bike shop where I worked (and purchased the new tubes yesterday) but he wasn't that helpful and offered my some new co2 canisters. Me thinks I'll go somehwere else when I want some more service next time!
