Colorado XT (airing up issues)!!!!!

[sinergy]

That adapter looks similar to a Halkey Roberts adapter. On the inside of the adapter is there a pin or a little screw ? The pin or screw pushes the valves center post down to open the valve for inflation. The first adapter I got had a screw it would turn the valves center post when I would twist to lock into the valve. So when I removed it from the toon it left the valve wide open.

If its like the halkey roberts adapter I had then turn the valve center post closed twist the adapter into the valve, and see if you can inflate then twist the adapter out and it should close the valve.
