No Pressure from New CO2 Tank

[Terrance Wong]

I just filled a brand new 10 lb co2 tank, and installed the regulator. The tank valve is on full, and even after turning the regulator on full, I'm getting no pressure reading at all.

The regulator is a M3, and I've checked and confirmed that the main valve is not bent in anyway.

I'm sure there's air in tank because it's significantely heavier than before, and when I brought it home, it was almost ice cold. The regulator was lent to me, and was working fine only a few days ago. Anyone have any ideas?

Thanks,

Terrance
