when i turn on the gas, and i shoot, it makes the sound like when you turn off your tank and shoot to get rid of the remaining pressure in the hose. what is wrong?

i have air in my tank and its at about 1500 psi

output pressure 750

i haven't oiled my valve. could that be the problem?? is there something wrong with the velocity? HELP! I HAVE A GAME TOMORROW!

pfft

oh nevermind....i solved it, the velocity adjuster was one turn too far out...so the velocity was low.
