Bottom Line HELP

[Paint Bulley]

When I go to take my Co2 off my bottom line, right when it gets to the end it makes a big bang and pops off, Why does it do this?

Thanks,

Because it is still under pressure. You need to shoot out the co2 that is in the bottom line before you take the tank all the way off.

Haven't you ever been tought how to take your tank off??
Anyways here it goes. First make sure there is no paint in the chamber, than start unsrewing the tank slowely fair some as you do this, continue until it is unsrewed enough to where the pin is not long pushed down in the tank than fire out the rest of the air in the line.
