Things You'll Need
Instructions
Screw on the ASA adapter to your tank whether it is HP or LP. Attach the gauge to detect the level of nitrogen within the tank.
Release the nitrogen gas in the tank slowly by unscrewing the ASA adapter if it is an HP tank. Use the gauge to manage how quickly you are releasing the nitrogen to arrive at 160 to 200 pounds per square inch of pressure within the tank. This is called the operating pressure.
Increase PSI in the tank by releasing nitrogen from the tank. Unscrew slowly and watch the gauge until it is 200 PSI for a LP tank. For a HP tank, refer to the regulations of your league, but the pressure will be much higher. Continue applying gas until you've reached the HP level.
Cap the tank on your paint ball gun and remove the ASA adapter to complete inverting the weapon.
