First Time Setup
To adjust the air pressure, find the air regulator and pull up on the black round knob to unlock it. Then turn it clockwise to increase the air pressure or counter clockwise to decrease the air pressure.
Now add a few drops of water into the paint cup or jar. Press down on the trigger to start the air flow and pull back on the trigger to start the fluid flow. The more the trigger is pulled back, the more fluid is released.
