What adjustment should be made after filling the gun with paint?

After filling the gun with paint, it is essential to turn the air adjustment out about half a turn to optimize the spray pattern and ensure proper atomization of the paint. This adjustment allows for the right balance of air and paint flow, which is crucial for achieving an even application without issues such as runs or uneven texture. The air pressure directly affects the spray characteristics, so a slight adjustment helps accommodate the specific Type of paint and conditions being used.

In contrast, turning the fluid adjustment in to the maximum setting may lead to an overly heavy application of paint, risking runs or a poor finish. Switching to a larger spray nozzle might be unnecessary unless you are working with a thicker paint or broad area application and could disrupt the intended spray pattern for the current task. Draining any excess paint is usually not required immediately unless there is a risk of overflow, focusing instead on adjusting the air settings is a more pertinent step after filling the spray gun.
