Recognize Air Intake Issue

What happens here

While operating a paint sprayer, observe for signs that the sprayer is starting to suck air. This typically occurs when the paint level in the bucket is too low for the intake tube to remain fully submerged, leading to an inconsistent spray pattern or the sprayer ceasing to function properly. The video specifically mentions having about half a gallon of paint remaining when this issue began.

Goal: Identify when the paint sprayer is sucking air due to low paint levels.
