How To Use a Paint Sprayer.
What happens here
Most airless sprayers, regardless of brand, will have three main controls: a power switch, a pressure dial, and a prime valve. Locate the power switch, usually on the body of the sprayer. Identify the pressure dial, which adjusts the paint pressure up or down. Find the prime valve, often a small lever located on the lower housing. This valve typically has two positions: 'down' for prime (fluid goes through the prime hose) and 'up' for spray (fluid goes to the gun). For initial setup, ensure the prime valve is in the 'down' position.
Goal: Understand the main operational controls of the airless sprayer.
