Purge Extension & Final Pressure Check

How To Use a Paint Sprayer.
What happens here
After attaching the extension, it will still contain water or protector fluid from the initial priming. Point the spray gun into the discard bucket. With the prime valve in the 'spray' position (upwards), depress the trigger to spray out all the remaining water/protector until a consistent stream of paint emerges. Avoid spraying directly at the bucket wall to prevent splash-back; instead, spray downwards, allowing the fluid to curve along the inner wall. Once paint flows consistently, indicating no more air or foreign fluids, release the trigger. Perform a final check: ensure there are no leaks around any hose connections, confirm the product is flowing correctly, and verify the pressure is set to your desired level. Now, attach the appropriate spray tip, and your sprayer is ready for use.
Goal: Purge all remaining water or protector from the extension into the discard bucket, then activate the spray gun to ensure proper paint flow and pressure.
