How To Set Up An Airless Sprayer | Paint Sprayer Tips
What happens here
Before introducing paint, ensure the sprayer's on/off switch is in the 'off' position before plugging it into a power source. Submerge both the intake tube (the one with the rock guard) and the prime tube into a bucket of clean water. Turn the pressure adjustment knob to its lowest setting. Rotate the prime/spray valve to the 'prime' position. Turn the sprayer 'on' and allow it to cycle water through the system. Observe the prime tube for air bubbles; continue running until a steady, bubble-free stream of water flows from the prime tube, indicating all air has been expelled. Then, switch the prime/spray valve to the 'spray' position to allow the system to build pressure, and then turn it back to 'prime' while holding the prime tube securely in the water to release the pressure safely.
Goal: Prime the airless sprayer with clean water to purge all air from the system before introducing paint, ensuring a smooth and consistent paint flow.
