What happens here

To prepare the sprayer for painting, it must first be primed with clean water. Place the uptake tube (the suction tube that draws liquid) into a bucket filled with clean water. Ensure the prime knob is pushed all the way down to the 'prime' position. Turn the sprayer on using the on/off switch. Allow the sprayer to run until clean water begins to come out of the purge hose, indicating that all air has been removed from the internal system. Once clean water flows consistently, switch the prime knob up to the 'spray' position to build pressure, and then turn off the sprayer. The operator suggests setting the pressure to approximately 2 o'clock, which is around 2200 PSI, a suitable setting for exterior paint applications.

Goal: Purge air from the sprayer system using clean water and build initial pressure.
