Understand the operational modes and pressure settings for effective spraying.
5.1 Powering On and Priming:
- Konektatu korronte-kablea lurreko hartune elektriko batera.
- Set the function switch to the "Prime" mode. This mode is used to pre-fill the paint and relieve pressure.
- Allow the system to draw paint until it flows smoothly through the return hose into the paint bucket.
- Once primed, switch the function to "Spray" mode.

Image 5.1: Function Switch. This image shows the function switch used to toggle between 'Prime' (pre-fill paint, pressure relief) and 'Spray' (paint application) modes.
5.2 Adjusting Pressure:
The working pressure can be adjusted in 5 levels using the pressure regulator dial.
- Start with a lower pressure setting and gradually increase until the desired spray pattern is achieved.
- Higher viscosity paints typically require higher pressure settings.
