Starting Up 1. Learn how to operate the control valve. The control valve sets the prime or pressure position as well as the spraying pressure. When the valve is fully counter-clockwise the unit is in the prime position. As the control valve is turned clockwise, the unit’s output pressure to the gun is gradually increased until the control valve is fully clockwise and the unit is at it’s maximum output pressure of 2500 psi. This will fully atomize any stain or paint without needing to dilu
