Start up with material supply set to approx. 8 MPa; 80 bar; 1160 psi operating pressure.2. Spray (release trigger safety catch and pull trigger) and check the atomisation.3. Set the fluid pressure on the material supply to the point where a further increase in fluid pressure wouldsignificantly improve fluid atomization.4. Open air pressure regulator for the atomizer air and adjust so as to achieve optimal atomization. Theinterrelation between spray pattern and atomizer air is shown in the figure below.5. With the air adjustment on the gun, the ratio form adjustment to atomization until the optimum spraypattern is achieved.Note:Repeat point 4 and 5 until the optimum spray pattern is reached (process iterative).Spray patternno atomizing air too little atomizing air correct amount of atomizing airInfluence of the air adjustment on the spray pattern shapeThe spray pattern can be adjusted to suit the object being sprayed using the air adjustment. The illustrationbelow shows the influence of the shaping air regulator on the spraying pattern.Other nozzle sizes can be used to obtain larger or smaller spraying patterns.Closedair adjustmentCompletely openedair adjustmentNote:The paint output volume can be changed by:• Changing the material pressure or• using a different flat jet nozzle (see chapter 9).
