21GM 4600ACB_00071B_02262OPERATING MANUALEDITION 02/2008 Part No. DOC3948615.4 WORKS5.4.1 START-UP FOR SPRAYING AIRCOAT1. Start up with material supply set to approx. 8 MPa; 80 bar; 1160 psi operatingpressure.2. Spray (release trigger safety catch and pull trigger) and check the atomisation.3. Set the fluid pressure to the point where a further increase in fluid pressure wouldsignifi cantly improve fluid atomization.4. Open air pressure controller for the atomizer air and adjust so as to achieve optimalatomization. (The interrelation between spray pattern and atomizer air is shown in thefigure below).5. Adjust the pressure to get the optimum spraying finish. Relation between spray patternand shaping air see illustration.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 air5.4.2 ADJUSTING THE SPRAY PATTERNThe spray pattern can be adjusted to suit the object being sprayed using the fan air regula-tor. The illustration below shows the influence of the shaping air regulator on the sprayingpattern.Other nozzle sizes can be used to obtain larger or smaller spraying patterns.Shaping airfully closedShaping airfully openNoteThe paint output volume can be changed by:• Changing the material pressure or• Fitting another flat jet nozzle (see chap. 5.4.3 and chap. 9).
