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 wouldsignificantly improve fluid atomization.4. Now open AirCoat-air on the atomizing air regulator and set.5. Adjust the pressure to get the optimum spraying finish. Relation between spray patternand atomizing air see illustration. Set the minimum air pressure necessary to achievethe best possible spray pattern.Note:Repeat point 4 and 5 until the optimum spray pattern is reachedSpray patternsB_00071no atomizing air too little atomizing air correct amount of atomizing air5.4.2 ADJUSTING THE SPRAY PATTERNThe spray pattern can be adjusted to suit the object Being sprayed using the shaping airregulator. The illustration below shows the influence of the shaping air regulator on thespraying pattern.Other tip sizes can be used to obtain larger or smaller spraying patterns.Shaping air fullyclosedShaping air fullyopenNoteThe paint output volume can be changed by:Changing the material pressure.• Fitting another flat jet nozzle.
