21GM 4700ACB_00071B_02382OPERATING MANUALVERSION 09/2011 ORDER NUMBER DOC 23117305.4 WORKSSpray pattern shapesNo atomization air Too little atomization air Correct amount of atomization airThe spray pattern can be adjusted to suit the object being sprayed using the shaping air regulator. Theillustration below shows the influence of the shaping air regulator on the spraying pattern Other nozzle sizescan be used to obtain larger or smaller spraying patterns.Shaping airclosedShaping air fullyopenNote:The paint output volume can be changed by:- changing the material pressure or- Using a different flat jet nozzle (see chap. 5.4.3 and chap. 8).5.4.1 START-UP FOR SPRAYING AIRCOAT5.4.2 ADJUSTING THE SPRAY PATTERN1. Start up with material supply set to approx. 8 MPa; 80 bar; 1160 psi operating pressure.2. Spray (release locking device and pull trigger) and at the same time, check the atomization.3. Set the fluid pressure on the fluid pump to the point where a good fluid atomization is achieved.4. Open the air pressure regulator for the atomizer air and adjust it so that an optimal atomization isachieved. (The interrelation between spray pattern and atomizer air is shown in the figure below).5. Use the shaping air controller on the gun to adjust the shaping air to atomizer air ratio, until theoptimal spray pattern is achieved.Note:Repeat points 4 and 5 until the optimum spray pattern has been found (iterative process).
