24APPENDIX PS 3.2112 APPENDIX12.1 SELECTION OF TIPTo achieve faultless and rational working, the selection of thetip is of the greatest importance.In many cases the correct tip can only be determined by meansof a spraying test.SOME RULES FOR THIS:The spray jet must be even.If streaks appear in the spray jet the spraying pressure is eithertoo low or the viscosity of the coating material to high.REMEDY: Increase pressure or dilute coating material. Eachpump conveys a certain quantity in proportion to the size ofthe tip:The following principle is valid: large tip = low pressuresmall tip = high pressureThere is a large range of tips with various spraying angles.12.2 SERVICING AND CLEANING OF AIRLESSHARD-METAL TIPSSTANDARD TIPSIf a different tip type has been fitted, then clean it according tomanufacturer’s instructions.The tip has a bore processed with the greatest precision. Carefulhandling is necessary to achieve long durability. Do not forgetthe fact that the hard-metal insert is brittle! Never throw the tipor handle with sharp metal objects.The following points must be observed to keep the tipclean and ready for use:1. Turn the relief valve handle fully counterclockwise (kCirculation).2. Remove the tip from the spray gun.3. Place tip in an appropriate cleaning agent until all coatingmaterial residue is dissolved.4. If there is high-pressure air available, blow out tip.5. Remove any residue by means of a sharp wooden rod(toothpick).6. Check the tip with the help of a magnifying glass and, ifnecessary, repeat points 3 to 5.
