13. Appendix

13.1 Selection of tip

To achieve faultless and rational working, the selection of the tip is of the greatest importance.

In many cases the correct tip can only be determined by means of a spraying test.

Some rules for this:

The spray jet must be even.

If streaks appear in the spray jet the spraying pressure is either too low or the viscosity of the coating material to high.

Remedy:Increasepressureordilutecoatingmaterial.Eachpumpconveysacertainquantityinproportiontothesizeofthetip:

The following principle is valid: large tip = low pressure

small tip = high pressure

There is a large range of tips with various spraying angles.

13.2 Servicing and cleaning of Airless hard-metal tips

Standard tips

Ifadifferenttiptypehasbeentted,thencleanitaccordingtomanufacturer’sinstructions.

The tip has a bore processed with the greatest precision. Careful handling is necessary to achieve long durability. Do not forget the fact

thatthehard-metalinsertisbrittle!Neverthrowthetiporhandlewithsharpmetalobjects.

The following points must be observed to keep the tip clean and ready for use:

 1. Turnthereliefvalvehandlefullycounterclockwise(kCirculation).

2. Switch off the gasoline engine.

3. Dismount the tip from the spray gun.

4. Place tip in an appropriate cleaning agent until all coating material residue is dissolved.

5. If there is pressure air, blow out tip.

 6. Removeanyresiduebymeansofasharpwoodenrod(toothpick).

7. Check the tip with the help of a magnifying glass and, if necessary, repeat points 4 to 6.
