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 fitted, 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 knob three revolutions to the left
(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.
