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.

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 handle fully counterclockwise (
Circulation).
2.
Remove the tip from the spray gun.
3.
Place tip in an appropriate cleaning agent until all
coating material 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, if
necessary, repeat points 3 to 5.
