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:Increasepressureordilutecoatingmaterial.Eachpumpconveysacertainquantityinproportiontothesizeofthetip:
The following principle is valid: large tip = low pressure
small tip = high pressure
There is a large range of tips with various spraying angles.

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.
