9. Adjusting the desired Spray Setting
Three different spray jet settings can be chosen on the spray gun, depending on the
application and target object.
WARNING! Danger of injury! Never pull the trigger guard while adjusting
the air cap.
With the union nut (fig. 5, 1) slightly unscrewed, turn the air cap (2) to the desired spray
setting position (arrow). Then tighten the union nut.

11. Spray Technique
The spray result depends heavily on the smoothness and cleanliness of the surface to be
•
sprayed. Therefore the surface should be carefully prepared and kept free of dust.
Cover all surfaces not to be sprayed.
•
Cover screw threads or similar parts of the target object.
•
It is advisable to test the spray gun on cardboard or a similar surface to find the correct
•
setting.
Important:
Begin spraying outside of the target area and avoid interruptions inside the
target area.
•
Correct (Fig. 7a)
Be sure to hold the spray gun at an even distance of approx. 5 - 15 cm
to the target object.
•
Incorrect (Fig. 7b)
Heavy spray fog build-up, uneven surface quality.
Move the spray gun evenly cross-wise or up-and-down, depending on the spray pattern
•
setting.
An even movement of the spray gun results in an even surface quality.
•
When coating material builds up on the nozzle (A) and air cap (B) (Fig. 8), clean both
•
parts with a solvent or water.
12. Interruption of Work till 4 Hours
