Spend some time practising on cardboard or a similar surface in order
to determine the right ow rate of paint and air for the best spray
pattern. Detailed information about these settings can be found in
chapter 11-12.
11. Selecting the Spray Setting
WARNING! DANGER OF INJURY! Never pull the trigger guard while adjusting
the air cap.
With the air cap ring (Fig. 4, 1) slightly unscrewed, turn the air cap (Fig. 4, 2) to the desired
spray setting position. Then tighten the air cap ring.
Fig. 5 A = vertical at jet  for large areas; side to side motion
Fig. 5 B = horizontal at jet  for large areas; up and down motion
Fig. 5 C = circular jet  for corners, edges and hard-to-reach surfaces
12. Adjusting the Material Volume
Set the material volume by turning the material volume adjuster on the rear of the spray
gun (Fig. 6).
+ turn to the left  higher material volume
– turn to the right  lower material volume
13. Spray Technique
i
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.
i
Important: Start at the edge of the area to be sprayed. Start the spray
movement rst of all, and then press the trigger. Avoid interruptions
within the area to be sprayed.
•
The spray movement should come from the arm, not just from the wrist. This ensures that
a uniform distance is maintained between the spray gun and the spray surface during
the spray operation. Select a distance of 5 - 15 cm, depending on the desired spray jet
width. When you are using interior wall paint, the distance should be about 20-30 cm.
