12. Adjusting the Material Volume
The volume of material can be set by turning the material volume control (Fig. 7, 1) in
steps from 1 (minimum) to 12 (maximum).
13. Setting the Amount of Air (Fig. 8)
i
Depending on the viscosity of the material to be sprayed and the nish of
the object to be coated, it may be advisable to vary the amount of air. Very
low viscosity materials, such as watery glazes do not have to be atomised
with the maximum amount of air. In this case it is advisable to reduce
the amount of air and thus minimize the spray vapour.
This also applies for the use of the Detail and Corner&Reach spray attachment
(accessory).
Slide the air volume regulator (g. 8, 1) into the desired position:
thin paint
Level I
thick paint (e.g. interior wall paint)
Level II
14. 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
(approx. one stirring rod in length).
Fig. 9 A/ 9 B: CORRECT Even distance to the object.
Fig. 9 C:
INCORRECT An uneven distance will result in uneven paint
application.
•
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.
