2. CONTROL OF THE AMOUNT OF THE MATERIAL
2.1 AIR PLUS SPRAY SCHULZ
De ne the amount of the material, turning the regulator of the air intake of the gun ( gure 9.6 and 9.7):
+ turning to the right greater volume of material
- turning to the left smaller volume of material
3. SPRAYING TECHNIQUES
The result of the work depends directly on the  nishing and cleaning degree of the surface to be painted. Prepare
the region carefully leaving it free of dust or dirt;
Protect the surfaces that will not be painted;
Perform uniform motion, by doing it you will get better quality  nishing;
Clean with solvent or with water the  nishing material waste that eventually accumulates in the spraying nozzle
or the paint regulator;
The spraying motion must start from the arm and not form the hand joint. With this, you will guarantee the dis-
tance between the equipment and the working area, keeping it constant. Depending on the width of the spraying
jet, keep a distance from 5 to 15 cm;
The Figure 9.8A – CORRECT – shows the correct distance with a quality and homogeneous  nishing.
The Figure 9.8B – WRONG – shows an uneven distance, a surface with a lower and not homogeneous  nishing.
