Spray Technique
Be sure to follow the Pressure Relief Procedure when shutting the unit off for any purpose.
This procedure relieves the pressure from the spray hose and the gun. Watch the pressure gauge ––> 0 bar
Danger
Be sure that the paint hose is free of kinks and clear of objects with sharp cutting edges.

It is best to practise on cardboard or a similar surface first of all, in order to check the spray pattern and become accustomed to
using the spray gun.
If the paint sprays evenly, as shown in fig. 16 A, all the setting must be correct.
i
If the paint looks stripy after spraying, as shown in fig. 16 B, gradually increase the pressure, or dilute more in 5%
steps (please note the maximum amount of thinner stipulated by manufacturer.)
•
The key to obtaining a high quality result is even coating of the entire surface.
Keep your arm moving at a constant speed and keep the spray gun at a constant distance from the surface. The best spraying
distance is approx. 20 to 25 cm between the spray nozzle and the surface. (Fig. 17, A)
•
Keep the spray gun at right angles to the surface. This means moving your entire arm back and forth rather than just flexing your
wrist. (Fig. 17, B)
•
Keep the spray gun perpendicular to the surface, otherwise one end of the pattern will be thicker than the other. (Fig. 17, C)
•
Trigger gun after starting the stroke. Release the trigger before ending the stroke. (Fig. 17, D) The spray gun should be moving when the
trigger is pulled and released. Overlap each stroke by about 30%. This will ensure an even coating.
During operation the pump switches on and off continuously, in order to regulate the pressure.
i
This is normal and is not a malfunction.
Unclogging the Spray nozzle
If the spray pattern becomes distorted or stops completely while the gun is triggered, follow these steps.
Do not attempt to unclog or clean the nozzle with your finger. High pressure fluid can cause injection injury.
Danger
1. Release the trigger and secure the gun. Rotate the reversible nozzle arrow 180º so that the point of the arrow is toward the
rear of the gun. (Fig. 18).
