Operation
After each change in the spray pressure it is necessary to reset the pressure
and metering monitoring. If the pointer of the contact manometer does not
move or only moves insufficiently, the system must not be put into operation
due to the risk of erroneous mixing!
5.2.3 Tips for good coatings
➤
Hold the spray gun at a right angle (90°) to the
surface to be coated. As soon as you hold the
spray gun at a different angle, the coating will
become uneven and patchy (see Fig. 22).
➤
Move the spray gun with the arm and not with
the wrist.
➤
Move the spray gun prior to activating the trig-
ger. In this way you will achieve a faultless, soft
and smooth overlapping of the spray jet and
avoid an excessively thick material application
at the start of the coating process.
➤
Ensure an even speed and guide the spray
gun parallel to the coating surface.
Weaving with the spray gun leads to an uneven
coating (see Fig. 23).
➤
Release the trigger before stopping the move-
ment.
➤
Change the spray nozzle before this becomes
worn.

Worn nozzles lead to excessively high material consumption and adversely
affect the quality of the coating.
5.3 Flushing
When interrupting work you should flush all components that had contact with
the mixed material, within the potlife specified by the manufacturer.
1.
Close and lock the spray gun.
2.
Set the levers at the mixing unit to “Flush“.
3.
Keep spraying the material mix in the unit into a collecting vessel, until
clean flushing agent starts flowing out.
Open and close the flushing levers multiple times in alternation during flush-
ing, in order to ensure that each component is flushed through separately.
Finally, flush with both levers in the flushing position.
4.
Close and lock the spray gun.
The section between mixing unit and spray gun has been cleaned. The materi-
al in the section between material inlet and mixing unit may remain in the unit,
because no mixing will take place.
