Spray Technique

•
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.
•
It is advisable to test the spray gun on cardboard or a similar surface to find the
correct setting.
Important: Begin spraying outside of the target area and avoid interruptions inside
the target area.
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.
Fig. 9 a: CORRECT Even distance to the object.
Fig. 9 b: INCORRECT Uneven distance causes uneven coating.
•
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.
•
When coating material builds up on the nozzle and air cap, clean both parts with a
solvent or water.

Interruption of Work till 4 Hours

•
Turn the machine off.
•
Insert the spray gun into the gun holder.
•
When processing 2-component varnishes, clean the device immediately.
Taking Out of Operation and Cleaning
Proper cleaning is the prerequisite for problem-free operation of the paint application
device. No warranty claims are accepted in case of improper or no cleaning.
1) Turn the machine off. Vent the container in case of longer breaks and after the work
has been terminated. This can be done by briefly turning open and then closing the
container or by pulling the trigger guard and letting the paint into the original paint
container.
2) Divide the spray gun. Press the hook (Fig. 5 "click") slightly downwards. Turn the gun
front part and gun rear part against each other.
3) Unscrew the container. Empty any remaining coating material back into the material
tin.
4) Preclean the container and feed tube with a brush. Clean the ventilating bore
(Fig. 12, C).
5) Pour solvent or water into the container. Screw the container back on.
Use only solvents with a flashpoint over 21 °C.
6) Assemble the gun again (Fig. 5).
7) Turn on the machine and spray the solvent or water into a container or a cloth.
8) Repeat the above procedure until the solvent or water emerging from the nozzle is
clear.
