mixture of air and the coating material. It is recommended to adjust the mixture jet so as to obtain possibly minute particles of the
coating material, which will guarantee a better spread of the coating material on the surface.
Work with the spray gun
Operating the spray gun, maintain a distance between the spray gun nozzle mouth and the coated surface within the range of
10 to 15 cm. Try to lead the spray gun nozzle mouth perpendicularly to the coated surface. Avoid curved movements, since they
will cause uneven spreading of the coating material. It is recommended to apply several thin layers rather than a single thick
coating.
Air flow adjustment
Depending on the type of the coating material, adjust the proper quantity of the compressed air turning the air pressure adjustment
knob.
Replacement of the nozzle
Make sure the whole nozzle assembly is replaced. The nozzle assembly consists of a coating material nozzle, a nozzle needle
and an air nozzle.
Nozzle needle sealing
During work, check the nozzle needle sealing for tightness. If the sealing is significantly worn-out, it must be replaced during a
periodical inspection of the spray gun, using an open-ended spanned to disassembly the sealing unit.
Cleaning and maintenance
Once the work has concluded, disconnect the spray gun from the compressed air system and remove the coating material
remaining in the tank. Clean the tank thoroughly of the coating material residues.
Clean thoroughly the whole route of the coating material. Careless cleaning will impair the parameters of the coating material jet.
The air nozzle should be cleaned with a brush soaked in a solvent. Never should the spray gun be completely immersed in the
solvent.
Never should clogged openings be cleaned with hard objects, since even slight internal damage may affect adversely the spray
jet parameters.
Once the spray gun has been cleaned, the movable elements of the sealing must be coated with a small quantity of a lubricant.
The coating material nozzle should be tightened so as to avoid leakage, and guarantee a fluid movement of the nozzle needle.
