Product overview
1.2 Short description
The spray gun is intended for surface coating. Compressed air is used to apply material. The material to be atomized is fed via flow cups. The spray gun is handheld.
Use a suitable nozzle set with air cap,
depending on the requirement Ä 6.3
The following factors influence the spray jet and the result:
Alignment of the air cap Ä 6.5 “Alignment of the air cap”
Material flow Ä 5 “Commissioning”
Air pressure
Horn air pressure
The spray gun uses a self-adjusting needle package. The needle gland automatically adjusts for the material-related wear of the needle gland. In addition, the needle packing can be readjusted mechanically.

6.1 Safety recommendations
WARNING!
Danger of explosion due to chemical reactions
Material, halogenated hydrocarbon-based rinsing agent or cleaning agent can chemically react with aluminum components of the product. Chemical reactions can cause explosions. Serious injuries and death can be the consequence.
– Only use rinsing agents and cleaning agents that do not contain any halogenated hydrocarbons.
NOTICE!
Material damage due to dried material residues
If material residues dry in the product, that can harm components.
– Rinse product immediately after each use.
6.2 Checks

Check air connection for correct seat and leaks.
Check air car for cleanliness.
Check nozzle for cleanliness.
6.3 Selecting air cap
You can convert the spray gun for various uses by swapping the air cap.
Air cap AL
The air cap AL is used for solvent-based coating materials (1-component paints and
2-component paints) and water-based ones.
It is used for application of fillers, basecoats and topcoats. If used with a hardened nozzle, coating materials with abrasive additives (coating materials containing zinc and aluminum) can be applied.
Air cap EL
The air cap EL is used for solvent-based coating materials (1-component paints and
2-component paints) and water-based ones, if higher outflow rates are required.
Air cap GL
The air cap GL is used for thick, high viscosity coating materials. It is used for application at a high outflow rate.
