•The automatic gun GA 250AL or GA 400AL is controlled by way of the control air (B).
•The control piston on the valve stem in the housing (C) of the spray gun GA 250AL or GA 400AL has pressure applied to it and thereby opens the paint duct to the flat jet nozzle (F).
•Closure takes place with the compression spring (H) after the pressure drop of the control air (B) valve.
•The set of seals (I) prevents that material can flow into the housing (C).
•Secure the gun: Remove the air hose from the control air connection (B) on the spray gun.
