• Connect the compressed air hose of your compressor to the hose
connection (7) on the airbrush gun.
• Fill the paint cup with paint, diluted as required. The paint should
be considerably more diluted than when used for painting with a
normal brush. It should have a milky consistency.
• Switch the compressor on.
• Set a working pressure of approximately 2 bar on the compres-
sor. This is the normal value. The correct working pressure
depends on the consistency of the paint, the nozzle size and the
airbrush gun itself.
• Before you start spraying the object you want to paint, it is advis-
able to do a test on a piece of cardboard or sheet metal in order
to set the appropriate working pressure on your compressor and
to test the paint consistency. You can find the recommended
working pressures for the different airbrush guns in the technical
data section.
• Set the working pressure to quite a high level at first. Then do a
spray test and keep reducing the working pressure until the
spraying result is no longer sharp. Then raise the working pres-
sure again by about 0.5 bar.
• The lower you set the working pressure, the narrower the spray
becomes. If the working pressure is too low or there is too much
paint, this causes spotting.
• When spraying, the amount of paint and the air supply are con-
trolled at the same time by the trigger lever (4) (double-action
principle).
• The compressed air flows out as soon as you press the trigger
lever (4). The further back you pull the trigger lever (4), the more
paint is fed into the spray nozzle (3).
• With the adjustment screw (9) (not included with the AB 430 mod-
el), you can restrict the distance that the needle moves back-
wards and thus limit the amount of paint. This is particularly use-
ful if you want to keep the width of the spray constant (e.g. for
lines).
