ssemble irbrush to Compressor
Connect the air hose to the compressor
and airbrush, then turn on the compressor.
If using an
irblade
compressor, adjust
®
the pressure to between 20 and 30 psi.
Listen for any air leaks in the compressor
or air hose fittings. Point the airbrush away
from you and press down on the trigger
(#13) to start the flow of air through the
airbrush. Place a small amount of solvent
or cleaner into the cup and pull back on the
trigger. This will clean out any residual
factory testing material that may still be in
the airbrush.
Mix Paint and Fill the Removable Cup
Follow
the
paint
manufacturer's
instructions and thin the paint with its
proper solvent. Filter it through a nylon
mesh strainer. It is best to "over-reduce" or
prepare the paint relatively thin and make
continuous passes across your work to
achieve the desired shade. This will also
decrease paint buildup on the needle and
cleaning time. The D GR features a
removable cup. Depending on the amount
of paint you wish to spray, use the
standard 1/3 oz. (9 cc) cup or select an
optional 1/4 oz. (7 cc) or 1/2 oz. (14 cc) cup.
For small amounts of material, simply
remove the cup and fill the cup socket,
which will give you best visibility for close-
up work.
GENER L OPER TION
The D GR is a double action airbrush for
fine control. Push the trigger down for air
flow and pull the trigger back for paint
flow. For best results during spraying, keep
air flow even when you have stopped paint
flow.
ir Pressure Range
Working pressures vary between 20 and 50
psi, depending on what type of work is
being done, what spray characteristics are
desired, and paint viscosity. Generally,
thicker paints or higher paint flow will
require higher pressures.
Spraying Fine Lines and Detail
To spray a fine line or detail, press the
trigger down for air flow and pull it back
slightly for paint flow while moving the
airbrush very close to the surface. Control
the thickness of the line by adjusting the
distance between the airbrush and the
surface and by adjusting the amount of
paint flow with the trigger.
line can be achieved by carefully removing
the crown cap (#1) and moving the
airbrush closer to the surface.
NOTE: The needle and nozzle are very
finely machined.
of the needle can result in an uneven
pattern. The crown cap protects the
needle yet still allows fine lines to be
sprayed.
Wide Lines, Fades, and
Background Spraying
For wider lines, fades, and background
spraying, pull the trigger further back for
more paint flow. Increase the distance
between the airbrush and artwork up to six
inches to control the line width. Increasing
the air pressure will also affect the spray
width. The D GR will spray a background
width of approximately two inches. Speed
of movement controls the density of the
color and fading effects.
Spraying Lines Without Heavy Ends
To spray a fine or wide line without heavy
ends, start moving the airbrush with the
trigger pushed down for air. Then pull the
trigger back for paint flow at the beginning
of the line and stop paint flow at the end,
n even finer
but continue the motion of the airbrush.
