3. GENERAL INFORMATION
3.1 Compressors and Air Pressures
Choosing an appropriate air compressor that supplies sufficient
air flow ensures the ability to take full advantage of the versatile
spray characteristics of your Grex airbrush. Working pressures can
vary from 4 to 80 psi depending on the type of work and what
textures are desired. Paint viscosity and fluid nozzle opening size
can affect optimal working pressures. In general, thicker and higher
viscosity paints require higher pressures. Thick paints may require
45 psi or higher, while thinner paints may only need 18 to 25 psi.
It is strongly recommended that you use air filters, moisture
traps, and pressure regulators as part of your airbrush system.
Having clean, dry air enables optimal performance, provides
hassle-free maintenance, and prolongs the life of your airbrush.
Note: Use of the siphon aachment requires relatively higher
operating pressures than gravity feed cups.
3.2 Paint Preparation
Your Grex airbrush comes standard with Teflon packings which
allows most paints to be used with the airbrush. This includes, but
is not limited to, food dyes, acrylics, textile paints, makeup,
lacquers, and urethanes.
Proper paint preparation is needed for best performance. Paint
must be reduced using the proper solvent (manufacturer
recommended) and mixed thoroughly. Always filter the paint
through a fine nylon mesh to remove clumps and chunks that can
disrupt consistent spray and block the minute passageways in the
airbrush.
Warning: Always wear proper protective gear and clothing (such
as goggles, respirator, dust mask and gloves). Work in a well
ventilated area, especially when using urethane and enamel based
paints. Follow all instructions that come with your paint, and use
the reducers recommended by the paint manufacturer.
3.3 Airbrush System Setup
Aach any desired accessories, such as moisture traps, filters,
regulators, etc., to your compressor and/or airbrush depending on
your setup. Connect an air hose between the compressor and
airbrush while using the appropriate adapters where necessary.
Refer to Section 8 “Accessories” to learn more about adapters that
may be needed for your system setup. Adjust air pressures
according to paint type and desired spray characteristics. Check for
any air leaks from the compressor and air hose. Then fill the paint
reservoirs or boles with paint when ready to use.

4. GENERAL OPERATION
4.1 Before Each Use
Spray water or appropriate paint solvent through your airbrush to
make sure the airbrush is working properly and to clear out any
pigment residue present. Refer to Section 4.5 “Airbrush Trigger
Operation” for specific instructions on airbrush operation.
4.2 Holding Your Airbrush
There are several options to holding your airbrush for operation. In
the following few figures, we illustrate some of the recommended
methods. Choose the one that allows you to work most naturally
and comfortably.
4.3 Quick-FitTM Needle Caps
All Grex Tritium airbrushes feature our patented Quick-FitTM
needle caps. These caps can be easily removed and installed by
simply aaching them to the magnetic nozzle cap. Each airbrush
includes one Quick-FitTM Standard Needle Cap and one Quick-FitTM
Crown Needle Cap. Both caps are meant to protect the needle tip
from damage, but the crown needle cap is cut away on two opposite
sides to allow spraying of fine lines with the airbrush positioned
close to the work surface.
Note: The rear end of the Pre-set Adjustment Knob also serves as a
convenient magnetic storage for either Quick-FitTM needle caps.

4.4 Installing Paint Reservoirs
Tritium.TG
Your Tritium.TG airbrush comes with three top gravity cups of
varying fluid capacity. Depending on your application, you can
chose to install either one of these cups. Simply securely screw the
threaded base of the cup onto the airbrush. For very minute
amounts of paint, you can forgo the paint cups and just use the
integrated cup.
Tritium.TS
Your Tritium.TS airbrush comes with three reservoirs of varying
fluid capacity - two side gravity cups and one side siphon
aachment with bole. Depending on your application, you can
choose to install either one of these reservoirs and they can be
installed on either the left or right hand side of the airbrush. Side
reservoirs can also be adjusted to be used at any angle.

4.5 Airbrush Trigger Operation
In a double action pistol style trigger airbrush, the trigger controls
both the air flow through the airbrush and the paint volume
sprayed. Pulling the trigger back to the halfway point opens the air
valve at the boom of the airbrush and allows air to flow through.
Further pulling back on the trigger pulls the fluid needle back away
from the fluid nozzle allowing paint to be sprayed. As the trigger
continues to be pulled back, the nozzle opening becomes larger
which allows more paint to be sprayed to create a wider spray
paern.
4.6 Spray Paern Adjustments
Paint sprayed from an airbrush exits from the nozzle in the form of
a cone. As the needle of the airbrush is pulled back away from the
nozzle, the nozzle opening is increased allowing more paint to be
sprayed resulting in a wider cone. Depending on where the work
surface intersects this cone, a different spray width is achieved. So,
line widths produced by the airbrush are controlled by a combina-
tion of adjusting the distance the airbrush is held from the work
surface and adjusting the amount of paint allowed to spray.

4.6 Spray Paern Adjustments <continued>
Fine Line Spraying
To spray a fine line, position your airbrush close to your work
surface and control your airbrush such that a minimal amount of
paint is sprayed. The closer the airbrush is to the work surface, the
finer the line that is created. An extremely fine line can be obtained
by using the Crown Needle Cap and positioning your airbrush even
closer to the surface. See page 7, Figure 4H for reference.
Wide Line and Background Spraying
To create wider lines and background spraying, position your
airbrush further from the work surface and control the airbrush to
release more paint. Increasing the air pressure, the distance of the
airbrush from the surface, and the amount of paint sprayed will
further increase spray widths. See page 7, Figure 4G for reference.
Stippling
Stippling is the technique of using small dots to simulate varying
degrees of solidity or shading. There are many methods for creating
stippling effects with an airbrush, but one way this can be achieved
is by lowering the air pressure to between 5 and 15 psi and pumping
the trigger. Lower air pressures will usually produce courser
stipples whereas higher air pressures will provide finer stipples.
Note that paint viscosity will also affect the stippling texture.
4.7 Pre-set Knob Adjustments
To help produce constant line widths, your Grex airbrush comes
standard with a Pre-Set Knob on the end of the rear handle cap. A
set amount of paint is sprayed by limiting how far the trigger can be
pulled back. Turning the knob clockwise reduces how far the trigger
can move to help produce consistent fine lines. Turning the knob
counter clockwise allows the trigger to move further back to help
produce consistent wider lines. Fully turning the knob clockwise
will prohibit trigger movement and prevent any spraying. Fully
turning the knob counter clockwise will allow the full range of
trigger action and deactivate the Pre-set knob
capabilties.
