Air and Material Controls
Spray performance will depend upon a number of
factors: material thickness, air power, spray pattern
selected, and material flow. Testing different
variations of the control settings will help you
achieve the desired results. See descriptions and
suggested Power and Material Settings Guide below
to help with your project.
X-Boost™ Power Dial
The X-Boost™ power dial adjusts the level of air
pressure produced by the turbine. The X-Boost™
power dial is factory-set at maximum out of the box.
• A high air power level will result in faster
coverage and a smoother finish with thicker
materials.
• Lowering the air power will result in larger
drops of material being sprayed from the gun,
and will create a slightly rougher finish.
• Use the arrow (a) to set power level with the
three markings (b) on the dial. Thinnest section
= low. Middle section = medium. Thickest
section = high.

Tip: The thicker the material you are spraying, the
higher the air pressure you will need.
Tip: For fine-finish work with thinner materials, you
may want to decrease the air pressure. Spraying
a thinner material at high air pressure will result in
more overspray. Overspray is sprayed material that
does not stick to the spray surface and bounces
back.
Material Flow Control
The material flow control determines the amount of
spray material that is sprayed from the spray gun.
• For thicker materials, it is recommended that
you start with the highest material flow setting
and then gradually decrease the flow to suit
your particular spraying needs.
• For thinner materials, it is recommended that
you start with a low material flow setting, and
then gradually increase the flow to suit your
particular spraying needs.
• The higher the flow setting, the quicker you will
have to work in order to avoid drips and sags in
your spray pattern.
Set the material flow by turning the red knob on the
trigger of the spray gun.
Tip: Spraying with the control set too high will
result in a spray pattern that runs and sags (too
much material).
Tip: Spraying with the control set too low will result
in a spray pattern that does not cover (not enough
material).
Tip: To ensure desired results are achieved with the
controls, test your spray pattern on the spray poster
or a scrap piece of wood or cardboard.
