Air and Material Controls
Spray performance will depend upon a number of
factors: material thickness, spray pattern selected,
material volume, and air pressure. With any type
of air-assisted spraying, desired spray results will
be achieved through some trial and error while
adjusting some or all of these variables.
Review these pages to learn about the spray controls
and how they can be used to acheive the desired
spray results.
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 nish 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 nish.

Tip: The thicker the material you are spraying, the
higher the turbine
power
you will need.
Tip: For ne-nish work with thinner materials, you
may want to decrease the air
power
. Spraying a
thinner material at high air
power
will result in more
overspray. Overspray is sprayed material that does
not stick to the spray surface and bounces back.
Material Flow Adjustment
The material ow adjustment controls 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 ow setting
and then gradually decrease the ow to suit
your particular spraying needs.
• For thinner materials, it is recommended that
you start with a low material ow setting, and
then gradually increase the ow to suit your
particular spraying needs.
• The higher the ow setting, the quicker you will
have to work in order to avoid drips and sags in
your spray pattern.
Set the material volume by turning the 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.
