Spraying
Start Notice:
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.
Controls
Air Pressure Control Dial
The air pressure control dial adjusts the level of air pressure
produced by the turbine. The air pressure control dial is factory-
set at maximum out of the box.
• A high air pressure level will result in a smoother finish.
• Lowering the air pressure will result in larger drops of
material being sprayed from the gun, and will create a
slightly rougher finish.
+ -
Tip: The thicker the material you are spraying, the higher the
turbine 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 Adjustment
The material flow 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 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 volume by turning the knob on the trigger
of the spray gun.
Tip: Spraying with the knob set too high will result in a
spray pattern that runs and sags (too much material).
Tip: Spraying with the regulator set too low will result in a
spray pattern that does not cover (not enough material).
Adjust Spray Width - white gun only
The adjustment ring on the white spray gun determines the
width of the spray pattern.
Adjustment ring
wide
pattern
 For coating large surfaces
 Use higher air pressure
 Use higher material volume
narrow
(round)
pattern
 For coating smaller areas,
corners and edges
 Use lower air pressure
 Use lower material volume
Adjust Spray Shape - both guns
The spray pattern shape is adjusted by turning the
ears of the air cap to either the vertical, horizontal, or
diagonal positions. The positions of the air cap and the
corresponding spray pattern shapes are illustrated below.
Test each pattern and use whichever pattern is suitable for
your application.
neveR trigger the gun while adjusting the
ears on the air cap. neveR point the spray gun
at any part of the body.

*note: The air cap can be set diagonally on the yellow spray
gun only. To achieve a round pattern with the white spray
gun, see “Adjusting the Spray Width”, previous column.
