SPRAYER CONTROLS
XBOOST™ POWER DIAL / SWITCH
The X-Boost™ power dial / switch adjusts the level of air pressure produced by the
turbine. The X-Boost™ power dial / switch is factory-set at maximum out of the box.
Variable Air Power Control - The FLEXiO model 3500 is equipped with a variable air
power control (1-9).
2-Speed Air Power Control - The FLEXiO model 2500 is equipped with a 2-speed air
power control (high / low).
• 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 CONTROL
The material ow control determines the amount of spray material that is sprayed
from the spray gun.
iSpray Nozzle - The material ow can be adjusted incrementally from 1 (minimum) to
12 (maximum) by turning the adjustable material ow control
Detail Finish Nozzle (3500 only) - Set the material ow by turning the knob on the
trigger of 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.
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).

DETAIL FINISH
Spray performance will depend upon a number of factors: material thickness, air power, spray pattern selected,
and material ow. Testing dierent variations of the control settings will help you achieve the desired results.
