electrical shock and the injury to
persons, read and understand all
instructions included in this manual. Be
familiar with the controls and proper
usage of the equipment.
Grounding Instructions
This product must be grounded. In the event of an
electrical short circuit, grounding reduces the risk
of electric shock by providing an escape wire for
the electric current. This product is equipped with a
cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
WARNING - Improper installation of
the grounding plug can result in a risk
of electric shock.
If repair or replacement of the cord or plug is
necessary, do not connect the green grounding wire
to either at blade terminal. The wire with insulation
having a green outer surface with or without yellow
stripes is the grounding wire and must be connected
to the grounding pin.
Check with a qualied electrician or serviceman
if the grounding instructions are not completely
understood, or if you are in doubt as to whether the
product is properly grounded. Do not modify the
plug provided. If the plug will not t the outlet, have
the proper outlet installed by a qualied electrician.
This product is for use on a nominal 120 volt
circuit and has a grounding plug that looks like
the plug illustrated below. Make sure that the
product is connected to an outlet having the same
conguration as the plug. No adapter should be

Important Electrical
Information
Use only a 3-wire extension cord that has a 3-blade
grounding plug and a 3-slot receptacle that will
accept the plug on the product. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough
to carry the current your product will draw. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. A 14
gauge or 12 gauge cord is recommended. If an
extension cord is to be used outdoors, it must be
marked with the sux W-A after the cord type
designation. For example, a designation of SJTW-A
would indicate that the cord would be appropriate
for outdoor use.
IMPORTANT:
for indoor/outdoor use ONLY with materials
having ashpoint above 70ºF (21ºC).

outdoor surfaces. Sprays
all un-thinned materials
including un-thinned latex.
Detail Finish Nozzle:
FLEXiO sprayer model
590 only. Ideal for detail
projects and ner nishes.
It is designed for spraying
thinner materials, such as
oil based stains and paints.
The Detail Finish nozzle
leaves a smoother nish.
English
Material Preparation
Note: Material to be sprayed may need to be strained
to remove any impurities in the paint which may enter
and clog the system. Impurities in the paint will give
poor performance and a poor finish.
Note: Only thin the material if absolutely necessary
to improve spray performance. Optimal spray
performance should be acheived simply by adjusting
the various controls on the unit.
To Prepare the Material:
1. Stir the spraying material thoroughly.
2. Unscrew the cup from the nozzle.
3. After the material has been properly thinned and
strained, ll the container to desired level.
Note: Model 590 only. Use the included paper
funnels in order to more easily fill the cup.
Thinning the material:
For certain spraying situations or desired nishes,
thinning the material may be desired. It is not necessary
for most materials when used with the iSpray nozzle.
For use with the Detail Finish nozzle thinning may be
needed to acheive a ner nish. Make sure you adjust
the X-Boost™ and Material ow settings for your specic
material needs.
If thinning is necessary, use the proper solvent as
specied by the material manufacturer. Never exceed
the thinning advice given by the coating manufacturer.
FLEXiO model 590 sprayers come with a thinning
accessory that can be used to accurately thin spray
material. Refer to the included instruction sheet.
Do not thin with materials that have
a ashpoint below 70°F (21°C). The
material ashpoint should be shown on
the material container.
Spray performance will depend upon a number of
factors: material thickness, spray pattern selected,
and material ow. Testing dierent variations of the
control settings will help you achieve the desired
results. See descriptions and suggested Air 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 nish with thicker
materials.
• Lowering the air
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
Tip: For ne-nish work with thinner materials, you
may want to decrease the air
thinner material at high air
overspray. Overspray is sprayed material that does
not stick to the spray surface and bounces back.
2-Speed Air Power Control
The FLEXiO model 570 is
equipped with a 2-speed air
power control (high / low).
Variable Air Power Control
The FLEXiO model 590 is
equipped with a variable air

Material Flow Control
The material ow 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 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 ow 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
(590 only) or a scrap piece of wood or cardboard.
The spray pattern shape is adjusted by turning
the adjustment ring (iSpray) or air cap ears (Detail
Finish) 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.
Horizontal pattern
Use ‘up and down’

Tips:
1. Start with a fan pattern for painting trim work
(1-5” width) and larger surfaces like doors and
walls (>5” width).
2. Adjust Material & Air Flow settings as shown in
chart based on coating, fan pattern width, and
nozzle.
3. Fine tune the Material and Air Power settings to
achieve the best results for your application.
4. Pull trigger slightly to start the turbine before
pulling all the way to spray material.
5. Use narrow pattern for detailed work, touch up.
6. Recommended settings for Material and Air
Power may change if the coating is thinned.
For coating large surfaces
Use higher air power
Use higher material ow
For coating smaller areas,
corners and edges
Use lower air power
Use lower material ow
*Note: The air cap can be set diagonally on the
Detail Finish nozzle only. To achieve a round
pattern with the iSpray nozzle, see the “Adjust
Spray Width” section.
The room you are spraying must be
properly masked in order to prevent
overspray from covering woodwork,
oors or furnishings. Make sure you
have properly masked the room per the
instructions on the enclosed “Taping
Guide”.
If spraying with an air-assisted spray system is new
or unfamiliar to you, it is advisable to practice on a
piece of scrap wood or cardboard before beginning
on your intended workpiece and/or test with water.
Spray Poster
If you purchased a FLEXiO sprayer model 590, a
spray poster is included with your unit. The spray
poster can be adhered to a spraying surface and can
be used for practice. Follow the guidelines on the
poster.
Surface Preparation
All objects to be sprayed should be thoroughly
cleaned before spraying material on them. Areas
not to be sprayed may, in certain cases, need to be
masked or covered.
Spray Area Preparation
The spray area must be clean and free of dust in
order to avoid blowing dust onto your freshly
sprayed surface.
How to Spray Properly
It is important to keep your arm moving
whenever the gun is being triggered. If
you pause or linger in one spot too long,
too much material will be sprayed to the
surface.
Partially pulling the trigger will start
the turbine, but no material will spray
until the trigger is pulled fully. It is
recommended that the trigger rst be
pulled partially in order to start the
turbine before a spray pass is made.
• Position the spray gun perpendicular to and
six (6) or more inches from the spray surface,
depending upon the spray pattern size desired.
With reduced material ow and air power, you
can get closer to the spraying surface.
• Spray parallel to the surface with smooth passes
at a consistent speed as illustrated below.
Doing this will help avoid irregularities in the
nish (i. e. runs and sags).
• Always apply a thin coat of material on the rst
pass and allow to dry before applying a second,
slightly heavier coat.
• When spraying larger surfaces, overlap each
spray pass by at least 50% This will ensure full
coverage.
• When spraying, always trigger the spray gun
after spray pass has begun and release trigger
before stopping the pass. Always keep the
gun pointed squarely at the spray surface and
overlap passes slightly to obtain the most
consistent and professional nish possible.
Note: When you quit spraying for any length of
time, unplug the sprayer. When you restart, wipe
the nozzle with a damp cloth to remove any dried
paint.
Use the images and guidelines below in order to
assist you in achieving the desired spray pattern for
your project. These are meant to be general starting
points - you may have to slightly modify certain
controls on the system in order to get the exact
performance you need.
Note: It is recommended that the trigger rst be
pulled partially in order to start the turbine before
a spray pass is made.
Large Surface Projects
Generally, high material ow and air power are
needed for spraying large surface areas, such as walls
and decks.
The iSpray nozzle is ideal for these applications and
is designed for broad coverage in either horizontal or
vertical spraying.
• The air cap position will determine the
movement direction of the spray gun.
Small Surface Projects
Generally, low material ow and air power are
needed for spraying smaller surface areas, such as
corners, lattice, or spindles.
For this type of project, reduce power, material ow
and switch to a narrow width when using the iSpray
nozzle.
The Detail Finish Nozzle (standard with model
590, or sold separately) provides an even narrower
pattern for smaller surface projects and ne
nishing. Moving closer to the spray surface
narrows the fan and moving farther away widens it.
OR
• If you feel the material is going on too thin,
increase the material ow.
• If you feel the material is going on too thick,
decrease the material ow even further or move
the spray gun further away from the surface.
Note: If after following the guidelines on
these two pages you are still not getting the
spray performance you need, refer to the
‘Troubleshooting’ section on page 15.
Besides adjusting the controls, other factors that
should be considered when spraying:
• Distance from the spray object - if you are too
far from the spraying surface, the material will
go on too thin, and vice versa.
• Material thickness - if the spray pattern runs
and/or is too splotchy, the material may need to
be thinned.
Note: Only thin the material if absolutely
necessary to improve spray performance. Optimal
spray performance should be acheived simply by
adjusting the various controls on the unit.
If the material needs to be thinned, dilute the
material in steps of 5% - 10% until the desired
spray pattern is acheived.
• Spray gun movement - moving the gun too
quickly will cause the spray pattern to be too
thin and excess overspray. Moving the gun too
slowly will cause the spray pattern to be too
coarse or thick.
It is important that the nozzle seal
inside the nozzle be re-installed
properly. Make sure the cup side of the
seal (the side with the groove) is facing
out towards the front of the nozzle.
