Important User Information
Thank You for Your Purchase!
Before using your sprayer read this Owners Manual for complete instructions on proper use
and safety warnings.
This sprayer is designed to provide superior spray performance with water-based and oil-based
(mineral spirit-type) architectural paints and coatings. This user information is intended to help
you understand the types of materials that can be used with your sprayer.
Please read the information on the material container label to determine if it can be used with
your sprayer. Ask for a Safety Data Sheet (SDS) from your supplier. The container label and
SDS will explain the contents of the material and the specific precautions related to it.
Paints, coatings and clean-up materials generally fit
into one of the following 3 basic categories:
WATER-BASED: The container label should indicate that the material can be
cleaned up with soap and water. Your sprayer is compatible with this type of
material. Your sprayer is NOT compatible with harsh cleaners such as
chlorine bleach.
OIL-BASED: The container label should indicate that the material is
COMBUSTIBILE and can be cleaned up with mineral spirits or paint thinner.
The SDS must indicate that the flash point of the material is above 100° F.
Your sprayer is compatible with this type of material. Use oil-based material
outdoors or in a well-ventilated indoor area with a flow of fresh air. See the
safety warnings in this manual.
FLAMMABLE: This type of material contains flammable solvents such as
xylene, toluene, naphtha, MEK, lacquer thinner, acetone, denatured alcohol,
and turpentine. The container label should indicate that this material is
FLAMMABLE. This type of material is NOT compatible with your sprayer
and CANNOT be used.
FIRE AND EXPLOSION HAZARD
•
Use only non-flammable or water-based
materials, or non-flammable paint thinners.
Do not use materials having flash points
lower than 100° F (38° C). This includes, but
is not limited to, acetone, xylene, toluene, or
naphtha. For more information about your
material, request Safety Data Sheet (SDS)
from the supplier.
• Spraying flammable or combustible
(oil-based) materials in a factory or fixed

Know Your Controls
The ON/OFF power switch controls the main
power to your sprayer.
The Pressure Control knob increases or
decreases the pressure and flow of the paint.
The Prime/Spray Valve directs the fluid to
either the Drain Tube or the hose and gun. It
is used to prime the sprayer, which means to
evacuate the air out of the pump, hose, and
gun.
Your gun will not spray if there is air in the
system. It is necessary to prime the pump,
hose, and gun any time air enters the Suction
Tube.
The Spray Tip is the key to airless spray
technology. High pressure paint pumped
through the very small hole in the Spray Tip
comes out as a spray.
The Spray Tip has the ability to be reversed
and quickly clear clogs.

Strain the Paint
Disposable paint strainer bags are used to
remove coarse particles and debris from
new or previously opened paint or stain, and
are available where paint is sold. To avoid
priming problems and Spray Tip clogs it is
recommended to strain all paints and stains
before spraying. Stretch a disposable paint
strainer bag over a clean pail and pour the
paint through the strainer.
Fill Pump (Prime Pump)
The Prime/Spray Valve directs the fluid to
either the Drain Tube or the hose and gun. It
is used to prime the sprayer, which means to
evacuate the air out of the pump, hose, and
gun.
Your gun will not spray if there is air in the

Refilling Paint Pail
When the paint pail runs low and the gun
stops spraying, refill the paint pail and repeat
the Fill Pump (Prime Pump) procedure,
then the Fill Gun and Hose procedure.
You are now ready to spray!
NOTE: It is normal for the motor to stop once
the sprayer is primed and under pressure. If
the motor continues to run, the sprayer is not
primed. Repeat the Fill Pump (Prime Pump)
and Fill Gun and Hose processes.
Blockages
If paint does not come out of the gun, or if
performing pressure relief procedure and
you suspect pressure has not been fully
relieved:
1. VERY SLOWLY loosen the hose
connection to the gun and disconnect
the airless spray hose from the gun.
2. Lower Prime/Spray Valve to SPRAY
position.
3. While holding hose firmly, point end of
hose into paint pail and turn ON/OFF
switch to ON position.

Spraying
Start
1. Turn pressure control knob to START
position.
2. Disengage trigger lock.
Adjust Pressure Control
To select a setting, align symbol on pressure control knob with setting indicator on sprayer.
1. For best spray results with lowest overspray, adjust pressure control to “START” setting.
2. Test the spray pattern on a test area or piece of cardboard.
3. If needed, increase Pressure Control Knob setting to minimum setting that results in an
acceptable spray pattern.
Spray Pattern Quality
A good spray pattern is evenly distributed as
it hits the surface.
• Spray should be atomized (evenly dis-
tributed, no gaps at edges).
• Increase Pressure Control Knob if
needed until spray is even and without
gaps at edges.
• Spray Tip may be worn or a smaller tip
may be needed. See Spray Tip and
Pressure Selection, page 20.
• Material may need to be thinned. If
material needs to be thinned follow
manufacturer’s recommendations.
Spraying
3A6430C EN 19
Spray Techniques
Use a piece of scrap cardboard to practice
these basic spraying techniques before you
begin spraying the surface.
• Hold gun 12 in. (30 cm) from surface
and aim straight at surface. Tilting gun
to direct spray angle causes an uneven
finish.
• Flex wrist to keep gun pointed straight.
Fanning gun to direct spray at angle
causes uneven finish.
Triggering Gun
Pull trigger after starting stroke. Release
trigger before end of stroke. Gun must be
moving when trigger is pulled and released.
Aiming Gun
Aim center of spray of gun at bottom edge of
previous stroke, overlapping each stroke by
half.
Aligning Spray Pattern
1. Relieve pressure. See Pressure Relief
Procedure, page 14. Engage trigger lock.
2. Align guard horizontally to spray a horizontal
pattern.
3. Align guard vertically to spray a vertical pat-
tern.
High-pressure spray is able to inject toxins
into the body and cause serious bodily
injury. Do not stop leaks with hand or rag.

Spray Tip and Pressure Selection
Spray Tips come in a variety of sizes for spraying a wide range of materials. Your sprayer
includes a 515 Spray Tip for use with most paints on large surfaces such as walls and ceilings.
If you are spraying stain or need a different spray fan width, refer to the Spray Tip chart below
to select the best Spray Tip for your project. Additional Spray Tip sizes are available where paint
sprayers are sold.
1. What material are you spraying?
• The thicker the material, the larger
Spray Tip size you will need.
2. What spray fan width is needed for your
project?
• Narrow spray fan for smaller
projects
• Wider spray fan for larger projects
3. Confirm your sprayer can be used with
your Spray Tip size.
Tip Number Calculation:
• The first digit is half of the fan width
(#5 x 2 = 10 inch fan width).
• The last two digits are the size of the
tip opening in thousandths of an
inch.
• As you spray, the Spray Tip wears and as a result, the hole size gets larger. Starting with
a Spray Tip hole size smaller than the maximum will allow you to spray longer within the
compatibility of the sprayer.
• Spray Tips wear with use and need periodic replacement.

Oil- or Water-Based Materials
•
When spraying water-based materi-
als, flush the system thoroughly with
water.
• When spraying oil-based materials,
flush the system thoroughly with min-
eral spirits or compatible oil-based
flushing fluid.
• To spray water-based materials after
spraying oil-based materials, flush the
system thoroughly with water first. The
water flowing out of Drain Tube should
be clear before you begin spraying the
water-based material.
• To spray oil-based materials after
spraying water-based materials, flush
the system thoroughly with mineral spir-
its or a compatible oil-based flushing
fluid first. The fluid flowing out of the
Drain Tube should not contain any
water. When flushing with oil-based
flushing fluid always follow Static
Grounding Instructions (Oil-Based
Materials), page 29.
• To avoid fluid splashing back on your
skin or into your eyes, always aim gun
at inside wall of pail.
Static Grounding
Instructions (Oil-Based
Materials)
Always use a metal pail for oil-based
materials when sprayer is flushed or pressure
is relieved.
Follow local code. Use only conductive metal
pails, placed on a grounded surface such as
concrete.
Do not place pail on a non-conductive surface
such as paper or cardboard which interrupts
grounding continuity.
Always ground a metal pail: connect a
ground wire to the pail. Clamp one end to the
pail and the other end to a true earth ground
such as a water pipe.
To maintain ground continuity when
sprayer is flushed or pressure is relieved:
hold metal part of gun firmly to the side of a
grounded metal pail, then trigger the gun.
The equipment must be grounded to
reduce the risk of static sparking. Static
sparking can cause fumes to ignite or
explode. Grounding provides an escape
wire for the electric current.
