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.

Know Your Controls
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.

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.
a. If fluid does not flow out of hose,
replace the hose and continue to
step 4.
b. If fluid flows out of hose, see Clean
the Gun and Gun Filter, page 26.
4. Reassemble the hose and gun, and
repeat Fill Gun and Hose, page 16.
6. Rotate Spray Tip back to SPRAY
position and ensure the Spray Tip Guard
is tight.
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.

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. 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.
18 3A5431B EN
Spraying
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.
3A5431B EN 19
Spraying
Spray Tip and Pressure Selection
Spray Tips come in a variety of sizes for spraying a range of fluids. Your sprayer includes a
Spray Tip for use in most paint spraying applications. See Coatings Chart below to find the
correct Spray Tip size for your coating. Refer to paint (material) can for manufacturer’s
recommendation. Alternate Spray Tip sizes can be purchased where sprayers are sold.
• Spray Tip hole size is calculated by the last two digits of the Spray Tip size, the “15” in
“515” means the Spray Tip hole size is .015 inch.
Do not use a Spray Tip hole size larger than what is supported by your sprayer:
• Project Painter Plus and X5 and LTS15 max Spray Tip size: 0.015 inch.
• X7 and LTS17 max Spray Tip size: 0.017 inch.

• Use a smaller Spray Tip hole size when applying thinner materials and larger sizes for
thicker materials.
• The larger the size of the Spray Tip hole, the faster the material leaves the gun. A 313
Spray Tip sprays faster than a 411 Spray Tip.
• 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
rated flow capacity of the sprayer.
• Spray Tips wear with use and need periodic replacement.
Spray Tip Fan Width
Fan width is the size of the spray pattern, which determines the area covered with each stroke.
• The first digit in the Spray Tip size is doubled to determine the approximate fan width.
The “5” in “515” equals an approximate 10 inch spray fan width (5 x 2 = 10).

Cleaning Fluid Compatibility
Oil- or Water-Based Materials
•
When spraying water-based materials, flush the system thoroughly with
water.
• When spraying oil-based materials,
flush the system thoroughly with mineral 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 spirits 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)
The equipment must be grounded to
reduce the risk of static sparking and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric shock.
A good ground provides an escape wire for
the electric current.
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.

Maintenance
Maintenance
Routine maintenance is important to ensure proper operation of your sprayer.
Maintenance Activity
1. Inspect motor shroud openings for
blockage every time you spray.
2. Clean/inspect inlet screen and gun filter
every time you spray. Replace if the filter
cannot be cleaned or is damaged.
NOTICE
Protect the internal drive parts of this
sprayer from water. Openings in shroud
allow cooling of mechanical parts and
electronics inside. If water gets into these
openings, the sprayer could malfunction or
be permanently damaged.
Airless Hoses
Check hose for damage every time you
spray. Do not attempt to repair hose if hose
jacket or fittings are damaged. Do not use
hoses shorter than 25 ft. (7.6 m). Wrench
tighten, using two wrenches.
Spray Tips
• Always clean Spray Tips with compati-
ble cleaning fluid and brush after spraying.
• Tips may require replacement after 15
gallons (57 liters) or they may last
through 60 gallons (227 liters) depending on abrasiveness of paint. See
Spray Pattern Quality, page 18.

Graco Standard Warranty
Graco Standard Warranty
Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing
its name to be free from defects in material and workmanship on the date of sale to the original purchaser
for use. With the exception of any special, extended, or limited warranty published by Graco, Graco will,
for a period of twelve months from the date of sale, repair or replace any part of the equipment
determined by Graco to be defective. This warranty applies only when the equipment is installed,
operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction,
damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or
improper maintenance, negligence, accident, tampering, or substitution of non-Graco component parts.
Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of equipment
with structures, accessories, equipment or materials not supplied by Graco, or the improper design,
manufacture, installation, operation or maintenance of structures, accessories, equipment or materials
not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an
authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco
will repair or replace free of charge any defective parts. The equipment will be returned to the original
purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material
or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of
parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY
OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above.
The buyer agrees that no other remedy (including, but not limited to, incidental or consequential
damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential
loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.
GRACO MAKES NO WARRANTY, AND DISCLAIMS ALL IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, IN CONNECTION WITH
ACCESSORIES, EQUIPMENT, MATERIALS OR COMPONENTS SOLD BUT NOT MANUFACTURED
BY GRACO. These items sold, but not manufactured by Graco (such as electric motors, switches, hose,
etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with
reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from
Graco supplying equipment hereunder, or the furnishing, performance, or use of any products or other
