FIRE AND EXPLOSION HAZARD
844-241-9499
Use only non-flammable or water-based materials, or
non-flammable paint thinners. Do not use materials
having flash points below 100°F (38°C). This includes,
but is not limited to, acetone, xylene, toluene, and
naphtha. For more information about your material,
request Safety Data Sheet (SDS) from the supplier.
Use oil-based materials outdoors or in a well-ventilated
indoor area with a flow of fresh air.
Spraying certain materials may cause static build-up in
the sprayer that can result in static shock to the user. If
this occurs, the material likely contains a flammable
solvent that can build up static and result in a fire or
explosion. Switch to an alternative material.
For portable spray applications of water-based and oil-based
non-flammable architectural paints and coatings only.
Not approved for use in explosive atmospheres or hazardous locations.

Important User Information
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.
Congratulations! You have purchased a high-quality paint sprayer made by Graco Inc.
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 non-flammable
paint thinner. The SDS must indicate that the flash point of the material is above
100°F (38°C). 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.

Warnings
Warnings
The following warnings are for the setup, use, maintenance, and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbols refer to
procedure-specific risks. When these symbols appear in the body of this manual or on warning
labels, refer back to these Warnings. Product-specific hazard symbols and warnings not
covered in this section may appear throughout the body of this manual where applicable.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help
prevent fire and explosion:
• Sprayer generates sparks. Do not spray or flush with flammable materials.
• Do not spray or clean with materials having flash points lower than 100°F (38°C).
• Use only non-flammable or water-based materials, or non-flammable paint thinners. For
complete information about your material, request the Safety Data Sheet (SDS) from the
material distributor or retailer.
• Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.
• When spraying oil-based material, use outdoors or in a well-ventilated indoor area with a
flow of fresh air.
• Do not spray combustible materials near an open flame or sources of ignition such as
cigarettes, motors, and electrical equipment.
• Paint or solvent flowing through the equipment is able to result in static electricity. Static
electricity creates a risk of fire or explosion in the presence of paint or solvent fumes.
• Keep sprayer at least 10 in. (25 cm) away from objects while spraying or flushing.
• Do not use a paint or a solvent containing halogenated hydrocarbons.
• Verify that all containers and collection systems are grounded to prevent static discharge.
• Do not smoke in the spray area or spray where sparks or flame is present.
• Do not operate light switches, engines, or similar spark producing products in the spray
area.
• Keep area clean and free of paint or solvent containers, rags, and other flammable
materials.
• Know the contents of the paints and solvents being sprayed. Read all Safety Data Sheet
(SDS) and container labels provided with the paints and solvents. Follow the paint and
solvents manufacturer’s safety instructions.
• Fire extinguisher equipment shall be present and working.

Warnings
SKIN INJECTION HAZARD
High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the
event that injection occurs, get immediate surgical treatment.
• Do not aim the gun at, or spray any person or animal.
• Keep hands and other body parts away from the discharge. For example, do not try to stop
leaks with any part of the body.
• Always use the spray tip guard. Do not spray without spray tip guard in place.
• Use Graco spray tips.
• Use caution when cleaning and changing spray tips. In the case where the spray tip clogs
while spraying, follow the Pressure Relief Procedure for turning off the unit and relieving
the pressure before removing the spray tip to clean.
• Do not leave the equipment energized or under pressure while unattended. Remove
battery and follow the Pressure Relief Procedure when the equipment is unattended or
not in use, and before servicing, cleaning, or removing parts.
• Check parts for signs of damage. Replace any damaged parts.
• This system is capable of producing 2000 psi (138 bar, 14 MPa). Use Graco replacement
parts or accessories that are rated a minimum of 2000 psi (138 bar, 14 MPa).
• Verify that all connections are secure before operating the unit.
• Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the
controls.

DEWALT batteries and battery chargers.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death,
serious injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents.
• Do not use chlorine bleach.
