Warnings
Warnings
The following warnings are for the setup, use, grounding, maintenance and repair of this equipment. The exclamation
point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risks. Refer back to
these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
WARNING
WARNINGWARNINGWARNING
GROUNDING
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.
• Improper installation of the grounding plug is able to result in a risk of electric shock.
• Check with a qualified electrician or serviceman when the grounding instructions are not completely
understood, or when in doubt as to whether the product is properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.
• This product is for use on a nominal 240V circuit and has a grounding plug similar to the plug illustrated in the figure below.
• Only connect the product to an outlet having the same configuration as the plug.
• Do not use an adapter with this product.
Extension Cords:
• Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that
accepts the plug on the product.
• Make sure your extension cord is not damaged. If an extension cord is necessary, use 15m (49.2 ft)

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:
• Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes,
motors, and electrical equipment.
• Only use water-based or mineral spirit-type materials with a flash point greater than 70° F (21° C).
• 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. All parts of the spray system, including the pump,
hose assembly, spray gun, and objects in and around the spray area shall be properly grounded to protect
against static discharge and sparks. Use Graco conductive or grounded high-pressure airless paint sprayer
hoses.
• Verify that all containers and collection systems are grounded to prevent static discharge.
• Connect to a grounded outlet and use grounded extensions cords. Do not use a 3-to-2 adapter.
• Do not use a paint or a solvent containing halogenated hydrocarbons.
• Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area. Keep pump assembly
in a well ventilated area. Do not spray pump assembly.
• Do not smoke in the spray area.
• 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.
• Fire extinguisher equipment shall be present and working.
• Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for flushing or cleaning, keep
sprayer at least 20 feet (6 m) away from explosive vapors.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Use only grounded electrical outlets.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on power and extension cords.
• Do not expose to rain. Store indoors.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing
equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but
it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing
equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.
• Read MSDSs to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
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.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for
compatibility.
RECOIL HAZARD
Gun may recoil when triggered. If you are not standing securely, you could fall and be seriously injured.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component.
See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment
manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material,
request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment and follow
the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s
replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
STARTUP HAZARD AFTER THERMAL OVERLOAD
Motor has thermal overload switch to shut itself down if overheated. To reduce risk of injury from motor restarting
unexpectedly when it cools, always turn power switch OFF if motor shuts down.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the
equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and
burns. This equipment includes but is not limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.

Grounding Instructions
Grounding Instructions
Sprayer must be grounded. Grounding reduces the
risk of static and electric shock by providing an escape
wire for electrical current due to static build up or in the
event of a short circuit.
3. Do not use an extension cord with damaged ground
plug.
Recommended extension cords:
• 15 m (49.2 ft) 1.0 mm
• 30 m (98.4 ft) 1.5 mm
• 50 m (164.0 ft) 2.5 mm

1. This sprayer requires 220-240 VAC, 50/60 Hz 10A
circuit with a grounding receptacle. Never use an
outlet that is not grounded.
2. Do not use sprayer if electrical cord has damaged
ground prong.
4. Smaller gauge or longer extension cords may
reduce sprayer performance.
Thermal Overload
Motor has a thermal overload switch to shut itself down
if overheated. If unit overheats, allow approximately 45
minutes for unit to cool. Once cool, switch will close and
unit will restart.
To reduce risk of injury from motor starting unexpectedly when it cools, always turn power switch OFF if
motor shuts down.
