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 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.
WARNING
WARNINGWARNINGWARNING
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.
• 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. Do not
use pail liners unless they are are antistatic or conductive.
• 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.
• Know the contents of the paints and solvents being sprayed. Read all Material Safety Data Sheets
(MSDS) 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.
• 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.

Warnings
WARNING
WARNINGWARNINGWARNING
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 nozzle tip guard. Do not spray without nozzle tip guard in place.
• Use Graco nozzle tips.
• Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while
spraying, follow the Pressure Relief Procedure for turning off the unit and relieving the pressure
before removing the nozzle tip to clean.
• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn
off the unit and follow the Pressure Relief Procedure for turning off the unit.
• Check hoses and parts for signs of damage. Replace any damaged hoses or parts.
• This system is capable of producing 3300 psi (22.7 MPa, 227 bar). Use Graco replacement parts or
accessories that are rated a minimum of 3300 psi (22.7 MPa, 227 bar).
• Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.
• 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.
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.
• Connect only to 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
• Wait five minutes after disconnecting power cord before servicing large capacitor units.
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.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure and disconnect all power sources.

WARNING
WARNINGWARNINGWARNING
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective 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.

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.
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. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• 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.

Grounding
Grounding
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.
Sprayer Cord: The sprayer cord includes a grounding
wire with an appropriate grounding contact.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
ti11730a
Do not modify plug! If it will not fit in outlet, have
grounded outlet installed by a qualified electrician.
Do not use an adapter.
Power Requirements
230V units require 220-240 VAC, 50/60 Hz, 8A
332250A 7
Extension Cords
• Smaller gauge or larger extension cords may
reduce sprayer performance.
• Use an extension cord with an undamaged ground
contact.
Page 8
Grounding
Pails
Solvent and oil/based fluids: follow local code. Use
only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface,
such as paper or cardboard, which interrupts grounding
continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of spray gun firmly
to side of a grounded metal pail. Then trigger gun.
ti21126a
ti5850b
Grounding a metal pail: connect a ground wire to the
pail by clamping one end to pail and other end to a true
earth ground such as a water pipe.
