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

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.

•

When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade
terminal.

•

The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding
wire.

•

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 120V or 230V circuit and has a grounding plug similar to the plugs illus­trated in the figure below.

110V

120V US 230V

•

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 grounding plug and a grounding receptacle that accepts the plug on
the product.

•

Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG

(2.5 mm

•

An undersized cord results in a drop in line voltage and loss of power and overheating.

Warnings

WARNING

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 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.

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 (227 bar, 22.7 MPa). Use Graco replacement parts or

accessories that are rated a minimum of 3300 psi (227 bar, 22.7 MPa).

• 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.
