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. Refer back to these warnings. Additional, product specific warnings may be found throughout the body of this manual where applicable.

Grounding Instructions

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.

WARNING

GROUNDING

• 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 circuit and has a grounding plug similar to the plug illustrated in the figure below.

ti9164a

• 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 12 AWG (2.5 mm

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

) minimum to carry the current that the product draws.

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. For X5 and X7 models: only use water-based or mineral spirit-type materials with a flash point greater than 70

• 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.

• 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.

° F (21° C).

SKIN INJECTION HAZARD

• 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.

• 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.

• Check hoses and parts for signs of damage. Replace any damaged hoses or parts.

• This system is capable of producing 3000 psi. Use Graco replacement parts or accessories that are rated a minimum of 3000 psi.

• 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.

Installation

Grounding and Electric Requirements

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.

• This sprayer requires a 120 Vac, 60 Hz, 15A circuit with a grounding receptacle.

• Never use an outlet that is not grounded or an adapter.

• Do not use the sprayer if the electrical cord has a damaged ground prong.

• Only use an extension cord with an undamaged 3-prong plug.

Recommended extension cords for use with this sprayer:

• 50 ft (15.0 m) 14 AWG (2.1 mm

• 100 ft (30.0 m) 12 AWG (3.3 mm

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.

Smaller gauge or longer extension cords may reduce sprayer performance.

General Repair Information

To reduce risk of serious injury, including electric shock:

• Do not touch moving or electric pars with fingers or tools while testing repair.

Flammable materials spilled on hot, bare, motor could cause fire or explosion. To reduce risk of burns, fire or explosion, do not operate sprayer with cover removed.

• Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts usually are not provided with replacement kits.

• Test repairs after problems are corrected.

• If sprayer does not operate properly, review repair procedure to verify you did it correctly. See Basic

Troubleshooting, page 11 and Advanced Trouble- shooting, page 16.

• Overspray may build up in the air passages. Remove any overspray and residue from air passages and openings in the enclosures whenever you service sprayer.

• Do not operate the sprayer without the cover in place. Replace if damaged. Covers direct cooling air around motor to prevent overheating.

• Unplug sprayer when power is not required for testing.

• Install all covers, gaskets, screws and washers before you operate sprayer.

CAUTION

• Do not run sprayer dry for more than 30 seconds. Doing so could damage pump packings.

• Protect the internal drive parts of this sprayer from water. Openings in the cover allow for air cooling of the mechanical parts and electronics inside. If water gets in these openings, the sprayer could malfunction or be permanently damaged.

• Prevent pump corrosion and damage from freezing. Never leave water or water-base paint in sprayer when its not in use in cold weather. Freezing fluids can seriously damage sprayer. Store sprayer with Pump Armor to protect sprayer during storage.
