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.

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:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• 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.

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground equipment and conductive objects in work area. Read Grounding instructions.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

• Keep a fire extinguisher in the work area.

ELECTRIC SHOCK HAZARD

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 sprayer and extension cords.

• Do not expose to rain. Store indoors.

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 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.

• Engage trigger lock when not spraying.

•Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

Warnings

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed the maximum working pressure or temperature rating of the lowest

rated system component. Read Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. Read

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.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine Graco replacement parts only.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your Graco distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or overbend hoses or use hoses to pull equipment.

• Comply with all applicable safety regulations.

• Keep children and animals away from work area.

• Do not operate the unity when fatigued or under the influence of drugs or alcohol.

PRESSURIZED ALUMINUM PARTS HAZARD

Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.

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 MSDS’s 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.

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, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eye wear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

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.

• The 120 Vac sprayers require 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:

WLD

WLD

• 50 ft (15.0 m) 16 AWG (1.0 mm

• 100 ft (30.0 m) 14 AWG (1.5 mm

)

Smaller gauge or longer extension cords may reduce sprayer performance.

Spray gun

: ground through connection to a prop-

erly grounded fluid hose and pump.

Fluid supply container

Solvent pails used when flushing

: follow local code.

: follow local

code. Use only conductive metal pails, placed on a grounded surface such as concrete. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

Grounding the metal pail

: connect a ground wire

to the pail by clamping one end to pail and other end to ground such as a water pipe.

Maintaining grounding continuity when flushing or relieving pressure: hold metal part of

the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

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 the risk of injury from motor starting unexpectedly when it cools, always turn power switch OFF if motor shuts down.

Getting Started

Pressure Relief Procedure

Follow this Pressure Relief Procedure when you stop spraying and before cleaning, checking, servicing, or transporting equipment.

1. Set AllControl to OFF. Unplug sprayer.

ti9168a

2. Hold gun firmly to the side of a pail. Trigger the gun to relieve pressure.

3. Engage trigger lock. See Trigger Lock, page 7.

If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the previous steps, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction. Read Unclogging Spray Tip, page 14.

Trigger Lock

Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.

Oil- or Water-based Materials

• When spraying water-based materials,

flush the system thoroughly with water.

• When spraying oil-based materials, flush

the system thoroughly with mineral spirits or compatible, oil-based flushing solvent.

•To spray water-based materials after spraying oil-based materials, flush the system thoroughly with water first. The water flowing out of prime tube should be clear and solvent-free before you begin spraying the water-based material.

•To spray oil-based materials after spraying water-based materials, flush the system thoroughly with mineral spirits or a compatible oil-based flushing solvent first. The solvent flowing out of the prime tube should not contain any water.

• When flushing with solvents, ground gun. Read Grounding and Electric Requirements, page 4.

• To avoid fluid splashing back on your skin or into your eyes, always aim gun at inside wall of pail.
