death if you do not follow instructions.

Symbols, such as fire and explosion (shown), alert you

to a specific hazard and direct you to read the indi-

cated hazard warnings on pages 4-5.

A caution alerts you to possible equipment damage or

destruction if you do not follow instructions.

A note indicates additional helpful information.

Manual Conventions

Warning

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 medical attention.

• Do not point the gun at anyone or at any part of the body.

• Do not put your hand or fingers over the gun fluid nozzle.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Do not “blow back” fluid; this is not an air spray system.

• Follow Pressure Relief Procedure, page 10, when you stop spraying and before cleaning, checking,

or servicing equipment.

• Use lowest possible pressure when flushing, priming, or troubleshooting.

• Never spray without tip guard and trigger guard installed.

• Engage trigger lock when not spraying.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. High pres-

sure hose cannot be recoupled; replace the entire hose.

Fire and Explosion Hazard

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 and plastic drop cloths (potential static

arc).

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

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

• Ground equipment and conductive objects. See Grounding, page 7.

• Hold gun firmly to side of grounded pail when triggering into pail.

• Use only grounded hoses.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment

until you identify and correct the problem.

Burn Hazard

This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To

avoid severe burns:

• Do not touch hot fluid or equipment.

• Allow equipment to cool completely before touching it.

• Wear gloves if fluid temperature exceeds 110° F (43° C).

Manual Conventions

310743A 5

Equipment Misuse Hazard

Misuse can cause serious injury or death.

• For professional use only.

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

• Read manuals, warnings, tags, and labels before operating equipment. Follow instructions.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment. Use only Graco parts and accessories.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-

ponent. See Repair in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Repair in all equip-

ment manuals. Read fluid and solvent manufacturer’s warnings.

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

• Do not use hoses to pull equipment.

• Comply with all applicable safety regulations.

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 swal-

lowed.

• Read Material Safety Data Sheet (MSDS) 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 proper 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, and

hearing loss. This equipment includes but is not limited to:

• Protective eye wear

• Gloves, clothing, and respirator as recommended by the fluid and solvent manufacturer

• Hearing protection

Recoil Hazard

The gun can recoil when triggered at very high pressure. If unprepared, this could force your hand back

or cause you to fall and injure yourself. Be sure you have firm footing and hold the gun securely.

Warning

System Requirements

6310743A

System Requirements

• Install a bleed-type master air valve on a pneumatic pump air supply line to relieve air trapped between this valve and

the pump after air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly.

• Install a fluid drain valve between the pump and gun to relieve pressure in displacement pump, hose, and gun. Trig-

gering gun to relieve pressure may not be sufficient. See Pressure Relief Procedure, page 10.

Grounding

310743A 7

Grounding

Check your local electrical code and pump/sprayer manual for detailed grounding instructions.

•Spray gun: ground through connection to a grounded fluid hose and pump/sprayer.

•Fluid hose: use only grounded hoses.

•Fluid supply container: follow local code.

•Object being sprayed: follow local code.

WARNING

Read warnings, page 3.

•Solvent flushing pails: follow local code. Use only con-

ductive metal pails placed on a grounded surface. Do

not place pail on a non conductive surface, such as

paper or cardboard, which interrupts grounding continu-

ity. TI11021 TI11022

•To maintain grounding continuity when flushing or

relieving pressure: hold metal part of gun firmly to side

of grounded metal pail, then trigger gun.
