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:

D Use equipment only in well ventilated area.

D Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic

drop clothes (potential static arc).

D Sprayer generates sparks. When flammable liquid is used in or near sprayer or for flushing or

cleaning, keep sprayer at least 20 ft (6 m) away from explosive vapors.

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

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

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

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

until you identify and correct the problem.

D Keep a fire extinguisher in the work area.

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

D Turn off and disconnect power cord before servicing equipment.

D Use only grounded electrical outlets

D Use only 3–wire extension cords.

D Ensure ground prongs are intact on sprayer and extension cords.

D Do not expose to rain. Store indoors.

PRESSURIZED ALUMINUM PARTS HAZARD

Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents in this equipment. Such use could result in a serious chemical reaction,
with the possibility of explosion, which could cause death, serious injury and/or substantial property
damage.

INSTRUCTIONS

WARNING

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.

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

D Do not put your hand over the spray tip.

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

D Engage trigger lock when not spraying.

D Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,

checking or servicing equipment.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

D Do not exceed the maximum working pressure or temperature rating of the lowest rated system

component. Read Technical Data in all equipment manuals.

D 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.

D Check equipment daily. Repair or replace worn or damaged parts immediately with genuine Graco

replacement parts only.

D Do not alter or modify equipment.

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

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

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

D Keep children and animals away from work area.

D Do not operate the unit when fatigured or under the influence of drugs or alcohol.

D Comply with all applicable safety regulations.

TOXIC FLUID HAZARD

Toxic fluid or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.

D Read MSDS’s to know the specific hazards of the fluids you are using.

D Store hazardous fluid in approved containers and dispose of it according to all applicable guide-

lines.

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:

D Protective eye wear.

D Clothing and respirator as recommended by the fluid and solvent manufacturer.

D Gloves.

D Hearing protection.

3309859

Grounding and Electric Requirements

The sprayer must be grounded. Grounding reduces the risk of static and
electric shock by providing an escape wire for the electrical current due to
static build up or in the event of a short circuit.

D The sprayer requires a 120V AC, 60 Hz, 15A circuit

ti3001b

with grounding receptacle. Never use an outlet that is
not grounded or an adapter.

D 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.

D Recommended extension cords for use with this sprayer:

D 25 ft (7.6 m) 18 AWG
D 50 ft (15.2 m) 16 AWG
D 100 ft (30.5 m) 14 AWG
D 150 ft. (45.7 m) 12 AWG

ti5572a

Smaller gauge or longer extension cords may reduce sprayer
performance.

D Ground sprayer gun through connection to a

properly grounded fluid hose and pump.

D Ground fluid supply container. Follow local code.

4 309859

Grounding and Electric Requirements

D Ground solvent pails used when flushing. Follow local code. Use

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

D Ground the metal pail by connecting a ground wire to the

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

ti5850a

ti5851a

D Maintain grounding continuity when flushing or

relieving pressure by holding metal part of spray gun
firmly to side of a grounded metal pail, then trigger gun.

Thermal Overload

To reduce risk of injury from motor staring

unexpectedly when it cools, always turn power
switch OFF if motor shuts down.

D Motor has a thermal overload switch

to shut itself down if overheated.
