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. 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

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.

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.

Pressure Relief Procedure

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

If you suspect the spray tip or hose is clogged or that
pressure has not been fully relieved after following the
steps above, 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 instructions in the Sprayer
or Gun Operation manual.

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 17 and Advanced Trouble-
shooting, page 21.

• 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.

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.

• 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.
