Warnings
The following are general warnings related to the setup, use, grounding, maintenance and repair
of this equipment. Additional, more specific warnings may be found throughout the body of this
manual where applicable. Symbols appearing in the body of the manual refer to these general
warnings. When these symbols appear throughout the manual, refer back to these pages for a
description of the specific hazard.
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 instruc-
tions.
• 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.
•FollowPressure Relief Procedure in this manual, when you stop spraying and
before cleaning, checking, or servicing equipment.

Warnings
4309225W
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 dis-
tributor 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 informa-
tion.
• 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 appli-
cable 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 spray-
ers require a 120
Vac, 60 Hz, 15A cir-
cuit with a ground-
ing receptacle. The
230 Vac Model
247328 requires
230 Vac, 50 Hz, 10A with a grounding recepta-
cle, 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 exten-
sion cords for use with this
sprayer:
• 25 ft (7.6 m) 18 AWG (1.0 mm2)
• 50 ft (15.2 m) 16 AWG (1.0 mm2)
• 100 ft (30.5 m) 14 AWG (1.5 mm2)
• 150 ft (45.7 m) 12 AWG (2.5 mm2)
Spray gun:ground through connection to a
properly grounded fluid hose and pump.
Fluid supply container:follow local code.
Solvent pails used when flushing: follow
local code. Use only conductive metal pails,
placed on a grounded surface such as con-
crete. 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 ground-
ing 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.
Smaller gauge or longer extension cords
may reduce sprayer performance.

To reduce risk of injury from motor starting unex-
pectedly when it cools, always turn power switch
OFF if motor shuts down.

Operation
Pressure Relief Procedure
Follow Pressure Relief Procedure when you
stop spraying and before cleaning, checking,
servicing, or transporting equipment. Read
Injection Warning, page 3.
1. Turn power switch (B) OFF
and unplug power cord.
2. Turn Spray-Prime/Drain
valve (J) to PRIME to
relieve pressure.
3. Hold a metal part of the
gun firmly to a grounded metal pail. Trigger
the gun to relieve pressure.
4. Engage trigger lock.
See Trigger Lock,
page 8.
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, page
12.
Trigger Lock
Always engage the trigger lock when you stop
spraying to prevent the gun from being trig-
gered accidentally by hand or if dropped or
bumped.

Priming
Oil- or Water-based Materials
• When spraying with solvents, ground gun.
Read Grounding and Electric Require-
ments, Maintaining grounding continuity,
page 5.
• To avoid fluid splashing back on your skin
or into your eyes, always aim gun at inside
wall of pail.
1. Turn Spray-Prime/Drain
valve to PRIME.
2. Separate prime tube
(smaller) from suction
tube (larger).
3. Place prime tube in waste pail.
4. If spraying oil-based materials, submerge
suction tube in mineral spirits or compatible
oil-based cleaning solvent.
If spraying water-based materials, sub-
merge suction tube in water.
5. Plug sprayer in to grounded outlet.
6. Point gun into waste pail.
7. Turn power switch ON.
8. Increase pressure, by turn-
ing Pressure Control knob
clockwise, until pump starts.
9. Allow fluid to flow out of
prime tube, into waste pail for 30 to 60 sec-
onds.
10.Turn power switch OFF.
To spray lacquers, purchase Lacquer
Conversion Kit 248202, and follow Prim-
ing procedure for oil-based materials.
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 spray-
ing water-based materials, flush the sys-
tem 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.
