Important Safety Instructions
Read all warnings and instructions in this
manual. Save these instructions.
This equipment is not intended for use with flammable or combustible materials used in places such as
cabinet shops or other “factory” or fixed locations. If you intend to use this equipment in this type of
application, you must comply with NFPA 33 and OSHA requirements for the use of flammable and
combustible materials.
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:
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.

INSTRUCTIONS
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 attention.
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.
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.
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

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.

Grounding and Electric Requirements
The sprayer must be grounded. Grounding reduces the risk of static
and electric shock by providing and escape wire for the electrical
current due to static build up or in the event of a short circuit.
ti5572a
ti3001b
D The sprayer requires a 120V AC, 60 Hz, 15A circuit
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:
D25 ft (7.6 m) 18 AWG
D50 ft (15.2 m) 16 AWG
D100 ft (30.5 m) 14 AWG
D150 ft. (45.7 m) 12 AWG
Smaller gauge or longer extension cords may reduce sprayer
performance.
4309388
D Ground sprayer gun through connection to a
properly grounded fluid hose and pump.
D Ground fluid supply container. Follow local code.
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
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.
ti5851a
D Motor has a thermal overload switch
to shut itself down if overheated.

Pressure Relief Procedure
1. Turn power switch OFF and unplug power
cord.
2. Turn Spray–Prime/Drain valve to
PRIME/DRAIN to relieve pressure.

3. Turn pressure to lowest setting. Hold metal
part of gun firmly to a grounded metal pail.
Trigger gun to relieve pressure.
4. Engage trigger lock.
D Leave Spray–Prime/Drain valve in PRIME/
DRAIN position until you are ready to spray
again.

D If you suspect the spray tip is clogged or
that pressure has not been fully relieved
after following the above steps, VERY
SLOWLY loosen tip guard retaining nut or
hose end coupling to relieve pressure
gradually. Then loosen completely. Clear
hose or tip obstruction.

Setup
1. Turn power switch OFF.
2. Connect one end of grounded fluid hose
to the In–line Valve. Use a wrench to
tighten.
NOTE: The Contractort In–line Valve
can be used as an airless spray gun
for small jobs by attaching a Handtitet Guard and RAC5 Switchtip.
For larger jobs the sprayer can be
used for airless spraying by attaching
an airless spray gun rated at 2800 psi
(193 bar, 19 MPa) Maximum Working
Pressure or higher.
3. Connect other end of hose to sprayer
fluid outlet fitting. Use a wrench to
tighten.
4. Turn pressure control knob all the way left
(counterclockwise) to minimum pressure.
