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.
INSTRUCTIONS
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.

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.
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:
D

D
25 ft (7.6 m) 18 AWG
50 ft (15.2 m) 16 AWG
100 ft (30.5 m) 14 AWG

Smaller gauge or longer extension cords may reduce sprayer
performance.

properly grounded fluid hose and pump.

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.
ti5850a
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.
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
D Motor has a thermal overload switch
to shut itself down if overheated.
To reduce risk of injury from motor staring
unexpectedly when it cools, always turn power
switch OFF if motor shuts down.

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

NOTE: The Contractort In–line Valve
can be used as an airless spray gun
for small jobs by attaching a Handtite-
t 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

Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco,
Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide
purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
