WARNING
FLUID UNDER HIGH PRESSURE CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
TERMS
Be sure you red and understand each of these
terms before reading the rest of the manual.
WARNING: Alerts user to avoid or correct
conditions that could cause bodily injury.
CAUTION: Alerts user to avoid or correct
conditions that could cause damage to or
destruction of equipment.
NOTE: Identifies essential procedures or extra
information.
FLEXIBLE EXTENSION: A flexible rubber hose
extending form the dispensing valve, to which a
grease fitting coupler is attached.
RIGID EXTENSION: A rigid tube extending from
the dispensing valve, to which a grease fitting
coupler is attached.
GREASE FITTING COUPLER: The device at the
end of the flexible or rigid extension which
connects to the parts to be lubricated.
FLUID INJECTION HAZARD
Fluid emitted under high pressure from leaks or
ruptured components can penetrate the skin and
cause extremely serious bodily injury, including the
need for amputation. Also, fluid injected or
splashed into the eyes can cause serious damage.
Dispense Valve Safety
Do not modify any part of the dispensing valve.
Only use extensions and grease fitting couplers
which are designed for use with your dispensing
valve. Modifying parts can cause a malfunction
and result in serious bodily injury.
Flexible Extension Safety
Be sure you know the maximum working pressure
of the flexible extension you are using. Never
exceed that pressure, even if your dispensing
valve and/or pump is rated for higher working
pressures.
Never use a low pressure flexible extension,
designed for low pressure dispensing valves or
hand-powered lubricating equipment, on a high
pressure dispensing valve.
Never attempt to force the lubricant into a
fitting!
If the lubricant is not flowing, STOP
DISPENSING IMMEDIATELY! The fitting may be
clogged. Forcing lubricant may cause excessive
back pressure in the flexible extension which could
cause it to rupture and result in serious bodily
injury, including injection and eye injury.
Grease Fitting Coupler Safety
Use extreme caution when cleaning or changing
grease fitting couplers. If the coupler clogs while
dispensing, STOP DISPENSING IMMEDIATELY!
Follow the Pressure Relief Procedure. Then
remove the coupler to clean it. Never wipe off
buildup around the coupler until pressure is fully
relieved.
General Safety
Check the operation of all equipment safety
devices before each use.
NEVER point the dispensing valve at anyone or
any part of the body.
NEVER put hand or fingers over the grease fitting
coupler.
NEVER try to stop or deflect leaks with your hand
or body.

3
Medical Alert - Airless Spray Wounds
If any fluid appears to penetrate your skin, get
EMERGENCY MEDICAL CARE AT ONCE. DO
NOT TREAT AS A SIMPLE CUT. Tell the doctor
exactly what fluid was injected.
Note to Physician: Injection in the skin is a
traumatic injury. It is important to treat the injury
surgically as soon as possible. Do not delay
treatment to research toxicity. Toxicity is a concern
with some exotic coatings injected directly into the
blood stream. Consultation with a plastic surgeon
or reconstructive hand surgeon may be advisable.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
injection, or splashing in the eyes or on the skin;
always follow this procedure whenever you shut off
the pump, and before inspecting, removing,
cleaning or repairing any part of the pump or
system.
1. Close the pump air regulator
2. Close the supply pump’s bleed-type master air
valve (required in the system).
3. Open the dispensing valve until pressure is
fully relieved.
If you suspect that the dispensing valve, extension
or grease fitting coupler is clogged, or that pressure
has not been fully relieved after following the steps
above, VERY SLOWLY loosen the coupler or hose
end coupling and relieve pressure gradually, then
loosen completely. Now clear the clog.
EQUIPMENT MISUSE HAZARD
General Safety
This pump is designed to be used ONLY in
pumping non-corrosive and non-abrasive lubricants
and greases. Any misuse of the spray equipment
or accessories, such as overpressurizing,
modifying parts, using incompatible fluids and
chemicals, or using worn or damaged parts, can
cause them to rupture and result in injection or
other serious bodily injury, fire, explosion or
property damage.
NEVER alter or modify any part of this equipment;
doing so could cause it to malfunction.
CHECK all dispensing equipment regularly and
repair or replace worn or damaged parts
immediately.
System Pressure
DO NOT exceed 3000 PSI (210 bar) MAXIMUM
WORKING PRESSURE to the gun. Be sure all
accessory items and system components are rated
to withstand the pressures developed. NEVER
exceed the pressure rating of nay component in
the system.
Fluid Compatibility
BE SURE that all fluids and solvents used are
chemically compatible with the wetted parts shown
in the Technical Data. Always read the fluid and
solvent manufacturer’s literature before using them
in this sprayer.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the high velocity flow
of fluid through the pump and hose. If every part
of the spray equipment is not properly grounded,
sparking may occur, and the system may become
hazardous. Sparking may also occur when
plugging in or unplugging a power supply cord.
Sparks can ignite fumes from solvents and the
fluid being sprayed, dust particles and other
flammable substances, whether you are spraying
indoors or outdoors, and can cause a fire or
explosion and serious bodily injury and property
damage. Do not plug in or unplug any power
supply cords in the spray area when there is any
chance of igniting fumes still in the air.
If you experience any static sparking or even a
slight shock while using this equipment, STOP
SPRAYING IMMEDIATELY. Check the entire
system proper grounding. Do not use the system
again until the problem has been identified and
corrected.

4
Grounding
To reduce the risk of static sparking, ground the
pump and all the spray equipment used or located
in the spray area. CHECK your local electrical
code for detailed grounding instructions for your
area and type of equipment. BE SURE to ground
all of this spray equipment:
1.
Pump: use a ground wire and clamp as shown
in Figure 1.
2.
Air hoses: use only grounded air hoses.
3.
Fluid hoses: use only grounded fluid hoses.
4. Air compressor: follow manufacturer’s
recommendations.
5.
Spray gun or dispensing valve: grounding is
obtained through connection to a properly
grounded fluid hose and pump.
6.
Object being sprayed: according to your local
code.
7.
All solvent pails used when flushing: according
to local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do
not place the pail on a non-conductive surface,
such as paper or cardboard, which interrupts
the grounding continuity.
8.
To maintain grounding continuity when flushing
or relieving pressure:
always hold a metal part
of the gun/valve firmly to the side of a
grounded metal pail, then trigger the
gun/valve.
Figure 1
To ground the pump, loosen the grounding lug
locknut (A) and washer (B). Insert one end of a 12
ga (1.5mm2) minimum ground wire (D) into the slot
in lug (C) and tighten locknut securely. See Figure
1. Connect the other end of the wire to a true earth
ground. Refer to ground wire and clamp in
ACCESSORIES.
Flushing Safety
To reduce the risk of injection injury, static
sparking, or splashing, follow the Pressure Relief
Procedure.
Remove the spray tip (spray guns or
spray valves only) before flushing.
Hold a metal
part of the gun/valve firmly to the side of a
grounded metal pail and use the lowest possible
fluid pressure during flushing.

5
MOVING PARTS HAZARD
The piston in the air motor, located behind the air
motor plates, moves when air is supplied to the
motor. Moving parts can pinch or amputate your
fingers or other body parts. KEEP CLEAR of
moving parts when starting or operating the
sprayer. Follow the Pressure Relief Procedure
before checking or servicing the sprayer to prevent
it from starting accidentally.
Before clearing an obstruction from the priming
piston or servicing the pump, follow the Pressure
Relief Procedure to prevent the pump from starting
accidentally.
WARNING
Priming Piston Hazard
Moving parts can pinch or amputate your fingers or
other body parts. When the pump is operating, the
priming piston (Q) (located at the pump intake)
moves up and down inside the intake valve.
NEVER put your fingers or tools into the slots of
the intake valve when the pump is operating or the
pressure is not fully relieved. Before attempting to
clear an obstruction from the priming piston (Q) or
service the pump, follow the Pressure Relief
Procedure to prevent the pump from accidentally
starting.

6
HOSE SAFETY
High pressure fluid in the hoses can be very
dangerous. If the hose develops a leak, split or
rupture due to any kind of wear, damage or
misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious bodily
injury or property damage.
ALL FLUID SPRAY HOSES MUST HAVE
SPRING GUARDS! (except certain mastic
applications). The spring guards help protect the
hose from kinks or bends at or close to the
coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before
each use. High pressure fluid can dislodge a loose
coupling or allow high pressure spray to be emitted
from the coupling.
NEVER use a damaged hose. Before each use,
check entire hose for cuts, leaks, abrasion, bulging
cover, or damage or movement of the hose
couplings. If any of these conditions exist, replace
the hose immediately. DO NOT try to recouple
high pressure hose or mend it with tape or any
other device. A repaired hose cannot contain the
high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do
not pull on hoses to move equipment. Do not use
fluids or solvents which are not compatible with the
inner tube and cover of the hose. DO NOT expose
Graco hose to temperatures above 180°F
(82°C) or below -40°F (-40°C).
Hose Grounding Continuity
Proper hose grounding continuity is essential to
maintaining a grounded spray system. Check the
electrical resistance of your air and fluid hoses at
least once a week. If your hose does not have a
tag on it which specifies the maximum electrical
resistance, contact the hose supplier or
manufacturer for the maximum resistance limits.
Use a resistance meter in the appropriate range
for your hose to check the resistance. If the
resistance exceeds the recommended limits,
replace it immediately. An ungrounded or poorly
grounded hose can make your system hazardous.
Also read FIRE OR EXPLOSION HAZARD.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and
Health Act. Theses standards-particularly the General Standards, Part 1910, and the Construction
Standards, Part 1926 - should be consulted.

INSTALLATION
NOTE: Reference numbers and letters in
parentheses in the test refer to the Typical
Installation, Figure 1, 2 and the Parts Drawing.
Mount the pump to suit the type of installation
planned. Very heavy lubricants may require an
inductor plate. See ACCESSORIES for the mount
and DIMENSIONS for the mounting hole layout.
Install the air line accessories in the approximate
order shown in the Typical Installation. Install a
bleed-type master air valve (B) within easy reach
of the pump, upstream from the air regulator.
Install an air filter (C) to remove harmful dirt and
moisture from your compressed air supply.
For automatic air motor lubrication, install an air
line oiler (D) close to the pump air inlet. Install an
air regulator (E) to control pump speed.
WARNING
The bleed-type master air valve (B) is required to
shut off and relieve air pressure that may be
trapped in the air motor. Trapped air could cause
the pump to cycle unexpectedly and cause serious
bodily injury, including amputation.
Be sure the air hose is properly sized to deliver an
adequate supply of air to the motor. Refer to the
Technical Data.
Connect a dispensing hose to the 3/4” npt (f) pump
outlet. Install an appropriate gun or dispensing
valve to the hose.
Grounding
Proper grounding is essential to maintaining a safe
system. Read FIRE OR EXPLOSION HAZARD

OPERATION
WARNING
To reduce the risk of serious bodily injury, including
injection,
always follow the Pressure Relief
Procedure whenever you shut off the pump, and
before inspecting, removing cleaning or repairing
any part of the pump or system.
For your safety in operating and servicing this
pump, thoroughly read and follow all warning and
instruction given in this manual and in any other
manual supplied with this pump or any accessories
you add to the system.
Moving parts can pinch or amputate your fingers or
other body parts.
When the pump is operating, the
priming piston (located at the pump intake) and the
air motor piston (located behind the air motor
plates) move. Therefore, NEVER operate the
pump with the air motor plates removed, and keep
your fingers and hands away form the priming
piston.
Before clearing an obstruction from the priming
piston or servicing the pump
, follow the Pressure
Relief Procedure to prevent the pump from
starting accidentally.
Open the bleed-type master air valve. Open the
dispensing valve and slowly open the air regulator
until the pump is running smoothly. After all the air
is purged, close the dispensing valve - the pump
will start and stop as the valve is opened and
closed.
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed, and may damage itself. If your pump
accelerates quickly, or is running too fast, stop it
immediately and check the fluid supply. If the
supply container is empty and air has been
pumped into the lines, prime the pump and lines
with fluid, or flush the pump and leave it filled with
compatible solvent. Be sure to eliminate all air
from the fluid system.
Use the air regulator (E) to control pump speed
and fluid pressure. See the Typical Installation.
Always use the lowest pressure necessary to obtain
the desired results.
When you are done using the pump for the day,
always follow the Pressure Relief Procedure.
MAINTENANCE
Lubrication
The accessory air line oiler (D) provides automatic air motor lubrication. For daily, manual lubrication,
disconnect the air hose, place about 15 drops of light machine oil in the air inlet, reconnect the hose and
turn on the air supply to blow oil into the motor.

The Graco Warranty and Disclaimers
WARRANTY
Graco warrants all equipment manufactured by it and bearing its name to be free from defects in material and
workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. As
purchaser’s sole remedy for breach of this warranty, Graco will, for a period of twelve months or two thousand
hours of operation from time of sale, repair or replace any part of the equipment proven 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, any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident,
tampering, or substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or
wear caused by the incompatibility with Graco equipment of 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 claim. 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 includes the costs of parts, labor and transportation.
DISCLAIMERS AND LIMITATIONS
The terms of this warranty constitute purchaser’s sole and exclusive remedy and are in lieu of any other warranties
(express or implied), including warranty of merchantability or warranty of fitness for a particular purpose,
and of any non-contractual liabilities, including production liabilities, based on negligence or strict liability. Every
form of liability for direct, special or consequential damages or loss is expressly excluded and denied. In no case
shall Graco’s liability exceed the amount of the purchase price. Any action for breach of warranty must be brought
within two (2) years of the date of sale.
EQUIPMENT NOT COVERED BY GRACO WARRANTY
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular
purpose, with respect to accessories, equipment, materials, or components sold but not manufactured by Graco.
These items sold, but not manufactured by Graco (such as electric motor, switches, hose, etc.) are subject to the
warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any
