WARNING
HIGH PRESSURE SPRAY CAN
CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD:
General Safety
This equipment generates very high fluid pressure. Spray from
the gun/valve, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes or onto the skin can
cause serious damage.
NEVER point the spray gun or dispensing valve at anyone or at
any part of the body. NEVER put hand or fingers over the
spray tip.
ALWAYS have the tip guard in place on the gun/valve when
spraying.
ALWAYS follow the Pressure Relief Procedure, at right,
before cleaning or removing the spray tip or nozzle or servicing
any system equipment.
NEVER try to “blow back” paint; this is not an air spray pump.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment safety devices are operating properly
before each use.
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 in-
jury. 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.
Spray Gun and Dispensing Valve Safety Devices
Be sure all gun/valve safety devices are operating properly
before each use. Do not remove or modify any part of the
gun /valve; this can cause а malfunction and result in serious
bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set
the gun/valve safety latch in the closed or “safe” position,
making the gun/valve inoperative. Failure to set the safety
latch can result in accidental triggering of the gun/valve.
Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid
injection when the tip is not installed. Check diffuser operation
regularly. Follow the Pressure Relief Procedure, at right,
then remove the spray tip. Aim the gun into a metal pail,
holding the gun firmly to the pail. Using the lowest possible
pressure, trigger the gun. If the fluid emitted /s not diffused in-
to an irregular stream, replace the diffuser immediately.
EQUIPMENT MISUSE HAZARD '
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in fluid 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 spray equipment regularly and repair or replace
worn or damaged parts immediately.
ALWAYS read and follow the fluid and solvent manufacturer's
recommendations regarding the use of protective clothing and
equipment.
7 206-821
Tip Guard
ALWAYS have the tip guard in place on the gun/valve while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce, but does not prevent, the risk of accidental-
ly placing your fingers or any part of your body close to the
spray tip.
Trigger Guard
Never operate the gun with the trigger guard removed. This
guard helps prevent the gun from triggering accidentally if it is
dropped or bumped.
Spray Tip and Nozzle Safety
Use extreme caution when cleaning or changing spray tips or
nozzies. If the spray tip or nozzle clogs while spraying, engage
the gun/valve safety latch immediately. ALWAYS follow the
Pressure Relief Procedure and then remove the spray tip or
nozzle to clean it.
NEVER wipe off build-up around the spray tip or nozzle until
pressure is fully relieved and the gun/vaive safety latch is
engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injec-
tion, splashing in the eyes or on the skin, or injury from mov-
ing parts, always follow this procedure whenever you shut off
the pump, when checking or servicing any part of the system,
when installing or changing spray tips, and whenever you stop
spraying.
1. Engage the spray gun or dispensing valve safety latch.
2 Close the pump air regulator.
3. Close the bleed-type master air valve (required in your
system).
4. Disengage the gun or dispensing valve safety latch.
5. Hold a metal part of the gun or valve firmly to a grounded
metal waste container and trigger to relieve the fluid
pressure.
6. Engage the safety latch again.
7. Open the pump drain valve (required in your system), hav-
ing a container ready to catch the drainage.
8. Leave the drain valve open until you are ready to spray
again.
If you suspect that the spray tip or hose is clogged or that fluid
pressure is not fully relieved after following the steps above,
VERY SLOWLY loosen the tip guard or hose end coupling and
allow pressure to be relieved gradually, then remove complete-
ly. Now clear the tip or hose obstruction.
System Pressure
This pump develops 1000 psi (70 bar) MAXIMUM WORKING
PRESSURE at 100 psi (7 bar) air pressure. Never exceed 100
psi (7 bar) air supply to the motor. NEVER exceed the stated
maximum working pressure of the pump or of the lowest rated
component in your system.
Be sure that all accessories you add to the spray system are
properly rated to withstand the maximum air and fluid working
pressures of this system.
Fluid Compatibility
BE SURE that all fluids and solvents used are chemically com-
patible with the wetted parts shown in the Technical Data on
the back cover. Always read the fluid and solvent manufac-
turer’s literature before using them in this pump.
FIRE OR EXPLOSION HAZARD:
Static electricity is created by the flow of fluid through the
pump and hose. К 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 in-
doors 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 IM-
MEDIATELY. Check the entire system for proper grounding.
Do not use the system again until the problem has been iden-
tified and corrected.
Grounding
To reduce the risk of static sparking, ground the pump and all
other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding in-
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
‚ Pump: use a ground wire and clamp as shown in Fig 1.
‚ Air hoses: use only grounded air hoses.
‚ Fluid hoses: use only grounded fluid hoses.
_ Air compressor: follow manufacturer's recommendations.
n ». WN =
. Spray gun or dispensing valve: grounding is obtained
through connection to a properly grounded fluid hose and
pump.
6. Fluid supply container: according to local code.
7. Object being sprayed: according to your local code.
8. 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 in-
terrupts the grounding continuity.
9. To maintain grounding continuity when flushing or reliev-
ing pressure, always hold a metal part of the gun/valve
firmly to the side of a grounded metal pail, then trigger the
gun/valve.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. № 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 ON BOTH ENDS! (except certain mastic applica-
tions) The spring guards help protect the hose from kinks or
bends at or close to the coupling which can result in hose rup-
ture.
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. Á
repaired hose cannot contain the high pressure fluid.
Fig 1 = rs
To ground the pump, loosen the grounding lug locknut (W)
and washer (X). Insert one end of a 12 ga (1.5 mm2) minimum
ground wire (Y) into the slot in lug (Z) and tighten locknut
securely. See Fig 1. Connect the other end of the wire to a
true earth ground. Refer to page 14 to order a ground wire and
clamp.
Flushing Safety
To reduce the risk of fluid injection injury, static sparking, ог
splashing, follow the Pressure Relief Procedure on page 2,
and 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.
MOVING PARTS HAZARD
The piston in the air motor, located behind the air motor
shield, moves when air is supplied to the motor. Moving parts
can pinch or amputate your fingers or other body parts.
Therefore, NEVER operate the pump with the air motor shield
removed. KEEP CLEAR of moving parts when starting or
operating the pump. Before checking or servicing the pump,
follow the Pressure Relief Procedure on page 2 to prevent
the pump from starting accidentally.
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 ap-
propriate range for your hose to check the resistance. if the
resistance exceeds the recommended limits, replace it im-
mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also, read FIRE OR EXPLOSION
HAZARD, above.
IMPORTANT
United States Government safety standards have been adopted unde
r the Occupational Safety and Health Act. These standards — par-
ticularly the General Standards, Part 1910, and the Construction Standards, Part 1926—should be consulted.

INSTALLATION: 2.
NOTE: Reference numbers and letters in paren-
theses in the text refer to the callouts in the
illustrations and the parts drawings on pages
9-13.
See pages 14 and 15 for accessories that are
available from Graco. Be sure all accessories
are properly sized to withstand the pressures
in the system.
The Typical Installation shown above is only a guide to
selecting and installing required and optional ac-
cessories. For assistance in designing a system to suit
your needs, contact your Graco representative.
Mount the pump to suit the type of installation planned.
The dimensional drawings on page 15 give the measure-
ments needed for installing the pump on a custom
designed mounting. Use 3/8 in. bolts, lockwashers and
nuts to attach the pump firmly to the mounting. If the
pump is wall-mounted, be sure that the mounting is
secure enough to support the weight of the pump and
accessories, and the stress caused by operation.
System Accessories
WARNING
Two accessories are required in your system: a
bleed-type master air valve (A) and a fluid drain
valve (G). These accessories help reduce the risk
of serious bodily injury including fluid injection,
splashing in the eyes or on the skin, and injury
from moving parts if you are adjusting or repairing
the pump.
The bleed-type master air valve relieves air trap-
ped between this valve and the pump after the air
regulator is shut off. Trapped air can cause the
pump to cycle unexpectedly. Locate the valve
close to the pump.
The fluid drain valve assists in relieving fluid
pressure in the displacement pump, hose and
gun; triggering the gun to relieve pressure may
not be sufficient.
4 306-821
(13 mm)
Install the air line accessories in the order shown in the
Typical Installation above. Closest to the pump air inlet,
install a pump runaway valve (B), which senses when
the pump is running too fast and shuts off the air supply
to the motor. For automatic air motor lubrication, install
an air line lubricator (D). Install a bleed-type master air
valve (A) within easy reach of the pump. Next, install an
air regulator (E) to control air to the motor and pump
speed. Furthest from the pump inlet, install an air line
filter (C) to remove harmful dirt and moisture from the
compressed air supply.
Be sure the air supply hose (J) is properly grounded,
and is large enough to supply an adequate volume of air
to the motor.
On the fluid line (H), install a fluid filter (F) and a fluid
drain valve (G) close to the pump's fluid outlet. Connect
a suitable grounded fluid hose from the filter’s outlet to
the gun or dispensing valve.
NOTE: Model 215-876 includes a riser tube which
connects the displacement pump outlet to a
pump outlet at the air motor base. All of the
stubby pump models use the displacement
pump outlet as standard, but have the op-
tional outlet at the air motor base for use if
desired.
If the pump is not immersed, connect a suction tube (K)
to the pump’s intake.
Grounding
Proper grounding is essential to maintaining a safe
system. Read FIRE OR EXPLOSION HAZARD on
page 3, then ground the pump and system as explained
in that section.
WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, in-
cluding fluid injection, splashing in the eyes or on
the skin, or injury from moving parts, always
follow this procedure whenever you shut off the
pump, when checking or servicing any part of the
system, when installing or changing spray tips,
and whenever you stop spraying.
1. Engage the spray gun or dispensing valve safe-
ty latch.
2, Close the pump air regulator.
3. Close the bleed-type master air valve (required
in your system).
4. Disengage the gun or dispensing valve safety
latch.
5. Hold a metal part of the gun or valve firmly to a
grounded metal waste container and trigger to
relieve the fluid pressure.
6. Engage the safety latch again.
7. Open the pump drain valve (required in your
system), having a container ready to catch the
drainage.
8. Leave the drain valve open until you are ready
to spray again.
If you suspect that the spray tip or hose is clogged
or that fluid pressure is not fully relieved after
following the steps above, VERY SLOWLY loosen
the tip guard or hose end coupling and allow
pressure to be relieved gradually, then remove
completely. Now clear the tip or hose obstruction.
WARNING
To reduce the risk of serious bodily injury, in-
cluding fluid injection and splashing in the eyes or
on the skin, and property damage, never exceed
the maximum air and fluid working pressure of the
lowest rated component in your system. See
EQUIPMENT MISUSE HAZARD, System
Pressure, on page 2.
Flush the Pump Before Using
Pumps are tested with lightweight oil which is left in to
protect pump parts. To prevent contamination of fluid,
flush the pump with a compatible solvent before using
it.
in non-immersion applications, fill the wet-cup (118) 1/2
full with Graco Throat Seal Liquid or a compatible sol-
vent, to help prevent the fluid you are pumping from
drying on the displacement rod and damaging the
throat packings.
Starting and Adjusting the Pump
Open the bleed-type master air valve (A). Trigger the
gun into a grounded metal pail, holding a metal part of
the gun firmly to the pail. Slowly open the air regulator
(E) until the pump starts running. Run the pump slowly
until all the air is purged, release the gun trigger, and
engage the safety latch —the pump will start and stop as
the gun is opened and closed. in a circulating system
the pump runs continuously and speeds up or slows
down as the system demands. Always use the lowest
pressure necessary to get the desired results.
Never allow the pump to run dry of fluid being pumped.
A dry pump will quickly accelerate to a high speed,
possibly damaging 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 lines, prime pump and
lines with fluid, or flush and leave filled with compatible
solvent. Be sure to eliminate all air from fluid system.
NOTE: A pump runaway valve (B) can be installed
on the air line to automatically shut off the
pump if it starts to run too fast.
CAUTION
The maximum operating temperature for an im-
mersed pump is 480°F (248°C). Graco will not be
responsible for excessive wear due to pumping
abrasive or corrosive fluids unless it has specifical-
ly recommended such fluids for use in this pump.
Check Valve Adjustment
The piston and intake check valves are factory-set for
light viscosity fluids. This setting minimizes surging at
pump stroke changeover. To adjust the valves for
heavier viscosity fluids, unscrew the four tie boits (106)
and remove the intake valve (103) and cylinder (110).
Remove the ball stop pins (111 and 113) and move them
to a higher set of holes to increase the ball travel. See
Fig 2.

Shutdown and Care of the Pump
Always stop the pump at the bottom of its stroke to pre-
vent fluid from drying on the rod and damaging the
throat packings. When you finish pumping always
follow the Pressure Relief Procedure Warning
elow.
If you are pumping fluid which dries, hardens or sets up,
flush the system with a compatible solvent as often as
necessary to prevent a build up of dried fluid in the
pump or hoses.
Flushing
To reduce the risk of fluid injection injury, static spark-
ing, or splashing, follow the Pressure Relief Pro-
cedure Warning below, and 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.
Lubrication
The accessory air line lubricator (D) provides automatic
air motor lubrication. For daily, manual lubrication,
disconnect the regulator, place about 15 drops of light
machine oil in the pump air inlet, reconnect the regulator
and turn on the air supply to blow oil into the motor.
Every 40 hours of operation, check that the packing nut
is tight. Follow Pressure Relief Procedure Warning
below, first. Tighten just snug—do not overtighten or
the packings may be damaged.

housing (115) and into the intake valve housing
(103). Tighten evenly.
Mount the displacement pump (1) on the tie rods
(10) so the outlet is aligned with the optional outlet
at the base of the motor. Install the riser tube (14), if
used. Install the tie rod locknuts (4) and tighten
evenly. Install the cotter pin (3) and tighten the
coupling nut (9).
Reconnect the grounding wire, if it was discon-
nected during service.
Connect the air supply and run the pump slowly to
check for binding. Adjust the tie rods as necessary.
Tighten the packing nut/wet-cup just enough to
prevent leaking, but no tighter. Overtightening com-
presses the packings and causes leaking.
