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 fluidpressure. Sprayfrom
the aun. leaks or ruDtured ComDonentS 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 on the skin can
cause serious damage.
NEVER point the spray gun at anyone or at any pert of the
body. NEVER put hand or fingers over the spray tip. NEVER
try to "blow back" paint; this is NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYS follow the Pressure Relief Procedure, below.
before cleaning or removing the spray tip or servicing any
system equipment.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment safety devices are operating properly
before each use.
M e d i c a l Alert-Airless S p r a y Wounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT
ONCE. DO NOT TREATA S 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
es 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.
Spra y Gun S a f e t y D e v i c e s
Be sure all gun safety devices are operating properly before
each use. Do notremove or modify any part of the gun; this
can cause amalfunction and result in serious bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, alwaysset
the gun safety latch in the closed or "safe" position, making
the guninoperative. Failureto set the safety latch can result in
accidental triggering of the gun.
Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid
injection when thetip is not installed. Checkdiffuser operation
regularly. Follow the Pressure Relief Procedure, below,
then remove the spray tip. Aim the gun into a metal pail,
holding the gun firmlyto the pail. Using the lowest possible
pressure, trigger the gun. If the fluidemitted is notdiffused into en irregular stream, replacethe diffuser immediately.
Tip Guard
ALWAYS have the tipguard in place on the spray gun while
spraying, The tip guard alerts you to the fluidinjection hazard
and helps prevent accidentally 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
auard reduces the risk of the aun
t r i w x i n a- accidentallv if it is
aropped or bumped.

"
S p r a y Tip S a f e t y
use enremecaution when cleaning or changing spray tips. If
the spray tip clogs whde spraying, engagethe gunsafety latch
immediately. ALWAYS follow the Pressure Relief Procedure and then remove the spray tip to clean it.
NEVER wipe off build-up around the spray tip until pressure is
fully relieved end the gun safety latch is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injec-
tion, splashing in theeyes or on theskin, or injury from moving parts, always follow this procedure whenever you shutoff
the pump, when checking or servicing any part of the spray
system. when installing, cleaning or changing spray tips, and
whenever you stop spraying.
1. Engage the gun safety latch.
2. Turn off the air to the pump.
3. Close ths bleed-type master air valve(requiredl.
4. Disengage the gun safety latch.
5. Hold a metal part of the gun firmlyto the side of a grounded metal pail, and trigger the gun into the pail to relieve
pressure.
6. Engage the gun safety latch.
7. Open the pump drain valve (required) and leave open until
you are ready to spray again.
If you suspect that the spray tip or hose is completely dogged,
or thatpressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen the tip guard retaining
nut or hose endcoupling and relieve pressure gradually,then
loosen completely. Now clear the tip or hose.
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or eccessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them t o rupture and result in fluid injection or other
serious bodily injury, fire. explosion or propew 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.
Read and follow the fluid and solvent manufacturers' literature
regarding the use of protective clothing.

System Pressure
This pump can develop m p s i I210 bar) MAXIMUM WORKING PRESSURE a t 100 psi 17 bar) MAXIMUM incoming air
pressure. Be sure that all spray equipment and accessories are
rated to withstand the maximum working pressure of this
pump. DO NOT exceed the maximum working pressure of any
component or accessory usedin the system.
BE SURE that all fluids and solvents used are chemically compatible with the wetted
parts shown in the Technical Data on
the back cover. Always read the fluid and solvent menufacturer's literature before using them in this pump.
~~~
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 the
system may become hazardous. Sparking may also occur
when plugging in or unplugginga 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.
7.
TOmaintain grounding continuitywhen flushing orrelievingpressure, always hold a metal part of the gun firmlyt o
side of a metal pail, then trigger the gun.
If you experience any static sparking or even a slight shock
while using the equipment, STOP SPRAYING- IMMEDIATELY. Check the entire system for positive grounding. Do not use the system again until the problem has been
identified and corrected.
Groundin
To reduce t f e 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 instructions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1.
Pump: by using a ground wire and clamp as shown in
Fig 1.
2.
Air andfluid hoses: use only grounded hoses with a maximum of 500 feet 1150 m l combined hose length to ensure grounding continuity. Refer to Hose Grounding
Continuity.
3.
Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer. page
4.
Fluid supply container: according to local code.
5.
Object being sprayed: according to local code.
6.
A l l solvent pails used when flushing, according to local
code. Use only metalpails, which are conductive placed
on a positively grounded surface. Do not place the pail on
a non-conductive surface, such as paper or cardboard,
which interrupts the grounding continuity.
~i~1
To ground the pump, loosen the grounding lug locknut I AI
and washer ( 8 ) . Insert one end of a 12 ga 11.5 mm')
minimum, ground wire (D) into the slot in lug IC)and tighten
the locknutsecurely. See Fig 1. Connect the clamp end of the
ground wire to a true earth ground. See ACCESSORIES on
page 14 to order a ground wire and clamp.
Flushin S a f e t y
Reduce #e risk of fluid injection injury, static sparking, or
splashing by following theflushing procedure given on page 6
of this manual. Follow the Pressure Relief Procedure on
2, and remove the spray tip before flushing. Hold a metal
part of the gun firmlyto the side of a grounded metel pail and
use the lowest possible fluid pressure during flushing.
HOSE SAFETY
pq3
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupturedue to any kind of wear,
damage or misuse,the highpressure sprayemitted from it can
cause an injection injury or other serious bodily injury or property damage. have
ALL FLUID HOSES MUST HAVESPRING GUARDS1The
spring guards helpprotect 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 ailow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before eachuse, 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 torecouple
high pressure hose ormend it with tape or anyother device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY.Do not pull on
hoses t o move equipment. Do not use fluids or solvents which
are not compatible with the inner tube and coverof the hose.
DO NOT expose Graco hose to temperatures above 180°F
182OCJ or below -4OOF (-4OPCJ.
Hose G r o u n d i n g Continuity
Proper hosegrounding continuity isessential to maintaining a
grounded spray system. Check the electrical resistanceof your
air andfluid hoses at least once a week. If your hose doesnot
a tag on it which specifies the maximum electrical
resistance, contact the hose supplieror manufacturer for the
maximum resistance limits. Use a voltage meter in the appropriate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace it irnmediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also read FIRE OR EXPLOSION
HAZARD, above.
MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers or other
body parts. The piston in the air motor, located behind the air
motor shield, moves when air is supplied tO the motor. NEVER
operate the pump with the air motor shield removed. Keep
fingers clear of the intake valve or elbow while the pump is
operating, to reduce the risk of amputation or injury to your
hand or fingers. Before checking or servicing the pump,
always disconnect the power source and relieve pressure,
follow the Pressure ReliefProcedure onpage 2, to prevent
the pumpfrom starting accidentally.
IMPORTANT
United States Government safety standards have beenadopted under the Occupational Safety and Health Act. These standards-particularly the General Standards, Part 1910, and the Construction Standards, Part 1926-should be consulted.

WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injection, splashing in theeyes or on
the skin orinjury from moving parts, alwaysfollow
the Pressure Relief Procedure on page 7
whenever you shutoff the pump, when checking
or servicing any partof thespray system,when installing, cleaning or changing spray tips, and
whenever you.stop spraying.
supply. If the supply container is empty and air has been
pumped into thelines, fill thecontainer, prlmethe pump
and lines with fluid, or flush and leave filled with compatible solvent.Be sureto eliminate all air from thefluid
system.
Flush the Pump Before Using
Pumps are tested
with light weight oil which is left in to
protect pumppa%s. To prevent contaminationof fluid,
flush the pump wlth a compatible solvent before using
it. Before flushing, follow the Pressure Relief Procedure, above, and be sure to remove the spray tip
from the gun, if used. Hold a metal part of the gunfirmly to the side of a grounded metal pail and use the
lowest possible pressure during flushing.If the pumpis
being used to supply a circulating system, allowthe solvent to circulate long enough to thoroughly flush the
pump and fluid lines.
Starting and Adjusting the Pump
Fill the wet-cup(36) one-half full withGraco ThroatSeal
Liquid (TSL). Trigger the gun into a grounded metal
pail, and slowly open
the air supply valveuntil thepump
starts [about 20 psi (1.4 bar)]. Allow the pumpto cycle
slowly until all the air is pushed out of thelines. Release
the trigger; the pump will stall against the pressure.
Engage the trigger safety latch.
With the pump and lines primed, and
with adequate air
pressure and volume supplied,the pump willstart and
stop as the gun is triggered and
released. In a circulating
system, it will run continuously and speedup or slow
down as supply demandsuntil the air supply is
shut off.
~~
Check Valve Adjustment
For Displacement Pump 217-773
The intake check valve (39) set
is for the high flow rate
or high viscosity fluids. To set the valve for lighter
viscosity fluid or lowerflow rate, to minimize surgingat
the pump stroke change over, move the ball stop pin
(33)to a lower set of holes, decreasingthe check ball
travel. The piston check valve in this pump is not adjustable. See Fig 2. Refer to SERVICE SECTION for
disassembly instructions.
Use the air regulatorto control pumpspeed and fluid
pressure. See ACCESSORIES. Always use the lowest
air pressure necessaryto give youthe results youwant.
High pressures may waste paint and cause the gun
spray tip and pump to wear faster.
WARNING
To reduce the risk of serious bodily injury, including fluid injection and splashing in the eyes,
and property damage, never exceedthe maximum
air and fluid working pressure of the lowestrated
component in your system. See EQUIPMENT
MISUSE HAZARD, Svatem Pressure,D a m 2.
For Displacement Pump 217-530
The piston andintake check valves (37,39) are set for
high flowrate orhigh viscosity fluids. To set
the valves
for lighter viscosityfluid or lower flow rate to minimize
surging at pump stroke change over, movethe ball stop
pins (26, 33) to a lower set of holes, decreasing the
check ball travel. See Fig 2 and Detail A. Refer
to SERVICE SECTION for disassembly instructions.
Keep the wet-cup(36) filled with Graco Throat Seal Liquid (TSL), and check the tightness of the packingnut
weekly. The packingnut should be tight enough to prevent leakage-no tighter. See Fig 2. Always follow the
Pressure Relief Procedure, above, before adjusting
the packing nut.
Never allow the pump to rundry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damagingitself. (A pump runaway valve
automatically alerts you to this problem, see INSTALLATION.) If your pump accelerates quickly, or is
running too fast, stop it immediately, and checkthe fluid

Shutdown andCare of the Pump
For overnight shutdown, follow the Pressure Relief
Procedure, above. Always stop the pumpat the bottom ofits stroke to keep fluid from drying on the exposed displacement rod and damaging throat packings.
Always flush the pump before the fluid dries on the
displacement rod. Never leave water or water-based
fluid in thepump overnight. First flush with water or a
compatible solvent, then with mineral spirits. Relieve
pressure, but leave the mineral spirits in the pump to
protect parts from corrosion.
