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. Spray from
the gun, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including theneed 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 part of the
body. NEVER put hand or fingers over the spray tip.
ALWAYS have the tipguard 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 tostop 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 yourskin, get EMERGENCY
MEDICAL CARE AT ONCE. DO MOT 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 injury
the 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. Consultarion with a plastic
surgeon or reconstructive hand surgeon may be advisable.
S p r a y G u n S a f e tDevices
y
Be sure all gun safety devices are operating properly before
each use. Do not remove or modifyany part of the gun; this
can cause a malfunction and result inserious bodily injury.
Safety Latch
Whenever you stopspraying, even for a moment, always set
the gunsafety latch in the closed or "safe" position, making
the gun inoperative. Failure to set the safety latchcan result in
accidental triggering of thegun.
Diffuser
The gun diffuserbreaks up spray and reduces the risk of fluid
injection when the tip
is not installed. Check diffuser operation
regularly. Follow the Pressure Relief Procedure, below,
J
mp.,
m&&
then remove the
spray tip. Aim the gun into
a grounded metal
pail, holding the gun firmly to the
pail. Using the lowest possible pressure, trigger the gun. the
If fluid emittedisnotdiffused
into an irregular stream, replace the diffuser immediately.
Tip Guard
ALWAYS have the tip guard in place on the spray gun while
spraying. The tipguard alertsyou t o the fluid injectionhazard
and helps prevent accidentally placing your fingers
or any part
of your bodyclose t o the spray tip.
Trig er Guard
NEVER operate the gunwith the trigger guard removed. The
trigger guard reduces the risk of accidentally triggering the
gun if it is droppedor bumped.
S p r a y Tip S a f e t y
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs whilespraying. engage the gunsafety latch
immediately. ALWAYS follow the Pressure Relief Procedure and then removethe spray tip to clean it.
NEVER wipe off build-up aroundthe spray tip untilpressure is
fully relieved and the gun safety latch is
engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injection, splashing in theeyes or onthe skin, or injury from moving parts, always follow this procedurewhenever you shut off
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. Shut off the air to thepump.
3. Close the bleed-type master air valve (required in your
system).
4. Disengage the gunsafety latch.
5. Hold a metal part of the gunfirmly to theside ofa grounded metal pail, and trigger the gun t o relieve pressure.
6. Engage the gunsafety latch.
7. Open the drain valve (required in your system), having a
grounded metal 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 hoseis completely clogged,
or that pressure has not been fully relievedafter followmg the
steps above, VERY SLOWLY loosen the tip guard retaining
nut or hose end coupling 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 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, explosionor property damage.
NEVER alter or modify any part of this equipment; doing so
could cause it t o malfunction.
System Pressure
The 3O:l pump develops 36ao psi I250 bar1 MAXIMUM
WORKING PRESSUREat 120 psi (8 bar) air pressure. NEVER
exceed 120 psi 18 bar1 air supply pressure to the pump.
Be sure a11 system components and accessories are rated to
withstand the maximum working
pressure of the pump. DO
NOT exceed the maximum workingpressure of any component or accessory used in your system.
Fluid Compatibility
BE SURE that all fluids andsolvents used arechemically compatible with the wettedparts shownin the Technical Data on
the back cover. Always read the manufacturer's literature
Read and follow the fluid solvent manufacturer's literature
regarding the use of protective clothing and equipment. before using fluid
or solvent in this pump.

FIRE
~~
OR EXPLOSlON HAZARD
Static electricity is created by the high velocity flow of fluid
through the pumpand hose. If every part of thespray equipment is not properly grounded, sparking may occur, and the
system may become hazardous. Sparking may also occur
when pluggingin or unplugging a power supplycord. Sparks
can ignite fumes from solvents and the fluid beingsprayed,
dust particles and otherflammable substances, whether you
are spraying indoorsor outdoors, and can causea fire or explosion and seriousbodily injury and property damage.
7.
A l l solvent pails used whenflushing. according to local
code. Use only metalpails, which are conductive. Do not
place the pail onp non-conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.
8.
To maintain grounding continuity when flushing orrelievingprassure, always hold a metal partof the gun firmly to
the sideof a metal pail, then trigger thegun.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING/DISPENSING IMMEDIATELY. Check the entire svstem

has
been identified and corrected.
~
~~
Grounding
To reduce the risk of static sparking, ground the pumpand all
other componentsused or located in thespray area. CHECK
your local electrical codefor detailed grounding instructions
for your area and typeof equipment andbe sure to grounda11
of these components:
1.
Pump: use ground wire and clamp as shown inFig 1
2.
Air andfluid hoses: use only groundedhoses with a maximum of 500 feet 1150 m) combined hose length toensure grounding continuity. Refer to Hose Grounding
Contlnuity.
3.
Air compressor: follow air compressor manufacturer's
recommendations.
4.
Spray gun or dispensing valve: obtain grounding through
connection to a properly grounded fluidhose and pump.
5.
Obiect being spreyed: according to local code.
6.
Fluidsupply container: according to local code.
~
High pressure fluid in the
hoses can bevery dan erous If the
hose develops a leak, split or rupture due to any f i n d oi wear,
damage or misuse,the highpressure spray emitted from itcan
cause a fluid injection injury or other serious bodily injury or
property damage.
The
ALL FLUID HOSES MUST HAVE SPRING GUARDS1
spring guards help protect
the hose from kinks or bends a t or
close to thecoupling which can result in hose rupture.
TIGHTEN a11 fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from thecoupling.
NEVER use a damaged hose. Before each use, check entire
hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of thehose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose or mendit withtape or any other device. A
repaired hose cannot contain the high pressure fluid.
~~
~~
To ground the pump, loosen the grounding lug locknut (A)
minimum
and washer 10). Insert one end of a 12 ga (1.5 mm21
ground wire (Dl into the slot in lug IC1 and tighten locknut
securely. See Fig 1. Connect the other end of the wire t o a
true earth ground.Refer t o page 13to order a ground wire and
clamp.
Flushing S a f e t y
Before flushing, be sure the entire system and flushing pails
are properly grounded. Refer to Grounding, above. Follow
the Pressure Relief Procedure on
page 2, and remove the
spray tip from the gun. Always use the lowest possible fluid
pressure, and maintain firm metal-to-metal contact between
the gun andthe pail during flushingto reduce the risk of fluid
injection injury. static sparkingand splashing.
HANDLE ANDROUTE HOSES CAREFULLY. Do not pullon
hoses to move equipment. Do not use fluids or solvents which
are not compatible with theinner tube andcover of thehose.
DO NOT expose Graco hose to temperatures above 1 W F
182"Cl or below -40°F 1-40"C).
Hose Grounding Continuity
Proper hosegrounding continuity isessential t o maintaining a
grounded spray system. Check the electricalresistance of your
air and fluidhoses at least once a week. If yourhose 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 theappropriate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace it immediately. An ungroundedor poorly groundedhose canmake
your system hazardous. Also read FIRE OR EXPLOSION
HAZARD, above.
MOVING PARTS HAZARD
The piston in the air motor, located behind the air motor
shield, moves whenair is supplied to the motor. Moving parts
can pinch or amputate your fingers or other body parts.
Therefore, NEVER operate the pump withthe air motor shield
removed. KEEP CLEAR of moving parts when starting or
operating the pump. Before checkingor servicing the pump,
follow the Pressure Relief Procedure
on page 2 to prevent
the pump from starting accidentally.
IMPORTANT
United States Government safety
standards have been adopted under the Occupational Safety and Health
Act. These standards-particularly the General Standards, Part 1910, and the Construction Standards, Part 1926-should be consulted.

OPERATION
WARNING
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 the Pressure Relief Procedure
on page 2
when checking orservicing any pan of thespray
system, when installing, cleaning or changing
spray tips, and whenever you stop spraying.
Flush the Pump Before Using
Pumps are tested with lightweight motor oil which is
left into protect the pump
parts. To prevent contamination of the fluid, flush the pump with a compatible solvent before using it. If the pump
is being usedto supply
a circulating system, allow the solvent to circulate until
the pumpis thoroughly flushed.
WARNING
Before flushing, be sure the entire system and
flushing pails are properly grounded. Refer to
Grounding on page 3. Follow the Pressure
Relief Procedure on page 2, and remove the
spray tip from the gun. Always use the lowest
possible fluid pressure, and maintain firm metalto-metal contact betweenthe gun and the pail
during flushing to reduce the risk of fluid injection
injury, static sparking and splashing.
MAINTAIN FIRM
METAL-TO-METAL
CONTACT BETWEEN
U N A N 0CONTAINER
Starting and Adjusting Pump
Trigger the spray gun and slowly open the air supply
valve until the pump
starts, about 40 psi (3 bar). Allow
the pump to cycle slowly until all the air is pushed out of
the lines. Releasethe trigger; the pump willstall against
the pressure.
With the pump
and lines primed, andwith adequate air
pressure and volume supplied, the pump will startand
stop as the spray gun is triggered and released. In a circulating system, it will runcontinuously and speed up or
slow down as supply demands until the air supply is
shut off.
Use an adequately sized air regulator to control the
pump speed and fluid pressure. See ACCESSORIES,
page 13. Always use the lowest air pressure necessary
to obtain the desired results. Higher pressures waste
fluid and cause premature wearof the pumppackings
and spray tip.
Keep the wet-cup136) filled with Graco Throat Seal Liquid (TSL) tohelp prolong the packing life. Check the
tightnessof the packing nut 136) weekly. The packing
nut should be tight enough to prevent leakage-no
tighter. See Fig 2. Always follow the Pressure Relief
Procedure on page 2 before adjusting the packing nut.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. (A pump runaway
valve automatically alerts you to this problem, see INSTALLATION.) Ifyour pump accelerates quickly, or is
running too fast, stop it immediately and checkthe fluid
supply. If thesupply containeris empty and air has been
pumped into the lines, refill the supplycontainer and
prime the pump and lines with fluid, being sure to
eliminate all air from fluid system, or flush the pumpas
described in "Shutdown and Care", below.
Shutdown andCare of Pump
Always follow the Pressure Relief Procedure, on
page 2, whenever you shut off the pump. Stop the
pump a t the bottom ofits stroke to keep fluid from drying on the exposed displacement rod and damaging
throat packings.
Always flushthe pump witha compatible solvent before
the fluid can dry on the displacement rod.At the end of
each day, if you are pumping water based fluid, first
flush with water, then withmineral spirits to protect the
pump parts. Relieve pressure and leave the mineral
spirits in the pump to
prevent corrosion.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injection,splashing in the eyes oron
the skin, or injury from moving parts, always
follow this procedurewhenever you shut off the
pump, when checkingor servicing anypart of the
system, when installing, cleaning or changing
spray tips, and whenever you stopspraying.
