SAFETY WARNINGS
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read And Understand All Instruction Manuals Before Operating Equipment.
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 splashing in the
eyes or on the skin, or other serious bodily injury, or 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 wear protective eyewear , gloves, clothing and
respirator as recommended by the fluid and solvent
manufacturer.
System Pressure
This pump can develop 360 psi (25 bar) MAXIMUM
WORKING PRESSURE, at 180 psi (12 bar) MAXIMUM
INCOMING AIR PRESSURE. Be sure that all spray
equipment and accessories are rated to withstand the
maximum working pressure of this pump.
The MAXIMUM INCOMING AIR PRESSURE to the agitator is 100 psi (7 bar).
DO NOT exceed the maximum working pressure of any
component or accessory used 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 on the back cover. Always read the manufacturer’s literature before using fluid or solvent in this pump.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, 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, cleaning or
changing spray nozzles, and whenever you stop
spraying.
1. Shut off the air to the pump.
2. Close the bleed–type master air valve (required
in your system).
3. Close the pump air valve.
4. Close the pump restrictor valve.
5. Shut off the air to the agitator (if used).
6. Hold a metal part of the spray gun firmly to the
side of a grounded metal pail, and trigger the
spray gun to relieve pressure.
7. Open the drain valve, having a container ready
to catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
HOSE SAFETY
Pressurized fluid in the hoses can be dangerous. If the
hose develops a leak, split or rupture due to any kind of
wear, damage or misuse, the spray emitted from it can
cause serious bodily injury or property damage.
TIGHTEN all fluid connections securely before each use.
Pressurized fluid can dislodge a loose coupling or allow
pressurized spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check
the 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.
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a grounded spray system. An ungrounded or
poorly grounded hose can make your system hazardous.
Refer to FIRE OR EXPLOSION HAZARD section on
page 3.
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.
MOVING PARTS HAZARD
HANDLE AND ROUTE HOSES CAREFULL Y. Do not
pull on hoses to move equipment. Do not use fluids which
are not compatible with the inner tube and cover of the
hose. DO NOT expose Graco hoses to temperatures
above 82 C (180 F) or below –40 C (–40 F).
Moving parts can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting
or operating the pump. Follow the Pressure Relief Procedure, above, to prevent the pump from starting accidentally.
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 for proper grounding. Do not use the system again until the problem has
been identified and corrected.
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 interrupts the grounding continuity.
9. To maintain grounding continuity when flushing or relieving pressure , always hold a metal part of the
spray gun firmly to the side of a grounded metal pail,
then trigger the spray gun.
To ground the pump:
To ground the pump, loosen the grounding lug locknut
(W) and washer (X). Insert one end of a 1.5 mm@ (12
ga) minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig 1. Connect
the other end of the wire to a true earth ground. See
ACCESSORIES on page 17 to order a ground wire
and clamp.
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 instructions for your area and type of equipment. BE SURE to ground all of this spray equipment:

INSTALLATION
NOTE: The reference numbers and letters in parentheses in the text refer to the callouts in the figure
drawings and the Parts Drawing.
The Typical Installation on page 4 is only a guide to selecting and installing required and optional accessories.
For assistance in designing a system to suit your particular needs, contact your Graco representative or Graco
Technical Assistance (see back page).
Accessories
WARNING
A bleed–type master air valve (A) and a fluid drain
valve (B) are required in your system. These accessories reduce the risk of serious bodily injury including 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
trapped between it and the pump after the air 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 spray gun;
triggering the spray gun to relieve pressure may not
be sufficient.
Refer to the Typical Installation drawing on page 4, and
ACCESSORIES on page 17. Be sure the accessories
are adequately sized to meet the system’s requirements.
Mount the pump to suit the type of installation planned.
Be sure the pump is 1/2 in. (13 mm) off the bottom of the
supply container. If the pump is mounted in a ram or an
elevator, refer to the manual supplied with the ram/elevator for installation and operation instructions. The Typical
Installation on page 4 shows the plumbing for an elevator
on each pump.
Install the air line accessories in the order shown in the
Typical Installation drawing. The air line lubricator (S)
provides automatic air motor lubrication. The bleed–type
master air valve (A) is used to relieve air pressure. Be
sure the valve is easily accessible from the pump. The air
filter/regulator assembly (C) filters and regulates the
compressed air. To control pump speed and fluid outlet
pressure, adjust the pump air inlet pressure with the regulator (21) mounted on the pump.
On the fluid line, install a fluid filter (E) with shutof f
valves (F) to isolate it for cleaning. Where the supply and
return lines meet, install a fluid pressure regulator (G). In
a two–pump system, install Y -adapter (H) at the beginning and end of the supply and return lines.
GROUNDING
WARNING
Before operating the pump, ground the system as
explained under FIRE OR EXPLOSION HAZARD
and Grounding on page 3.

contaminated by the oil, flush it out with a compatible solvent before using the pump.
Start and Adjust the Agitator
1. Turn on the main air supply and slowly open the agitator air control valve (78). DO NOT exceed 100 psi
(7 bar) MAXIMUM INCOMING AIR PRESSURE to
the agitator.
2. Use the lowest speed possible to thoroughly agitate
the fluid. If the agitator is operated at too high a
speed, the paint may foam. Agitate the fluid thoroughly before using it.
3. Operate the agitator continuously while you are
spraying or circulating the fluid.
4. Stop the agitator by closing the air control valve (78).
For overnight shutdown, close the main air supply
valve first.
Start and Adjust the Pump

Reference numbers and letters in the text correspond to the callouts in the drawings.
1. Close the pump air regulator (21) and the agitator air
control valve (78).
2. Turn on the main air supply and open the bleed–type
master air valve (A).
6 3. Open the air motor restrictor valve (Q) by turning the
knob counterclockwise as far as possible.
4. Slowly open the pump air regulator (21) until you obtain the desired pump speed and pressure. T o reduce system wear , always use the lowest pump
speed and pressure needed for the results you want.
For example, if 12 psi (0.8 bar) is needed at the last
spray gun, adjust the outlet pressure to 36 psi (2.4
bar).
Adjust the pump air regulator (21) while adjusting the
fluid pressure to maintain pump speed and pressure.
6. When the pump speed and fluid pressure have been
adjusted, tighten the restrictor valve locknut.
7. Trigger the gun until all air has been purged from the
system. The pump will run continuously and speed
up or slow down as supply demands until the air supply is shut off.
When using the pump in a direct supply system:
3. Trigger the gun into a waste container and slowly
open the pump air regulator (21) until you obtain the
desired pump speed and pressure. T o reduce system wear, always use the lowest pump speed and
pressure needed for the results you want.
4. After all the air is purged, close the gun. The pump
will start and stop as the gun is opened and closed.
All systems:
WARNING
To reduce the risk of overpressurizing your system,
which could result in component rupture and cause
serious bodily injury, 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 3.
WARNING
For your safety, NEVER raise the elevator or drum
cover until after the pump and agitator are shut of f
and the pressure has been relieved. Follow the
Pressure Relief Procedure Warning, above.
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. 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, refill the container
and prime the pump and the lines with fluid, or flush and
leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.
MAINTENANCE
Shutdown and Care of the Pump
For overnight shutdown, follow the Pressure Relief Procedure Warning, below.
Always stop the pump at the bottom of the stroke to prevent the fluid from drying on the exposed displacement
rod and damaging the throat packings.
