WARNING
A red-handled bleed-type master air valve (E) and
a fluid drain valve (F) are supplied. These compo-
nents help reduce the risk of serious injury, includ-
ing fluid injection and splashing of fluid 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 this valve and the pump after the valve is
closed. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
DThe red-handled bleed-type master air valve (E)
is required in your system to relieve air trapped
between it and the air motor and gun when the
valve is closed (see the WARNING above). Do not
block access to the valve.
DThe pump air regulator (G) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
DThe air relief valve (H) opens automatically to
prevent overpressurization of the pump.
DThe gun air filter/regulator (J) adjusts the air
pressure to the air-assisted spray gun (106).
DThe air inlet swivel (K) connects incoming air to
the pump and to the gun.
DThe suction tube (27) and strainer (28) allow the
pump to draw fluid from a 5 gallon (19 liter) pail (L).
The strainer keeps large particles from entering the
pump. Refer to the parts drawing on page 14.
DThe fluid filter (23) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump. It also includes
the fluid drain valve (F), which is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
DThe air-assisted spray gun (106) dispenses the
fluid. The gun houses the spray tip (107), which is
available in a wide range of sizes for different spray
patterns and rates of flow.
DThe twin hose (101) includes a gun air supply
hose (101a) and a gun fluid supply hose (101b).
The fluid whip hose (103) allows greater gun
maneuverability.
DThe gun filter/swivel (104) provides a final filtering
of fluid before it enters the gun, and allows greater

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tip.
1. Lock the gun trigger safety.
2. Close the red-handled bleed-type master air valve
(E, required in your system). See Fig. 3.
3. Unlock the gun trigger safety.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
5. Lock the gun trigger safety.
6. Open the drain valve (F, required in your system),
having a container ready to catch the drainage.
7. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following 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.
Packing Nut
Before starting, fill the packing nut (M) 1/3 full with
Graco Throat Seal Liquid (TSL) or compatible solvent.
See Fig. 3.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then torque
the nut as specified in your separate pump manual. Do
this whenever necessary. Do not overtighten the
packing nut.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 13.
Prime the Pump
CAUTION
To avoid tip-over, the cart must be on a flat and level
surface. Failure to follow this caution could result in
injury or equipment damage.
1. See Fig. 3. Remove the tip guard and spray tip
from the gun (106). Refer to the gun manual.
2. Close the gun air filter/regulator (J), pump air
regulator (G), and bleed-type air valves (B, E).
3. Close the fluid drain valve (F).

Operation
Prime the Pump (continued)
7. Hold a metal part of the gun (106) firmly to the side
of a grounded metal pail and hold the trigger open.
8. Open the bleed-type air valves (B, E) and the gun
air filter/regulator (J). Slowly open the pump air
regulator (G) until the pump starts.
9. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
10. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
11. If the pump fails to prime properly, open the drain
valve (F). Use the drain valve as a priming valve
until the fluid flows from the valve. Close the valve.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (F) to
help prime the pump and vent air before it enters the
hose. Close the drain valve when all air is eliminated.
Install the Spray Tip
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Relieve the pressure. Install the spray tip and tip guard
as explained in your separate gun manual, supplied.
The fluid output and pattern width depend on the size
of the spray tip, the fluid viscosity, and the fluid pres-
sure. Use the Spray Tip Selection Chart in your gun
instruction manual as a guide for selecting an
appropriate spray tip for your application.
Adjust the Spray Pattern
1. Start the pump. Use the pump air regulator (G) to
adjust the pump speed and fluid pressure until the
spray is completely atomized. Use the lowest
pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip and pump wear.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your package, which could cause com-
ponent rupture and serious injury, never
exceed 100 psi (0.7 MPa, 7 bar) air input pressure
to the package. Never exceed 100 psi (0.7 MPa, 7
bar) air input pressure to the spray gun. Also refer
to the Technical Data on page 18 and to your sep-
arate component manuals.
2. When applying the fluid, keep the gun a consistent
distance, about 8 to 12 inches (200 to 300 mm)
from the surface of the object being sprayed.
Always hold the gun at a right angle from the
surface. Do not make an arc with the gun, as it
causes an uneven coat of fluid. Use a full-open,
full-close triggering action. Practice to find the best
length and speed of stroke.
3. To adjust the spray pattern, follow the instructions
in your gun manual, supplied.
4. With the pump and lines primed, and with ade-
quate air pressure and volume supplied, the pump
will start and stop as you open and close the gun.
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
Shutdown and Care of the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 13.

308763 13
