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 (15) opens automatically to
prevent overpressurization of the pump.
DThe gun air regulator (J) adjusts the air pressure
to the air-assisted spray gun (106).
DThe air inlet swivel (H) connects incoming air to
the pump and to the gun.
DThe strainer (42) keeps large particles from enter-
ing the pump.
DThe fluid filter (13) 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 agitator (39), included on Models 232443,
232455, 232461, 232467, and 232473 only, keeps
the fluid in suspension.
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.
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.
Packing Nut
Before starting, fill the packing nut 1/3 full with Graco
Throat Seal Liquid (TSL) or compatible solvent. See
your separate pump manual.
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.
Prime the Pump
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 regulator (J), pump air regulator
(G), and bleed-type air valves (B, E).
3. Connect the air line (A) to the air inlet swivel (H).
4. Check that all fittings throughout the system are
tightened securely.
5. Fill the pail (19) with fluid. Make sure the pail cover
(1) is fastened securely to the pail with the screw
knobs (20).
6. Close the fluid drain valve (F). Open the fluid
regulator (201), if present.
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 regulator (J). Slowly open the pump air regula-
tor (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.

Operation
Agitator Operation (Models 232443,
232455, 232461, and 232467 only)
1. Slowly open the control valve (K) to start the
agitator (39). See Fig. 3.
2. Use the valve (K) to adjust the speed. Do not
operate the agitator too fast. If the fluid foams or a
vortex forms on the fluid surface, reduce the speed
of the agitator.
3. Refer to manual 306565 for further agitator operat-
ing instructions.
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.
NOTE: The fluid pressure regulator (201), which is
included on 10:1 and 15:1 Monarks, allows more
precise adjustment of the fluid pressure at the gun.
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 22 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. Shut off the agitator (39), if present. Relieve
the pressure.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 13.

308766 13

10:1 and 15:1 Monarks include a fluid pressure
regulator kit. Refer to page 18 for parts.
If you order a new twin air/fluid hose (101), cut
the coupling off one end of the red air hose so
that the hose is 2 in. (50 mm) longer than the
blue fluid hose. Make sure the cut is straight,
not slanted. Push the cut end of the air hose
into the outlet fitting of the gun air regulator.
