The Typical Installation above is only a guide to select-
ing and installing accessories. For assistance in de-
signing a system to meet your needs, contact your
Graco distributor.
The Dimensional Drawings on page 18 provide neces-
sary measurements for mounting the pump. If you use
an accessory ram (G), as shown in the Typical Installa-
tion, refer to the separate ram manual for mounting
dimension requirements.
System Accessories
Install the air line accessories in the order shown in the
Typical Installation. Working upstream from the pump
air inlet, install an air line lubricator (E) for automatic
air motor lubrication, a bleed-type master air valve (D)
to relieve air trapped between the valve and the pump,
and an air regulator (C) to control pump speed. Install
a pump runaway valve (F) to shut off the air to the
pump if the pump accelerates beyond the preadjusted
setting. A pump which runs too fast can be seriously
damaged.
Install an air line filter (B) to remove harmful dirt and
moisture from the compressed air supply, and a sec-
ond bleed valve (J) to isolate the accessories for
servicing. Be sure the pump air line (A) is properly
grounded, and is large enough to supply an adequate
volume of air to the motor.
WARNING
A bleed-type master air valve (D) and a fluid drain
valve (H) are required in your system. These
accessories help reduce the risk of serious injury
including fluid injection, 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 this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly . Position 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.
On the pump fluid line (M), install a fluid drain valve (H)
close to the pump fluid outlet.
NOTE: To use the optional fluid outlet at the base of
the air motor, connect a riser tube between the stan-
dard outlet and the optional outlet.
On models 949444 and 954180 only, connect the air
exhaust hose (K) and muffler (L) to the air motor.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause seri-
ous injury. To reduce the risk of an injury
from injection, splashing fluid, or moving parts, fol-
low the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying/dispensing,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips/nozzles.
1. Lock the gun/valve trigger safety.
2. Shut off the air to the pump.
3. Close the bleed-type master air valve (required in
your system).
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve trigger safety.
7. Open the drain valve and/or the pump bleeder
valve (required in your system), having a container
ready to catch the drainage.
8. Leave the drain valve open until you are ready to
dispense 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, then clear
the tip or hose.
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers or other body parts. When the
pump is operating, the priming piston
(located at the pump intake) and the air motor pis-
ton (located behind the air motor shield) move.
Therefore, never operate the pump with the air mo-
tor shield removed, and keep your fingers and
hands away from the priming piston.
Before attempting to clear an obstruction from the
priming piston or service the pump, relieve the
pressure to prevent the pump from starting acci-
dentally.
Flush the Pump Before Using
This pump was tested with water, and some of it may
still be in the pump. If the water will contaminate the
fluid you are pumping, flush it out with a compatible
solvent before using.
Keep the packing nut/wet-cup (45) one-half full with
Graco Throat Seal Liquid (TSL), to help prevent the
fluid being pumped from drying on the displacement
rod and damaging the packings. See Fig. 3. Do not
use TSL with food or sanitary applications.
Starting and Adjusting the Pump
1. Make sure the air regulator (C), drain valve (H),
and pump bleeder valve plug (52) are closed.
2. Open the bleed-type master air valve (D).
3. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve.
4. Slowly open the air regulator (C) until the pump
starts running slowly (about 20 psi [1.4 bar,
0.14 MPa]). Run the pump slowly until all the air is
purged from the pump and lines.
5. If the pump is not priming properly, open the
bleeder valve plug (52) slightly. Use the bleed hole
on the underside of the valve body (50) as a
priming valve until the fluid appears at the hole.
Close the plug (52).
WARNING
To reduce the risk of fluid injection, do not use your
hand or fingers to cover the bleeder hole when
priming the pump.

9306916
Operation
6. Release the trigger and lock the trigger safety. The
pump will stall against pressure.
7. In a direct supply system, the pump will start and
stop as the gun/valve is opened and closed. In a
circulating system, it will run continuously and
speed up or slow down as the system demands.
Always use the lowest pressure necessary to
obtain the desired results.
WARNING
To reduce the risk of serious injury, including fluid
injection and splashing in the eyes or on the skin,
and property damage, never exceed the maximum
air and fluid working pressure of the lowest rated
component in your 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 8.
Relieve the pressure. Whenever you shut off the
pump. Stop the pump at the bottom of its stroke to
keep fluid from drying on the exposed displacement
rod and damaging the throat packings.
Every 40 hours of operation, check that the packing
nut/wet cup is tight. Relieve the pressure and tighten
the nut just snug – do not overtighten, or the packings
may be damaged.
Always flush the pump before the fluid dries in the
pump and hoses. If the pump is to be stored for any
period of time, and you are pumping water-based fluid,
first flush the pump with water, then with mineral spirits
to protect the pump parts.
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 acceler-
ates 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, prime
the pump and the lines with fluid, or flush the pump
and leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
NOTE: A pump runaway valve (F) can be installed on
the air line to automatically shut off the pump if it starts
to run too fast.
Flushing
To reduce the risk of fluid injection injury, static spark-
ing, or splashing in the eyes or on the skin, relieve the
pressure, and remove the spray tip (spray guns or
spray valves only) before flushing. Hold a metal part of
the gun/valve firmly to the side of a grounded metal
pail and use the lowest possible fluid pressure during
flushing.
Lubrication
The accessory air line lubricator (E) provides automat-
ic air motor lubrication. For daily, manual lubrication,
disconnect the air supply, place about 15 drops of light
machine oil in the pump air inlet, and reconnect the air
supply to blow oil into the motor.
