System Accessories
WARNING
Figure 1 is only a guide to selecting and installing
optional and required accessories. For help in design-
ing a system to suit your needs, contact your Graco
distributor.
To reduce the risk of serious injury including skin
injection, splashing in the eyes or on the skin, and
injury from moving parts, if you are adjusting or
repairing the pump, two accessories are required
in your system: a bleed-type master air valve (F)
and a pressure drain valve (L).
Mount the pump to suit the type of installation planned.
See page 23 for dimensions and mounting hole layout.
The bleed-type master air valve (F) relieves air
trapped between it and the air motor after the air
supply is shut off. Trapped air can cause the air
motor to cycle unexpectedly if you are adjusting or
repairing the pump. Install the valve near the pump
air inlet, within easy reach of the pump.
The pressure drain valve (L) assists in relieving
fluid pressure in the displacement pump, hoses
and gun. Triggering the spray gun to relieve pres-
sure may not be sufficient.

tion to a properly grounded fluid hose and pump.
D Object being sprayed: according to local code.
D Fluid supply container: according to local code.
D All solvent pails used when flushing or relieving
pressure, always hold a metal part of the gun firmly
to the side of a grounded metal pail, then trigger the
gun.
D An air line lubricator (G) provides automatic air
motor lubrication.
D A bleed-type master air valve (F) relieves air
trapped between it and the motor when the valve is
closed. Order Part No. 107142.
To ground the pump:
D The air regulator (E) controls pump speed and
pressure.
To ground the pump, use a ground wire and clamp as
shown below. Remove the ground screw (Z) and insert
through the eye of ring terminal at end of ground wire
(Y). Fasten the ground screw back onto the pump and
tighten securely. Connect the other end of the ground
wire to a true earth ground. See Fig. 2. To order a
ground wire and clamp, order Part No. 222011.
D An air line filter (D) removes harmful dirt and
contaminants from your compressed air supply.
D A drain valve (L) is required near the pump fluid
outlet to relieve fluid pressure in the pump, hose
and gun. Order Part No. 210657.
D Install an electrically conductive fluid hose (M) and
spray gun (N).
Grounding
Z

Operation
Pressure Relief Procedure
WARNING
Never operate the pump with the warning plate
(20) or the identification plate (40) removed. These
plates protect your fingers from pinching or am-
putation by moving parts in the air motor.
WARNING
SKIN 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:
Starting and Adjusting the Pump
1. With the air regulator (E) closed, open the bleed-
type master air valve (F).
D are instructed to relieve the pressure,
D stop spraying,
2. Connect the air hose.
D check or service any of the system equipment,
D or install or clean the spray tips.
1. Lock the spray gun trigger safety.
3. Trigger the spray gun (N) into a grounded metal
pail, making firm metal-to-metal contact.
2. Close the pump air regulator. Close the bleed-type
master air valve (required in your system).
4. Open the pump air regulator (E) slowly, just until
the pump is running. When the pump is primed
and all air has been pushed out of the lines, re-
lease the spray gun trigger. With sufficient air
supplied, the pump starts when the spray gun is
triggered and shuts off when the trigger is re-
leased.
3. Unlock the gun trigger safety.
4. Hold a metal part of the spray gun firmly to a
grounded metal waste container and trigger the
gun to relieve the fluid pressure.
5. Lock the gun trigger safety.
6. Open the pump drain valve (required with your
system) and leave it open until you are ready to
spray again.
5. Adjust the air regulator just until you get adequate
flow from the spray gun. Always run the pump at
the lowest speed necessary.
If you suspect that the spray tip or hose is clogged or
that fluid pressure is not fully relieved after following
the steps above, very slowly loosen the tip guard
retaining nut or hose end coupling and relieve pressure
gradually. Clear the tip or hose obstruction.
CAUTION
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 lines with fluid, or flush it and leave it filled
with a compatible solvent. Be sure to eliminate all air
from the fluid lines. Use a pump runaway valve (K) to
automatically shut off the pump if it starts to run too fast.
WARNING
COMPONENT RUPTURE HAZARD
Overpressurizing any component can
result in rupture, fire, explosion, property
damage, and serious injury. To reduce
the risk of overpressurizing, know the Maximum
Working Pressure of the lowest rated component in
your system, and limit the air to the pump so that
you never exceed that pressure.
6. Read and follow the instructions supplied with
each component in your system.
To determine the fluid output pressure using the air
regulator reading, multiply the pump ratio by the air
pressure you set on the regulator gauge. Example:
7. If the pump will be unattended for any period of
time, or to shut off the system at the end of the
work shift, always follow the Pressure Relief
Procedure, at the left.
15 (:1) ratio x 100 psi air = 1500 psi fluid output
[15 (:1) ratio x 7 bar air = 105 bar fluid output]

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
PISTON
WARNING
Keep your hand and fingers away from the piston
when it is moving. As the piston moves into the
pump base it can amputate fingers or break tools
caught between the moving parts. Note the pinch
point shown in Fig. 3. Be sure all air and fluid
pressure is fully relieved before adjusting the piston
or packing nut to reduce the risk of amputation.

stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,

in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.

NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
