-
Be sure that all spray/dispensing equipment and accessories are rated to
withstand the maximum working pressure of the pump. DO NOT exceed
the maximum working pressure of any component or accessory used in
the system.
NEVER alter or modify any part of this equipment; doing so could cause it
to malfunction.
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 Al-
ways read the manufacturer

HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the hose devel
ops a leak, split or rupture due to any kind of wear, damage or misuse, the
high pressure spray emitted from it can cause a fluid injection injury or
other serious bodily injury or property damage.

(–40_ F).
ALL FLUID HOSES USED WITH A FLEXING MOTION MUST HAVE
SPRING GUARDS ON BOTH ENDS! The spring guards help protect
the hose from kinks or bends at or close to the coupling which can result
in hose rupture.
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a grounded
spray system. 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 speci

Also, read FIRE OR EXPLOSION HAZARD, below
.
.
DO NOT try to recouple high pressure hose or mend it with tape or any
other device. A repaired hose cannot safely contain the high pressure
fluid.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose.
If every part of the spray/dispensing 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
Grounding
To reduce the risk of static sparking, ground the pump, object being
sprayed, and all other spray/dispensing equipment used or located in the
spray/dispensing 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/dispensing equipment:
particles and other flammable substances, whether you are spraying/dis
pensing indoors or outdoors, and can cause a fire or explosion and seri
ous bodily injury and property damage. Do not plug in or unplug any
power supply cords in the spray/dispensing area when there is any

nection to a properly grounded fluid hose and pump.
To ground the pump:
6. Fluid supply container: according to your local code.
7. Object being sprayed: according to your local code.
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 16 to order a ground wire and clamp.
8. All solvent pails used when flushing, according to your local code.
Use only metal pails, which are conductive, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as

Flushing Safety
Before flushing, be sure the entire system and flushing pails are properly
grounded. Refer to Grounding, above. Follow the Pressure Relief
Procedure on page 2, and remove the spray tip/nozzle from the
gun/valve. Always use the lowest possible fluid pressure, and maintain
firm metal–to–metal contact between the gun/valve and the pail during
flushing to reduce the risk of fluid injection injury , static sparking and
splashing.

WARNING
Two accessories are required in your system: a
bleed–type master air valve (D) and a fluid drain
valve (H). These accessories help reduce the risk of
serious bodily injury including fluid injection, splash
ing in the eyes or on the skin, and injury from moving
parts if you are adjusting or repairing the pump.
See pages 16–18 for accessories available from Graco.
Be sure all accessories are properly sized to withstand
the pressures in the system.
-
The Typical Installation shown above is only a guide to
selecting and installing required and optional accesso-
ries. For assistance in designing a system to suit your
particular needs, contact your Graco representative.
The bleed–type master air valve relieves air trapped
between this valve and the pump after the air is shut
Trapped air can cause the pump to cycle unex-
pectedly. Locate the valve close to the pump.
off.
The Dimensional Drawing on page 19 provides neces-
sary measurements for mounting the pump. If you use an
accessory ram (J), as shown in the T ypical Installation,
refer to the separate ram manual for mounting dimension
requirements.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose and spray gun;
triggering the spray gun to relieve pressure may not
be sufficient.
System Accessories
Install the air line accessories in the order shown in the
Typical Installation. Working upstream from the pump air
inlet, install a pump runaway valve (F) to shut off the air to
the pump if the pump accelerates beyond the pread-
justed setting. A pump which runs too fast can be seri-
ously damaged.
Install a fluid drain valve (H) close to the pump fluid outlet.
Then connect a grounded fluid supply hose (L). Be-
tween the fluid supply hose (L) and the gun/dispensing
valve (K), install a whip hose (M) for greater flexibility

the pump air line to isolate the accessories for servicing.
GROUNDING
WARNING
Before operating the pump, ground the system as
explained under FIRE OR EXPLOSION HAZARD
and Grounding on page 3.
Be sure the pump air line (A) is properly grounded, and is
large enough to supply an adequate volume of air to the
motor. An air–powered ram (J) requires a separate
grounded air supply line (N).

To reduce the risk of fluid injection, DO NOT use
your hand or fingers to cover the bleeder hole when
priming the pump.
8. Leave the drain valve open until you are ready
to dispense again.
If you suspect that the spray tip/nozzle 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,
nozzle or hose end coupling and relieve pressure
gradually, then loosen completely. Now clear the
tip/nozzle or hose.
6. Release the trigger and engage the safety latch. 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 circulat

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 piston (located behind the air motor shield)
move. Therefore, NEVER operate the pump with
the air motor shield removed, and keep your fingers
and hands away from the priming piston.
WARNING
To reduce the risk of serious bodily injury, including
fluid injection and splashing in the eyes or on the
skin, and property damage, never exceed the maxi
mum air and fluid working pressure of the lowest
rated component in your system. See EQUIPMENT

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.
