Keep the spray/dispense area free of debris, including solvent, rags, and gasoline.
Electrically disconnect all equipment in the spray/dispense area.
Extinguish all open flames or pilot lights in the spray/dispense area.
Do not smoke in the spray/dispense area.
Do not turn on or off any light switch in the spray/dispense area while operating or if fumes are
present.
Do not operate a gasoline engine in the spray/dispense area.
HOT FLUID AND HOT SURFACE HAZARD
Bodily contact with hot fluid and hot surfaces can cause severe burns. Obtain medical assistance
immediately.
The WARM-MELT pump and associated equipment is designed to be heated to a maximum of
93C (200F). Any or all components may be heated to their maximum temperature. Take extreme
care to avoid touching any of them. If bodily contact is made with any component, severe burns
may result. Obtain medical assistance immediately.
Warm melt materials are typically formulated to a heavy, sticky, mastic-type composition which
must be pumped at elevated temperatures not to exceed 93C (200F). While pumping these materials at elevated temperatures, extreme care must be taken to avoid bodily contact with the
heated material. If bodily contact does occur, do not wipe the material, as this can spread the material and cause additional burns. Cool the burn area with water and obtain medical assistance
immediately.
Always wear protective eyewear, gloves, and clothing.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
Know the specific hazards of the fluid you are using.
Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.
Installation
Grounding
4. Spray gun/dispense valve: ground through connection to a properly grounded fluid hose and pump.
WARNING
5. Object being sprayed: follow your local code.
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 5.
1. Pump: use a ground wire and clamp. See Fig. 1.
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. Connect the other end of the
wire to a true earth ground.
Two accessories are required in your system: a
bleed-type master air valve and a fluid drain valve.
These accessories help reduce the risk of serious
injury, including 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.

6. Fluid supply container: follow your local code.
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. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
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:
are instructed to relieve the pressure,
stop spraying/dispensing,
check or service any of the system equipment,
or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Shut off the air supply to the pump.
3. Close the bleed-type master air valve (required in
your system).
Flush the Pump
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.
WARNING
FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page
5. Be sure the entire system and flushing pails are properly grounded. Refer to
Grounding on page 6.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
4. Unlock the gun/valve trigger safety.
1. Relieve the pressure.
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.
2. Remove the spray tip/nozzle from the gun/valve.
6. Lock the gun/valve trigger safety.
3. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail.
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
spray/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 or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
4. Start the pump. Always use the lowest possible
fluid pressure when flushing.
5. Trigger the gun/valve.
6. Flush the system until clear solvent flows from the
gun/valve.
7. Relieve the pressure.
Operation
Start and Adjust the Pump
Fill the packing nut (101) 1/2 full with Graco Throat
Seal Liquid (TSL).
101
Be sure the main pump air regulator is closed. Then
open the bleed-type master air valve. Hold a metal part
of the gun/valve firmly to the side of a grounded metal
pail and hold the trigger open. Now slowly open the air
regulator until the pump starts.
139
NOTE: The system must be up to operating temperature.
A
Cycle the pump slowly until all air is pushed out and
the pump and hoses are fully primed. Release the gun/
valve trigger and lock the trigger safety. The pump will
stall against pressure when the trigger is released.
WARNING
MOVING PARTS HAZARD
Keep hands and fingers away from the
priming piston (119) during operation
and whenever the pump is charged with
air. The priming piston extends beyond the intake
cylinder (117) to pull material into the pump and
can amputate a hand or finger caught between it
and the intake cylinder. Follow the Pressure Relief
Procedure on page 7, before checking, clearing,
or cleaning the priming piston.
If the pump fails to prime properly, open the bleeder
valve (139) slightly. Use the bleed hole (A) as a priming valve until the fluid appears at the hole. See Fig. 2.
Close the bleeder valve.
WARNING
INJECTION HAZARD
To reduce the risk of fluid injection, do not use
your hand or fingers to cover the bleed hole (A) on
the underside of the bleeder valve body (139) when
priming the pump.
8
307-951
119
7051A
Fig. 2
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as you open and close the gun/valve.
NOTE: All electrical and heat requirements must be
met.
Use the air regulator to control the pump speed and
the fluid pressure. Always use the lowest air pressure
necessary to get the desired results. Higher pressures
cause premature tip/nozzle and pump wear.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause component rupture and serious injury, never
exceed the Maximum Incoming Air Pressure to the
pump.
Operation
Keep the wet-cup (101) one-half full with TSL. No adjustment is necessary to the packing nut due to the
packing design.
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. A pump runaway
valve, which shuts off the air supply to the pump if the
pump accelerates beyond the preset speed, is available. (See your authorized Graco dealer.)
If your pump accelerates 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, refill the container and prime the pump
and the lines with fluid, or flush and leave it filled with a
compatible material.
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 7.
For overnight shutdown, stop the pump at the bottom
of the stroke to prevent fluid from drying on the exposed displacement rod and damaging the throat
packings. Relieve the pressure. Follow all heat
shutdown procedures.
Always flush the pump before the material sets up on
the displacement rod. First, flush with a compatible
material. Relieve the pressure, but leave the compatible flush material in the pump to protect the parts from
corrosion.
Service/Troubleshooting

Throat Packing Periodic Replacement
CAUTION
When pumping abrasive fluid, periodic replacement
of the throat packings, in addition to the regular
pump packing replacement, is essential. Abrasive
fluids cause the throat packings to wear more quickly, and costly damage to the displacement rod may
result from scoring.
Check the throat packings weekly until you determine how frequently you need to change the packings to reduce displacement rod scoring. Good
packings should not have any cracks, breaks, or
worn spots.
Order three packings (part no. 617–012) and three
packings (part no. 617–013). To change the throat
packings:
1. Unscrew the coupling nut (9). Remove the cotter
pin (1), loosen the jam nut (5), and unscrew the
connecting rod (11).

caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident,
tampering, or substitution 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, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor
for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective

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

other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two
(2) years of the date of sale.
