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
93 C (200 F). 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 93 C (200 F). 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.
Grounding
Installation
4.
Spray gun/dispense valve: ground through connection to a properly grounded fluid hose and pump.
WARNING
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.
5.
Object being sprayed: follow your local code.
6.
Fluid supply container: follow your local code.
7.
All solvent pails used when flushing: follow 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 paper or cardboard, which interrupts the grounding continuity.
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.
8.
To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun/valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
System Accessories
W
Y
X
Z
WARNING
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.
0864
Fig. 1
2.
Air and fluid hoses: use only electrically conductive hoses with a maximum of 150 m (500 ft) combined hose length, to ensure grounding continuity.
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.
3.
Air compressor: follow the air compressor manufacturer’s recommendations.
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.
6 307-951
Operation
Flush the Pump 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.
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.
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).
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 spray/dispense again.
If you suspect that the spray tip/nozzle or hose is com pletely clogged, or that pressure has not been fully re lieved 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.
1.
Relieve the pressure.
2. Remove the spray tip/nozzle from the gun/valve.
3. Hold a metal part of the gun/valve firmly to the side of a grounded metal pail.
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).
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.
NOTE: The system must be up to operating temperature.
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.
119
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.
A
101
139
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.
8 307-951
Operation
Keep the wet-cup (101) one-half full with TSL. No adjustment is necessary to the packing nut due to the packing design.
Shutdown and Care of the Pump
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.)
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.
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.
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.

The Graco Warranty and Disclaimers
WARRANTY
Graco warrants all equipment listed in this manual which is manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear 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 parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not 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.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PUR-
POSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no 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.

FOR A PARTICULAR PURPOSE IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS, OR COMPONENTS
SOLD BUT NOT MANUFACTURED BY GRACO. These items sold, but not manufactured by Graco (such as electric motors, switches, hose, etc.) are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.
