Any misuse of the spray/dispensing equipment or accessories, such as

NEVER exceed the recommended working pressure or the maximum air

inlet pressure stated on your pump or in the TECHNICAL DATA on

pages 24-29.

overpressurizing, modifying parts, using incompatible chemicals and flu

ids, or using worn or damaged parts, can cause them to rupture and result

in fluid injection, splashing in the eyes or on the skin, or other serious bod

ily injury, or fire, explosion or property damage.

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

CHECK all spray/dispensing equipment regularly and repair or replace

worn or damaged parts immediately

BE SURE that all fluids and solvents used are chemically compatible with

the wetted parts shown in the TECHNICAL DATA on pages 24-29. Al

ner tube and cover of the hose. DO NOT expose Graco hoses to tem

peratures above 82_C (180_F) or below –40_C (–40_F).

ALL FLUID HOSES MUST HA VE 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/dispensing 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

TIGHTEN all fluid connections securely before each use. High pressure

fluid can dislodge a loose coupling or allow high pressure spray to be

emitted from the coupling.

plier or manufacturer for the maximum resistance limits. Use a resistance

meter in the appropriate range for your hose to check the resistance. If

NEVER use a damaged hose. Before each use, check the entire hose for

cuts, leaks, abrasion, bulging cover, or damage or movement of the hose

couplings. If any of these conditions exist, replace the hose immediately

the resistance exceeds the recommended limits, replace it immediately

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.

An ungrounded or poorly grounded hose can make your system hazard

ous. Also, read FIRE OR EXPLOSION HAZARD, below

FIRE OR EXPLOSION HAZARD

Static electricity is created by the high velocity 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/dispensed, dust particles and other flammable sub-

stances, whether you are spraying/dispensing indoors or outdoors, and

To maintain grounding continuity when flushing or relieving pres

sure, always hold a metal part of the spray gun/dispensing valve

firmly to the side of a grounded metal pail, then trigger the gun/valve.

To ground the pump:

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

the ACCESSORIES section to order a ground wire and clamp.

can cause a fire or explosion and serious bodily injury and property dam

age. Do not plug in or unplug any power supply cords in the spray/dis

pensing area when there is any chance of igniting fumes still in the air

If you experience any static sparking or even a slight shock while using

this equipment, STOP SPRA YING/DISPENSING IMMEDIATELY.

Check the entire system for proper grounding. Do not use the system

again until the problem has been identified and corrected.

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:

1. Pump: use a ground wire and clamp. See Fig 1.

2. Air hoses: use only grounded air hoses.

3. Fluid hoses: use only grounded fluid hoses.

4. Air compressor: follow manufacturer’s recommendations.

Fig

5. Spray gun or dispensing valve: grounding is obtained through con

nection to a properly grounded fluid hose and pump.

Flushing Safety

6. Fluid supply container: according to your local code.

7. Object being sprayed: according to your local code.

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 spray

gun/dispensing 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.

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

paper or cardboard, which interrupts the grounding continuity

IMPORTANT

United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards – particularly the Gen

eral Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

OPERATION/MAINTENANCE

WARNING

Pressure Relief Procedure

WARNING

Moving parts can pinch or amputate your fingers or

other body parts. When the pump is operating, the

priming piston (25) (located at the pump intake) and

the air motor piston (located behind the air motor

plates or shield) move. See Fig. 2. Therefore,

NEVER operate the pump with the air motor plates

or shield removed, and keep your fingers and hands

away from the priming piston.

fluid injection, splashing in the eyes or on the skin, or

injury from moving parts, always follow this proce-

dure whenever you shut off the pump, when check

ing or servicing any part of the spray/dispensing sys

tem, when installing, cleaning or changing spray

tips/nozzles, and whenever you stop spraying/dis-

pensing.

Before attempting to clear an obstruction from the

priming piston (25) or service the pump, follow the

3. Close the bleed-type master air valve (required in

your system).

4. Disengage the gun/valve safety latch.

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.

Cycle the pump slowly until all the air is pushed out and

the pump and hoses are fully primed. Release the spray

gun/dispensing valve trigger and engage the safety latch.

The pump should stall against pressure when the trigger

is released.

6. Engage the gun/valve safety latch.

If the pump fails to prime properly, open the bleeder valve

(35) slightly. Use the bleed hole (R), on the underside of

the valve, as a priming valve until the fluid appears at the

hole. See Fig 2. Close the bleeder valve.

7. Open the drain valve (required in your system)

and/or the pump bleeder valve, having a con-

tainer ready to catch the drainage.

8. Leave the drain valve open until you are ready to

spray/dispense again.

NOTE: When changing fluid containers with the hose

and gun already primed, open the bleeder valve

(35), to assist in priming the pump and venting air

before it enters the hose. Close the bleeder valve

when all air has been eliminated.

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

(E), which shuts off the air supply to the pump if the pump

accelerates beyond the pre-set speed, is available. See

the Typical Installation on page 4 and ACCESSORIES

on pages 22 and 23. 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 solvent. Be sure to eliminate all air from

the fluid system.

Starting and Adjusting the Pump

See the TYPICAL INSTALLATION on page 4. If you are

using a ram or wiper plate with the pump, refer to the sep

arate instructions for those components for set-up and

operation instructions.

Lower the pump into a fluid container . Be sure the air

regulator (H) and pump’s bleed-type master air valve (G)

are closed. Then open the bleed valve (G). Hold a metal

part of the spray gun/dispensing valve (N) firmly to the

side of a grounded metal pail and hold the trigger open.

Now slowly open the air regulator until the pump starts.
