WARNINGWARNINGWARNING
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.

Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable
vapors. To help prevent fire and explosion:
• Clean plastic parts only in a well ventilated area.
• Do not clean with a dry cloth.
• Do not operate electrostatic guns in equipment work area.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just
a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or ser-
vicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-
ponent. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about
your material, request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment
and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufac-
turer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure and disconnect all power sources.
SUCTION HAZARD
Powerful suction could cause serious injury.
• Never place hands near the pump fluid inlet when pump is operating or pressurized.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swal-
lowed.
• Read MSDSs to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
• Always wear chemically impermeable gloves when spraying, dispensing, or cleaning equipment.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating area
of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of
toxic fumes, and burns. This equipment includes but is not limited to:

Important Two-Component Material Information
6312799H
Important Two-Component Material Information
Isocyanate Conditions
Material Self-ignition
Keep Components A and B
Separate
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
coatings. ISO will react with moisture (such as humidity)
to form small, hard, abrasive crystals, which become
suspended in the fluid. Eventually a film will form on the
surface and the ISO will begin to gel, increasing in vis-
cosity. If used, this partially cured ISO will reduce perfor-
mance and the life of all wetted parts.
NOTE: The amount of film formation and rate of crystal-
lization varies depending on the blend of ISO, the
humidity, and the temperature.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Never use solvent on one side if it has been contam-
inated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
• When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after flushing.
• Check with your material manufacturer for chemical
compatibility.
• Most materials use ISO on the A side, but some use
ISO on the B side.
Spraying or dispensing materials containing isocya-
nates creates potentially harmful mists, vapors, and
atomized particulates.
Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventila-
tion in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or dam-
age equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (isocyanate) and component B (resin)
parts.

Prepare the Site
Ensure that you have an adequate compressed air
supply.
Bring a compressed air supply line from the air com-
pressor to the pump location. Be sure all air hoses are
properly sized and pressure-rated for your system. Use
only electrically conductive hoses. The air hose should
have a 3/8 npt(m) thread. A quick disconnect coupling is
recommended.
Keep the site clear of any obstacles or debris that could
interfere with the operator's movement.

Mount the Pump
Mount the pump directly to the wall (order Wall Mounting
Kit, page 37) or to a Graco cart (order Cart Mounting Kit
24E879).
Wall-Mounted Pumps
1. Be sure the wall can support the weight of the
pump, bracket, hoses and accessories, as well as
the stress caused during operation.
2. Position the wall bracket about 1.2-1.5 m (4-5 ft)
above the floor. For ease of operation and service,
make sure the pump air inlet, fluid inlet, and fluid
outlet ports are easily accessible.
3. Using the wall bracket as a template, drill 10 mm
(0.4 in.) mounting holes in the wall. Wall mounting
dimensions are shown on page 43.
4. Attach the bracket to the wall. Use 9 mm (3/8 in.)
screws that are long enough to keep the pump from
vibrating during operation.
NOTE: Be sure the pump is level.
Cart-Mounted Pumps
Kit 24E885 is available if you plan to bolt your cart to the
floor. It includes two spacers that keep the legs stable.
Bolts not included.
Supplied Components
See FIG. 1 and FIG. 2. Components vary by package
ordered. See tables on pages 8 to 13. Your package
may include:
• The red-handled bleed-type master air valve (E) is
required in your system to relieve air trapped
between it and the air motor and gun when the valve
is closed. Do not block access to the valve.
Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.
•Thepump air regulator (H) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
•Theair relief valve (not shown) opens automati-
cally to prevent overpressurization of the pump.
•Thegun air regulator (D) adjusts the air pressure
to the air-assisted spray gun (L).
•Theair-assisted or airless spray gun (L) dis-
penses the fluid. The gun houses the spray tip (not
shown), which is available in a wide range of sizes
for different spray patterns and rates of flow. Refer to
gun manual for tip installation.
• The transparent hose (N, labeled “Air Hose Only”)
provides the gun air supply.
• The blue hose (M) provides the gun fluid supply.
•Thegun swivel (K) allows for freer gun movement
and comes attached to the blue hose.
•Thesuction hose (U) allows the pump to draw fluid
from a 5 gallon (19 liter) pail. A strainer also is sup-
plied. If using non-Graco supplied suction hose, see
inlet pressure notice, page 19.
•Afluid filter (P) with a 60 mesh (250 micron) stain-
less steel element filters particles from fluid as it
leaves the pump.
•Afluid drain valve (V) relieves fluid pressure in the
hose and gun.
•DataTrak (F) provides pump diagnostics and mate-
rial usage information. See page 22.
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.

Installation
312799H 17
Air Line Accessories
Install the following accessories in the order shown in
FIG. 1 and FIG. 2, using adapters as necessary.
•Anair-line filter (B) removes harmful dirt and mois-
ture from the compressed air supply.
•Asecond bleed-type air shutoff valve (A) isolates
the air line accessories for servicing. Locate
upstream from all other air line accessories.
Grounding
Pump: See FIG. 3. Verify that the ground screw (GS) is
attached and tightened securely to the air motor. Con-
nect the other end of the ground wire (S) to a true earth
ground.
Air and fluid hoses: Static electricity may build up
when fluids flow through pumps, hoses, and sprayers. At
least one hose must be electrically conductive, with a
maximum of 500 ft. (150 m) combined hose length to
ensure grounding continuity. Check electrical resistance
of hose. If total resistance to ground exceeds 25 meg-
ohms, replace hose immediately.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun / Dispense valve: Ground the spray gun
through connection to a Graco-approved grounded fluid
hose.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Setup
1. See FIG. 2. Attach end of blue fluid hose (M) without
gun swivel (K) to pump outlet (R) or filter (P) outlet.
2. Attach one end of the air hose (N) to gun air
regulator (D).
3. Attach remaining end of the air hose (N) to air inlet
at base of gun (L).
4. Attach other end of blue fluid hose (M), with gun
swivel (K), to gun fluid inlet.
5. Clip fluid and air hoses together with the supplied
hose clips (qty. of 7). Space clips as needed.
6. Apply lens cover to both regulator gauge lenses.
Order Kit 24A540 for 5 sheets of 12 lens covers.
7. Verify that suction hose fittings are tight.
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by provid-
ing an escape wire for the electrical current due to
static build up or in the event of a short circuit.

Operation
Pressure Relief Procedure
1. Lock the gun trigger.
2. See FIG. 2. Turn off the bleed-type master air valve
(E).
3. Unlock the gun trigger.
4. Hold a metal part of the gun firmly to a grounded
metal waste container. Trigger the gun to relieve
fluid pressure.
5. Lock the gun trigger.
6. Open all fluid drain valves in the system, having a
waste container ready to catch the drainage. Leave
the drain valve(s) open until you are ready to spray
again.
7. If you suspect that pressure has not been fully
relieved after following the steps above, check the
following:
a. The spray tip may be completely clogged. Very
slowly loosen the air cap retaining ring to relieve
pressure in the cavity between the ball/seat
shutoff and the plugged tip. Clear the tip orifice.
b. The gun fluid filter or the fluid hose may be com-
pletely clogged. Very slowly loosen the hose
end coupling at the gun and relieve pressure
gradually. Then loosen completely to clear the
obstruction.
c. After following the steps above, if the spray tip
or hose still seems completely clogged, very
slowly loosen the tip guard retaining nut or hose
end coupling and relieve pressure gradually,
then loosen completely. With tip removed, trig-
ger gun into waste container.
Flush the Pump Before First Use
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. See Flushing, page 21.
Trigger Lock
See FIG. 4. Always lock the gun trigger when you stop
spraying to prevent gun from being triggered acciden-
tally by hand or if dropped or bumped.
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.

Prime and Adjust the Pump
1. Lock the gun trigger. Remove tip guard and spray tip
from gun. Refer to gun manual.
2. Close gun air regulator (D) and pump air regulator
(H) by turning knobs counterclockwise reducing
pressure to zero. Close bleed-type air valve (E).
Also verify that all drain valves are closed.
3. Check that all fittings throughout system are tight-
ened securely.
4. Position pail close to pump. Do not stretch suction
hose tight; let it hang to assist fluid flow into pump.
5. Hold metal part of gun (L) firmly to side of grounded
metal pail, unlock trigger, and hold trigger open.
6. Pumps with runaway protection: Enable the
prime/flush function by pushing the prime/flush but-
ton on the DataTrak.
7. Open bleed-type air valve (E). Slowly open the
pump air regulator (H) until the pump starts.
8. Cycle pump slowly until all air is pushed out and the
pump and hoses are fully primed.
9. Pumps with runaway protection: Disable the
prime/flush function by pushing the prime/flush but-
ton on the DataTrak.
10. Release the gun trigger and engage the trigger lock.
Pump should stall against pressure.
11. In a direct supply system, with the pump and lines
primed, and with adequate air pressure and volume
supplied, the pump will start and stop as the
gun/valve is opened and closed.
12. In a circulating system, the pump runs continuously
and speeds up or slows down as the system
demands until the air supply is shut off.
13. Use the air regulator to control the pump speed and
the fluid pressure. Always use the lowest air pres-
sure necessary to get the desired results. Higher
pressures cause premature tip/nozzle and pump
wear.
Install the Spray Tip
Follow Pressure Relief Procedure, page 18. Install the
spray tip and tip guard as explained in your separate
gun manual, supplied.
The fluid output and pattern width depend on the size of
the spray tip, the fluid viscosity, and the fluid pressure.
Use the Spray Tip Selection Chart in your gun instruc-
tion manual as a guide for selecting an appropriate
spray tip for your application.
NOTICE
TO PREVENT A BELLOWS FAILURE:
• Do not exceed fluid inlet pressure of 15 psi
(0.1 MPa, 1.0 bar).
• Do not use a ball check pump on the inlet side of
this pump.
• Do not use a suction tube with a check valve on
the inlet side of this pump.

NOTICE
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed, possibly damaging itself. If your pump accel-
erates quickly, or is running too fast, stop it immedi-
ately 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.

Operation
20 312799H
Adjust the Spray Pattern
1. Do not turn on atomizing air supply. Fluid pressure
is controlled by the air pressure supplied to the
pump (pump air regulator). Set fluid pressure at low
starting pressure. For low viscosity fluids (less than
25 sec, #2 Zahn cup) with lower percent solids (typi-
cally less than 40%), start at 300 psi (2.1 MPa, 21
bar) at pump outlet. For fluids with higher viscosity
or higher solids content, start at 600 psi (4.2 MPa,
42 bar). Refer to the following example.
Example:
2. Trigger gun to check atomization; do not be con-
cerned about pattern shape.
3. Hold gun perpendicular and approximately 12
inches (304 mm) from surface.
4. Move gun first, then pull gun trigger to spray onto
test paper.
5. Increase fluid pressure in 100 psi (0.7 MPa, 7 bar)
increments, just to the point where a further
increase in fluid pressure does not significantly
improve fluid atomization. Refer to the following
example.
Example:
6. See FIG. 6. Close off pattern adjustment air by turn-
ing knob (W) clockwise (in) all the way. This sets
gun for its widest pattern.
7. See FIG. 7. Set atomizing air pressure at about 5 psi
(0.35 bar, 35 kPa) when triggered. Check spray pat-
tern, then slowly increase air pressure until tails are
completely atomized and pulled into spray pattern.
Do not exceed 100 psi (0.7 MPa, 7 bar) air pressure
to gun.
See FIG. 6. For narrower pattern, turn pattern
adjustment valve knob (W) counterclockwise (out). If
pattern is still not narrow enough, increase air pres-
sure to gun slightly or use different size tip.
