HOW THE ELECTROSTATIC (ES) AIR-ASSISTED AIRLESS SPRAY
This gun combines electrostatic air spray and airless
spraying concepts. The air has three functions: (1) to
drive the turbine, (2) to help atomize the paint "tails",
and (3) to help control the pattern sizs.
The spray tip shapes the fluid into a fan pattern, similar
to a conventional airless spray tip, but at a lower
pressure. Air from the air cap further atomizes the fluid
and pushes the paint tails into the pattern. The fan adjusting knob controls the width of the pattern.
The turbine generates power which the power cartridge
converts to a high voltage current. The high voltage
current charges the gun's ionizing electrode.
Fluid is electrostatically charged as it passes the gun's
ionizing electrode. The charged fluid is attracted to the
grounded work piece, wrapping around and evenly
coating all surfaces.

PERSONNEL WHO SHALL BE FULLY CONVERSANT WITH THE REQUIREMENTS STATED WITHIN THIS INSTRUCTION MANUAL.
FLUID INJECTION HAZARD
i~
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes can.cause serious
damage.
NEVER point the spray gun a t anyone or at any PSK of the
body. NEVER put hand or fingers over the spray tip. NEVER
try to ”blow back“ paint; this is NOT an air spray system.
ALWAYS follow the Pressure Relief Procedure. a t right,
before cleaning or removing the spray tip mor servicing any
system equipment.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment safety devices are operating properly
before each use.
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly before
each use. Do not remove or modify any part of the gun; thls
can cause a malfunction and result in serious bodily injury.
Safely Latch
Whenever you stop spraying, even for a moment. always set
the gun safety latch in the closed or “locked“ position, making
the gun inoperative by depressing the safety latch on the left
or right of trigger. See the illustration below. Failure to set the
safety latch can result in accidental triggering of the gun.

DO NOT TREAT AS A SIMPLE CUT.
Tell the doctor exactly what fluid was injected. For treatment
instructions, have your doctor call the
NATIONAL POISON CENTER NETWORK
(412)681-6669
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including injection
or injury from moving parts or electric shock, always follow
this procedure when shutting off the system, when checking
or servicing any part of the spray system. when installing,
cleaning or changing spray tips, and whenever you stop spraymg.
1. Engage the gun safety latch.
2. Turn the ES ON-OFF valve lever t o OFF.
3. Turn off air and fluid supply t o the gun.
4. Disengage the gun safety latch.
5. Trigger the gun into a grounded metal waste container to
relieve fluid pressure.
6. Engage the gun safety latch.
7. Open the pump drain valve, having a grounded metal waste
container ready to catch the drainage.
8. Leave the pump drain valve open until you are ready to
spray again.
If you suspect that the tip or hose is~completelyclogged, or
that pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen the air cap retainer or
hose end coupling and relieve pressure gradually, then loosen
completely. Now clear the tip or hose.
EOUlPMEAlT MISUSE HAZARDE
Diffuser
The gun diffuser breaks up spray and reduces the risk of injection when the spray tip is not installed. To check diffuser
operation, follow the Pressure Relief Procedure. at right,
and then remove the spray tip. Aim the gun into a gtounded
metal pail. With the ES ON-OFFvalve leverturned t o OFF, and
uslng the lowest possible pressure, trigger the gun. If the fluid
emitted is not diffused into an irregular stream, replace the diffuser immediately.
Spray Tip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, engage the gun safety latch
immediately. ALWAYS follow the Pressure Relief Procedure and then remove the spray tip to clean it.
NEVER wipe off build-up around the spray tip until pressure is
fully relieved and the gun safety latch is engaged.

General Safety
Any misuse of the spray equipment or accessories. such as
overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in injection or other serious
bodily injury, fire, explosion or propew damage.
NEVER alter or modify any part of this equipment; doing so
could cause it t o malfunction.
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
This gun has a maximum working pressure of 66 bar
1950 psi). Never exceed the maximum working pressure of the
gun or any other component or accessory used in the system.
FIRE OR EXPLOSlON HAZARD
All parts of the electrostatic spray system must be properly
grounded to reduce the risk of static electricity discharge.
Static electricity is created by the high velocity flow of fluid
through the pump and hose and the spray gun‘s internal
power supply. Ungrounded objects can become electrically
charged and sparking may occur. Sparks can ignite fumes
from solvents, fluid being sprayed, dust particles and other
flammable substances, which can cause a fire or explosion
and result in serious bodily injury and property damage.
If you experience any sparking or feel even a slight shock,
STOP SPRAYING IMMEDIATELY. Check for proper grounding of the entire system. Be sure you have corrected the problem before starting t o spray again.
Groundlng
Following are the minimum requirements for grounding a
basic electrostatic system. Your system may include other
equipment or objects which must also be grounded. Always
check your local electrical code for detailed grounding instructions. Be sure your system is connected to a true earth
ground.
1. Pump: ground by using a ground wire &d clamp as
described in your separate pump instruction manual.
2. Air compressors and hydraulic power supplies: ground
according t o the manufacturer‘s recommendations.
3. Pro AA4ow gun: obtain grounding through connection t o
a properly grounded air supply hose. Use only the GRACO
ELECTRICALLY CONDUCTIVE AIR SUPPLY HOSE; see
page 20 t o order. Connect the air hose ground wire to a
true earth ground.
4. Object being sprayed: keep work piece hangers clean and
grounded at all times. Contact points must be sharp points
or knife edges.
5. A l l electricallv conductive objects in the spray area must be
properly grounded.
6. Allpersons entering the spray area: shoes must have conductive soles, such as leather, or personal grounding.~straps
.~
.
must be worn. Rubber or plastic soles are not conductive.
The operator must not wear gloves which Insulatethe hand
from the spray gun. See page 5 for how t o modify the
glove.
The floor of the spray area must be electrically conductive
and grounded. 00 not cover the floor with cardboard or
any non-conductive material which would interrupt
grounding continuity.
8. Flammableliquidsin thesprayarea must be kept in approved, grounded containers. Do not store more than the quantity needed for one shift.
9. A l l solvent pails: use only grounded metal pails, which are
conductive. Do not place the pail on any non-conductive
surface, such as cardboard or paper, which would interrupt
grounding continuity.
Flushing and Cleaning Safety
To reduce the risk of an injection injury, static sparking, or
splashing, always follow the Pressure Relief Procedure on
page 2 and remove the spray tip before flushing. Use lowest
possible pressure and use a grounded metal waste container.
Be sure the
ES valve lever is OFF during flushing.
N N E R use solvents having a flash point of less than 2 1 T
(70°F) t o clean the gun. NEVER use solvents having a flash
point of less than 38OC (1OOOF) t o clean the spray system.
ALWAYS remove a11 solvent from the system before reactivating the spray gun.
Use only non-sparking tools to clean residue from the booth
and hangem.
Ventilate t h e Spray Booth
To prevent hazardous concentrations of toxic and/or flamrnable vapors, spray only in a properly ventilated spray booth.
N N E R operate the spray gun unless the ventilating fans are
operating.
HOSE SAFETY
Highly pressurized fluid contained in the hose can be very
dangerous. Ifthe hose develops a leak, split or rupture due to
any kind of wear, damage or misuse, the high pressure spray
emitted from it can cause an injection injury or other serious
bodily injury or property damage.
TIGHTEN all fluid connections securely before each use. High
Pressure fluid can dislodge a loose coupling or allow high
pressure spray t o be emitted from the coupling.
NEVER use a damaged hose. Before each use, check 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. DO NOT try to recouple
high pressure hose or mend it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT expose the hose to temperataures above 82%
IlBOOF) or below -40°C I-40°FI.
United States Government safety standards have been adopted under the Occupational Safety and Health Act. Thesestandards-particularly the General Standards, Part 1910.107 and any other appropriate regulations-should be consulted in connection with the installation, operation and maintenance of electrostatic spray painting equipment.

and sediment which could clog the spray tip. See Fig 6.
Install the Spray Tip b Adjust the Spray Pattern
1. Select the appropriate spray tip for your application
from the Spray Tip Selection Chart on page 21. The
fluid output and fan width depend on the size of the
spray tip, the fluid viscosity, and the fluid pressure.
2.
Place the tip (13) in the air cap (12),aligning the tab
of the tip with the groove in the air cap. Be careful
not to damage the electrode wire (GG). Place the
air cap assembly on the gun and screw on the retaining ring (11) firmly. The air cap and spray tip
position determines the direction of the spray paltern. See Fig 3.
3. Adjust the fluid pressure. Turn on the fluid to about
21 bar (300 psi). Trigger the gun to check the
atomization; don't be concerned about the pattsrn shape yat. Increase the fluid pressure just to
the point that any further increase in fluid pressure
does not significantly improve fluid atomization.
DO NOT exceed 66 bar 1950 psi1 fluid pressure.

use a different size tip.
i
Spraying Operation
This gun has a built-in lead and lag operation. The gun
begins emitting air before the fluid is discharged. When
you release the trigger, the fluid stops before the air
flow stops. This helps prevent fluid buildup on the air
cap.
