WARNINGS
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating the equipment.
FLUID INJECTION HAZARD
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 or on the skin can cause serious damage.
NEVER point the spray gun at any one or at any part of the body .
NEVER
put your hand or fingers over the spray tip. NEVER try
to “blow back” paint; this is NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYS
follow the PRESSURE RELIEF PROCEDURE , below ,
before cleaning or removing the spray tip or 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.
Medical Alert––Airless Spray W ounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE
CUT.
T ell the doctor exactly what fluid was injected.
Note to Physician : Injection into the skin is a traumatic injury .
It is important to treat the injury surgically as soon as possible.
Do not delay treatment to research toxicity. Toxicity is a
concern with some exotic coatings injected directly into the
blood stream. Consultation with a plastic surgeon or re-
constructive
hand surgeon may be advisable .
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; this can
cause a malfunction and result in serious bodily injury .
Safety Latch
Whenever you stop spraying, even for a moment, always set the
gun safety latch in the closed or “safe” position, making the gun
inoperative. Failure to set the safety latch can result in accidental
triggering of the gun.
Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid
injection
when the tip is not installed. Check the dif fuser opera -
tion
regularly . Follow the PRESSURE RELIEF PROCEDURE ,
below,
then remove the spray tip. Aim the gun into a metal pail,
holding the gun firmly to the pail. Using the lowest possible pres -
sure,
trigger the gun. If the fluid emitted is not dif fused into an ir -
regular
stream, replace the dif fuser immediately .
Tip Guard
ALWAYS have the tip guard in place on the spray gun while
spraying.
The tip guard alerts you to the fluid injection hazard and
helps reduce, but does not prevent, the risk of accidentally plac -
ing
your fingers or any part of your body close to the spray tip.
Trigger Guard
Always have the trigger guard in place on the gun when spraying
to reduce the risk of accidentally triggering the gun if it is dropped
or bumped.
Spray T ip Safety
Use extreme caution when cleaning or changing spray tips. If
the
spray tip clogs while spraying, engage the gun safety latch
immediately. AL WAYS follow the PRESSURE RELIEF PROCE -
DURE,
below, and then remove the spray tip to clean it.
NEVER wipe of f build–up around the spray tip until the pressure
is fully relieved and the gun safety latch is engaged.
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious bodily injury , including fluid injection,
splashing fluid or solvent in the eyes or on the skin, or injury from
moving parts or electric shock, always follow this procedure
whenever
you shut of f the sprayer , when checking or servicing
any part of the spray system, when installing, cleaning or chang -
ing
spray tips, and whenever you stop spraying.
1. Engage the gun safety latch.
2. Shut off the power to the pump and close any bleed-type
master air valves.
3.
Disengage the gun safety latch.
4. Hold a metal part of the gun firmly to the side of a grounded
metal pail, and trigger the gun to relieve pressure.
5. Engage the gun safety latch.
6. Open the pressure drain valve, having a container ready to
catch the drainage. Leave the valve open until you are ready
to spray again.
If you suspect that the spray tip or hose is completely clogged,
or that pressure has not been fully relieved after following the
steps
above, VER Y SLOWL Y loosen the tip guard retaining nut
or hose end coupling to relieve pressure gradually , then loosen
completely. Now clear the tip or hose.

MOVING P ARTS HAZARD
Moving parts can pinch or amputate your fingers or other body
parts. KEEP CLEAR of moving parts when starting or operating
the sprayer . Follow the Pressure Relief Procedure on page 2
before checking or servicing any part of the sprayer , to prevent
it from starting accidentally .
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible chemi-
cals and fluids, 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 bodily injury, or fire, explosion or
property
damage.
NEVER alter or modify any part of this equipment; doing so could
cause it to malfunction.
CHECK all spray equipment regularly and repair or replace worn
or damaged parts immediately .
Always
wear protective eyewear , gloves, clothing and respirator
as recommended by the fluid and solvent manufacturer .
System Pressure
The gun has a 5000 psi (345 bar) MAXIMUM WORKING PRES -
SURE.
The RAC IV T ip Guard has a 4050 psi (279 bar) MAXI -
MUM
WORKING PRESSURE. DO NOT exceed the maximum
working pressure of the supply pump or the lowest-rated compo -
nent
in the system.
Fluid and Solvent Compatibility
All chemicals used in the gun must be chemically compatible
with
the wetted parts shown in the TECHNICAL DA TA on page
12. Consult your chemical supplier to ensure compatibility .
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
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 a fluid injection injury or other serious bodily injury or prop -
erty
damage.
ALL FLUID HOSES MUST HA VE STRAIN RELIEFS ON BOTH
ENDS! The strain reliefs help protect the hose from kinks or
bends
at or close to the coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high pres -
sure
spray to be emitted from the coupling.
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 . DO NOT try to recouple high pres -
sure
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. Keep hoses clear of moving parts and
hot surfaces of the pump. Do not use fluids or solvents which are
not compatible with the inner tube and cover of the hose. DO
NOT
expose Graco hoses to temperatures above 180  F (82 
C) or below –40  F (–40 C).
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a
grounded spray system. Check the electrical resistance of your
fluid hoses at least once a week. If your hose does not have a
tag on it which specifies the maximum electrical resistance, con -
tact
the hose supplier or manufacturer for the maximum resis -
tance
limits. Use a resistance meter in the appropriate range for
your hose to check the resistance. If the resistance exceeds the
recommended limits, replace it immediately . An ungrounded or
poorly grounded hose can make your system hazardous. Also
read FIRE OR EXPLOSION HAZARD, below.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump
and hose. If every part of the spray equipment is not properly
grounded, sparking may occur, and the system may become
hazardous. Sparking may also occur when plugging in or un-
plugging
a power supply cord or using a gasoline engine. Sparks
can ignite fumes from solvents and the fluid being sprayed, dust
particles and other flammable substances, whether you are
spraying
indoors or outdoors, and can cause a fire or explosion
and serious bodily injury and property damage. Always plug an
electric-powered sprayer into an outlet at least 20 feet (6 m) away
from the sprayer and the spray area. Do not plug in or unplug
any power supply cords in the spray 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, ST OP SPRA YING IMMEDIA TELY . 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 sprayer and all
other spray equipment used or located in the spray 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 equipment:
1. Sprayer or pump: as instructed in your separate sprayer or
pump
manual.
2. Air and fluid hoses: use only grounded hoses. See Hose
Grounding
Continuity on page 3.
3. Spray gun: obtain grounding through connection to a prop-
erly
grounded fluid hose and sprayer .
4.
Object being sprayed: according to local code.
5. Fluid supply container: according to local code.
6. All solvent pails used when flushing, according to local code.
Use only metal pails, which are conductive. Do not place the
pail on a non–conductive surface, such as paper or card-
board,
which interrupts the grounding continuity .
7.
To maintain grounding continuity when flushing or relieving
pressure
, always hold a metal part of the gun firmly to the side
of a grounded metal pail, then trigger the gun.
Flushing Safety
Reduce the risk of fluid injection injury , static sparking, or splash -
ing by following the flushing procedure given in your separate
sprayer
or pump manual. Follow the PRESSURE RELIEF PRO -
CEDURE
on page 2, and remove the spray tip before flushing.
Hold a metal part of the gun firmly to the side of a grounded metal
pail and use the lowest possible fluid pressure during flushing.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards –
particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

4307–633
INSTALLATION
NOTE: Numbers and letters in parentheses in the text
correspond
to the reference numbers and letters
in the drawings and parts list.
Be sure your system has a bleed-type master air
valve (pneumatic pumps only) and a fluid drain
valve.
These two accessories help reduce the risk
of serious bodily injury, including fluid injection,
splashing
in the eyes or on the skin, or injury from
moving parts, if you are adjusting or repairing the
pump
or gun.
1. The bleed-type master air valve relieves air
trapped
between this valve and the pump after
the air regulator is shut off. Trapped air can
cause
the pump to cycle unexpectedly .
2. 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 suf ficient.
WARNING
1. Guide a grounded fluid hose (A) through the hose
guard (8), and connect the hose to the gun inlet
adapter (13).
2. With
no tip installed, start the pump or sprayer . Flush
it according to the instructions supplied with it.
3. Strain the fluid you are spraying if it has particles that
could clog the spray tip. Prime the system with the
fluid
you are spraying.
4. Relieve pressure. See the procedure on page 2.
5. Be sure the gun safety latch is engaged. See Fig 2.
Then install the tip and tip guard.
If you are using a Reverse-A-CleanIV DripLess
Tip Guard and SwitchTip, refer to manual
307–848,
supplied, for detailed instructions.
If you are using a flat tip and tip guard , place the tip
and then the gasket (17) in the tip guard (16) and
screw
the assembly tightly onto the gun nozzle.

To reduce the risk of serious bodily injury , including
fluid injection or splashing in the eyes or on the
skin, always follow the Pressure Relief Proce-
dure
on page 2 before checking, servicing, remov -
ing, changing or cleaning spray tips or any part of
the
gun or system.
Whenever you stop spraying for a moment, en-
gage
the gun safety latch. See Fig 2.
WARNING
WARNING
The wallet-sized warning card provided with this
gun should be kept with the operator at all times.
The
card contains important treatment information
should an injection injury occur. Additional cards
are
available from Graco Inc. at no charge.
1. Start the pump. Adjust the fluid pressure so the spray
is completely atomized. Always use the lowest pres -
sure necessary to get the desired results. Higher
pressure
may not improve the spray pattern and will
cause premature tip and pump wear .
2. If
adjusting the pressure does not give a good spray
pattern, try another tip size. Relieve pressure com-
pletely
before changing tips.
3. For maximum seat and needle life, Use a full-open,
full-close trigger action. Hold the gun about 14 in.
(350 mm) from and at right angles to the work sur-
face. Don’t swing the gun in an arc. Practice to find
the
best length and speed of stroke.
Adjust the spray pattern
1. To adjust the spray pattern direction, first relieve
pressure.
Be sure the trigger safety latch is engaged.
Loosen the tip guard retaining nut. T urn the tip guard
so it is vertical for vertical pattern and horizontal for
a horizontal pattern. Tighten the retaining nut. See
Fig
3.
2. The spray tip orifice size and spray angle determines
the coverage and size of pattern. When more cover -
age
is needed, use a larger spray tip rather than in -
creasing the fluid pressure.
WARNING
To
reduce the risk of a fluid injection injury , NEVER
use the gun with the tip guard or trigger safety
removed.
Openings in the tip guard are designed to reduce
paint buildup on the guard when spraying. Any
damage
to the sharp edges of the openings causes
paint to collect at that area. To reduce the risk of
damage,
never hang the gun by the tip guard. See
Fig 3.

OPERATION
Cleaning and clearing the spray tip
To
reduce the risk of a fluid injection or splashing in
the eyes or on the skin, DO NOT hold your hand,
body,
or a rag in front of the spray tip when cleaning
or checking a clogged tip. Always point the gun to -
ward the ground or into a waste container when
checking
to see if the spray tip is cleared.
DO NOT try to “blow back” paint; this is NOT an air
spray gun.
DO NOT wipe fluid buildup of f the gun or spray tip
until pressure is relieved. See the Pressure Relief
Procedure on page 2.
WARNING
1. Clean off the front of the tip frequently during the
day’s operation and at the end of each work day . Re -
lieve
pressure first. Then use a solvent-soaked brush
to clean the spray tip and to keep fluid buildup from
drying
on and clogging the spray tip.
2. If the spray tip clogs while spraying, release gun trig -
ger
and engage the trigger safety latch.
If you are using a Reverse-A-CleanrIV DripLesst
Tip Guard and SwitchTipt, rotate the SwitchTip
180_.
Disengage the trigger safety latch. T rigger the
gun into a waste container . This should force the ob -
struction
from the tip. Engage the trigger safety latch
and return the SwitchT ip to the normal spraying posi -
tion.
If you are using a flat tip and tip guard, shut off the
power to the pump or sprayer. Open the pressure
drain valve. Without holding your hand over the tip,
very
slowly loosen the tip guard retaining nut and re -
lieve pressure gradually. Remove the tip guard and
tip.
Soak the tip in a compatible solvent, and then tap -
ping
the back of the tip on a flat surface to remove the
clog. Do not use sharp instruments which can dam -
age the tip. Reinstall the tip and tip guard.
CAUTION
NEVER soak the entire gun in solvent. Prolonged
exposure
to solvent can ruin the packings.
Flush the gun
To
reduce the risk of static sparking and splashing,
be sure the entire system and the flushing pails are
properly grounded. See Grounding on page 3.
Use
low fluid pressure and maintain metal-to-metal
contact between the gun a the grounded pail. See
Fig 4.
WARNING
1.
Relieve pressure. See the procedure on page 2.
2. Remove the spray tip.
3. Flush the gun and system with a solvent compatible
with the material you are spraying and the wetted
parts
of the system.

Adjusting the needle See Fig 6.
WARNING
Proper
adjustment of the needle is essential to be
sure the trigger safety latch makes the gun inop-
erative when engaged. Improper adjustment may
allow
the gun to be triggered, even with the trigger
safety latch engaged, resulting in serious bodily in -
jury, including fluid injection and splashing in the
eyes
or on the skin.
1. Hold the gun with the nozzle straight up so the trigger
falls onto the safety latch. Insert a flat blade screw-
driver
into the rear port of the gun until it engages with
the slot (C) at the back of the needle.
NOTE: If the trigger does not touch the latch, turn the
needle
clockwise until it does.
2. With light pressure, hold the trigger against the latch.
Turn the needle counterclockwise until there is
enough tension for you to feel and see the trigger
raise
slightly of f the latch.
3. Now turn the needle back (clockwise) 3/4 turn.
4. Install the plug (3).
5. To test the adjustment: Connect the fluid hose and
start
the pump. Release the trigger safety latch and
trigger the gun into a grounded waste container .
Release the trigger – the fluid should stop flow-
ing immediately .
Engage the safety latch again and try to trigger
the
gun – no fluid should flow .
