Introduction
Pressure Control
The
pressure control includes an ON/OFF switch for
the sprayer
, the pressure–adjusting control knob, a
pressure–sensing device and a current–overload cir
-
cuit breaker with a manual–reset button. The pressure
control regulates the motor speed.
Motor
The DC motor has sealed bearings and replaceable
motor brushes. The motor operates whenever there is
a demand for fluid or additional fluid pressure. When
the pump is cycling, the motor sounds like the cranking
of an automobile starter
. When the pump is not cy
-
cling, the motor hums intermittently until the fluid pres
-
sure stabilizes, then the motor will shuts of
f. However
,
there is still power to the sprayer and the sprayer stays
pressurized and ready to use until you manually shut it
of
f and relieve the pressure.
The direct–current (DC) motor is less sensitive to low
voltage or voltage fluctuations than an alternating–cur
-
rent (AC) motor
. However
, long extension cords may
af
fect the sprayer performance.
Drive Assembly
The
drive assembly, which is sealed, transfers power
from the DC motor to the displacement pump.
Displacement Pump
The
displacement pump provides equal fluid delivery
on both the up and the down pump stroke strokes. The
pump has a packing nut which, when filled with Graco
Throat Seal Liquid T(SL), helps prevent damage to the
throat packings and piston rod.
Fluid Filter
The
fluid filter strains the paint to help avoid clogs in
the hose and the spray tip. The filter includes a reus
-
able element and has a pressure drain valve for manu
-
ally relieving fluid pressure.
Hoses
The grounded, nylon spray hoses have spring guards
on both ends. The 50 foot (15.2 meter) hose has a 1/4
inch ID. The 3 foot (0.9 meter), 3/16 inch ID hose pro
-
vides more flexible gun movement. The nylon hose
material acts as a pulsation dampener to absorb pres
-
sure fluctuations.
Spray Gun & RAC IV DripLess Tip Guard
The
spray gun has a trigger safety which prevents ac
-
cidental triggering when it is locked. The gun has a
filter for final paint–straining. The Reverse-A-Clean IV
(RAC IV) SwitchT
ip uses high pressure fluid to remove
clogs from the spray tip without removing it from the
gun. The RAC IV DripLess tip guard is a safety feature
which helps reduce the risk of a skin injection injury
.

WARNINGS
High Pressure Spray Can Cause Serious Injury
. For Professional Use Only.
Observe All W
arnings. Read and understand all instruction manuals before operating 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 bod
-
ily
injury
, including the need
for amputation. Also, fluid injected
or
splashed into the eyes or
on the skin can cause serious dam
-
age.
Never
point the spray gun at anyone or at any part 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
have the tip guard in place on the spray gun when spray
-
ing.
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. Tell the
doctor
exactly what fluid was injected.
Note
to Physician
:
Injection in 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
.
T
oxicity is a concern
with some exotic coatings injected directly into the blood
stream. Consultation with a plastic surgeon or reconstructive
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 trigger safety in the closed or “safe” position, making the
gun
inoperative. Failure to set the safety latch can result in acci
-
dental
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 dif
fuser operation
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 pressure, trigger
the gun. If the fluid emitted
is not
diffused into an irregular
stream,
replace the dif
fuser immediately
.
Tip Guard
Always
have the tip guard in place on the spray
gun while spray
-
ing. 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 spray
-
ing 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, lock the gun trigger safety im

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 respira
-
tor
as recommended by the fluid and solvent manufacturer
.
System
Pressure
This
sprayer can develop
3000 psi (210 bar) Maximum Working
Pressure
. Be sure that all spray equipment and accessories
used are rated to withstand this pressure. Do not exceed the
maximum working pressure of any component or accessory
used
in the system.
Fluid and Solvent Compatibility
All
chemicals used
in the sprayer must be chemically compat
-
ible
with the wetted parts shown in the
T
echnical Data
on page
44.
Consult your chemical supplier to ensure compatibility
.
Do
not use 1,1,1-trichloroethane, methylene chloride, other ha
-
logenated hydrocarbon solvents or fluids containing such sol-
vents in this equipment, which contains aluminum and/or zinc
parts.
Such
use could result in a serious chemical reaction, with
the possibility of explosion, which could cause death, serious
bodily
injury and/or substantial property damage.
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 skin injection injury or other serious bodily injury or
property
damage.
All
fluid hoses must have 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.
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 ex
-
ist, replace the hose immediately. Do not try to recouple high
pressure hose or mend it with tape or any other device. A re-
paired
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 and gas engine. Do not use fluids or solvents which
are not compatible with
the inner tube and cover of the hose. Do
not
expose Graco hose 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,
contact
the hose supplier or manufacturer for the maximum re
-
sistance
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 un-
grounded
or poorly grounded hose can make
your system haz
-
ardous.
Also read
FIRE OR EXPLOSION HAZARD.
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.
If you experience any static sparking or even a slight shock
while using this equipment, stop spraying 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 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:
connect a ground wire and clamp
(supplied) to a
true
earth ground.
2.
Fluid
hoses:
use only grounded hoses with
a maximum of
500
ft (150 meter) combined hose length to ensure ground
-
ing
continuity
. See
Hose Grounding Continuity.
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
cardboard, 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 skin injection injury, static sparking, or
splashing
by following the flushing procedure given on page 15
of
this manual. Follow the
Pressure Relief Procedure
on page
4, 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.
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
4
before checking
or servicing any part of the sprayer
, to prevent
it
from starting accidentally

ment
des soins medicaux d’urgence.
Ne pas soigner cette blessure
comme
une simple coupure.
Avis
au medecin
: La pénétration des fluides sous la peau est
un
traumatisme. Il est important de traiter chirurgicalement
cette blessure immédiatement. Ne pas retarder le traite-
ment pour effectuer des recherches sur la toxicité. Certains
revêtements exotiques sont dangereusement toxiques
quand ils sont injectés directement dans le sang. Il est
souhaitable de consulter un chirurgien esthétique ou un
chirurgien
spécialisé dans la reconstruction des mains.
Dispositifs de sécurité du pistolet
Avant chaque utilisation, bien s’assure que tous les dispositifs de
sécurité du pistolet fonctionnent correctement. Ne pas enlever ni
modifier
une partie quelconque du pistolet; ceci risquerait
d’entraîner
un
mauvais fonctionnement et des blessures graves.

MESURES
DE
SECURITE CONCERNANT LES TUY
AUX FLEXIBLES
Le
fluide à haute pression circulant dans les tuyaux peut être très dan
-
gereux.
En cas de fuite sur
le tuyau, de fissure, déchirure ou rupture
à
la suite de l’usure, de dégâts ou d’une mauvaise utilisation, les pro
-
jections
de fluide haute pression qui en
proviennent peuvent entraîner
des
blessures graves par pénétration sous la peau ou par contact,
ainsi
que des dégâts matériels.
Tous
les tuyaux flexibles doivent avoir des ressorts spirale de
protection
aux bouts!
Les spirales de protection
contribuent à eviter
la
formation de pliures, de boucles ou de nœuds sur les tuyaux qui
pourraient
entraîner la
rupture du tuyau à l’endroit du raccord ou à
son
voisinagé.
Serrer
fermement tous les raccords avant chaque utilisation. Le fluide
sous
pression peut faire sauter un raccord desserre ou produire un
jet
à haute pression s’échappant par le raccord.
Ne
jamais utiliser un tuyau endommagé. Ne pas essayer de refaire
le raccord d’un tuyau haute pression ni de réparer
le
tuyau avec du
ruban
adhesif ou par tout autre moyen. Un tuyau réparé ne peut pas
résister
au fluide sous pression.
Manipuler
les tuyaux avec precaution et choisir soigneusement leur
chemin.
Ne pas déplacer le fluide en tirant sur le tuyau.
Ne pas utiliser
de
fluides ou de solvants qui ne sont pas compatibles avec l’enveloppe
intérieure
ou extérieure du tuyau. NE P
AS exposer le tuyau à des
températures
supérieures à 82
C (180
F) ou inférieures à –40
C
(–40 F).
Continuité
de la mise à la terre des tuyaux
Une
bonne

PELIGRO DE INYECCION DE FLUIDO
Seguridad
general
Este
equipo genera un fluido a una presión muy alta. El rociado
de la pistola, los escapes de fluido o roturas de los com-
ponentes
pueden inyectar fluido en la piel y el cuerpo y causar
lesiones extremadamente graves, incluyendo a veces la
necesidad de amputación. También, el fluido inyectado o sal-
picado
en los ojos puede causar graves daños.
Nunca apuntar la pistola hacia alguien o alguna parte del
cuerpo. Nunca colocar la mano o los dedos encima de la
boquilla.
Nunca tratar de
“hacer retornar la pintura”; este NO es
un
sistema de rociado de aire.
Siempre tener colocado el protector de la boquilla en la pis-
tolamientras

SEGURIDAD EN EL USO DE LAS MANGUERAS
El fluido que escapa a alta presión por las mangueras puede
ser
muy peligroso. Si en la manguera se desarrolla un
escape,
una
rotura o rajadura debido a cualquier tipo de desgaste, daño
o maltrato, el chorro a alta presión emitido por alli puede causar
una lesion por inyección u otras lesiones corporales graves o
daños
a la propiedad.
!Todas Las Mangueras Para Fluidos Tienen Que Tener
Guardas De Resorte En Ambos Extremos! Estas protegen
las mangueras contra dobleces o retorceduras en los
acoplamientos o cerca de ellos, los que
podrian traducirse en
roturas de la manguera.
Antes
de usarlas, apretar bien
firmes todas las conexiones. El
fluido a alta presión puede desalojar un acoplamiento suelto o
dejar
que por el escape un chorro a alta presión.
Nunca usar una manguera que está dañada. Siempre,
revisarla
en busca de cortaduras, escapes, abrasion, cubierta
abultada, o acoplamientos sueltos o dañados. Si llegara a en
-
contrarse cualquiera de estás condiciónes, reemplazar de in-
mediato la manguera. NO intentar racoplar una manguera de
alta presión o enmendarla con cinta adhesiva u otro matérial
similar. Una manguera que ha sido remendada no aguante el
fluido
a alta presión.
Manejar y pasar cuidadosamente las mangueras. No tirar de
las mangueras para mover el equipo. No usar fluidos o sol-
ventes
que sean incompatibles con el tubo interno y la cubierta
dela manguera. No exponer las mangueras a temperaturas
sobre
82
C (180
F) o bajo –40
C (–40
F).
Continuidad
del circuito de puestá a tierra de la
manguera
La continuidad del circuito de puestá a tierra apropiado es
esencial para mantener conectado a tierra el sistema pul-
verizador. Es indispensable revisar la resistencia eléctrica
máxima
de las mangueras de aire y de fluido por lo menos una
vez
a la semana. Si la manguera no tiene una etiqueta
en la cual
se
especifica la resistencia eléctrica, ponerse en contacto con
el provédor o fabricante de la manguera para la información
sobre
los límites de resistencia. Usar un metro de resistencia en
la
gama apropiade para comprobar la resistencia; si excede los
límites
recomendados, reemplazarla
de inmediato. Es muy ar
-
riesgado
tener una manguera sin puestá a tierra o con la puestá
a tierra en malas condiciónes. Leer también la información
sobre
RIESGO DE INCENDIO O EXPLOSION
, más arriba.
PELIGRO DE INCENDIO O EXPLOSION
El
flujo a alta velocidad del fluido al pasar por la bomba y man
-
guera
crea electricidad estática. Si todas las partes del
equipo
pulverizador no tienen buena tierra, pueden ocurrir chispas,
convirtiendo al sistema en algo peligroso. También, pueden
producirse chispas a enchufar o desenchufar el cordón
electrico
o al usar un motor
de gasolina. estás chispas pueden
inflamar
los vapores de los solventes y el chorro de fluido pul
-
verizado, particulas de polvo y otras sustancias in flamables,
sea
al aire libre o bajo techo, lo que podria causar una explosión
o
incendio y graves lesiones corporales
y daños al a propiedad.
Enchufar siempre la pulverizadora a un tomacorriente que se
encuentre
a por lo menos 6 m (20
pies) de la maquina y del area
que se va a rociar. No enchufar o desenchufar ningún cordón
electrico
en el lugar
donde se está rociando cuando todavia ex
-
ista
la posibilidad de que queden
vapores inflamables en el aire.
Si
ocurre una chispa de electricidad estática o incluso un ligero
choque
electrico mientras se usa el equipo, dejar de pulverizar
de inmediato. Revisar todo el sistema en busca de una tierra
apropiada. No usar de nuevo el sistema hasta haber iden-
tificado
y soluciónado el problema.
Peusta
a tierra
Para
reducir el reisgo de chispas estáticas, conectar a tierra la
pulverisadora
y todo el otro equipo de pulverisar que se use o
se
encuentre en el
lugar que se va a rociar
. Consultar el codigo
electrico
de la localidad para las instrucciónes
sobre las conex

sor, cada uno un enchuf de très patas en buen estádo, a
un
tomacorreinte con puesat a tierra aporpiado. No usar un
adaptador. Totos los cables extensores tienen que tener
très
hilos y una capacidad de 15 amperios.
2.
Mangueras para fluidos:
usar solamente mangueras con
puestá
a
tierra de una longitud combinada de 150 m (500
pies),
para asequrar buena continuidad a tierra. Referirse
también al párrafo sobre continuidad del circuito de

Pressure Relief Procedure
on page 4 whenever
you are instructed to relieve the pressure.
1.
Check the packing nut (216) daily
. Relieve the
pressure. Keep the packing nut 1/3 full of TSL at
all times to help prevent fluid buildup on the piston
rod and the premature wear of the packings.
T

ings to wear prematurely
. Use a round punch or a
brass rod and a lightweight hammer to adjust the
nut.
See Fig. 6.
2.
Clean the fluid filter (66) at least once a day
.
Follow the flushing procedure
on page 15 or refer
to manual 307–273, for the cleaning procedure.
3.
Lubricate the bearing housing (69)
after each 100
hours of operation. Relieve the pressure. Remove
the front cover (49). Fill the cavity in the bearing
housing with SAE 10, non-detergent oil. See Fig.
6.
4.
For very short shutof
f periods, leave the suction
tube in the paint, relieve the pressure, and clean
the spray tip.
5.
Flush the sprayer at the end of each work day
. The
final flush should be mineral spirits. See page 15.
T
o prevent serious damage to the pump, which can
result in poor sprayer performance and costly
repairs, follow these precautions.
Do not allow water or any type of paint to
freeze in the sprayer or the pressure control.
Always flush with a compatible solvent and then
flush again with mineral spirits when you are
done spraying.

Control Adjustment
WARNING
Use
extreme caution when performing this adjustment procedure
to reduce the risk of a fluid injection in
-
jury or other serious injury which can result from component rupture, electric shock, fire, explosion, or moving
parts.
This procedure sets the sprayer to 3000 psi (210 bar)
Maximum Working Pressure
and sets the overpres
-
surization switch (microswitch) to approximately 3600
psi (242 bar).
Perform this procedure whenever the pressure con
-
trol is removed, installed or replaced, and whenever
a new circuit board is installed.
An improper adjustment can cause the sprayer to
over–pressurize and result in component rupture, fire
or explosion. It can also prevent the sprayer from
obtaining the maximum working pressure, resulting in
poor sprayer performance.
Never try to increase the maximum working pressure
beyond 3000 psi (210 bar) by performing these ad
-
justments in any other way
. Normal operation of the
sprayer at higher pressures may result in component
rupture, fire, or explosion. T
o perform this adjust
-
ment, however
, the sprayer pressure must be
tempo-
rarily
increased above the normal working pressure.
Use a
new,
50 ft (15.2 m) spray hose rated for at
least 3000 psi (210 bar) Maximum W
orking Pressure
.
A used, under–rated hose could develop a high–
pressure leak or rupture.
