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
Safety Latch
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.
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 diffuser 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 diffuser 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 placing your fingers or any part of your body close to the
spray tip.
Medical Alert––Airless Spray Wounds
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 . Toxicity 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.
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 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, below, and then remove the spray tip to clean it.
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.
NEVER wipe off build–up around the spray tip until the pressure is fully relieves and the gun safety 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 off the sprayer, when checking
or servicing any part of the spray system, when installing,
cleaning or changing spray tips, and whenever you stop
spraying.
1. Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3. Unplug the power supply cord.
4. Disengage the gun safety latch. Hold a metal part of the gun
firmly to the side of a grounded metal pail, and trigger the gun
to relieve pressure.
1,4,5

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, VERY SLOWLY loosen the tip guard retaining
nut or hose end coupling to relieve pressure gradually, then
loosen completely. Now clear the tip or hose.

MOVING PARTS HAZARD
HOSE SAFETY
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 chemicals 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
This sprayer can develop 2750 psi (190 bar) MAXIMUM
WORKING PRESSURE. Be sure all spray equipment and
accessories used are rated to withstand the 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 compatible
with the wetted parts shown in the TECHNICAL DATA on page
31. Consult your chemical supplier to ensure compatibility.
Do not use 1,1,1-trichloroethane, methylene chloride, other
halogenated hydrocarbon solvents or fluids containing such
solvents 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.
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 property damage.
ALL FLUID HOSES MUST HAVE 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
pressure 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 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. 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 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, contact the hose supplier or manufacturer for the maximum resistance 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 unplugging 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 the 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, 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: plug the power supply cord, or extension cord – each
equipped with an undamaged, three–prong plug, into a properly grounded outlet. Do not use an adapter . All extension
cords must have three wires and be rated for 15 Amps.
2. Fluid hoses: use only grounded hoses with a maximum f 500
ft (150 m) combined hose length to ensure grounding continuity. See Hose Grounding Continuity above.
3. Spray gun: obtain grounding through connection to a properly
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 fluid injection injury, static sparking, or
splashing by following the flushing procedure given on page
12 of this manual. Follow the PRESSURE RELIEF PROCEDURE 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.

Le fluide à haute pression circulant dans les tuyaux peut être
très dangereux. 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 projections 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 2 BOUTS!
Les spirales de protection contribuent à éviter 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
voisinage.
SERRER FERMEMENT tous les raccords avant chaque utilisation. Le fluide sous pression peut faire sauter un raccord
desserré 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 adhésif 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 que ne sont pas compatibles avec l’enveloppe intérieur ou extérieure de tuyau. NE PAS exposer le tuyau à fluides 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 continuité de la mise à la terre des tuyaux est essentielle pour maintenir la mise à la terre de l’ensemble de
vaporisation. Vérifiez la résistance électrique de vos tuyaux à
fluides et à air, au moines une fois par semaine. Si votre tuyau
ne comporte pas d’étiquette qui précise la résistance électrique maximum, prenez contact avec le fournisseur de tuyaux
ou la fabricant pour avoir les limites de résistance maximum.
Utilisez un mètre de résistance de la gamme appropriée pour
votre tuyau et vérifiez la résistance. Si celle–ci dépasse les
limites recommandées, remplacez le tuyau immédiatement.
Un tuyau sans mise à la terre ou avec une mise à la terre incorrecte peut entraîner des risques pour votre système. Lisez
aussi LES RISQUES D’INCENDIE OU D’EXPLOSION.
RISQUES D’INCENDIE OU D’EXPLOSION
De l’électricité statique est produite par le passage du fluide à
grande vitesse dans la pompe et dans les tuyaux. Si toutes
les pièces de l’appareil de pulvérisation ne sont pas convenablement reliées ou à la masse ou à la terre, des étincelles
peuvent se produire et l’appareil risques d’être dangereux.
Des étincelles peuvent Également se produire à l’occasion du
branchement ou du débranchement du cordon d’alimentation
ou de l’utilisation d’un moteur à essence. Les étincelles sont
suffisantes pour allumer les vapeurs de solvants et le fluide
pulvérisé, les fines particules de poussière ainsi que d’autres
substances inflammables, quand on pulvérisé à l’intérieur ou
à l’extérieur, et elles peuvent causer un incendie ou une explosion, ainsi que des blessures graves et des dégâts matériels. Toujours brancher le pulvérisateur dans une prise se
trouvant à au moins 6 m (20 pieds) de l’appareil et de l’endroit
où se fait la pulvérisation. Ne pas brancher ou débrancher un
cordon d’alimentation quel qu’il soit dans la zone où se fait la
pulvérisation quand il y a le moindre risque que ds vapeurs
encore présentes dans l’air prennent feu.
S’il se produit des étincelles d’électricité statique, ou si vous
ressentez la moindre décharge, ARRETEZ IMMEDIATEMENT
LA PULVERISATION. Vérifiez que le système avant que le
problème soit identifié et corrigé.
Mise à la terre ou à la masse
Pour réduire les risques de production d’étincelles d’électricité
statique, le pulvérisateur et tous les équipement utilisés ou se
trouvant dans la zone de pulvérisation doivent être reliés à la
terre ou à la masse. Pour connaître le détail des instructions
de mise à la terre dans la région et le type particulier d’équipement, CONSULTER le code ou les réglementations électriques locales. S’ASSURER que tous le équipements de pulvérisation suivants sont bien reliés à la terre:
1. Pulvérisateur: Brancher le cordon d’alimentation ou la
rallonge qui doivent être équipes d’une prise à 3 fiches en bon
état, dans une prise de courant convenablement mis à la terre. Ne pas utiliser d’adapteur . Toutes les rallonges doivent
avoir 3 fils et être prévues pour 15 ampères.
2. Pistolet:Réaliser la mise à la terre en le raccordant à une
tuyau flexible et à une pulvérisateur déjà convenablement reliés à la terre.
3. Tuyaux flexibles: Afin d’assurer la continuité de la mise à la
terre, n’utiliser que des tuyaux comportant une mise à la terre
et ayant une longueur maximum combinée de 150 m (1500
pieds). Se reporter également au paragraphe, “Continuité
du circuit de mis à la terre des tuyaux”.
4. Récipient d’alimentation: observer le code ou les réglementations locales.
5. Objets, matériel ou surfaces recevant la pulvérisation: observer le code ou les réglementations locales.
6. Tous le seaux de solvant utilisés pour le rinçage: observer le
code ou les réglementations locales. N’utiliser que des seaux
métallique conducteurs de l’électricité. Ne pas mettre le seau
sur une surface non conductrice comme sur du papier ou du
carton car cela interromprait la continuité de la mise à la terre.
7. Pour conserver la continuité de la mise à la terre quand on rincé le matériel ou quand on libère la pression, toujours maintenir une partie métallique du pistolet fermement appuyée contre le côté d’un seau en métal puis appuyer sur la détente du

PELIGRO DE INYECCION DE FLUIDO
Seguridad general
Aparatos de seguridad de la pistola pulverizadora
Este equipo general un fluido a una presión muy alta. El
rociado de la pistola, los escapes de fluido o roturas de los
componentes 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
salpicado en los ojos puede causar graves daños.
Asegurar que todos los aparatos protectores de la pistola
están funcionando bien antes de cada uso. No sacar ni
modificar ninguna pieza de la pistola pues podría causar el
malfuncionamiento de la misma con las consiguientes
lesiones personales.
Pestillo de seguridad
Cada vez que se deje de pulverizar, aunque sea por un breve
momento, siempre colocar el pestillo de seguridad en la
posición “cerrada”, lo que deja la pistola inoperante. El no
hacerlo puede llevar al disparo imprevisto de la pistola.
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.
Difusor
SIEMPRE tener colocado el protector de la boquilla en la
pistola mientras se está pulverizando.
El difusor de la pistola dispersa el chorro pulverizado y reduce
el riesgo de inyección cuando no está instalada la boquilla.
Revisar con regularidad el funcionamiento del difusor. Seguir
el procedimiento de descarga de presión, dado más abajo,
y después sacar la boquilla. Apuntar la pistola a un balde
metálico, sosteniéndola bien firme contra él. Utilizando la
presión más bajo posible, disparar la pistola. Si el fluido
emitido no sale disperso en un chorro irregular, reemplazar de
inmediato el difusor.
SIEMPRE seguir el procedimiento de descarga de presión,
dado más abajo, antes de limpiar o sacar la boquilla o de dar
servicio a cualquier del sistema.
NUNCA tratar de parar o desviar los escapes con la mano o
el cuerpo.
Asegurar que todos los aparatos de seguridad del equipo
están funcionando bien antes de cada uso.
Protector de la boquilla
SIEMPRE tener el protector de la boquilla colocado en la
pistola mientras se está pulverizando. Este protector llama la
atención contra el peligro de inyección y ayuda a reducir, pero
no evita, la colocación accidental de los dedos o cualquier
otra parte del cuerpo cerca de la boquilla.
Tratamiento médico
Si pareciera que un poco de fluido penetró la piel, conseguir
TRATAMIENTO MEDICO DE URGENCIA DE INMEDIATO.
NO TRATAR LA HERIDA COMO UN SIMPLE CORTE. Decir
al médico exactamente cua fluido fue.
Seguridad de la boquilla pulverizadora

llegara a obstruirse mientras está pulverizando, enganchar el
pestillo de la pistola de inmediato. SIEMPRE seguir el
procedimiento de descarga de presión y después sacar
la boquilla para limpiarla
NUNCA limpiar la acumulación de pintura alrededor de la boquilla antes de que se haya descargado por completo la presión y el pestillo esté enganchado.
Aviso al médico: Si se llega a inyectar este fluido en la piel se
causa una lesión traumática. Es importante tratar quirúrgicamente la lesión a la brevedad posible. No demorar el tratamiento para investigar la toxicidad. La toxicidad es algo de
sumar importancia en algunas pinturas exóticas cuando se inyectan directamente al torrente sanguíneo. Sirá conveniente
consultar a un especialista en cirugía plástica o reconstructiva
de las manos.
PROCEDIMIENTO DE DESCARGA DE PRESION
Para reducir el riesgo de sufrir graves lesiones corporales,
incluyendo la inyección de fluidos, salpicaduras en los ojos o
la piel, o lesiones causadas por piezas en movimiento, siempre seguir este procedimiento al apagar la máquina pulverizadora, al revisar, ajustar o limpiar el sistema, o al cambiar las
boquillas.

materiales y productos químicos incompatibles, o utilización
de piezas dañadas o desgastadas, puede hacen que se
rompan y causen la inyección de fluido u otras lesiones corporales graves, incendio, explosión o daños a la propiedad.
Siempre usar gafas, guantes, vestimentas protectoras y un
respiradero, tal como recomiendan los fabricantes del fluido y
del solvente.
Presión del sistema
Esta pulverizadora puede desarrollar 190 barías (2750 psi) de
PRESION DE TRABAJO MAXIMA. Asegurar que todo el equipo pulverizador y sus accesorios tienen la capacidad para
aguantar la presión máxima de trabajo de ningún componente
o accesorio de este sistema.
Compatibilidad de fluido
Siempre leer las instrucciones del fabricante del fluido y
solvente antes de usarlos en esta pulverizadora.
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 desarrola un escape,
una rotura o rajadura debido a cualquier tipo de desgaste,
daño o maltrato, el chorro a alta presión emitido por allí puede
causar una lesión por inyección u otras lesiones corporales
graves o daños a la propiedad.
MANEJAR Y PASAR CUIDADOSAMENTE LAS MANGUERAS. No tirar de las mangueras para mover el equipo. No
usar fluidos o solventes que sean incompatibles con el tubo
interno y la cubierta de la manguera. NO exponer las mangueras a temperaturas sobre 82) C (180_F) o bajo -40_C
(-40_ F).
¡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 podrían
traducirse en roturas de la manguera.
Continuidad del circuito de puesta a tierra
de la manguera
Antes de usarlas, APRETAR bien firmes todas las conexiones. El fluido a lata presión puede desalojar un acoplamiento
suelto o dejar que pro él escape un chorro a alta presión.
NUNCA usar una manguera que está dañada. Siempre revisarla en busca de cortaduras, escapes, abrasión, cubierta abultada, o acoplamientos sueltos o dañados. Si llegara a encontrarse cualquiera de estas condiciones, reemplazar de inmediato la
manguera. NO intentar reacoplar una manguera de alta presión
o enmendarla con cinta adhesiva u otro material similar. Una
manguera que ha sido remendada no aguante el fluido al alta
presión.
La continuidad del circuito de puesta a tierra apropiado es
esencial para mantener conectado a tierra el sistema pulverizador. 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 máximum, ponerse
en contacto con el proveedor o fabricante de la manguera
para la información sobre los límites de resistencia. Usar un
metro de resistencia en la gama apropiada para comprobar la
resistencia; si excede los lites recomendados, reemplazarla
de inmediato. Es muy arriesgado tener una manguera sin
puesta a tierra o con la puesta a tierra en malas condiciones.
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
manguera crea electricidad estática. Si todas las partes del
equipo pulverizador no tienen buena tierra, pueden ocurrir
chispas, convirtiéndo al sistema en algo peligroso. También,
pueden producirse chispas al enchufar o desenchufar el cordón eléctrico o al usar un motor de gasolina. Estas chispas
pueden inflamar los vapores de los solventes y el chorro de
fluido pulverizado, partículas de polvo y otras sustancias
inflamables, sea al aire libre o bajo techo, lo que podría
causar una explosión o incendio y graves lesiones corporales
y daños a la propiedad. Enchufar siempre la pulveriszadora a
un tomacorriente que se encuentre a por lo menos 6 m (20
pies) de la máquina y del área que se va a rociar. No enchufar
o desenchufar ningún cordón eléctrico en el lugar donde se
está rociando cuando todavía exista la posibilidad de que
queden vapores inflamables en el aire.
Si ocurre una chispa de electricidad estática o incluso un ligero choque eléctrico mientras se usa el equipo, DEJAR DE
PULVERIZAR DE INMEDIATO. Revisar todo el sistema en
busca de una tierra apropiado. No usar de nuevo el sistema
hasta haber identificado y solucionado el problema.
Puesta a tierra
Para reducir el riesgo de chispas estáticas, conectar a tierra la
pulverizadora y todo el otro equipo de pulverizar que se use o
se encuentre en el lugar que se va a rociar. CONSULTAR el
código eléctrico de la localidad para las instrucciones sobre
las conexiones a tierra exigidas para la zona y tipo de equipo.
ASEGURAR de conectar a tierra todo este equipo
pulverizador:
1. Pulverizadora: enchufar el cordón eléctrico, o cable estensor,
cada uno con un enchuf de tres patas en buen estado, a un
tomacorriente con puesta a tierra apropiado. No usar
un
adaptador. Totos los cables extensores tienen que tener tres
hilos y una capacidad de 15 amperios.
2. Mangueras para fluidos: usar solamente mangueras con
puesta a tierra de una longitud combinada de 150 m (500
pies), para asegurar buena continuidad a tierra. Referirse
también al párrafo sobre continuidad a tierra de la manguera.
3. Pistola: hacer la puesta a tierra conectándola a una manguera de fluido y pulverizadora bien conectadas a tierra.
4. Suministrar un recipiente: de acuerdo al código local. Usar
solamente baldes de metal, que sean conductivos. No
colocar el balde en una superficie no conductiva, como papel
o cartón, que interrumpe la continuidad a tierra.
5. Objeto que se está rociando: de conformidad con el código
local.
6. Todos los baldes de solvente usados durante el lavado, de
conformidad con el código local.
7. Para mantener la continuidad a tierra durante el lavado o descarga de presión, siempre apoyar una parte metálica de la
pistola bien firme contra el costado de
balde de metal ,
después apretar el gatillo.
Seguridad durante el lavado
Para reducir el riesgo de que se inyecte o salpique fluido en la
piel, o que ocurra una descarga de electricidad estática, siempre seguir las INSTRUCCIONES PARA EL LAVADO, dadas
en la página 12. Seguir el procedimiento de descarga de
presión en la página 6, y quitar la boquilla de metal y usar le
presión más baja posible de fluido durante el lavado.

SETUP
WARNING
To reduce the risk of serious bodily injury
caused by static sparking, fluid injection or
over–pressurization and rupture of the hose
or gun:
1. Always use flexible, grounded hose at
least 50 feet (15.2 m) long.
1. Ground the sprayer and all objects being
sprayed. Read FIRE OR EXPLOSION
HAZARD on page 3.
2. Never use a wire braid hose; it is too rigid to act as a pulsation dampener.
2. Do not operate the spray gun without a
tip guard in place.
3. Never install any shutoff device between
the fluid filter and the first 50 feet (15 m)
of hose. See Fig 1.
3. Be sure all parts added to the sprayer
are rated for at least 2750 psi (190 bar)
Maximum Working Pressure.
1. Connect a 50 foot spray hose and a gun to
the 1/4 npsm(m) fluid outlet nipple. For
more flexible gun movement, install a 3 foot
(0.9 m), 3/16 inch ID diameter hose between
the gun and main spray hose.
DO NOT use thread sealant on the hose and
gun connections. DO NOT install the spray tip
until the system is primed.
2. Fill the packing nut/wet–cup 1/3 full with
Throat Seal Liquid, supplied. Keep it filled to
help extend the life of the packings and the
pump.
3. Check the electrical service. It must be
120 VAC, 60 Hz, 15 Amp (minimum). The
electrical outlet must be properly grounded.
DO NOT remove the grounding prong of the
plug, and do not use an adapter.
Extension cords up to 100 feet (30 m) of 3
wire, 12 gauge (minimum) can be used.
Longer lengths may affect sprayer
performance. Use more spray hose to reach
the spray area, if needed.
8
CAUTION
To avoid damaging the pressure control, follow these precautions.
4. Plug the power supply cord into an outlet
located at least 20 feet (6 m) from the spray
area. This reduces the chance of a spark igniting the spray vapors or dust particles.
5. Flush the pump to remove the lightweight
test oil which was left in it after factory testing.
See FLUSHING GUIDELINES on page 12.
6. Prepare the paint according to the instructions on the paint can. Strain the paint through
a fine nylon mesh bag to remove particles that
could clog the spray tip.

Procedure Warning on page 9. Use a solvent–soaked brush to clean the tip.
b. If the spray tip clogs, engage the gun
safety latch, shutoff and unplug the sprayer, and open the pressure drain valve to
relieve pressure. Loosen the tip guard retaining nut slowly to relieve any additional
pressure, and then remove the spray tip to
clean it. See the instructions supplied with
your spray tip for cleaning clogs.
SHUTDOWN AND CARE
1. Check the packing nut/wet–cup daily.
Relieve pressure. Keep the wet–cup 1/3 full of
Throat Seal Liquid to help prevent fluid buildup on the piston rod and premature wear of
packings. Tighten the packing just enough to
stop leakage. Overtightening may cause binding and excessive packing wear. See Fig 5.
3. For very short shutoff periods, leave the
suction tube in the paint, relieve pressure, unplug the sprayer, and clean the spray tip.
2. Flush the sprayer at the end of each work
day and fill it with mineral spirits to help prevent pump corrosion and freezing. See
FLUSHING GUIDELINES on page 12.
5. Secure the suction hose to the brackets on
the side of the cart.
CAUTION
Never leave water or any paint in the sprayer
overnight to prevent pump corrosion and to
prevent the fluid from freezing in the pump
and pressure control which can cause loss of
pressure, stalling or serious sprayer damage.
Always use mineral spirits for the final flush,
relieve pressure, and leave the mineral spirits
in the sprayer.
4. Coil the hose around the top of the shroud
and rest it on top of the hose rack when storing it, even for overnight, to help protect the
hose from kinking or damage.
PACKING NUT/WETCUP
Keep filled with TSL during
operation. Tighten nut by

FLUSHING GUIDELINES
When To Flush
CAUTION
NEVER leave water in the sprayer if there is
the slightest chance it could freeze. Flush out
the water with mineral spirits. If water freezes
in the pressure control tube, it prevents the
sprayer from being started and causes serious damage to the pressure control.
1. New Sprayer. Flush out the test oil.
Before using water-base paint, flush with
mineral spirits, followed by a soapy water
flush, and then a clean water flush.
Before using oil-base paint, flush with mineral spirits, only.
2. Changing Colors. Flush with a compatible
solvent such as mineral spirits or water.
How To Flush
1. Relieve pressure. See page 9.
2. Remove the filter bowl and screen; see manual 307–273. Clean the screen. Install the bowl

APPLICATION METHODS
Hold the gun perpendicular to the surface. Keep
the gun at an even 12 to 14 in. (300–356 mm)
from the surface you are spraying. See Fig 8.
Begin moving the gun horizontally at a steady
rate. Start the spray stroke off the target surface
and pull the trigger as the gun is moving. Then,
while the gun is still moving, and as you approach
the other edge of the surface, release the trigger.
This method avoids excess paint buildup at the
end of each stroke.
The best way to control the rate of coverage is
with the gun tip size. A small tip orifice applies
less paint. A larger tip orifice applies more paint.
The width of the pattern depends on the fan pattern of the tip you choose.
Do not try to increase coverage by increasing the
fluid pressure! Use the lowest pressure needed
for good results. This prolongs the life of your
sprayer and reduces paint lost by overspray.
For interior corners aim the gun toward the center
of the corner to be sprayed. By dividing the spray
pattern this way, the edges on both sides are
sprayed evenly. See Fig 10.
RIGHT
Fig 8
WRONG
Move the gun at a speed that provides a full, wet
coating to be applied without runs or sags. Lap
each stroke 50% over the previous stroke to produce a uniform paint thickness. Spray in a uniform
pattern from right to left and then left to right for a
professional finish. See Fig 9.
Fig 10
If there is a wind, angle the spray pattern into the
wind to minimize drifting. Paint from the ground to
the roof.
Shrubs. Tie back shrubs with rope and stakes.
Cover them with a dropcloth as the painter approaches the area. Remove the dropcloth as soon
as the area is painted to prevent damage.
Concrete walks. If the walkways will be walked
on, cover them with a canvas dropcloth to avoid
slipping. Otherwise a plastic cloth can be used.
OVERLAP EACH STROKE 50%
Fig 9
Electrical outlets and lamps. Protect electrical outlets with masking tape. Cover lamps with plastic
bags secured with masking tape.
Nearby objects. Move portable objects upwind of
the surface to be sprayed. If there is a nearby
home, make a protective barrier by hanging plastic dropcloths between two long poles.

the risk of overpressurization which can result
in component rupture, fire or explosion. Improper calibration may also prevent the
sprayer from obtaining the maximum working
pressure, resulting in poor sprayer
performance.

3. Open the needle valve slightly. Turn the pressure adjust knob (A) to the minimum setting.
4. Plug in the sprayer and turn the switch ON.
Turn the pressure adjusting knob clockwise
just enough to start the sprayer. Fully prime
the hose.
NOTE: In Step 5, the slower the pressure is
raised, the easier it is to note the exact
stall pressure. Closing the needle valve
quickly causes the pressure to rise too
fast which gives a false reading.
5. Open the needle valve a just enough to allow
the pump to run continuously, and turn the
pressure control knob to maximum. Very slowly start to close the needle valve. Observe the
pressure at which the pump stalls, which
should be approximately 2750 psi (190 bar).
If the pressure is lower than 2750 psi (190 bar):
Unplug the sprayer and relieve pressure. Turn
the adjustment nut (B) counterclockwise 1/8
turn or less. Repeat steps 5 and 5.
If the pressure is higher than 2750 psi (190 bar):
Unplug the sprayer and relieve pressure. Turn
the adjustment nut (B) clockwise 1/8 turn or
less. Repeat steps 4 and 5. Repeat until the
proper stall pressure is obtained.
6. Plug in the sprayer, turn it on, close the needle
valve, and set the pressure at maximum. Allow the sprayer to run until it stalls.
7. Open the needle valve very slowly while observing the pressure gauge. Check to see if
the pressure drops to approximately 2300 psi
(161 bar) before starting again.
If the pressure is lower than 2300 psi (161 bar):
Shut off and unplug the sprayer, but do not
relieve pressure. Turn the differential wheel
(C) counterclockwise just one notch and repeat Steps 4 and 5. Check the pressure drop
again, and repeat if necessary.
NOTE: If you adjust the differential wheel, recheck the stall pressure (steps 4 and 5) to
be sure it has not changed.
8. Relieve pressure. Flush the water out with
mineral spirits. Relieve pressure. Remove the
test equipment.
