Introduction
GM5000 BASIC COMPONENTS
NOTE: Refer to Fig.1.
Your new GM5000 Sprayer functions and operates differently than other airless paint sprayers. This section will
help you become familiar with the sprayer before operating it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, the pressure adjusting knob, and a pressuresensing device. The pressure control engages and disengages the clutch to control pressure.
Engine
The engine is a 5 horsepower, four stroke, gasoline engine. Its function is to drive the displacement pump to
supply paint. An adjustable throttle allows you to adjust
engine speed for large or small orifice spray tips. When
the oil level is too low, the engine shuts off automatically.
If you try to start the engine without refilling the oil, a light
illuminates to alert you to the problem, and to protect the
engine from damage.
Clutch
The clutch is engaged by the electric power generated by
the gasoline engine. The power is controlled by the pressure switch.
Drive Assembly
The permanently greased drive assembly transfers power from the gasoline engine to the displacement pump.
Displacement Pump
The positive–displacement, volume-balanced pump provides equal fluid delivery on both the up and down pump
strokes. The pump has a wetcup which, when filled with
Graco Throat Seal Liquid, 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 spray tip. The filter includes a reusable element, and a pressure drain valve for relieving fluid pressure.
Hoses
The grounded, nylon spray hoses have spring guards on
both ends. The 50 ft. (15.2 m) hose has a 1/4 in. ID. The
3 ft. (0.9 m), 3/16 in. ID whip hose provides more flexible
gun movement. The nylon hose material acts as a pulsation dampener to absorb pressure fluctuations.
Spray Gun & RAC IV DripLess Tip Guard
Graco high pressure spray guns have a trigger safety
which prevents accidental triggering when the safety is
engaged. See Fig. 1. The gun provided with the sprayer
also has a filter for final paint straining. The Reverse-AClean IV (RAC IV) SwitchTip uses high pressure fluid
to remove clogs from the spray tip without removing the
spray tip from the gun. The Reverse-A-Clean IV DripLess tip guard is a safety feature which helps reduce
the risk of a fluid injection injury.

WARNINGS
High Pressure Spray Can Cause Serious Injury. For Professional Use Only.
Observe All Warnings. 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 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 Wounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREA T 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.
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 injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set
the trigger 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.
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 trigger safety
latch immediately. ALWAYS follow the Pressure Relief Procedure, below, and then remove the spray tip to clean it.
NEVER wipe off build–up around the spray tip until the pressure
is fully relieved and the gun safety is engaged.
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious 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 trigger safety latch.
2 Turn the engine ON/OFF switch to OFF.
3 Flip the pressure control switch to OFF.
4 Disengage the trigger 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.
1,5

5 Engage the trigger safety latch.
6 Open the pressure drain valve. Leave the valve open until
you are ready to spray again.
7 Disconnect the spark plug cable.
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
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 above be-
fore 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 eyes or on
skin, or other serious 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
worn or damaged parts immediately.
replace
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.
Noise
Ear protection is recommended when the sprayer is operating.
Refer to the Sound Level in the Technical Data on page 43.
System Pressure
This sprayer can develop 3000 psi (210 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
43. 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 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 fluid injection injury or other serious 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.
FLUID INJECTION 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 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 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 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.
GASOLINE ENGINE HAZARD
NEVER fill the fuel tank while the engine is running or hot. Fuel
spilled on a hot surface can ignite and cause a fire.
ALWAYS pour fuel in slowly to avoid spilling. Also read Fire Or
Explosion Hazard, above, and Fueling on page 11.
NEVER operate the engine in a closed building unless the engine exhaust is piped outside. The exhaust contains carbon
monoxide, a poisonous, odorless and invisible gas which can
cause serious illness and even death of inhaled.
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.

sécurité fonctionnent correctement.
Soins médicaux
En cas de pénétration de fluide sous la peau: DEMANDER IMMEDIATEMENT DES SOINS MÉDICAUX D’URGENCE. Ne
pas soigner cette blessure comme une simple coupure.
Avis au médecin: La pénétration des fluides sous la peau est
un traumatisme. Il est important de traiter chirurgicalement
cette blessure immédiatement. Ne pas retarder le traitement
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 esthétiques 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.
Verrou de sécurité
A chaque fois que l’on s’arrête de pulvériser , même s’il s’agit
d’un court instant, toujours mettre le verrou de sécurité du pistolet sur la position, “fermée” ou “sécurité” (“safe”), pour empêcher
le pistolet de fonctionner. Si le verrou de sécurité n’est pas mis,
le pistolet peut se déclencher accidentellement.
Diffuseur
Le diffuseur du pistolet sert à diviser le jet et à réduire les risques
d’injection accidentelle quand l’ajutage n’est pas en place. Vérifier le fonctionnement du diffuseur régulièrement. Pour cette vérification, détendre la pression en observant la Marche à Suivre

RISQUES EN CAS DE MAUVAISE UTILISATION DU MATERIAL
Consignes générales de sécurité
Toute utilisation anormale de l’appareil du pulvérisation ou des
accessoires comme, par exemple, la mise sous une pression
excessive, les modifications de pièces, l’utilisation de produits
chimiques et de matières incompatibles et l’utilisation de pièces
usées ou abîmées peut causer des dégâts à l’appareil ou des
ruptures de pièces et entraîner une injection de liquide ou d‘autres blessures sérieuses, un incendie, une explosion ou d’autres dégâts.
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.
Toujours porter une protection pour les yeux, de gants, des vêtements protecteur et un dispositif pour la respiration correspondant
aux recommandations des fabricants de fluides et solvants.
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.
Pression
Ce pulvérisateur peut produire une PRESSION MAXIMUM DE
TRAVAIL 210 bar (3000 lb/po. @) S’assurer que tous les éléments du pulvérisateur et ses accessoires sont conçus pour résister à la pression maximum de travail de ce pulvérisateur. NE
PAS dépasser la pression maximum de travail d’aucun des éléments ou accessoires utilisés avec cet appareil.
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).
Compatibilité chimique des corps
BIEN S’ASSURER que tous les corps des solvants utilisés sont
chimiquement compatibles avec les parties mouillées indiquées
dans les “Données techniques”, à page 43. Toujours lire soigneusement les documents et brochures du fabricant des fluides et solvants utilisés avant de s’en servir dans ce pulvérisateur.
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.
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.
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.

Lea y entienda todo el manual de instrucciónes antes de manejar el equipo.
PELIGRO DE INYECCION DE FLUIDO
Seguridad general
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.
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 pistola
mientras se está pulverizando.
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.
Tratamiento médico
Si pareciera que un poco de fluido penetró la piel, conseguir
TRATAMIENTO MEDICO DE URGENCIA DE INMEDIA TO.
NO TRATAR LA HERIDA COMO UN SIMPLE CORTE. Decir
al
médico exactamente cua fluido fue.
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.
Aparatos de seguridad de la pistola pulverizadora
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.
Difusor
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.
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.
Seguridad de la boquilla pulverizadora
Tener mucho cuidado al limpiar o cambiar las boquillas. Si 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.
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.
1 Enganchar el pestillo de seguridad de la pistola.
2 Mover el interruptor de parada del motor a OFF.
3 Mover el interruptor de control de presión a OFF.

PELIGRO POR MAL USO DEL EQUIPO
Seguridad general
Cualquier mal uso del equipo pulverizador o los accesorios, tal
como sobre presurización, modificación de piezas, uso de 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 210 barías (3000 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 en la página 43.
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.
¡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.
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.
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).
Continuidad del circuito de puesta a tierra de la
manguera
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. T ambién, 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.
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: Conectar el alambre de tierra y la abrazadera
(suministrada) a una buena conexión a tierra.
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 15. Seguir el procedimiento de descarga de presión
en la página 8, y quitar la boquilla de metal y usar le presión más
baja posible de fluido durante el lavado.
PRECAUCIONES PARA LOS MOTORES DE GASOLINA
NUNCA llenar el tanque de combustible mientras el motor está
funcionando o caliente. El combustible derramado en una superficie caliente puede encenderse y provocar un incendio.
SIEMPRE verter el combustible lentamente para evitar derrames. Leer PELIGRO DE INCENDIO O EXPLOSION.
NUNCA hacer funcionar el motor en un edificio cerrado sin en–
caminar los gases de escape hacia el aire libre. Los gases de
escape contienen monóxido de carbono, un gas venenoso, sin
olor e invisible que podría causar enfermedades graves, incluso la muerte, al inhalarse.

Pressure Relief Procedure
To reduce the risk of serious injury, including fluid injection, splashing in the eyes or on the skin, or injury from
moving parts, always follow this procedure when you
shut off the sprayer, when checking, adjusting or cleaning the system, and when changing spray tips.
1. Engage the trigger safety latch.
2. Turn the engine ON/OFF switch to OFF.
3. Turn the pressure control switch to OFF.
4. Disengage the trigger safety latch. Hold a metal
part of the gun firmly to the side of a grounded
metal pail, and trigger the gun.
5. Engage the trigger safety latch.
6. Open the fluid pressure drain valve and leave it
open until you start the sprayer again.
7. Disconnect the spark plug.
If you suspect the hose or spray tip is
completely
clogged or that pressure is not fully relieved after following the steps above, VERY SLOWLY loosen the tip
guard or hose end coupling to relieve pressure gradually. Now clear the tip or hose obstruction.
Check everything in the chart before disassembling the sprayer.

DO NOT lose the thrust balls (20c or 19d) located at
each end of the gear cluster, or allow them to fall between the gears. The ball, which is heavily covered
with grease, usually stays in the shaft recesses, but
could be dislodged. If the balls are caught between
the gears and not removed, they will seriously damage the drive housing. If the balls are not in place, the
bearings will wear prematurely.
7. Liberally apply bearing grease to the gear cluster
(18). A tube of grease is supplied with each replacement gear cluster . Use a full 6 oz. (160 grams) of
grease. Be sure the thrust balls (20c and 19d) are in

WARNING
USE EXTREME CAUTION WHEN PERFORMING THIS CALIBRATION PROCEDURE to reduce the risk of a
fluid injection injury or other serious injury, which can result from component rupture, electric shock, fire, explosion or moving parts.
NEVER EXCEED 3000 psi (210 bar) MAXIMUM
This procedure sets the sprayer to 2600–3000 psi
WORKING PRESSURE. Normal operation of the

control assembly is removed and reinstalled, or replaced, to be sure the sprayer is properly calibrated.
Improper calibration can cause the sprayer to over–
pressurize and result in component rupture, fire or explosion. It may also prevent the sprayer from obtaining
the maximum working pressure, resulting in poor
sprayer performance.
NEVER attempt to increase the fluid outlet pressure by
performing these calibrations in any other way
.
Service Tools Needed
NEW 50 foot (15.2 m), 3000 psi (210 bar), flexible nylon,
airless spray hose, p/n 223–541
0–5000 psi (0–350 bar) fluid–filled pressure gauge, p/n
102–814
NEW spray tip, size 0.025 to 0.029
3/8 in. ignition wrench or nut driver
5 gallon pail and water or mineral spirits
Swivel, p/n 156–823
Nipple, p/n 162–453
Tee, p/n 104–984
ALWAYS use a new 50 foot (15.2 m) spray hose, rated
for at least 3000 psi (210 bar) MAXIMUM WORKING
PRESSURE, when performing this procedure. A used,
under–rated hose could develop a high pressure leak
or rupture.
AVOID touching the wires in the pressure control assembly when the control box cover is removed, to reduce the risk of electric shock.

Removing and Installing the Pump
WARNING
Installing the pump
To reduce the risk of serious injury, including fluid injection always follow the Pressure Relief Procedure
Warning on page 14 before checking, adjusting,
cleaning or shutting of f the sprayer. Disconnect the
spark plug!
Removing the pump
See Fig. 26.
1. Flush the pump. Relieve pressure. See page 14.
2. Hold the intake valve (423) with a wrench and unscrew the suction tube (30). Remove the hose (59).
For upright carts, remove the spring clips (112,114)
and drain hose (113).
3. Push the retaining spring (26) up. Push the pin (25)
out the rear.
4. Loosen the locknut (27). Unscrew the pump. See below for how to repair the pump.
1. Screw the pump about 3/4 of the way into the bearing
housing (21). Hold the pin (25) up to the pin hole on
the connecting rod (22) and continue screwing in the
pump until the pin slides easily into the hole.
2. Back off the pump until the top threads of the pump
cylinder are flush with the face of the bearing housing
and the outlet nipple faces back.
3. Push the retaining spring (26) into the groove all the
way around the connecting rod. Tighten the locknut
(27) to 79 ft–lb (97 N.m) using a 2 1/4 in. open end
wrench and a light hammer.
4. Install the front cover and screws. Connect the pump
outlet hose. Install the suction tube parts. For Upright

Displacement Pump Repair
4. To disassemble the rest of the pump, remove the
packing nut (416) and plug (405). See Fig. 33.
5. Use a plastic mallet to tap the piston rod (424) down.
Pull the rod out through the bottom of the cylinder.
6. Remove the throat packings. See Fig. 33.
WARNING
Always use the special sleeve removal tool,
P/N
220–991, to remove the sleeve. Other removal methods could cause the pump to rupture, resulting in serious injury. If the sleeve cannot be removed easily using the tool, return the sleeve and cylinder to your
Graco distributor for removal.
7. Remove the sleeve. Screw the large nut (B) of the
tool into the top of the cylinder (419). Screw down the
rod (A) to push the sleeve out. Remove the tool. See
Fig. 29.
8. Clamp the flats of the piston rod (424) in a vise. Loosen the retaining nut (411). Unscrew the piston valve
(422). See Fig. 30.
9. Disassemble the piston valve (422). See Fig. 30.
3. Alternate leather and plastic packings as shown in
Fig. 30. The lips of the throat “V” packings must face
down. The lips of the piston “V” packings must face
up. The lips of the U–cup seal (403) face down. Incorrect installation damages the packings and causes
the pump to leak.
4. Soak leather packings in oil before reassembling the
pump.
Reassembly Procedure
1. Stack the backup washer (414), seal (403*), female
gland (415*), alternate the packings (412*,406*), and
then male gland (410*) onto the piston valve (422).
See Fig. 30.
2. Tighten the packing retaining nut (411) onto the piston valve (22) to the torque specified in Fig. 30.
3. Put the ball (425*) on the piston valve (422). See
Fig. 30.
CAUTION
Step 5, tightening the piston valve into the rod, is critical. Follow the procedure carefully to avoid damaging
the packings by overtightening.
4. Apply one drop of adhesive, supplied, to the threads
of the piston valve. Then hand tighten the valve assembly into the piston rod just until the nut (411) contacts the rod. See Fig. 30.
A
B
NOTE: Note the alignment of the piston (422) to the nut
(411). Maintain this alignment through Steps 5, 6 and 7.
5. Place the flats at the top of the rod (424) in a vise.

Reassembly Notes
1. Pump Repair Kit, P/N 220–877, is available. For the
best results, use all the new parts in the kit, even if
the old ones still look good. Parts included in the kit
are shown with an asterisk, e.g., (410*) in the text
and drawings.
2. Check the outside of the piston rod (424) and the inside of the sleeve (418) for scoring or scratches. If
the parts are damaged, new packings will not seal
properly. Replace these parts if needed.

The Graco Warranty and Disclaimers
WARRANTY
Graco warrants all equipment manufactured by it and bearing its name to be free from defects in material and workmanship on
the date of sale by an authorized Graco distributor to the original purchaser for use. As purchaser’s sole remedy for breach of this
warranty, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment proven defective, with the exception of defects in parts on the drive train/gear box on EM and GM sprayers or power train on EH and GH
sprayers, which will be repaired or replaced for twenty-four months from the date of sale for Gas–Hydraulic (GH) and GasMechanical (GM) sprayers and for thirty-six months from the date of sale for Electric-Mechanical (EM), Electric-Hydraulic (EH),
390st and 490st sprayers. This warranty applies only when the equipment is installed, operated and maintained in accordance
with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for, any malfunction, damage or wear caused by faulty installation,
misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility with Graco
equipment of structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor
for verification of the claim. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any
defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts,
labor and transportation.
DISCLAIMERS AND LIMITATIONS
The terms of this warranty constitute purchaser’s sole and exclusive remedy and are in lieu of any other warranties (express or
implied), including warranty of merchantability or warranty of fitness for a particular purpose, and of any non–contractual
liabilities, including product liabilities, based on negligence or strict liability. Every form of liability for direct, special or consequential damages or loss is expressly excluded and denied. In no case shall Graco’s liability exceed the amount of the purchase price.
Any action for breach of warranty must be brought within two (2) years of the date of sale.
EQUIPMENT NOT COVERED BY GRACO WARRANTY
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose, with
respect to accessories, equipment, materials, or components sold but not manufactured by Graco. These items sold, but not
manufactured by Graco (such as electric motor, switches, hose, etc.) are subject to the warranty, if any, of their manufacturer.
Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.
