WARNINGS

HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.

FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.

Read and understand all instruction manuals before operating the equipment.

FLUID INJECTION HAZARD

General Safety

This equipment generates very high fluid pressure. Spray from the gun, leaks or ruptured components can inject fluid through your skin and into your body, and cause extremely serious bodily injury, including the need for amputation. Also, fluid injected or splashed into the eyes or on the skin can cause serious damage.

NEVER point the spray gun at any one or at any part of the body. NEVER put your hand or fingers over the spray tip.

NEVER try to “blow back” paint; this is NOT an air spray system.

ALWAYS have the tip guard in place on the spray gun when spraying.

ALWAYS follow the PRESSURE RELIEF PROCEDURE, below, before cleaning or removing the spray tip or servicing any system equipment.

NEVER try to stop or deflect leaks with your hand or body.

Be sure equipment safety devices are operating properly before each use.

Medical Alert––Airless Spray 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.

Spray Gun Safety Devices

Be sure all gun safety devices are operating properly before each use. Do not remove or modify any part of the gun; this can cause a malfunction and result in serious bodily injury.

Safety Latch

Whenever you stop spraying, even for a moment, always set the gun safety latch in the closed or “safe” position, making the gun inoperative. Failure to set the safety latch can result in accidental triggering of the gun.

Diffuser

The gun diffuser breaks up spray and reduces the risk of fluid injection when the tip is not installed. Check 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 gun safety latch immediately. ALWAYS follow the PRESSURE RELIEF PRO-

CEDURE, below, and then remove the spray tip to clean it.

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.

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

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.

HOSE SAFETY

High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or rupture due to any kind of wear, damage or misuse, the high pressure spray emitted from it can cause a fluid injection injury or other serious bodily injury or 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 there is 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

13 of this manual. Follow the PRESSURE RELIEF PROCE-

DURE 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.

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.

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 CHOI-

SIR 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 pistolet.

SOLO PARA USO PROFESIONAL. RESPECTE LOS AVISOS DE ADVERTENCIA.

Lea y entienda todo el manual de instrucciones 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 INMEDIATO.

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 quirúrgi- camente la lesión a la brevedad posible. No demorar el tra tamiento 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.

1. Enganchar el pestillo de seguridad de la pistola.

2. Mover el interruptor de parada del motor a OFF.

3. Desenchufar el cordón eléctrico.

4. Desenganchar el pestillo de seguridad de la pistola. Mantener una parte metálica de la pistola firmemente contra el lado de un balde de metal y activar la pistola para descargar la presión.

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.

5. Volver a enganchar el pestillo de seguridad de la pistola.

6. Abrir la válvula de alivio de presión y dejarla abierta hasta que se esté nuevamente listo para pulverizar.

Si se sospecha que la boquilla o la manguera esté completamente obstruida, o que no se ha descargado por completo la presión después de haber seguido el procedimiento anterior , aflojar MUY LENTAMENTE un adaptador de extremo de la manguera o la tuerca de renención del protector de lay punta y descargar gradualmente la presión.

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.

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.

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:

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 en la página

31.

MANEJAR Y PASAR CUIDADOSAMENTE LAS MANGUE-

RAS. 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.

EXPLOSION, más arriba.

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 mangue- ra.

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 13. 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.

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. Ground the sprayer and all objects being sprayed. Read FIRE OR EXPLOSION

HAZARD on page 3.

2. Do not operate the spray gun without a tip guard in place.

3. Be sure all parts added to the sprayer are rated for at least 2750 psi (190 bar)

Maximum Working Pressure.

SETUP

CAUTION

To avoid damaging the pressure control, follow these precautions.

1. Always use flexible, grounded hose at least 50 feet (15 m) long.

2. Never use a wire braid hose; it is too rigid to act as a pulsation dampener.

3. Never install any shutoff device between the fluid filter and the first 50 feet (15 m) of hose. See Fig 1.

1. Connect a 50 foot (15 m) 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 200 feet (61 m) of 3 wire, 12 gauge (minimum) can be used.

Longer lengths will affect sprayer performance. Use more spray hose to reach the spray area, if needed.

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.

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.

MAINTENANCE

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.

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.

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.

3. For very short shutoff periods, leave the suction tube in the paint, relieve pressure, unplug the sprayer, and clean the spray tip.

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.

5. Secure the suction hose to the brackets on the side of the cart.

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.

3. Changing from water-base to oil-base

paint. Flush with warm, soapy water, and then flush with mineral spirits.

4. Changing from oil-base to water-base

paint. Flush with mineral spirits, followed by warm, soapy water, and then a clean water flush.

5. Storage. Flush, leave the pump, hose and gun filled with mineral spirits. Shut off the sprayer and open the pressure drain valve to relieve pressure.

Water-base paint: Flush with water, and then mineral spirits.

Oil-base paint: Flush with mineral spirits.

6. Startup after storage.

Before using water-base paint, flush with soapy water, and then with clean water.

When using oil-based paint, with the paint to be sprayed.

How to flush

1. Relieve pressure. See page 9.

2. Remove the filter bowl and screen: see manual 307–273. Install the bowl (only) to flush it.

Close the pressure drain valve. See Fig 6.

3. Pour one–half gallon (2 liters) of compatible solvent into a grounded metal pail. Put the suction tube in the pail.

4. Remove the spray tip.

WARNING

To reduce the risk of static sparking and splashing when flushing, always remove the spray tip from the gun, and hold a metal part of the gun firmly to the side of a grounded metal pail. See Fig 7.

5. Disengage the gun safety latch. Start the sprayer, trigger the gun, and slowly turn the pressure adjusting knob clockwise just until the pump starts. Keep the gun triggered until clean solvent comes from the nozzle. Release the trigger and engage the gun safety latch.

6. Check all fluid connections for leaks. Relieve pressure before tightening the connections.

Start the sprayer.

7. Remove the suction tube from the pail. Disengage the gun safety latch. Trigger the gun to force solvent from the hose. Do not run the pump dry for more than 30 seconds to avoid damaging the pump packings! Relieve pressure.

8. Remove the suction tube from the sprayer and clean it separately. Flushing alone will not clean it sufficiently.

9. Clean the filter screen and reinstall it in the bowl. See Fig 6.

10. Leave the pressure drain valve open until you use the sprayer again.

11. If you flushed with mineral spirits and are going to use a water-base paint, flush with soapy water followed by a clean water flush. Relieve pressure.

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 10 0673

Fig 8

WRONG

0072

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.

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.

OVERLAP EACH STROKE 50%

Fig 9 0672

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.

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.

10. Mount the pressure control on the cart. Connect the drain hose (41).

11.

Adjust the pressure control. See page 19.

WARNING

Adjust the pressure control whenever a new or used pressure control or circuit board is installed to reduce the risk of overpressurization which can result in component rupture, fire or explosion. Improper adjustment may also prevent the sprayer from obtaining the maximum working pressure, resulting in poor sprayer performance.

PRESSURE CONTROL ADJUSTMENT

WARNING

USE EXTREME CAUTION WHEN PERFORMING THIS ADJUSTMENT PROCEDURE to reduce the risk of a fluid injection injury or other serious bodily injury, which can result from component rupture, electric shock, fire, explosion or moving parts.

This procedure sets the sprayer to 2750 psi

(190 bar) MAXIMUM WORKING PRESSURE.

Perform this procedure whenever the microswitch or pressure control assembly is reinstalled or replaced.

Improper calibration can cause the sprayer to overpressurize, resulting 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 sprayer’s maximum working pressure by performing these adjustments in any other way. Normal operation of the sprayer at higher pressures may result in component rupture, fire or explosion. To perform this adjustment, however, the sprayer pressure must be temporarily increased above the normal working pressure.

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.

Service Tools Needed:

D

NEW 50 foot, 3000 psi (minimum) grounded, flexible airless spray hose, p/n 223–541

D

0–5000 psi fluid–filled pressure gauge,

1/4 npt, p/n 102–814

D

Needle valve, p/n 102–715 or 103–067

D

3/8 in. open end wrench

D

Mineral spirits

D

5 gallon pail and water

Procedure

1. Relieve pressure. See page 14.

2. Remove the old spray hose. Install the new hardware and hose as shown in Fig 17. On the other end of the hose install the needle valve.

NOTE: Refer to Fig 18 for the remainder of this procedure.

3. Remove the plug (311). See Fig 18.

4. Open the needle valve slightly. Turn the pressure adjusting knob (A) to the minimum setting.

5. Plug in the sprayer and turn the switch ON.

Increase the pressure just enough to start the sprayer. Fully prime the hose, being sure to eliminate all air from the system.

NOTE: In Step 6, 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.

6. Open the needle valve a just enough to allow the pump to run continuously, and turn the pressure adjusting 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. Insert the wrench through the hole (C) and loosen the adjustment nut (B) 1/8 turn or less. Repeat steps 5 and 6.

If the pressure is higher than 2750 psi (190 bar):

Unplug the sprayer and relieve pressure. Insert the wrench through the hole (C) and tighten the pressure adjustment nut (B) 1/8 turn or less. Repeat steps 5 and 6. Repeat this procedure until the proper stall pressure is obtained.

7. Now check to see at what pressure the sprayer starts to run again after it stalls. 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.

8. 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 the sprayer starts again.

If the pressure is not 2300 psi (161 bar):

Shut off and unplug the sprayer, but do not relieve pressure. Turn the differential wheel

(D) just one notch and repeat Steps 5 and 6.

Check the pressure drop again, and repeat if necessary.

NOTE: If you adjust the differential wheel, recheck the stall pressure (steps 5 and 6) to be sure the it has not changed.

9. Relieve pressure. Flush the water out with mineral spirits. Relieve pressure. Install the plug (311). Remove the test equipment.
