SKIN INJECTION
HAZARD
Liquids can be injected into the body by high pressure airless spray
or leaks – especially hose leaks.
Keep body clear of the nozzle. Never stop leaks with any part of the
body. Drain all pressure before removing parts.Avoid accidental triggering of gun by always setting safety latch when not spraying.
Never spray without a tip guard.
In case of accidental skin injection, seek immediate
“Surgical Treatment”.
Failure to follow this warning can result in amputation or serious
injury.
READ AND UNDERSTAND ALL LABELS AND INSTRUCTION MANUALS BEFORE USE
SAFETY 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 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 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 dif fuser operation
regularly. Follow the PRESSURE RELIEF PROCEDURE , below, then remove the spray tip. Aim the gun into a metal pail, holding the gun firmly to the pail. Using the lowest possible pressure,
trigger the gun. If the fluid emitted is not diffused into an irregular
stream, replace the 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 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 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 CAREFULL Y. 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 on page 3.
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

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.
¡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. 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
If you are supplying your own hoses and spray gun,
be sure the hoses are electrically conductive, that
the gun has a tip guard, and that each part is rated
for at least 2750 psi (190 bar) Maximum Working
Pressure. This is to reduce the risk of serious bodily
injury caused by static sparking, fluid injection or
over-pressurization and rupture of the hose or gun.
3. Check the electrical service
a. Be sure the electrical service is 120 V, 60 HzAC,
15 Amp (minimum), and that the outlet you use
is properly grounded.
CAUTION
To avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions.
4. Be sure your system is properly grounded before
operating it. Read and follow the warning section,
FIRE OR EXPLOSION HAZARD, on page 3.
1. Always use nylon spray hose at least 50 ft.
(15.2 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 filter and the main hose. See Fig 1.
4. Always use the main filter outlet for one gun operation. Never plug this outlet.
1. Connect the hose and gun (See Fig 1)
a. Remove the plastic cap plug from the filter outlet
nipple and screw a minimum 50 ft. (15.2 m) main
fluid hose onto the nipple.
b. For more flexible gun movement, connect a 3/16”
ID, 3 ft (0.9 m) hose between the main fluid hose
and the gun inlet adapter.
c.
DO NOT use thread sealant, and DO NOT install
the spray tip yet!
2. Fill the packing nut/wet–cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied. See Fig 1.
b. DO NOT remove the grounding prong of the plug,
and do not use an adapter.
c.
Use a grounded extension cord which has 3 wires
having a 12 gauge size, and a maximum length
of 100 ft (30 m). Longer lengths or smaller gauges
may affect sprayer performance.
5. Plug in the sprayer
a. Be sure the ON/OFF switch is OFF. See Fig 1.
b. Plug the power supply cord into a grounded electrical outlet that is at least 20 ft (6 m) aways from
the spray area to reduce the chance of a spark igniting the spray vapors.
c.
Do not remove the third prong of the power supply cord plug, which is the grounding prong, and
do not use an adapter.
6. Flush the pump to remove the lightweight oil which
was left in the pump to protect it from rust.
a. Before using water-base paint, flush with mineral
spirits, followed by a soapy water flush, and then
flush with clean water.
b. Before using oil-base paint, flush with mineral
spirits, only.
c.
See FLUSHING GUIDELINES, on page 12, for
the flushing procedure.
7. Prepare the paint according to the manufacturer ’s
recommendations.
a. Remove any skin that may have formed.
b. Stir the paint to mix pigments.
c.
Strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove particles that could clog the filter or spray tip. This is
probably the most important step toward troublefree spraying.

SHUTDOWN AND CARE
1. Check the packing nut/wet–cup daily. First relieve
pressure; see page 9. Be sure the wet–cup is 1/3 full
of TSL at all times to help prevent fluid buildup on the
piston rod and premature wear of packings. The
packing nut should be tight enough to stop leakage,
but no tighter. Overtightening may cause binding and
excessive packing wear. See Fig 6.
2. Clean the fluid filter often and before storing the
sprayer. First relieve pressure; see page 9. See manual 307–273, supplied, for the filter cleaning procedure.
3. 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.
4. For very short shutoff periods, leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
5. Coil the hose and hang it on the hose rack when storing it, even for overnight, to help protect the hose from
kinking, abrasion, coupling damage, etc.
6. For the low–profile cart, use the brackets on the
side of the cart to hold the suction assembly.
WARNING
Refer to the warning section HOSE SAFETY on
page 3 for information on the hazard of using damaged hoses.
CAUTION
Never leave water or any paint in the sprayer overnight to: (1) prevent pump corrosion; (2) 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.
PACKING NUT/WETCUP

FLUSHING GUIDELINES
NOTE: The Pressure Relief Procedure Warning is on
page 14.
When To Flush
CAUTION
NEVER leave water in the sprayer if there is the
slightest change 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. The sprayer was factory tested in lightweight oil,which was left in to protect the pump parts.
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, then 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.
Water-base paint: Flush with water, and then mineral spirits. Leave the pump, hose and gun filled with
mineral spirits. Shut of f the sprayer and open the
pressure drain valve to relieve pressure.
Oil-base paint: Flush with mineral spirits. Shut of f
and unplug the sprayer, open the pressure drain valve
to relieve pressure.
6. Startup after storage.
Before using water-base paint, flush out the mineral spirits with soapy water, and then with clean water.
When using oil-based paint , flush out the mineral
spirits with the paint to be sprayed.
How To Flush
1. Relieve pressure.
2. Remove the filter bowl and screen; see instruction
manual 307–273, supplied. Clean the screen separately and install the bowl, without the screen, to flush
the bowl. See Fig 7.
3. Close the pressure drain valve.
4. Pour one–half gallon (2 liters) of compatible solvent
into a grounded metal pail. Put the suction tube in the
pail.
5. Remove the spray tip from the gun.
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, and aimed into, a grounded metal pail
6. Disengage the gun safety latch. Point the gun into a
metal waste container . With metal part of the gun
firmly touching the metal container, squeeze the gun
trigger. See Fig 8. This procedure reduces the risk of
static sparking and splashing. 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.
7. Check all fluid connections for leaks. If any connections leak, first relieve pressure. Tighten the connections. Start the sprayer. Recheck the connections for
leaks.
8. 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.
9. Leave the pressure drain valve open until you are
ready to use the sprayer again. Unscrew the filter
bowl and reinstall the clean screen. Reinstall the
bowl, hand tight only.
10. 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
Always hold the gun perpendicular to the work surface
and at an even12 to 14 in. (300–356 mm) from the surface
you are spraying. See Fig 9.
Begin moving the gun in a horizontal direction 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 work
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! Using the lowest pressure necessary to get the
desired paint atomization will help prolong the life of your
sprayer and minimize 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 11.
CORRECT
Fig 9
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 alternately from right to
left and then left to right to get a professional finish.
See Fig 10.
Fig 11
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 canvas dropcloth as the painter approaches
the area. Remove the dropcloth as soon as the area is
painted to prevent damage to the shrubs.
Concrete walks. If the walkways will be walked on, cover
them with a canvas dropcloth to avoid slipping. Otherwise
a plastic dropcloth can be used.
Electrical outlets and lamps. Protect electrical outlets
with masking tape. Cover lamps with plastic bags secured
with masking tape.
Fig 10
Nearby objects. Move portable upwind of the surface to
be sprayed. If there is a nearby home, make a protective
barrier by hanging plastic between two long poles.

Be sure to order the correct circuit board. See the
application information on page 24.
11. Adjust the pressure control. See page 22.
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,
to be sure the sprayer is properly calibrated.
Improper adjustment 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.
Service Tools Needed:
NEW 50 foot (15.2 m), 3000 psi (207 bar). flexible nylon, airless spray hose, Part No. 223–541
0–5000 psi (0–350 bar) fluid–filled pressure gauge,
Part No. 102–814
Needle valve, Part No. 102–715 or 103–067
3/8 in. socket wrench
5 gallon pail and water
Mineral spirits
NEVER attempt to increase the fluid outlet pressure
by performing these adjustments in any other way.
Normal operation of the sprayer at higher pressures
could 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.
1. Follow the Pressure Relief Procedure Warning on
page 14.
2. Connect the new 50 ft (15.2 m) spray hose to
the
sprayer outlet. Install the needle valve on the other
end of the hose. Install the fluid–filled pressure gauge
in the top port of the fluid filter.
3. Remove the pressure control cover (41) and the plug
(135) (see the parts drawings) from the bottom of the
pressure control. In Step 6, you will insert the 3/8 in.
socket wrench through the plug hole (C) to engage
the pressure adjustment nut (B) which is located on
the bottom of the pressure control knob shaft.
PRESSURE CONTROL ADJUSTMENT
ON/OFF SWITCH
A
If the pressure is lower than 2750 psi (190 bar):
Unplug the sprayer . Relieve pressure. Insert the
wrench and untighten the pressure adjustment nut
1/8 turn or less, then repeat steps 5 and 6.
If the pressure is higher than 2750 psi (190 bar):
Unplug the sprayer . Relieve pressure. Insert the
wrench and tighten the pressure adjustment nut 1/8
turn or less and 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.
B
D
Fig 22
TIGHTEN
C
4. Open the needle valve slightly. Turn the pressure control knob (A) to the minimum setting.
5. Plug in the sprayer and turn the switch ON. Increase
the pressure setting just enough to start the sprayer.
Prime the hose, being sure to eliminate all air from the
system.
6. Open the needle valve a little more––enough to allow
the pump to run continuously––and turn the pressure
control knob to maximum. Now , very slowly start to
close the needle valve, but don’t close it all the way.
Observe the pressure at which the pump stalls, which
should be approximately 2750 psi (190 bar).
NOTE: 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.
8. Open the needle valve very slowly while observing
the pressure gauge. Check to see if the pressure
drops to approximately 2350 psi (164 bar) before
starting again.
If the pressure is not 2350 psi (164 bar):
Shut off and unplug the sprayer , but do not relieve
pressure. T urn the dif ferential 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 dif ferential wheel, recheck the
stall pressure (steps 5 and 6) to be sure the stall
pressure has not changed.
9. Follow the Pressure Relief Procedure Warning on
page 14. Flush the water out with mineral spirits. Relieve pressure again. Install the plug (135) and the
pressure control cover (41). Remove the test hose,
needle valve and pressure gauge.
