WARNING
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 bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes can cause serious
damage.
NEVER point the spray gun at anyone or at any part of the
body. NEVER put hand or fingers over the spray tip. NEVER
try to “blow back” paint; this is NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
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 Treatment
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. For treatment
instructions, have your doctor call the
NATIONAL POISON CENTER NETWORK
(412)681-6669
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 injec-
tion 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 in-
to 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 injection hazard and
helps prevent accidentally placing your fingers or any part of
your body close to the spray tip.
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 and then remove the spray tip to clean it.
NEVER wipe off build-up around the spray tip until pressure is
fully relieved and the gun safety latch is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including injection 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, clean-
ing 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. (5) Hold a metal part of the gun firmly to the side of
a metal pail, and trigger the gun to relieve pressure. (6) Engage the gun safety latch. (7) Open the drain valve, having a container
ready to catch the drainage. (8) Leave the drain 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 and relieve pressure gradually, then loosen
completely. Now clear the tip or hose.

EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and materials, or using worn or damaged parts, can
cause them to rupture and result in injection or other serious
bodily injury, 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.
System Pressure
This sprayer can develop 2500 psi (172 bar) MAXIMUM
WORKING PRESSURE. Be sure that all spray equipment and
accessories are rated to withstand the maximum working
pressure of this sprayer. DO NOT exceed the maximum work-
ing pressure of any component or accessory used in the
system.
Material Compatibility
BE SURE that all materials and solvents used are chemically
compatible with the wetted parts shown in the Technical Data
on the back cover. Always read the material and solvent
manufacturer's literature before using them in this sprayer.
HOSE SAFETY:
High pressure fluid in the hoses can be very dangerous. If the
hose develops a pinhole leak, split or rupture due to any kind
of wear, damage or misuse, the high pressure spray emitted
from it can cause an injection injury or other serious bodily in-
jury or property damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS! The
spring guards help protect the hose from kinks or bends at or
close to the coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check 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. Do not use materials or solvents
which are not compatible with the inner tube and cover of the
hose. DO NOT expose the hose to temperatures above 180°F
(82°C) or below -40°F (-40°C).
Hose Grounding Continuity
The fluid hoses provided with this sprayer have electrically
conductive material on the surface of the center core of the
hose. Other hoses on the market may have a ground wire ex-
tending the length of the hose. The ground wire can break in
use which will destroy the electrical grounding of the hose.
To be sure of continuity, check electrical resistance at least
once a week. Check overall resistance when using multiple
hose assemblies. If the resistance exceeds 29 megohms,
replace it immediately. Ground wire hose may have different
resistance; check supplier.
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equip-
ment 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. 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 ex-
plosion 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.
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 in-
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1. prayer: 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 ex-
tension cords must have three wires and be rated for 15
amps.
2. Fluid hoses: use only grounded hoses with a maximum of
500 feet (150 m) combined hose length to ensure ground-
ing continuity. Refer to Hose Grounding Continuity.
3. Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer.
4. Object being sprayed: according to local code.
5. 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.
6. To maintain grounding continuity when flushing or reliev-
ing pressure, always hold a metal part of the gun firmly to
the side of a metal pail, then trigger the gun.
Flushing Safety
Reduce the risk of injection injury, static sparking, or splashing
by following the specific 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 metal pail and use the
lowest possible fluid pressure during flushing.
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. Unplug the sprayer and relieve pressure
before checking or servicing the sprayer to prevent it from
starting accidentally.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards — par-
ticularly the General Standards, Part 1910, and the Construction Standards, Part 1926— should be consulted.

RISQUES EN CAS DE MAUVAISE UTILISATION DU MATERIEL:
Consignes générales de sécurité
Toute utilisation anormale de l’appareil de 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 abimées 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.
NE JAMAIS altérer ou modifier une pièce de cet appareil: ceci
risquerait d'entraîner son mauvais fonctionnement.
VERIFIER régulièrement tout l'appareil de pulvérisation et ses
équipements et réparer ou remplacer immédiatement les
pièces usées ou abîmées.
MESURES DE SECURITE CONCERNANT LES TUYAUX FLEXIBLES
Le fluide à haute pression circulant dans les tuyaux peut être
très dangereux. En cas de fuite sur le tuyau, même minuscule,
de fissure, déchirure ou rupture a la suite de I"'usure, de dégats
ou d'une mauvaise utilisation, les projections de fluide haute
pression qui en proviennent peuvent entrainer des blessures
graves par penétration sous la peau ou par contact, ainsi que
des dégâts matériels.
TOUS LES TUYAUX FLEXIBLES DOIVENT AVOIR DES
RESSORTS SPIRALE DE PROTECTION! 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 voisinagé.
SERRER FERMEMENT tous les raccords avant chaque utilisa-
tion. 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. Avant chaque
utilisation, vérifier entièrement chaque tuyau pour déceler les
coupures, fuites, abrasions, boursouflures de l'enveloppe ou
toute autre détérioration ou jeu des raccords. Si l’on constate
l'une de ces détériorations, il faut remplacer le tuyau im-
médiatement. NE PAS essayer de refaire le raccord d’un tuyau
haute pression ni de réparer le tuyau avec du ruban adhésif ou
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 convenable-
ment reliées à la masse ou à la terre, des étincelles peuvent se
produire et l'appareil risque d’être dangereux. Des étincelles
peuvent également se produire à l’occasion du branchement
ou du débranchement du cordon d'alimentation. 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 pulvérise à l’in-
térieur 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 des vapeurs
encore présentes dans l’aïr prennent feu.
Mise à la terre ou à la masse
Pour réduire les risques de production d’étincelles d'électricité
statique, le pulvérisateur et tous les équipements utilisés ou se
trouvant dans la zone de pulvérisation doivent étre reliés 4 la
terre ou a la masse. Pour connaitre le détail des instructions de
mise á la terre dans la région et le type particulier d'équipe-
ment, CONSULTER le code ou les réglementations électriques
locales. S'ASSURER que tous les équipements de pulvérisa-
tion suivants sont bien reliés 4 la terre:
1. Pulvérisateur: Brancher le cordon d'alimentation ou la
rallonge qui doivent étre équipés d'une prise a 3 fiches en bon
état, dans une prise de courant convenablement mise à la
terre. Ne pas utiliser d’adaptateur. Toutes les rallonges doivent
avoir 3 fils et étre prévues pour 15 ampères.
Pression
Ce pulvérisateur peut produire une PRESSION MAXIMUM DE
TRAVAIL 172 bar (2500 Ib/po.2). S'assurer que tous les
éléments du pulvérisateur et ses accessoires sont concus 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.
Compatibilité chimique des corps
BIEN S'ASSURER que tous les corps des solvants utilisés
sont chimiquement compatibles avec les parties mouillées in-
diquées dans les “Données techniques”, au dos de la couver-
ture. Toujours lire soigneusement les documents et brochures
du fabricant des matiéres et solvants utilisés avant de s'en ser-
vir dans ce pulvérisateur.
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 matériel en tirant sur le tuyau. Ne pas utiliser de matiéres ou
de solvants qui ne sont pas compatibles avec l'enveloppe in-
térieure ou extérieure du tuyau. NE PAS exposer le tuyau à
des températures supérieures à 82°C (180°F) ou inférieures à
-40°C (-40°F).
Continuité du circuit de mise à la terre des tuyaux
Les tuyaux flexibles fournis avec ce pulvérisateur ont une sur-
face conductrice continue au cœur du tuyau. D'autres tuyaux
vendus dans le commerce comportent un fil de mise à la terre
allant tout au long du tuyau. Ce fil de mise à la terre peut se
rompre à l'usage, ce qui supprime la mise à la terre du tuyau.
Pour être certain de la continuité de la mise à la terre, il faut
vérifier la résistance électrique des tuyaux au moins une fois
par semaine. Vérifier aussi la résistance d'ensemble quand il у
a plusieurs tuyaux assemblés. Si la résistance dépasse 29
mégohms, remplacer immédiatement le tuyau. La résistance
des tuyaux mis à la terre par un fil peut être différente: se
renseigner auprès du fournisseur.
2. 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 ‘’Con-
tinuité du circuit de mise a la terre des tuyaux”.
3. Pistolet: Réaliser la mise à la terre en le raccordant à un
tuyau flexible et à un pulvérisateur déjà convenablement reliés
à la terre.
4. Objets, matériel ou surfaces recevant la pulvérisation:
observer le code ou les réglementations locales.
5. Jous les seaux de solvants utilisés pour le rincage: observer
le code ou les réglementations locales. W utiliser que des seaux
métalliques conducteurs de l'électricite. Ne pas mettre le seau
sur une surface non conductrice comme sur du papier ou du
carton car cela interromprait la continuité le la mise à la terre.
6. Pour conserver la continuité de la mise 4 la terre quand on
rince 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.
Mesures de Sécurité concernant le Rincage
Pour réduire les risques de blessures par pénétration de la
peau et les risques dûs aux étincelles d'électricité statique ou
aux éclaboussures, observer la marche à suivre pour le rincage
donnée à la page 12 de ce manuel. Observer la “Marche a
Suivre pour Détendre la Pression” donnée 2 la page 4 en
enlever l'ajutage du pulvérisateur avant le rincage. Maintenir
une partie métallique du pistolet fermement appuyée contre le
côté d'un seau en métal et utiliser la pression la plus faible
possible pendant le rincage.

tos 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 alta presión puede desalojar un acoplamiento suelto
o dejar que por 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 en-
contrarse cualquiera de estas condiciones, reemplazar de in-
mediato 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 a alta presión.
MANEJAR Y PASAR CUIDADOSAMENTE LAS
MANGUERAS. No tirar de las mangueras para mover el
equipo. No usar materiales o solventes que sean incompatibles
con el tubo interno y la cubierta dela manguera. NO exponer
las mangueras a temperaturas sobre 82%C (180°F) o bajo
-40°C {-40°F).
Continuidad a tierra de la manguera
Las mangueras para fluidos provistas con esta pulverizadora
tienen material eléctricamente conductivo en la superficie del
nucleo central. Otras mangueras a la venta tienen a veces un
alambre a tierra a todo el largo. Este alambre puede romperse
con el uso, destruyéndose por lo tanto, la conexión a tierra de
la manguera.
Como precaución, revisar por lo menos una vez a la semana la
resistencia eléctrica. Revisar la resistencia general al usar con-
juntos de mangueras múltiples. Si excede de 29 megaohmios,
reemplazarla de inmediato. Las mangueras con alambre a
tierra tienen diferentes resistencias; consultar con el
proveedor.
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, convirtiendo al sistema en algo peligroso. También,
pueden producirse chispas al enchufar o desenchufar el cor-
dón eléctrico. 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 pulverizadora 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.
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 exten-
sor, 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. Objeto que se está rociando: de conformidad con el código
local.
5. Todos los baldes de solvente usados durante el lavado, de
conformidad con el código local. Usar so/amente baldes de
metal, que sean conductivos. No colocar el balde en una
superficie no conductiva, como papel o cartón, que inter-
rumpe la continuidad a tierra.
6. 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 del balde de metal,
después apretar el gatillo.
Seguridad durante el lavado
Reducir el riesgo de lesiones por inyección, chispas eléctricas
o salpicaduras, siguiendo el procedimiento de lavado
específico dado en la página 12 de este manual. Seguir el pro-
cedimiento de descarga de presión en la página 6, y quitar
la boquilla rociadora antes de lavar. Apoyar una parte metálica
de la pistola bien firme contra el costado de un ba/de de metal
y usar la presión más baja posible de fluido durante el lavado.
PELIGRO DE LAS PIEZAS MOVILES :
Las piezas en movimiento pueden pinchar o amputar dedos u
otras partes del cuerpo. MANTENERSE ALEJADO de las
piezas en movimiento durante el arranque o funcionamiento
de la pulverizadora. Desenchufar la pulverizadora y descargar
la presión antes de revisarla o darle servicio, para impedir que
arranque inesperadamente.
IMPORTANT
Se han adoptado las normas de seguridad del gobierno de los
Estados Unidos de Norteamérica bajo el Acta de Seguridad y
Salud Ocupacional. Deberán consultarse estas normas, en
especial las Generales, Parte 1910, y las Normas de Construc-
ción, Parte 1926.

1. Connect Hose and Gun (Refer to Fig 1.)
a. Remove the plastic cap plug from the filter
outlet nipple and screw the 50 ft (15.2 m) fluid
hose onto the nipple.
b. Connect the whip hose between the fluid hose
and the gun inlet connection.
c. Don’t use thread sealant, and don’t install the
spray tip yet!
CAUTION
To avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions:
1. Always use nylon spray hose of at least
50 ft (15.2 m) long.
2. Never use a wire braid hose as 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 2.
4. Always use the main filter outlet. Never
plug this outlet,
2. Fill Packing Nut/Wet-Cup (See Fig 2.)
Fill the packing nut/wet-cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied.
3. Check 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.
b. Use an extension cord which has 3 wires of a
minimum 12 gauge size, and a maximum of
50 ft (15 m) long. Longer lengths may affect
sprayer performance.
4. Plug in the Sprayer
a. Be sure the ON/OFF switch is OFF. Refer to
Fig 3.
b. Plug the power supply cord into a grounded
electrical outlet that is at least 20 ft (6 m) away
from the spray area to reduce the chance of 3
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.
5. Flush the pump to remove the No. 10 motor oil
which was left in to protect pump parts after fac-
tory testing. See “Flushing Guidelines” on page 12
for flushing procedure.
6. Prepare the paint according to the manufacturer's
recommendations.
a. Remove any skin that may have formed.
b. Stir the paint to dissolve pigments.
c. Strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove par-
ticles that could clog the filter or spray tip. This
is probably the most important step toward
trouble-free spray painting.

4. Cleaning a Clogged Tip
WARNING
To reduce the risk of serious bodily injury from in-
jection, use extreme caution when cleaning or
changing spray tips. If the spray tip clogs while
spraying, engage the gun safety latch immediate-
Y then follow the procedure in Steps da-4e,
elow.
NEVER wipe off build up around the spray tip until
pressure is fully relieved and the gun safety latch is
engaged.
a. Clean the front of the tip frequently during the
day's operation. First, follow the Pressure
Relief Procedure Warning in on page 10. Then
use a solvent-soaked brush to keep material
from building up and clogging the tip.
b. If the spray tip does clog, release the gun trig-
ger, engage the gun safety, and rotate the
spray tip handle 180°. See Fig 7.
c. Disengage the gun safety and trigger the gun
into a waste container. Engage the gun safety
again.
d. Return the handle to the original position,
disengage the gun safety, and resume spray-
Ing.
e. If the tip is still clogged, engage the gun safety,
shutoff and unplug the sprayer, and open the
drain valve to relieve pressure. Clean the spray
tip as instructed in “Service” in instruction
manual 307-321, supplied.
SHUTDOWN AND CARE
1. Check the packing nut/wet-cup daily. First
follow the Pressure Relief Procedure Warning on
page 10. Be sure the wet-cup is 1/3 full of TSL at
all times to help prevent material build up 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. Use a screw-
driver and light hammer to adjust the nut. See
Fig 8.
2. Clean the fluid filter often and whenever the
sprayer is stored. First follow the Pressure Relief
Procedure Warning on page 10. Refer to manual
307-273, supplied, for the 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.
CAUTION
7 |
Never leave water or any paint in the sprayer over-
night to: (1) prevent pump corrosion; (2) prevent
the material 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.

triggered, turn the ON/OFF switch to ON and slow-
ly turn the pressure adjusting knob clockwise just
until the sprayer starts. Keep the gun triggered until
clean solvent comes from the nozzle. Release the
trigger and engage the gun safety latch.
Check all fluid connections for leaks. If any leak,
first follow the Pressure Relief Procedure Warning
on page 10. Then tighten the connections, start the
sprayer, and recheck the connections for leaks.
Remove the suction tube from the pail. Disengage
the gun safety and trigger the gun to force solvent
from the hose. Do not let the pump run dry for
more than 30 seconds to avoid damaging the
pump packings! Then turn ON/OFF switch to OFF
and engage the gun saftey.
Unplug the power supply cord. Open the drain
valve and leave open until you are ready to use the
sprayer again. Unscrew the filter bowl and reinstall
the clean screen. Be sure the screen and support
are installed as shown in Fig 9.
. If you have flushed with mineral spirits and are go-
ing to use a water-base paint, flush with soapy
water followed by a clean water flush. Then repeat
Step 1.
Application Methods
Always hold the gun perpendicular to the surface and
keep the gun at an even 12 to 14 in. (300-356 mm) from
the surface you are spraying. See Fig 11.
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, release the trigger. This method avoids excess
paint build-up at the end of each stroke.
RIGHT
WRONG
Fig 11
The correct speed for moving the gun will allow a full,
wet coating to be applied without runs or sags. Lapping
each stroke about 50% over the previous stroke pro-
duces uniform paint thickness. And spraying in a
uniform pattern alternately from right to left, then left to
right, provides a professional finish. See Fig 12.
The best way to control the rate of coverage is with the
gun tip size. A small tip orifice applies less paint and a
narrower pattern. A larger tip orifice applies more paint
and a wider pattern.
Do not try to increase coverage by increasing the fluid
pressure! Using the lowest pressure necessary to get
the results you want will help prolong the life of your
Sprayer and minimize paint lost by overspray.
For interior corners, such as on a bookcase or inside a
cabinet, aim the gun toward the center of the corner to
spray. By dividing the Spray pattern this way, the edges
on both sides are sprayed evenly. See Fig 13.
Fig 13
If there is a wind, angle the spray pattern into the wind
to minimize drifting. Paint from the ground to the roof.
Shrubs. When next to the house, tie back shrubs from
the surface to be painted with rope and stakes. Then
cover them with a canvas dropcloth as the painter ap-
proaches the area. Remove the canvas dropcloth as
soon as the area is painted, to prevent possible 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 cloth is all that is needed.
Electrical outlets and lamps. Protect electrical outlets
with masking tape. Cover lamps with plastic bags
secured with masking tape.
Nearby objects. Move objects such as automobiles, pic-
nic tables, lawn furniture, etc. up-wind of the surface to
be sprayed. In the case of a nearby home, make a pro-
tective barrier by hanging plastic between two long
poles.

WARNING
USE EXTREME CAUTION WHEN PERFORMING THIS CALIBRATION PROCEDURE to reduce the risk of
an injection injury or other serious bodily injury which can result from component rupture, electric shock, fire, ex-
plosion, or moving parts.
This procedure sets the sprayer to 2500 psi (172 bar)
MAXIMUM WORKING PRESSURE.
This procedure must be performed whenever a new
or used circuit board, microswitch, or pressure con-
trol 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 ob-
taining the maximum working pressure which would
result in poor sprayer performance.
NEVER attempt to increase the fluid outlet pressure
by performing these calibrations in any other way.
NEVER EXCEED 2500 psi (172 bar) MAXIMUM
WORKING PRESSURE. Normal operation of the
sprayer at higher pressures could result in compo-
nent rupture, fire or explosion.
ALWAYS use a new 50 foot (15.2 m) spray hose
rated for 3000 psi (210 bar) MAXIMUM WORKING
PRESSURE when performing this procedure. A us-
ed, under-rated hose could develop a high pressure
leak or rupture.
AVOID touching the wire in the pressure control
assembly when the control box cover is removed to
reduce the risk of electric shock.

Tools Needed:
NEW 50 ft (15.2 m) 3000 psi (210 bar) airless spray

NOTE:

Follow the Pressure Relief Procedure Warning on
page 12. Install the new 50 ft (15.2 m) spray hose
to the sprayer outlet. On the other end of the hose
install the needle valve. Install the fluid-filled
pressure gauge in the top port of the fluid filter.
Open the needle valve slightly. Turn the pressure |
control knob (D) to the minimum setting. 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.
Open the needle valve a little more—enough to
allow the pump to run continously —and turn the
pressure control knob to maximum. Now, very
slowly start to close the needle valve, but dont
close it all the way. Observa the pressure at which
the pump stalls, which should be approximately
2500 psi (172 bar).
The slower the pressure is brought up, 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.
If the pressure is lower: unplug the sprayer and
relieve pressure. Use a 3/8" open end wrench to
turn the pressure adjustment nut, at the bottom of
the pressure control knob shaft (R), counterclock-
wise 1/8 turn or less, then repeat steps 2 and 3.
If the pressure is higher: unplug the sprayer and
relieve pressure. Turn the pressure adjustment nut
clockwise 1/8 turn or less and repeat steps 2 and 3.
Repeat until the proper stall pressure is obtained.
307-371
NOTE:
Now check to see at what pressure the sprayer
starts to run again after stalling. 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.
Now open the needle valve very slowly while ob-
serving the pressure gauge. Check to see if the
pressure drops to approximately 2100 psi (147 bar)
before starting again.
If the pressure is lower: shut off and unplug the
sprayer, but do not relieve pressure. Turn the dif-
ferential wheel (F) counterclockwise just one notch
and repeat Steps 4 and 5. Check the pressure drop
again, and repeat if necessary.
If you adjust the differential wheel, recheck
the stall pressure (steps 2 and 3) to be sure
the stall pressure has not changed.
Follow the Pressure Relief Procedure on page 14,
flush the water out with mineral spirits, relieve
pressure again, then remove the test hose, needle
valve and pressure gauge.
