WARNINGS
High Pressure Spray Can Cause Serious Injury . For Professional Use Only.
Observe All W arnings. Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can inject fluid through
your skin and into your body, and cause extremely serious
injury, including the need for amputation. Also, fluid injected or
splashed into the eyes or on the skin can cause serious dam-
age.
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, be-
low, 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 W ounds
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE
CUT.
T ell 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 . T oxicity is a concern
with some exotic coatings injected directly into the blood
stream. Consultation with a plastic surgeon or reconstructive
hand
surgeon may be advisable.
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly before
each
use. Do not remove or modify any part of the gun; this can
cause a malfunction and result in serious injury .
Safety Latch
Whenever you stop spraying, even for a moment, always set
the gun trigger safety in the closed or “safe” position, making the
gun inoperative. Failure to set the safety latch can result in acci -
dental 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 , be -
low, then remove the spray tip. Aim the gun into a metal pail,
holding
the gun firmly to the pail. Using the lowest possible pres -
sure, trigger the gun. If the fluid emitted
is not diffused into an
irregular stream, replace the dif fuser immediately .
T ip 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 spray -
ing to reduce the risk of accidentally triggering the gun if it is
dropped
or bumped.
Spray T ip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, lock the gun trigger safety im -
mediately. ALWAYS follow the PRESSURE RELIEF PROCE-
DURE,
below, and then remove the spray tip to clean it.
NEVER wipe of f build–up around the spray tip until the pressure
is fully relieved and the gun trigger safety is locked.
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious injury, including fluid injection,
splashing
fluid or solvent in the eyes or on the skin, or injury from
moving parts or electric shock, always follow this procedure
whenever
you shut of f the sprayer , when checking or servicing
any part of the spray system, when installing, cleaning or chang -
ing
spray tips, and whenever you stop spraying.
1. Lock the gun trigger safety .
2. Turn the ON/OFF switch to OFF.
3.
Unplug the power supply cord.
4. Unlock the gun trigger safety. Hold a metal part of the gun
firmly to the side of a grounded metal pail, and trigger the gun
to relieve the pressure.
5. Lock the gun trigger safety .
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, VER Y SLOWL Y loosen the tip guard retaining nut
or hose end coupling to relieve the 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 chemi-
cals 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 injury , or fire, explosion or prop -
erty 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 respira -
tor
as recommended by the fluid and solvent manufacturer .
System Pressure
This sprayer can develop 2500 psi (172 bar) MAXIMUM
WORKING PRESSURE.
Be sure all spray equipment and ac -
cessories 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 compat -
ible with the wetted parts shown in the TECHNICAL DATA on
page 28. Consult your chemical supplier to ensure compatibility .
Do
not use 1,1,1-trichloroethane, methylene chloride, other ha -
logenated hydrocarbon solvents or fluids containing such sol-
vents in this equipment, which contains aluminum and/or zinc
parts.
Such use could result in a serious chemical reaction, with
the possibility of explosion, which could cause death, serious
injury
and/or substantial property damage.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage
or misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious injury or property
damage.
All fluid hoses must have strain reliefs on both ends!
The
strain reliefs help protect the hose from kinks or bends at or
close
to the coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high pres -
sure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the en -
tire hose for cuts, leaks, abrasion, bulging cover , or damage or
movement of the hose couplings. If any of these conditions ex -
ist, replace the hose immediately . DO NOT try to recouple high
pressure hose or mend it with tape or any other device. A re-
paired 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 sur -
faces
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 re -
sistance 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 un-
grounded
or poorly grounded hose can make your system haz -
ardous. 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 un-
plugging a power supply cord or using a gasoline engine.
Sparks can ignite fumes from solvents and the fluid being
sprayed, dust particles and other flammable substances,
whether you are spraying indoors or outdoors, and can cause
a fire or explosion and serious injury and property damage.
If you experience any static sparking or even a slight shock
while
using this equipment, ST OP SPRA YING IMMEDIA TELY.
Check the entire system for proper grounding. Do not use the
system again until the problem has been identified and cor-
rected.
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 instruc -
tions 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, both
equipped with an undamaged three-prong plug, into a prop -
erly grounded outlet. Do not use an adapter. All extensions
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 prop-
erly
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 card-
board, 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 4, and remove the spray tip before flushing. Hold a
metal
part of the gun firmly to the side of a grounded metal pail
and use the lowest possible fluid pressure during flushing.
MOVING P ARTS 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 4
before checking or servicing any part of 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 – particularly the General Standards, Part 1910, and
the Construction Standards, Part 1926 – should be consulted.

usées ou abîmées peut causer des dégâts à l’appareil ou des
ruptures
de pièces et entraîner une injection de liquide ou d‘au -
tres blessures sérieuses, un incendie, une explosion ou d’au-
tres
dégâts.
Toujours porter une protection pour les yeux, de gants, des vête -
ments protecteur et un dispositif pour la respiration correspon-
dant aux recommandations des fabricants de fluides et sol-
vants.
Pression
Ce pulvérisateur peut produire une PRESSION MAXIMUM DE
TRAVAIL
172 bar ( 2500 lb/po. @ ) S’assurer que tous les éléments
du pulvérisateur et ses accessoires sont conçus pour résister
à la pression maximum de travail de ce pulvérisateur. NE PAS
dépasser
la pression maximum de travail d’aucun des éléments
ou accessoires utilisés avec cet appareil.
MESURES DE SECURITE CONCERNANT LES TUYAUX FLEXIBLES
Compatibilité chimique des corps
BIEN S’ASSURER que tous les corps des solvants utilisés sont
chimiquement compatibles avec les parties mouillées indi-
quées dans les “Données techniques”, à la page 24. Toujours
lire
soigneusement les documents et brochures du fabricant des
fluides et solvants utilisés avant de s’en servir dans ce pulvérisa -
teur.
Le fluide à haute pression circulant dans les tuyaux peut être
très
dangereux. En cas de fuite sur le tuyau, de fissure, déchiru -
re
ou rupture à la suite de l’usure, de dégâts ou d’une mauvaise
utilisation, les projections de fluide haute pression qui en pro-
viennent peuvent entraîner des blessures graves par pénétra-
tion
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 contri-
buent
à éviter la formation de pliures, de boucles ou de nœuds
sur les tuyaux qui pourraient entraîner la rupture du tuyau à l’en -
droit
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 ti-
rant sur le tuyau. Ne pas utiliser de fluides ou de solvants que
ne
sont pas compatibles avec l’enveloppe intérieur ou extérieu -
re
de tuyau. NE P AS 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 essen -
tielle
pour maintenir la mise à la terre de l’ensemble de vaporisa -
tion. Vérifiez la résistance électrique de vos tuyaux à fluides et
à
air , au moines une fois par semaine. Si votre tuyau ne compor -
te
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 véri -
fiez la résistance. Si celle–ci dépasse les limites recomman-
dées, 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 convenable-
ment
reliées ou à la masse ou à la terre, des étincelles peuvent
se produire et l’appareil risques d’être dangereux. Des étincel-
les peuvent Également se produire à l’occasion du branche-
ment
ou du débranchement du cordon d’alimentation ou de l’uti -
lisation 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 in-
flammables, 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.
S’il se produit des étincelles d’électricité statique, ou si vous res -
sentez la moindre décharge, ARRETEZ IMMEDIATEMENT LA
PULVERISATION.
Vérifiez que le système avant que le problè -
me 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 ter -
re 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 loca-
les.
S’ASSURER que tous le équipements de pulvérisation sui -
vants sont bien reliés à la terre:
1. Pulvérisateur: Brancher le cordon d’alimentation ou la
rallonge qui doivent être équipés d’une prise à 3 fiches en
bon état, dans une prise de courant convenablement mise à
la terre. Ne pas utiliser d‘adapteur. Toutes les rallonges
doivent
avoid 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 réglemen-
tations
locales.
5. Objets, matériel ou surfaces recevant la pulvérisation: obser -
ver
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 pa-
pier 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 ap-
puyée contre le côté d’un seau
en métal puis appuyer sur la

funcionando bien antes de cada uso. No sacar ni modificar nin -
guna pieza de la pistola pues podría causar el malfunciona-
miento
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 posi-
ción “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. Re -
visar 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 metáli -
co, sosteniéndola bien firme contra él. Utilizando la presión más

perso 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 llega -
ra
a obstruirse mientras está pulverizando, enganchar el pesti -
llo de la pistola de inmediato. SIEMPRE seguir el procedimien-
to de descarga de presión y después sacar la boquilla para
limpiarla

Compatibilidad de fluido
Siempre leer las instrucciones del fabricante del fluido y solven -
te 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 acoplamien -
tos
o cerca de ellos, los que podrían traducirse en roturas de la
manguera.
Antes de usarlas, APRET AR 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 revisar -
la en busca de cortaduras, escapes, abrasión, cubierta abulta -
da, o acoplamientos sueltos o dañados. Si llegara a encontrar -
se cualquiera de estas condiciones, reemplazar de inmediato
la
manguera. NO intentar reacoplar una manguera de alta pre -
sión 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 solven -
tes
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 pulveriza -
dor . Es indispensable revisar la resistencia eléctrica máxima de
las mangueras de aire y de fluido por lo menos una vez a la se -
mana. Si la manguera no tiene una etiqueta en la cual se espe -
cifica la resistencia eléctrica máximum, ponerse en contacto
con
el proveedor o fabricante de la manguera para la informa -
ción sobre los límites de resistencia. Usar un metro de resisten -
cia
en la gama apropiada para comprobar la resistencia; si ex -
cede 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 infor -
mación 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 man -
guera
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 eléctri -
co o al usar un motor de gasolina. Estas chispas pueden infla -
mar
los vapores de los solventes y el chorro de fluido pulveriza -
do, partículas de polvo y otras sustancias inflamables, sea al
aire
libre o bajo techo, lo que podría causar una explosión o in -
cendio
y graves lesiones corporales y daños a la propiedad.
Si ocurre una chispa de electricidad estática o incluso un ligero
choque eléctrico mientras se usa el equipo, DEJAR DE PUL VE-
RIZAR 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 . CONSUL T AR el có -

Setup
1. Connect the hose and gun. Remove the plastic
cap from the outlet nipple (C), and connect a
50 ft. (15 m) (minimum length) fluid hose to it.
Connect the other end of the hose to the spray
gun. Don’t use thread sealant, and don’t install the
spray tip yet!
T o avoid damaging the pressure control, which may
result in poor equipment performance and compo -
nent damage, follow these precautions:
1. Always use a minimum of 50 ft. (15.2 m) nylon
spray hose.
2. Never use a wire braid hose as it is too rigid to
act as a pulsation dampener .
3. Never install any shutof f device between the
outlet of the pressure control and the main
hose.
4.
Never allow flushing water or water base paint
to freeze in the system.
CAUTION
2. Fill the packing nut/wet cup (D) 1/3 full with
throat seal liquid, supplied. Keep the wet cup filled
to help protect and prolong the life of the pump’ s
throat packings.
3. Be sure the electrical service is 120 V AC, 60
Hz, 15 Amp (minimum) and that the outlet you use
is properly grounded.
Use a grounded extension cord which has 3 wires
of a minimum 12 gauge size, and a maximum of
200 ft. (61 m) long. Longer lengths may af fect
sprayer performance.
Do not remove the grounding prong of the power
supply cord plug, and do not use an adapter .
4.
Set the pressure control by turning the knob (B)
to the lowest setting.
5. Be sure the ON/OFF switch (A) is OFF .
6. 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 a
spark igniting the spray vapors.
7. An optional filter kit, part no. 820–080, is avail -
able. Instructions are included with it.
8. Flush the pump. An important part of the care
and maintenance of your sprayer is proper flush -
ing. Refer to page 12.
CAUTION
Never operate the sprayer without the drain valve
(19) in place. The drain valve is used to help relieve
system pressure and to help prime the sprayer .
Do not attach a spray hose to the drain valve; do -
ing so could result in costly damage to the pressure
control.

9.
Prepare the paint as instructed by the manufac -
turer
. Remove any skin that may have formed. Stir
the paint to dissolve pigments. Strain the paint
through a fine, nylon–mesh bag (available at most
paint dealers) to remove particles that might clog
the spray tip. This is probably the most important
step toward trouble–free spray painting.
New paint seldom needs thinning. Add solvent to
old and remixed paints to replace the solvent lost
through evaporation. Do not add too much solvent
as thin paint is hard to control and doesn’t cover
very well. Follow the paint manufacturer ’ s recom -
mendations on thinning.

820-007
Setup
10. Prime the sprayer .
a.
Close the drain valve (19). Don’t install the
spray tip yet! See Fig. 1 .
b.
Put the suction tube into the paint container .
c. T
urn the pressure adjusting knob (B) all the
way counterclockwise to lower the pressure
setting.
d.
Unlock the gun trigger safety .
e.
Hold a metal part of the gun firmly against and
aimed into a grounded metal waste container .
f.
Squeeze the trigger and hold it open, turn the
ON/OFF switch to ON, and slowly increase the
pressure setting until the sprayer starts.
g. Keep the gun triggered until all air is forced out
of the system and the paint flows freely from
the gun.
h. Release the trigger and lock the gun trigger
safety.
NOTE:
If the pump is hard to prime, place a container
under the drain valve and open it. Let the sprayer run
until paint is running through the drain valve. Close the
drain valve. This method bleeds the air from the pump.
Then release the gun trigger safety and trigger the gun
to prime the hose as instructed previously , under
Prime the Sprayer .
11.
Check all fluid connections for leaks. If any are
found, follow the Pressure Relief Procedure ,
page 4, before tightening connections.
Adjust the Spray Pattern
Increase the pressure adjusting knob setting just until
spray from the gun is completely atomized. Use the
lowest pressure necessary to get the desired results,
which helps prolong the life of your sprayer and mini
-
mizes paint lost by overspray .
T
est the spray pattern on a piece of light colored paper .
The tip position determines the direction of the pattern
width. Before adjusting the pattern always follow the
Pressure Relief Procedure W arning on page 4.
Cleaning and Clearing the Spray Tip
WARNING
To reduce the risk of injection injury , DO NOT hold
your hand, body , or a rag in front of the spray tip
when cleaning or checking a clogged tip. Always
point the gun toward the ground or into a waste
container when checking to see if the tip is clear .
DO NOT try to “blow back” paint; this is NOT air
spray equipment.
If the spray tip clogs while spraying, lock the gun
trigger safety immediately . DO NOT wipe build up
of f the gun or tip until pressure is fully relieved. See
the Pressure Relief Procedure W arning on page
4.
Clean out the front of the spray tip frequently during
daily operation. First, follow the Pressure Relief Pro -
cedure W arning page 4. Then use a solvent soaked
brush to clean the spray tip and to keep build up from
drying and clogging the spray tip.

Flushing
When To Flush
1. Before using your new sprayer . Y our new spray -
er was factory tested with motor oil and the oil was
left. in it to protect the pump parts.
Before using water–based paint , flush out the oil
with mineral spirits, followed by soapy water , and
then with clean water .
Before using oil–based paint, flush out the oil with
mineral spirits only .
2.
Whenever you change the paint color. Flush with
a compatible solvent such as mineral spirits or wa -
ter.
3.
Whenever you change from water–based to oil–
based paint. Flush with soapy water , then with
mineral spirits.
4. Whenever you change from oil–based to water–
based paint. Flush with mineral spirits, followed
by soapy water , then with clean water .

spirits
with soapy water and then with clean water .
Before using oil–based paint: Flush out mineral
spirits with the fluid to be sprayed.
How To Flush
1. Follow the Pressure Relief Procedure on page
4.
2.
Pour 1/2 gallon (2 liters) of compatible solvent (see
When to Flush) into a bare metal pail. Put the
pump suction tube in the pail.
3. Be sure the pressure control knob is set at mini -
mum, and the drain valve is closed.
4. Remove the spray tip from the gun.
5. Unlock the gun trigger safety .
WARNING
T o reduce the risk of static sparking and splashing,
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 when flushing.
0667
6. Point the spray gun into a grounded metal pail,
and with a metal part of the gun firmly touching the
metal container , squeeze the gun trigger . This
procedure helps reduce the risk of static
sparking and splashing. With the gun triggered,
turn the ON/OFF switch to ON and slowly turn the
pressure adjusting knob clockwise just until the
sprayer starts. Keep the gun triggered until clean
solvent comes from the nozzle.
7. Release the trigger . Open the drain valve to flush
it.
8.
Release the trigger and lock the gun trigger safety .
Close the drain valve.
9. Check all fluid connections for leaks. If there are
any leaks, follow the Pressure Relief Procedure ,
on page 4. T ighten the connections, start the
sprayer , and check to be sure the leaking has
stopped.
10.
Remove the suction tube from the pail. Unlock the
gun trigger safety and trigger the gun into a
grounded metal pail to force solvent from the hose.
Do not let the pump run dry for more than 30
seconds to avoid damaging the pump pack-
ings!
11. Lock the gun trigger safety , turn the sprayer to
OFF , and unplug the sprayer . Open the drain
valve. Remove the suction tube and clean sepa -
rately
. Flushing may not remove all sediment.
12. If you flushed with mineral spirits and are going to
use a water–based paint, flush again with soapy
water , and then with clean water . Then follow the
Pressure Relief Procedure on page 4.

820-007
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.
Begin moving the gun in a horizontal direction at a
steady rate. Start the spray stroke of f the target sur -
face 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 0072
Fig. 2
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 uni -
form pattern alternately from right to left, then left to
right, provides a professional finish.
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 necessary to get the desired
paint atomization, which helps prolong the life of your
sprayer and minimizes paint lost by overspray .
OVERLAP EACH STROKE 50%
0672
Fig. 3
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 .
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 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 se -
cured with masking tape.
0673
Fig. 4
Nearby objects. Move objects such as automobiles,
picnic tables, lawn furniture, etc. up–wind of the sur -
face to be sprayed. In the case of a nearby home,
make a protective barrier by hanging plastic between
two long poles.

14 820-007
Shutdown and Care
1. Check the packing nut/wet cup daily . First, fol -
low the Pressure Relief Procedure W arning,
page 4. The packing nut should be tight enough
to stop leakage – no tighter . Use a rod and a light
hammer to adjust the nut. See Fig. 5. Don’t over -
tighten! Overtightening may cause binding and
excessive packing wear .
CAUTION
Do not nick the threads of the displacement pump,
which may extend above the bearing housing,
when adjusting the packing nut. A nick in the
threads can strip the threads in the bearing housing
when installing or removing the pump.
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 on page 12.
CAUTION
Never leave water or water–based paint in the
sprayer overnight to prevent pump corrosion and
freezing in the pressure control or pump, during
cold weather , which can damage the sprayer .
3. For very short shutoff periods
, leave the suction
tube in the paint follow the Pressure Relief Proce -
dure W arning, page 4, and clean the spray tip.
4. W rap the hose around the sprayer when storing
it , even if only overnight, to help protect the hose
from damage.

Installing the Pump
1. To reinstall the pump, rotate the crankshaft so that
the connecting rod (64) is in its lowest position.
Pull the pump piston rod (47) about 1–1/2 inches
out of the cylinder (46), and turn the rod so the pin
hole is about 90  from the outlet nipple (22).
Screw the cylinder locknut (103) all the way down.
2. Screw the pump (26) into the drive assembly (65)
until the holes in the piston rod and the connecting
rod are aligned. Insert the pin (57) and push the
retaining spring (55) down over the pin.
3. Screw the pump cylinder completely into the drive
assembly; you will feel some resistance from the
packings. Now turn the cylinder back until the out -
let nipple (22) faces back. Screw the hose (20)
onto the nipple; tighten it securely . T o avoid having
the cylinder locknut (103) loosen due to vibration,
tighten the locknut up against the drive housing to
70 ft–lb (95 N.m).
4. Reassemble remaining parts reverse from disas -
sembly.
NOTE:
Use Repair Kit No. 820–549 to repair the
pump. See page 27. Use all the parts in the kit, even if
the old ones look good. Old and new parts do not seal
together well, and the pump may leak.
Disassembling the Pump
1. Remove the pump from the sprayer as described
above.
2.
Unscrew the intake valve (48) from the cylinder
(46). If the valve is seized in the housing, squirt
penetrating oil around the threads and gently tap
around the housing with a light hammer to loosen.
See Fig. 7 and 9. Remove the ball guide (40), the
stop pin (39) and the ball (28). Clean and inspect
the parts for wear or damage.
NOTE: T est the intake valve by filling it with solvent
and seeing if any solvent leaks past the ball. It
shouldn’t leak. The valve must be clean for this test;
any dirt will hold the ball of f the seat and let the solvent
leak past.

Displacement Pump
3. Unscrew and remove the packing nut (38). Using a
rubber mallet, tap the piston rod (47) down and
pull it out through the bottom of the cylinder (46).
See Fig. 8 and 9.
4. Remove the glands (34 & 37) and the packings (35
& 36).
5. Clean and inspect the piston rod and the inside of
the cylinder for nicks, scratches or scoring which
could cause leaking or premature wear of the
packings.
6. Clamp the flats of the piston rod in a vise. Use a
wrench to loosen the nut (33) and unscrew the pis -
ton valve (49) from the piston rod. Remove the ball
(27), nut (33), glands (30 & 32), packings (31 &
43), seal (29), and washer (45).
Assembling the Pump
1. When assembling the pump, coat the packings,
the piston rod and the inside of the cylinder with
oil.
2.
When reassembling the piston, install the new
glands and packings in the correct order , alternat -
ing the leather and plastic packings. See Fig. 8.
The “V” of the packings must face up against the
fluid pressure. See Fig. 9. T ighten the nut (33) to
10.5 in–lb (1.2 N.m) to seat the packings, then
back of f the nut and hand tighten it.
3. Place a new ball (27) in the piston rod (47). Apply
locking compound to the threads of the piston
valve (49) and screw it into the rod hand tight, 1–2
in–lbs (0.1 1–0.22 N.m) torque. T ighten the nut
against the piston rod to 18–20 ft–lb (24–27 N.m)
torque, without changing the tightness of the nut
against the packings.
4. Install the throat packings, glands and packing nut,
leaving the packing nut loose. The “V” of the pack -
ings must face down against the fluid pressure.
Alternate the plastic packings (36) and the leather
packings (35). See Fig. 8.
5. Insert the piston rod (47) through the bottom of the
pump cylinder (46).
6. Assemble and install the intake valve (48); torque
it to 75–85 ft–lb (100–1 15 N.m). T ighten the pack -
ing nut (38) just enough to stop leakage––no tight -
er.
