WARNING
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before opera:ing equipment.
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.
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
ALWAYS have the tip guard in place on the spray gun when
spraying.
The gun diffuser breaks up spray and reduces the risk of injec-
tion when the tip is not installed. Check diffuser operation
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.

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 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, splashing in the eyes, injury from splashing fluid or solvent in the
eyes or on the skin, 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. (11 Engage the gun safety latch. (2) Turn the ON/OFF switch to OFF. (3) Unplug the power supply cord. (41 Disengage
the gun safety latch. (5) Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve
pressure. (61 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 nor 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.

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 Press&e
This sprayer can develop 3ocyI psi 1207 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 working pressure of any component or accessory used in the
system.
Fluid Compatibility
BE SURE that all fluids and solvents used are chemically compatible with the wetted parts shown in the Technical Data on
the back cover. Always read the fluid and solvent manufacturer’s literature before using them in this sprayer.
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. rf any of these condgions
exist, replace the hose immediatelv. DO NOT trv to recouole
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 fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT expose Grace hose to temperatures above 180°F
KW’C) or below -4W’F (-40°C).
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a
grounded spray system. Check the electrical resistance of your
air and 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 im-
mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also read
FIRE OR EXPLOSION
HAZARD.
Static electricity is created by the high velocity 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. 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 ml
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 IMMEDI-
ATELY.
Check the entire system for positive 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 jo&ed in the spray area.
CHECK vour local electrical code for detailed aroundino instruction; for your area and type of equipment-BE SURE to
ground all of this spray equipment:
1.
2.
3.
4.
5.
6.
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.
Fluid hoses: use only grounded hoses with a maximum of
500 feet (150 ml combined hose length to ensure grounding continuity. Refer to
Hose Grounding Continuity.
Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer.
Object being sprayed: according to local code.
All solvent pails used when flushing, according to local
code. Use only metalpails, which are conductive. Do not
place the pail on a non-conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.
To maintain grounding continuity when flushing or relievingpressure, 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 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 i :‘:.,..:. :
.
Moving parts can pinch or amputate your fingers or other
bodv Darts. KEEP CLEAR of movina oarts when startina or
operating the sprayer. Unplug the sp;ayer and relieve pressure
before checking or servicing the sprayer to prevent it from
starting accidentally.

MESURES DE SECURITE CONCERNANT LES TUYAUX FLEXIBLES
Le fluide a haute pression circulant dans les tuyaux peut dtre
t&s dangereux. En cas de fuite sur le tuyau, m&me minuscule,
de fissure, dechirure ou rupture a la suite de I’usure, de degdts
ou d’une mauvaise utilisation, les projections de fluide haute
pression qui en proviennent peuvent entrainer des blessures
graves par pen&ration sous la peau ou par contact, ainsi que
des degdts materiels.
TOUS LES TUYAUX FLEXIBLES DOIVENT AVOIR DES
RESSORTS SPIRALE DE PROTECTION!
Les spirales de
protection contribuent a Bviter la formation de pliures, de
boucles ou de noeuds sur les tuyaux qui pourraient entrainer la
rupture du tuyau a I’endroit du raccord ou a son voisinage.
SERRER FERMEMENT tous les raccords avant chaque utilisa-
tion. Le fluide sous pression peut faire sauter un raccord
desserre ou produire un jet a haute pression s’echappant par le
raccord.
NE JAMAIS utiliser un tuyau endommage. Avant chaque
utilisation, verifier entierement chaque tuyau pour deceler les
coupures, fuites, abrasions, boursouflures de I’enveloppe ou
toute autre deterioration ou jeu des raccords. Si I’on constate
I’une de ces deteriorations, il faut remplacer le tuyau immediatement. NE PAS essayer de refaire le raccord d’un tuyau
haute pression ni de r&parer le tuyau avec du ruban adhesif ou
RISQUES D’INCENDIE OU D’EXPLOSION
De l’electricite statique est produite par le passage du fluide a
grande vitesse dans la pompe et dans les tuyaux. Si toutes les
pieces de I’appareil de pulverisation ne sont pas convenablement reliees a la masse ou a la terre, des Btincelles peuvent se
produire et I’appareil risque d’etre dangereux. Des Btincelles
peuvent Bgalement se produire a I’occasion du branchement
ou du debranchement du cordon d’alimentation. Les Btincelles
sont suffisantes pour allumer les vapeurs de solvants et le
fluide pulverise, les fines particules de poussiere ainsi que
d’autres substances inflammables, quand on pulverise a I’interieur ou a I’exterieur, et elles peuvent causer un incendie ou
une explosion, ainsi que des blessures graves et des degats
materiels. Toujours brancher le pulverisateur dans une prise se
trouvant a au moins 6 m (20 piedst de I’appareil et de I’endroit
ou se fait la pulverisation. Ne pas brancher ou debrancher un
cordon d’alimentation quel qu’il soit dans la zone air se fait la
pulverisation quand il y a le moindre risque que des vapeurs
encore presentes dans I’air prennent feu.
Mise a la terre ou d la masse
Pour reduire les risques de production d’etincelles d’electricite
statique, le pulverisateur et tous les Bquipements utilises ou se
trouvant dans la zone de pulverisation doivent etre relies 8 la
terre ou a la masse. Pour connaitre le detail des instructions de
mise a la terre dans la region et le type particulier d’equipement, CONSULTER le code ou les reglementations Blectriques
locales. S’ASSURER que tous les Bquipements de pulverisa-
tion suivants sont bien relies a la terre:
1. PuWrisateur: Brancher le cordon d’alimentation ou la
rallonge qui doivent dtre equip& d’une prise B 3 fiches en bon
&at, dans une prise de courant convenablement mise a la
terre. Ne pas utiliser d’adaptateur. Toutes les rallonges doivent
avoir 3 fils et etre prevues pour 15 amperes.
par tout autre moyen. Un tuyau repark ne peut pas resister au
fluide sous pression.
MANIPULER LES TUYAUX AVEC PRECAUTION ET
CHOISIR SOIGNEUSEMENT LEUR CHEMIN. Ne pas deplacer
le fluide en tirant sur le tuyau. Ne pas utiliser de fluides ou de
solvants qui ne sont pas compatibles avec I’enveloppe interieure ou exterieure du tuyau. NE PAS exposer le tuyau a
des temperatures superieures a 82°C (180°F) ou inferieures a
-40°C (-40°F).
Continuit6 de la mise B la terre des tuyaux
Une bonne continuite de la mise a la terre des tuyaux est
essentielle pour maintenir la mise a la terre de I’ensemble de
vaporisation. Verifiez la resistance Blectrique de vos tuyaux a
fluides et a air, au moins une fois par semaine. Si votre tuyau
ne comporte pas d’etiquette qui precise la resistance Blectrique maximum, prenez contact avec le fournisseur de tuyaux
ou la fabricant pour avoir les limites de resistance maximum.
Utilisez un metre de resistance de la gamme appropriee pour
votre tuyau et verifiez la resistance. Si celle-ci depasse les
limites recommandees, remplacez le tuyau immediatement.
Un tuyau sans mise a la terre ou avec une mise a la terre incorrecte peut entrainer des risques pour votre systeme. Lisez

PELIGRO POR MAL US0 DEL EQUIP0
Seguridad general
Cualquier mal uso del equip0 pulverizador o 10s accesorios, tal
coma sobrepresurizacicn, modificacibn de piezk, uso de
materiales y productos quimicos incompatibles, o utilizaci6n
de piezas dafiadas o desgastadas, puede hacen que se rompan
y causen la inyeccibn de fluid0 u otras lesiones corporales
graves, incendio, explosibn o dahon a la propiedad.
NUNCA alterar o modificar ninguna pieza de este equipo; el
hacerlo podria causar una averia.
REVISAR con regularidad el equip0 pulverizador y reparar o
reemplazar de inmediato las piezas dafiadas o desgastadas.
Presih del sistema
Esta pulverizadora puede desarrollar 207 barias (3000 psi) de
PRESlON DE TRABAJO MAXIMA. Asegurar que todo el
equip0 pulverizador y sus accesorios tienen la capacidad para
aguantar la presi6n maxima de trabajo de esta pulverizadora.
NO exceder la presi6n maxima de trabajo de ninglin com-
ponente o accesorio de este sistema.
Compatibilidad de fluid0
ASEGURAR que todos 10s fluidos y solventes usados son
quim,icamente compatibles con las piezas mojadas ilustradas
en Ia, hoja de datos tecnicos en la contratapa. Siempre leer las
instrucciones del fabricante del fluid0 y solvente antes de
usarlos en esta pulverizadora.
SEGURlDAD EN EL US0 DE LAS MANGUERAS
El fluid0 que pasa a alta presi6n por las mangueras puede ser
muy peligroso. Si en la manguera se desarrolla un escape pequefio, una rotura o rajadura debido a cualquier tipo de
desgaste, dafio o maltrato, el chorro a alta presibn emitido por
alli puede causar una lesi6n por inyecci6n u otras lesiones cor-
porales graves o dafion a la propiedad.
iTODAS LAS MANGUERAS PARA FLUIDOS TIENEN
WE TENER GUARDAS DE RESORTE!
Estas protegen las
mangueras contra dobleces o retorceduras en 10s acoplamientos o cerca de ellos, 10s que podrian traducirse en roturas de la
manguera.
Antes de usarlas, APRETAR bien firmes todas las conexiones.
El fluid0 a alta presi6n puede desalojar un acoplamiento suelto
o dejar que por BI escape un chorro a alta presion.
NUNCA usar una manguera que esta dafiada. Siempre,
revisarla en busca de cortaduras, escapes, abrasirkr, cubierta
abultada, o acoplamientos sueltos o dafiados. Si llegara a en-
contrarse cualquiera de estas condiciones. reemplazar de in-
mediato la manguera. NO intentar reacoplar una manguera de
alta presi6n o enmendarla con cinta adhesiva u otro material
similar. Una manguera que ha sido remendada no aguante el
fluid0 a alta presi6n.
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 dela manguera. NO exponer
las mangueras a temperaturas sobre 82°C (180°F) o bajo
-40°C (-40°F).
Continuidad del circuit0 de puesta a tierra de la
manguera
La continuidad del circuit0 de puesta a tierra apropiado es
esencial para mantener conectado a tierra el sistema
pulverizador. Es indispensable revisar la resistencia electrica
maxima de las mangueras de aire y de fluid0 por lo menos una
vez a la semana. Si la manguera no tiene una etiqueta en la
cual se especifica la resistencia electrica maxima, ponerse en
contact0 con el proveedor o fabricante de la manguera para la
informaci6n sobre 10s limites de resistencia. Usar un metro de
resistencia en la gama apropiada para comprobar la resistencia; si excede 10s limites recomendados, reemplazarla de inmediato. Es muy arriesgado tener una manguera sin puesta a
tierra o con la puesta a tierra en malas condiciones. Leer tambien la informaci6n sobre
RIESGO DE INCENDIO 0 EXPLO-
SION, mas arriba.
PELIGRO DE INCENDlO 0 EXPLOSION
El flujo a alta velocidad del fluid0 al pasar por la bomba y
manguera crea electricidad estatica. Si todas las partes del
equip0 pulverizador no tienen buena tierra, pueden ocurrir
chispas, convirtiendo al sistema en algo peligroso. Tambien,
pueden producirse chispas al enchufar o desenchufar el cord6n ektrico. Estas chispas pueden inflamar 10s
vapores
de
10s solventes y el chorro de fluid0 pulverizado, particulas de
polvo y otras sustancias inflamables, sea al aire libre o bajo
techo, lo que podria causal una explosi6n o incendio y graves
lesiones corporales y daAos a la propiedad. Enchufar siempre
la pulverizadora a un tomacorriente que se encuentre a por lo
menos 6 m (20 pies) de la maquina y del area que se va a
rociar. No enchufar o desenchufar ningljn cord&n electrico en
el lugar donde se esta rociando cuando todavia exista
la
posibilidad de que queden vapores inflamables en el aire.
Puesta a tierra
Para reducir el riesgo de chispas estaticas, conectar a tierra la
pulverizadora y todo el otro equip0 de pulverizar que se use o
se encuentre en el lugar que se va a rociar. CONSULTAR el
c6digo elktrico 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 equip0
pulverizador:
1. Pulverizadora: enchufar el cord6n electrico, 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 10s 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
tambien al parrafo sobre
continuidad a tierra de la
manguera.
3. Pistola: hater la puesta a tierra conectandola a una
manguera de fluid0 y pulverizadora bien conectadas a tierra.
4. Objet0 que se esr8 rociando: de conformidad con el c6digo
local.
5. Todos /OS baldes de solvente usados durante el lavado, de
conformidad con el cddigo local. Usar solamente baldes de
metal, que Sean conductivos. No colocar el balde en una
superficie no conductiva, coma papel o cart6n, que inter-
rumpe la continuidad a tierra.
6. Para mantener la continuidad a tierra durante et lavado o
descarga de presidn, siempre apoyar una parte metalica de la
pistola bien firme contra el costado del balde de metal,
despues apretar el gatillo.
Seguridad durante el lavado

Your new UltraTM 333 Sprayer functions and operates
differently than other airless paint sprayers. This section
will help you become familiar with the sprayer before
operating it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, the pressure adjusting control knob, a pressure
sensing device, and a current overload circuit breaker
with a manual reset button. Its function is to control the
motor speed so that the sprayer maintains constant
fluid pressure at the pump outlet.
Motor
The DC motor has sealed bearings and replaceable
motor brushes. Its function is to drive the displacement
pump at the rate needed to supply sufficient paint
volume at the selected pressure.
Working together, the pressure control and motor
cause the pump to cycle whenever there is fluid or
pressure demand. When the pump is cycling, the motor
sounds like an automobile starter cranking. When the
pump is not cycling, the motor hums, hums intermittently, or appears to have shut itself off. However, there
will still be power to the sprayer and it will stay
pressurized and ready to use unless you manually shut it
off and relieve pressure.
Because the motor is DC, it is less sensitive to low
voltage or voltage fluctuations than an AC motor, and
an extension cord of up to 150 feet (45 m) can be used.
Drive Assembly
The sealed drive assembly transfers power from the DC
motor to the displacement pump.
8
307643
Displacement Pump
The positive displacement, volume-balanced pump pro-
vides equal fluid delivery on both the up and down
pump strokes. The pump has a wet-cup which, when
filled with Grace Throat Seal Liquid, helps prevent
damage to the throat packings and piston rod.
Fluid Filter
The fluid filter provides the final paint straining to help
avoid clogs in the hose and spray tip. The filter includes
a reusable element and a drain valve for relieving fluid
pressure when shutting off the sprayer.
Hoses
The grounded, nylon spray hoses have spring guards on
both ends. The 50 foot (15.2 m) hose has a l/4 in. ID.
The 3 foot (0.9 m), 3/16 in. ID whip hose allows flexible gun movement. The nylon hose material acts as a
pulsation dampener to absorb pressure fluctuations.
Spray Gun & Reverse-A-Clean Ill Spray Tip
Both the “Contractor” and “Flex” spray guns include a
trigger safety which prevents accidental triggering
when it is engaged (see the WARNING on page 3):The
Reverse-A-Clean III
spray
tip uses high pressure fluid to
remove clogs from the spray tip without removing it
from the gun. It includes a safety tip guard which helps
reduce the risk of injection injury.

SETUP
1.
Connect Hose and Gun (Refer
to Fig 1.1
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!
2. Two Gun Hookup.
(Refer to Fig 1.1 Remove the
plug from the tee which holds the fluid filter to the
sprayer and install an accessory l/4 npt ball valve.
Connect an accessory hose and gun to the ball
valve.
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 for onegun operation. Never plug this outlet.
3. Fill Packing Nut/Wet-Cup (See
Fig 2.1
Fill the packing nut/wet-cup l/3 full with Grace
Throat Seal Liquid (TSL), supplied.
4. 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
Fig
i-MAlN FLUID HOSE
minimum 12 gauge size, and a maximum of
150 ft (45 m) long. Longer lengths may affect
sprayer performance.
5. 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 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.
Fig 3
6. Flush the pump
to remove the No. 10 motor oil
which was left in to protect pump parts after fac-
tory testing.
a.
Before using water-base paint,
flush with
mineral spirits followed by soapy water, and
b. Stir the paint to dissolve pigments.
then a clean water flush.
7. Prepare the paint
according to the manufacturer’s
recommendations.
a.
Remove any skin that may have formed.
b.
Before using oil-base paint,
flush with mineral
spirits only.
c. See ‘*Flushing Guidelines”
on page 12 for
flushing procedure.
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.

WARNING’
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, 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.
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 operate the sprayer 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 the nut completely. Now clear the tip or hose obstruction.
1. Prime the Sprayer with Paint.
a.
Close the filter drain valve (and the secondary
hose ball valve).
b.
Don’t install the spray tip yet!
c.
Put the suction tube into the paint container.
d. Turn the pressure adjusting knob all the way
counterclockwise to lower the pressure setting.
e.
Disengage the gun safety latch.
f.
Hold a metal part of the gun firmly against and
aimed into a metal waste container. See Fig 4.
Squeeze the trigger and hold it open, turn the
ON/OFF switch to ON, and slowly increase the
pressure setting until the sprayer starts. Keep
the gun triggered until all air is forced out of the
system and the paint flows freely from the gun.
Release the trigger and engage the safety.
NOTE:
If the pump is hard to prime, place a container under the drain valve and open it.
When fluid comes from the valve, close it.
Then disengage the gun safety and pro-
ceed as in Step If, above.
g. Check all fluid connections for leaks If any
leaks are found, follow the
Pressure Relief
Procedure Warning,
above, before tightening
the connections.
2.

3. Adjusting the Spray Pattern
a.
Increase the pressure adjusting knob setting
just until spray from the gun is completely
atomized. To avoid excessive overspray and
fogging, and to decrease tip wear and extend
the life of the sprayer, always use the lowest
possible pressure needed to get the desired
results.
b. If more coverage is needed, use a larger tip
rather than increasing the pressure.
c. Test the spray pattern. To adjust the direction
of the spray pattern, engage the gun safety and
loosen the retaining nut. Position the tip so the
groove is horizontal for a horizontal pattern or
vertical for a vertical pattern. Then tighten the
retaining nut.

4. Cleaning a Clogged Tip
WARNING
To reduce the risk of serious bodily injury from injection, use extreme caution when cleaning or
changing spray tips. If the spray tip clogs while
spraying, engage the gun safety latch immediate-
ly, then follow the procedure in Steps 4a-4e,
below.
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 fluid
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 1W. See Fig 6.
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 spraying.
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 .‘.::, ‘:“ ;‘,/ -‘,::jy“ ,:,‘; .l_‘.
1.
Check the packing nut/wet-cup daily.
First
follow the
Pressure Relief Procedure Warning
on
page 10. Be sure the wet-cup is l/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. Over-tightening may cause
binding and excessive packing wear. Use a screwdriver and light hammer to adjust the nut. See
Fig 7.
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
Never leave water or any paint in the sprayer overnight to: (1) prevent pump corrosion; (2) to pre-
vent 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.
4. For very short shutoff periods,
leave the suction
tube in the paint, follow the
Pressure Relief Pro-
cedure Warning
on page 10, 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.

Disassembling the Pump
(Refer to Figures 9 and IO.)
1. Unscrew the intake valve (222) from the cylinder
(216). Remove the gasket (2061, ball guide (2151,
stop pin (207) and ball (204) from the valve. Clean
and inspect the parts for wear or damage, replacing
parts as needed. Always use a new gasket (included in Repair Kit 218-033).
2. Unscrew and remove the packing nut (221) and
plug (201).
3. Use a plastic mallet to tap the piston rod
down,
then pull the rod out through the bottom of the
cylinder.
4.
Remove the throat packings (209, 218) and glands
(211, 212).
5.
Clamp the flats of the piston rod in a vise. Use a
7/8 in. wrench to loosen the retaining nut (214).
Then use the wrench to unscrew the piston valve
(224) from the rod.
6. Remove the backup washer (219). wiper (2051,
packings (208, 217) and glands (213, 220).
Reassembling the Pump
Assembly Notes:
(1) Use Repair Kit No. 218-033 to repair the displace-
ment pump. Reference number in parentheses with
an asterisk, for exampe, (210*), show the parts included in the kit. Use all the new parts, even if the
old ones still look good as the old parts cause the
new ones to wear prematurely.
(2)
Alternate leather and plastic packings as shown in
Fig 3. Notice that the lips of the throat “V” packings face
down,
against pressure, and the lips of
the piston “V” packings
face up,
against pressure.
The lips of the U-cup wiper (205),
face down.
Incor-
rect installation damages the packings and results
in the pump leaking.
(3)
1.

5.
Coat the piston rod, inside of the cylinder and the
packings with a lightweight oil to help prevent
packing damage when inserting the piston rod.
Check the outside of the piston rod (223) and the inside of the cylinder (216) for scoring or scratches. If
the parts are damaged, new packings will not seal
properly. Replace these parts if needed.
Stack the backup washer (219*), wiper (205*),
female gland E?O*), packings f217*, 208”) and
male gland (213”) onto the piston valve. See
Figures 11 & 12.
Tighten the packing retaining nut (214) onto the
piston valve (224) and torque to 3 to 4 in-lb 10.34 to
0.35 N-m)-about finger tight.
Use a pen to make a light mark on the packings
where they align with one of the flats on the nut.
See Fig 11.
Place ball (203) on piston valve (224). Apply
one
drop
of thread locking compound on threads of
valve. Then hand tighten the valve assembly into
the piston rod just until the nut meets the face of
the rod. See Fig 12.

Place the flats of the rod in a vise.
CAUTION
Step
7,
tightening the piston valve into the rod, is
critical. Follow the procedure carefully to avoid
damaging the packings by overtightening.
7. Without changing the tightness of the nut against
the packings,
tighten the nut (214) into the piston
rod to
18
to
20
ft-lbs
(24
to 27 N.m). If the pen mark
on the packings loses alignment, back the nut off
and try again.

and female gland (212*), one at a time, into the top
of the cylinder. See Fig 10.
9.
Install the throat packing nut (221) and plug (201)
but leave loose for now.
10. Insert the piston rod
(223)
through the bottom of
+he pump cylinder, pushing it up until the top of the
piston rod extends l-7/8” (32.2 mm) beyond the
top of the cylinder. See Fig 10.
11. Screw down the cylinder locknut (38) until it is
finger tight at the bottom of the external cylinder
threads.
12. Place flats of the intake valve in a vise. Install a new
gasket 006”) and screw the pump cylinder into the
valve. See Fig 9.
13.
Screw the displacement pump about
3/4
of the
way into the bearing housing
(27).
Hold the pin
(20)
up to the pin hole in the connecting rod assembly
(3)
and continue screwing in the pump until the pin
slides easily into th8 hole. Back off the pump until
the top threads of the pump cylinder are flush with
the face of the bearing housing and the outlet nipple (45) is straight back. Push the retaining spring
(35) into the groove all the way around the connecting rod. Tighten the locknut (38) very tight-about
70 ft-lb (94 N-ml-with a 2 in. open-end wrench
and 8 light hammer.
WARNING
Be sure the retaining spring (351 is firmly in the
groove of the connecting rod,
all the way around,
to prevent if from working loose due to vibration.
See Fig 13.
If the pin works loose, it or other parts could break
off due to the force of the pumping action. These
parts could be projected through the air and result
in serious bodily injury or property damage, including damage to the pump, connecting rod or
bearing housing.
If the locknut (38) loosens during operation, the
threads of the bearing housing (27) will be permanently damaged. Be sure to tighten the locknut
firmly.

14. Tighten the packing nut (221)
just
enough to stop
leakage, but no tighter. Fill the wet-cup/packing
nut l/3 full with Grace TSL.
15. Replace the motor brushes, included with the repair
kit. See page 18.

Remove the motor screws (I 121, washers II 13) and
cover (14). See Fig 14.
Remove the screws (H), inspection covers (J) and
gaskets (K) on each side of the motor. See Fig 14.
Loosen
the brush lead terminal screw and remove
the lead.
Push down on the spring clip slightly then pull the
clip away from and out of the brush holder. Refer to
Fig 15. Keep the spring clip.
Remove and discard the brush.
Inspect the commutator for excessive pitting, burning or gouging.
NOTE:
A black color on the commutator is normal.
Have the commutator resurfaced by a
qualified motor repair shop if the brushes
seem to be wearing too fast.
7. Place a new brush in the holder so the beveled
edges are 8s shown in the first part of Fig 15, and
the brush lead is routed as shown in the second part
of Fig 15.
8. Slowly push the tabbed end of the spring clip into
the brush holder until the clip tab engages in the
holder and the rolled portion of the tension spring
rests squarely on the brush.
9. Route the brush lead to the terminal and tighten the
terminal screws. Be sure the brush lead does not
touch any part of the armature or motor housing.
10. Test the brushes:
a. With the ON/OFF switch OFF, turn the
pressure control knob all the way counterclock-
wise to minimum pressure. Plug in the sprayer.
b. Turn the ON/OFF switch ON and slowly in-
crease the pressure until the motor comes up to
full speed.
c. Inspect the brush and commutator contact area
for excessive arcing. Arcs should not “trail” or
circle around the commutator surface.
11. Reinstall the brush inspection covers, gaskets, and
screws. Reinstall the motor cover, screws and
washers.
