SAFETY W ARNINGS
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating the equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can inject fluid through
your
skin and into your body , and cause extremely serious bodily
injury, including the need for amputation. Also, fluid injected or
splashed
into the eyes or on the skin can cause serious damage.
NEVER point the spray gun at any one or at any part of the body .
NEVER
put your hand or fingers over the spray tip. NEVER try
to “blow back” paint; this is NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYS
follow the PRESSURE RELIEF PROCEDURE , below ,
before
cleaning or removing the spray tip or servicing any sys -
tem 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. Toxicity is a
concern with some exotic coatings injected directly into the
blood
stream. Consultation with a plastic surgeon or reconstru -
ctive
hand surgeon may be advisable .
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly before
each
use. Do not remove or modify any part of the gun; this can
cause a malfunction and result in serious bodily injury .
Safety Latch
Whenever you stop spraying, even for a moment, always set the
gun safety latch in the closed or “safe” position, making the gun
inoperative. Failure to set the safety latch can result in accidental
triggering of the gun.
Diffuser
The gun dif fuser breaks up spray and reduces the risk of fluid in -
jection when the tip is not installed. Check diffuser operation
regularly. Follow the PRESSURE RELIEF PROCEDURE, be-
low,
then remove the spray tip. Aim the gun into a metal pail, hold -
ing
the gun firmly to the pail. Using the lowest possible pressure,
trigger the gun. If the fluid emitted is not dif fused into an irregular
stream, replace the dif fuser immediately .
Tip Guard
ALWAYS have the tip guard in place on the spray gun while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce, but does not prevent, the risk of accidentally
placing your fingers or any part of your body close to the spray
tip.
Trigger Guard
Always have the trigger guard in place on the gun when spraying
to reduce the risk of accidentally triggering the gun if it is dropped
or bumped.
Spray T ip Safety
Use extreme caution when cleaning or changing spray tips. If the
spray tip clogs while spraying, engage the gun safety latch 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 relieves and the gun safety is engaged.
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious bodily injury , including fluid injection,
splashing fluid or solvent in the eyes or on the skin, or injury from
moving parts or electric shock, always follow this procedure
whenever
you shut 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. Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3.
Unplug the power supply cord.
4. Disengage the gun safety latch. Hold a metal part of the gun
firmly to the side of a grounded metal pail, and trigger the gun
to relieve pressure.
5. Engage the gun safety latch.
6. Open the pressure drain valve, having a container ready to
catch
the drainage. Leave the valve open until you are ready
to spray again.
If you suspect that the spray tip or hose is completely clogged,
or that pressure has not been fully relieved after following the
steps
above, VER Y SLOWL Y loosen the tip guard retaining nut
or hose end coupling to relieve pressure gradually , then loosen
completely. Now clear the tip or hose.

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 2
before checking or servicing any part of the sprayer , to prevent
it from starting accidentally .
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible 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 bodily 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 respirator
as recommended by the fluid and solvent manufacturer .
System Pressure
This sprayer can develop 2750 psi (190 bar) MAXIMUM WORK -
ING
PRESSURE. Be sure all spray equipment and accessories
used are rated to withstand the this pressure. DO NOT exceed
the maximum working pressure of any component or accessory
used in the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer must be chemically compatible
with the wetted parts shown in the TECHNICAL DA TA on page
24. 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
bodily
injury and/or substantial property damage.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage or misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious bodily injury or prop -
erty
damage.
ALL FLUID HOSES MUST HA VE 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 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 pres -
sure hose or mend it with tape or any other device. A repaired
hose
cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Keep hoses clear of moving parts
and
hot surfaces of the pump and gas engine. Do not use fluids
or solvents which are not compatible with the inner tube and
cover of the hose. DO NOT expose Graco hoses to tempera-
tures
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, con -
tact the hose supplier or manufacturer for the maximum resis-
tance
limits. Use a resistance meter in the appropriate range for
your hose to check the resistance. If the resistance exceeds the
recommended limits, replace it immediately . An ungrounded or
poorly grounded hose can make your system hazardous. Also
read
FIRE OR EXPLOSION HAZARD, below.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump
and hose. If every part of the spray equipment is not properly
grounded,
sparking may occur , and the system may become haz -
ardous.
Sparking may also occur when plugging in or unplugging
a power supply cord or using a gasoline engine. Sparks can ignite
fumes from solvents and the fluid being sprayed, dust particles
and other flammable substances, whether you are spraying in -
doors
or outdoors, and can cause a fire or explosion and serious
bodily 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 corrected.
Grounding
To reduce the risk of static sparking, ground the sprayer and all
other spray equipment used or located in the spray area.
CHECK
your local electrical code for detailed grounding 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, each
equipped with an undamaged three-prong plug, into a proper -
ly grounded outlet. Do not use an adapater. 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 continu -
ity.
See Hose Grounding Continuity above.
3.
Spray gun: obtain grounding through connection to a properly
grounded fluid hose and sprayer .
4. Object being sprayed: according to local code.
5. Fluid supply container: according to local code.
6. All solvent pails used when flushing, according to local code.
Use only metal pails, which are conductive. Do not place the
pail on a non–conductive surface, such as paper or 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 splash -
ing by following the flushing procedure given on page 9 of this
manual. Follow the PRESSURE RELIEF PROCEDURE on
page
2, and remove the spray tip before flushing. Hold a metal
part of the gun firmly to the side of a grounded metal pail and use
the lowest possible fluid pressure during flushing.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards –
particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

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. Revi -
sar
con regularidad el funcionamiento del difusor . Seguir el pro-
cedimiento
de descarga de presión, dado más abajo, y des -
pués sacar la boquilla. Apuntar la pistola a un balde metálico,
sosteniéndola
bien firme contra él. Utilizando la presión más ba -
jo
posible, disparar la pistola. Si el fluido emitido no sale disperso
en un chorro irregular , reemplazar de inmediato el difusor .
Protector de la boquilla
SIEMPRE tener el protector de la boquilla colocado en la pistola
mientras se está pulverizando. Este protector llama la atención
contra el peligro de inyección y ayuda a reducir, pero no evita,
la
colocación accidental de los dedos o cualquier otra parte del
cuerpo cerca de la boquilla.
Seguridad de la boquilla pulverizadora
Tener mucho cuidado al limpiar o cambiar las boquillas. Si llega -
ra

SEGURIDAD EN EL USO DE LAS MANGUERAS
El fluido que escapa a alta presión por las mangueras puede ser
muy peligroso. Si en la manguera se desarrola un escape, una
rotura o rajadura debido a cualquier tipo de desgaste, daño o
maltrato, el chorro a alta presión emitido por allí puede causar
una lesión por inyección u otras lesiones corporales graves o
daños
a la propiedad.
¡TODAS LAS MANGUERAS PARA FLUIDOS TIENEN QUE
TENER GUARDAS DE RESORTE EN AMBOS EXTREMOS!
Estas
protegen las mangueras contra dobleces o retorceduras
en los acoplamientos o cerca de ellos, los que podrían traducir -
se
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 revisarla
en busca de cortaduras, escapes, abrasión, cubierta abultada, o
acoplamientos sueltos o dañados. Si llegara a encontrarse cual -
quiera
de estas condiciones, reemplazar de inmediato la mangue -
ra.
NO intentar reacoplar una manguera de alta presión o enmen -
darla
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 MANGUE-
RAS.
No tirar de las mangueras para mover el equipo. No usar
fluidos o solventes que sean incompatibles con el tubo interno
y la cubierta de la manguera. NO exponer las mangueras a tem -
peraturas
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 esen -
cial para mantener conectado a tierra el sistema pulverizador.
Es
indispensable revisar la resistencia eléctrica máxima de las
mangueras de aire y de fluido por lo menos una vez a la semana.
Si la manguera no tiene una etiqueta en la cual se especifica la
resistencia eléctrica máximum, ponerse en contacto con el pro -
veedor o fabricante de la manguera para la información sobre
los
límites de resistencia. Usar un metro de resistencia en la ga -
ma
apropiada para comprobar la resistencia; si excede los lites
recomendados, reemplazarla de inmediato. Es muy arriesgado
tener una manguera sin puesta a tierra o con la puesta a tierra
en malas condiciones. Leer también la información sobre RIES-
GO DE INCENDIO O EXPLOSION
, más arriba.
PELIGRO DE INCENDIO O EXPLOSION
El flujo a alta velocidad del fluido al pasar por la bomba y mangue -
ra
crea electricidad estática. Si todas las partes del equipo pulve -
rizador
no tienen buena tierra, pueden ocurrir chispas, convirtién -
do al sistema en algo peligroso. También, pueden producirse
chispas
al enchufar o desenchufar el cordón eléctrico o al usar
un motor de gasolina. Estas chispas pueden inflamar los vapores
de los solventes y el chorro de fluido pulverizado, partículas de
polvo y otras sustancias inflamables, sea al aire libre o bajo techo,
lo que podría causar una explosión o incendio y graves lesiones
corporales y daños a la propiedad.
Si ocurre una chispa de electricidad estática o incluso un ligero
choque eléctrico mientras se usa el equipo, DEJAR DE PUL VE-
RIZAR
DE INMEDIA T O. Revisar todo el sistema en busca de una
tierra apropiado. No usar de nuevo el sistema hasta haber identifi -
cado
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 códi -
go

1. Pulverizadora: enchufar el cordón eléctrico, o cable extensor ,
cada
uno con un enchuf de tres patas en buen estado, a un
tomacorriente con puesta a tierra aporpiado. No usar un
adaptador.
T otos 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

SETUP
Connect Hose and Gun
Remove the plastic cap from the outlet tee, 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!
To avoid damaging the pressure control, which
may result in poor equipment performance and
component
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 shutoff 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
Fill Packing Nut/Wet Cup
Fill the packing nut/wet cup 1/3 full with throat seal liquid,
supplied. Keep the wet cup filled to help protect and pro -
long
the life of the pump’ s throat packings.
Check Electrical Service and Plug In
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 .
Be sure the ON/OFF switch is OFF .
Plug
the power supply cord into a grounded electrical out -
let that is at least 20 ft. (6 m) away from the spray area
to reduce the chance of a spark igniting the spray vapors.
Set Pressure Control
Turn the pressure control knob to the lowest setting.
Flush the Pump
An important part of the care and maintenance of your
sprayer
is proper flushing. Refer to page 9.
CAUTION
Never operate the sprayer without the drain valve
in
place. The drain valve is used to help relieve sys -
tem
pressure and to help prime the sprayer .
Do
not attach a spray hose to the drain valve; doing
so could result in costly damage to the pressure
control.

Prepare the Paint
Prepare the paint as instructed by the manufacturer . Re -
move
any skin that may have formed. Stir the paint to dis -
solve 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 evapo -
ration.
Do not add too much solvent as thin paint is hard
to control and doesn’t cover very well. Follow the paint
manufacturer’s
recommendations on thinning.
Prime the Sprayer
Close the drain valve. Don’t install the spray tip yet! Put
the suction tube into the paint container. Turn the pres-
sure
adjusting knob all the way counterclockwise to lower
the pressure setting. Disengage the gun safety latch.
Hold
a metal part of the gun firmly against and aimed into
a grounded metal waste container. 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. Re-
lease
the trigger and engage the 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 safety
latch
and trigger the gun to prime the hose as in -
structed
previously , under Prime the Sprayer .
Check
all fluid connections for leaks. If any are found, fol -
low the Pressure Relief Procedure, page 2, before
tightening
connections.

and the drain valve is closed.
4. Remove the spray tip from the gun.
5. Disengage the gun safety latch.
WARNING
To
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.
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

ADJUST THE SPRAY PATTERN
Increase the pressure adjusting knob setting just until
spray
from the gun is completely atomized. Use the low -
est
pressure necessary to get the desired results, which
helps prolong the life of your sprayer and minimizes paint
lost by overspray .
Test 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 1 1.
Cleaning and Clearing the Spray Tip
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 con -
tainer
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, engage the gun
safety latch 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 1 1.
WARNING
Clean
out the front of the spray tip frequently during daily
operation. First, follow the Pressure Relief Procedure
Warning page 11. Then use a solvent soaked brush to
clean
the spray tip and to keep build up from drying and
clogging the spray tip.
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 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 0072
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 produces uni -
form paint thickness. And spraying in a uniform 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 de -
pends
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

11

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 approaches
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. Other-
wise
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
Nearby objects. Move objects such as automobilies, pic -
nic tables, lawn furniture, etc. up–wind of the surface to
be sprayed. In the case of a nearby home, make a protec -
tive
barrier by hanging plastic between two long poles.
SHUTDOWN AND CARE
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
fluid
injection; splashing in the eyes or on the skin; in -
jury from moving parts or electric shock, always fol-
low this procedure whenever you shut of f the sprayer ,

overtighten! Overtightening may cause binding and ex-
cessive
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.
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 9.
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 .
For very short shutof f periods , leave the suction tube

fluid injection; splashing in the eyes or on the skin;
injury from moving parts or electric shock, always
follow the Pressure Relief Procedure Warning
on page 12 before continuing.
Removing the Pump
Flush the sprayer if possible.
Remove the hose clamps (87, 88) and move the drain
tube
(90) away from the pump. Unscrew and remove the
suction tube (52). Remove the adapter (50). See Fig 1.
Disconnect the hose (20) from the nipple (22). See Fig 1.
Push the retaining spring (55) up. Push out the pin (57).
Loosen the cylinder locknut (103) and unscrew the pump
(26) from the drive assembly (65).
See Disassembling the Pump , below .
Installing the Pump
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.
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.
Screw the pump cylinder completely into the drive as-
sembly;
you will feel some resistance from the packings.
Now turn the cylinder back until the outlet nipple (22)
faces
back. Screw the hose (20) onto the nipple; tighten
it securely. To 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).
Reassemble remaining parts reverse from disassembly .
NOTE: Use
Repair Kit No. 820–549 to repair the pump.
See page 23. 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
Remove the pump from the sprayer as described above.
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 2 and 4. Remove
the ball guide (40), the stop pin (39) and the ball (28).
Clean
and inspect the parts for wear or damage.
NOTE: Test 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.

Unscrew
and remove the packing nut (38). Using a rub -
ber mallet, tap the piston rod (47) down and pull it out
through
the bottom of the cylinder (46). See Fig 3 and 4.
Remove the glands (34 & 37) and the packings (35 & 36).
Clean and inspect the piston rod and the inside of the cyl -
inder for nicks, scratches or scoring which could cause
leaking
or premature wear of the packings.
Clamp the flats of the piston rod in a vise. Use a wrench
to loosen the nut (33) and unscrew the piston 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
When assembling the pump, coat the packings, the pis -
ton
rod and the inside of the cylinder with oil.
When reassembling the piston, install the new glands
and
packings in the correct order , alternating the leather
and plastic packings. See Fig 3. The “V” of the packings
must face up against the fluid pressure. See Fig 4. T ight-
en the nut (33) to 10.5 in–lb (1.2 N.m) to seat the pack-
ings,
then back of f the nut and hand tighten it.
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 (0.11–0.22
N.m) torque. Tighten 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.
Install the throat packings, glands and packing nut, leav -
ing the packing nut loose. The “V” of the packings must
face down against the fluid pressure. Alternate the plastic
packings (36) and the leather packings (35). See Fig 3.
Insert the piston rod (47) through the bottom of the pump
cylinder (46).
Assemble and install the intake valve (48); torque it to
75–85
ft–lb (100–1 15 N.m). T ighten the packing nut (38)
just enough to stop leakage––no tighter .

PRESSURE CONTROL AND CIRCUIT BOARD
WARNING
To
reduce the risk of serious bodily injury , including
fluid injection; splashing in the eyes or on the skin;
injury from moving parts or electric shock, always
follow the Pressure Relief Procedure Warning
on
page 12 before continuing.
NOTE: A circuit board (81) is not included with a new
pressure control (74). However, it is included
with
a new motor and it can be ordered separate -
ly.
Be sure to order the correct circuit board. See
the
application information on page 22.
Do not allow the fittings (A) to move when removing
the elbow (93) or tee (94) from the pressure con-
trol,
to avoid altering the factory setting of the pres -
sure
control or damaging the pressure control.
CAUTION
Circuit Board Removal
1. Remove the pressure control cover (79). Pull the cir -
cuit
board (81) out carefully , just enough to reach the
wire terminals. Disconnect the leads. Remove the
board.

PRESSURE CONTROL CALIBRA TION
USE EXTREME CAUTION WHEN PERFORMING THIS CALIBRA TION PROCEDURE to reduce the risk of an
injection
injury or other serious bodily injury which can result from component rupture, electric shock, fire, explo -
sion,
or moving parts.
This procedure sets the sprayer to 2750 psi (190 bar)
MAXIMUM WORKING PRESSURE.
This procedure must be performed whenever micros -
witch
or pressure control assembly is removed and re -
installed
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 ex -
plosion.
It may also prevent the sprayer from obtaining
the maximum working pressure which would result in
poor sprayer performance.
NEVER try to increase the fluid outlet pressure by per -
forming these calibrations in any other way. Normal
operation
of the sprayer at higher pressures could re -
sult
in component rupture, fire or explosion. T o perform
this adjustment, however, the sprayer pressure must
be
temporarily increased above the normal working
pressure.
Use a new 50 foot (15.2 m) spray hose rated for 3000
psi (210 bar) MAXIMUM WORKING PRESSURE
when
performing this procedure. A used, under–rated
hose could develop a high pressure leak or rupture.

1. Relieve pressure. See page 12.
2. Plumb the pressure control with additional parts as
shown in Fig 11. Connect the needle valve to the
open
end of the hose.
NOTE: See Fig 12 for the following procedure.
3. Remove the cover (79) and plug (123).
4. Open the needle valve slightly. Turn the pressure
control
knob (A) to the minimum setting.
5. Plug in and turn on the sprayer. Increase the pres-
sure setting just enough to start the sprayer. Prime
the
hose and purge all air from the system.
6. Open the needle valve a little more––enough to allow
the pump to run continuously––and turn the pressure
control knob to maximum. Now, very slowly start to
close
the needle valve, but don’t close it all the way .
Observe the pressure at which the pump stalls,
which
should be approximately 2750 psi (190 bar) .
NOTE: The slower the pressure is raised, the easier it is
to note the exact stall pressure. Closing the
needle
valve quickly causes the pressure to rise
too fast which gives a false reading.
If the pressure is lower than 2750 psi (190 bar) :
Unplug the sprayer. Relieve pressure. Insert the
socket wrench through the plug hole and untighten
the
pressure adjustment nut 1/8 turn or less, then re -
peat
steps 5 and 6.
If the pressure is higher than 2750 psi (190 bar) :
Unplug the sprayer. Relieve pressure. Insert the
socket
wrench through the plug hole and tighten the
pressure adjustment nut 1/8 turn or less and repeat
steps 5 and 6. Repeat this procedure until the proper
stall pressure is obtained.
7. Now check to see at what pressure the sprayer starts
to run again after it stalls. Plug in the sprayer , turn it
on, close the needle valve, and set the pressure at
maximum.
Allow the sprayer to run until it stalls.
8. Open the needle valve very slowly while observing
the pressure gauge. Check to see if the pressure
drops to approximately 2350 psi (164 bar) before
starting
again.
If the pressure is not 2350 psi (164 bar) :
Shut off and unplug the sprayer, but do not relieve
pressure. Turn the differential wheel (D) just one
notch
and repeat Steps 5 and 6. Check the pressure
drop again and repeat if necessary .
NOTE:
Always recheck the stall pressure (steps 5, 6) if
the dif ferential wheel was adjusted.
9. Follow the Pressure Relief Procedure W arning on
page 12. Flush the water out with mineral spirits. Re -
lieve pressure again. Install the plug (123) and cover
(79). Remove the test equipment.
