WARNINGS
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating the equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generates very high fluid pressure. Spray
from the gun, leaks or ruptured components can inject fluid
through your skin and into your body , and cause extremely
serious bodily injury
, including the need for amputation. Also,
fluid injected or splashed into the eyes or on the skin can
cause serious damage.
NEVER point the spray gun at any one or at any part of the
body . NEVER put your hand or fingers over the spray tip.
NEVER try to “blow back” paint; this is NOT an air spray sys-
tem.
ALWA
YS have the tip guard in place on the spray gun when
spraying.
ALWA
YS 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 be -
fore 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 re-
constructive
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
injection when the tip is not installed. Check dif fuser operation
regularly . Follow the PRESSURE RELIEF PROCEDURE,
below
, then remove the spray tip. Aim the gun into a metal
pail, holding the gun firmly to the pail. Using the lowest possi -
ble 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 acciden -
tally 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
immediately . AL WA YS follow the PRESSURE RELIEF PRO-
CEDURE,
below, and then remove the spray tip to clean it.
NEVER wipe of f build–up around the spray tip until the pres -
sure is fully relieves and the gun safety is engaged.
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious bodily injury , including fluid injec -
tion, 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 changing spray tips, and whenever you stop
spraying.
1.
Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3.
Unplug the power supply cord.
4. Disengage the gun safety latch. Hold a metal part of the gun
firmly to the side of a grounded metal pail, and trigger the gun
to relieve pressure.
5. Engage the gun safety latch.
6. Open the pressure drain valve, having a container ready to
catch
the drainage. Leave the valve open until you are ready
to spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved after fol -
lowing the steps above, VERY SLOWL Y loosen the tip guard
retaining nut or hose end coupling to relieve pressure gradu -
ally
, 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 spray -
er
, 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, ex -
plosion or property damage.
NEVER alter or modify any part of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately .
Always wear protective eyewear , gloves, clothing and respira -
tor as recommended by the fluid and solvent manufacturer .
System Pressure
This sprayer can develop 3000 psi (210 bar) MAXIMUM
WORKING PRESSURE.
Be sure all spray equipment and
accessories used are rated to withstand the this pressure. DO
NOT exceed the maximum working pressure of any compo -
nent 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
43. Consult your chemical supplier to ensure compatibility .
Do not use 1,1,1-trichloroethane, methylene chloride, other
halogenated hydrocarbon solvents or fluids containing such
solvents in this equipment, which contains aluminum and/or
zinc parts. Such use could result in a serious chemical reac -
tion, with the possibility of explosion, which could cause
death, serious bodily injury and/or substantial property dam -
age.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear ,
damage or misuse, the high pressure spray emitted from it
can cause a fluid injection injury or other serious bodily injury
or property damage.
ALL FLUID HOSES MUST HAVE STRAIN RELIEFS ON
BOTH ENDS!
The strain reliefs help protect the hose from
kinks or bends at or close to the coupling which can result in
hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the
entire hose for cuts, leaks, abrasion, bulging cover , or dam -
age or movement of the hose couplings. If any of these condi -
tions exist, replace the hose immediately . DO NOT try to
recouple high pressure hose or mend it with tape or any other
device. A repaired hose cannot contain the high pressure
fluid.
HANDLE AND ROUTE HOSES CAREFULLY
. Do not pull on
hoses to move equipment. 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 tem -
peratures 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 resis
-
tance, contact the hose supplier or manufacturer for the maxi -
mum resistance limits. Use a resistance meter in the appropri -
ate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace it imme -
diately
. An ungrounded or poorly grounded hose can make
your system hazardous. Also read FIRE OR EXPLOSION
HAZARD, below.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the
pump and hose. If every part of the spray equipment is not
properly grounded, sparking may occur , and the system may
become hazardous. Sparking may also occur when plugging
in or unplugging a power supply cord or using a gasoline en -
gine. Sparks can ignite fumes from solvents and the fluid be -
ing 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 dam -
age. Always plug the sprayer into an outlet at least 20 feet (6
m) away from the sprayer and the spray area. Do not plug in
or unplug any power supply cords in the spray area when
there is any chance of igniting fumes still in the air .
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING IMMEDI-
ATELY
. Check the entire system for proper grounding. Do not
use the system again until the problem has been identified
and corrected.
Grounding
T o reduce the risk of static sparking, ground the sprayer and
all other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding in -
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1. Sprayer: plug the power supply cord, or extension cord – each
equipped with an undamaged, three–prong plug, into a prop -
erly grounded outlet. Do not use an adapter . All extension
cords
must have three wires and be rated for 15 Amps.
2. Fluid hoses: use only grounded hoses with a maximum  f 500
ft (150 m) combined hose length to ensure grounding 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
splashing by following the flushing procedure given on page
12 of this manual. Follow the PRESSURE RELIEF PROCE-
DURE
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.

PELIGRO
POR MAL USO DEL EQUIPO
Seguridad general
Cualquier mal uso del equipo pulverizador o los accesorios,
tal como sobre presurización, modificación de piezas, uso de
materiales y productos químicos incompatibles, o utilización
de piezas dañadas o desgastadas, puede hacen que se
rompan y causen la inyección de fluido u otras lesiones cor -
porales graves, incendio, explosión o daños a la propiedad.
Siempre usar gafas, guantes, vestimentas protectoras y un
respiradero, tal como recomiendan los fabricantes del fluido y
del solvente.
Presión del sistema
Esta pulverizadora puede desarrollar 210 barías (3000 psi) de
PRESION DE TRABAJO MAXIMA. Asegurar que todo el
equipo pulverizador y sus accesorios tienen la capacidad pa -
ra aguantar la presión máxima de trabajo de ningún compo -
nente o accesorio de este sistema.
Compatibilidad de fluido
Siempre leer las instrucciones del fabricante del fluido y
solvente antes de usarlos en esta pulverizadora.
SEGURIDAD EN EL USO DE LAS MANGUERAS
El fluido que escapa a alta presión por las mangueras puede
ser muy peligroso. Si en la manguera se desarrola un escape,
una rotura o rajadura debido a cualquier tipo de desgaste,
daño o maltrato, el chorro a alta presión emitido por allí puede
causar una lesión por inyección u otras lesiones corporales
graves o daños a la propiedad.
¡TODAS LAS MANGUERAS PARA FLUIDOS TIENEN QUE
TENER GUARDAS DE RESORTE EN AMBOS EXTREMOS!
Estas protegen las mangueras contra dobleces o retorcedu -
ras en los acoplamientos o cerca de ellos, los que podrían
traducirse en roturas de la manguera.
Antes de usarlas, APRET AR bien firmes todas las conexio -
nes. 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 presión
o enmendarla con cinta adhesiva u otro material similar . Una
manguera que ha sido remendada no aguante el fluido al alta
presión.
MANEJAR
Y P ASAR 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 man -
gueras 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 pulveri -
zador
. Es indispensable revisar la resistencia eléctrica máxi -
ma de las mangueras de aire y de fluido por lo menos una
vez a la semana. Si la manguera no tiene una etiqueta en la
cual se especifica la resistencia eléctrica máximum, ponerse
en contacto con el proveedor o fabricante de la manguera
para la información sobre los límites de resistencia. Usar un
metro de resistencia en la gama apropiada para comprobar la
resistencia; si excede los lites recomendados, reemplazarla
de inmediato. Es muy arriesgado tener una manguera sin
puesta a tierra o con la puesta a tierra en malas condiciones.
Leer también la información sobre RIESGO DE INCENDIO O
EXPLOSION
, más arriba.
PELIGRO DE INCENDIO O EXPLOSION
El flujo a alta velocidad del fluido al pasar por la bomba y
manguera crea electricidad estática. Si todas las partes del
equipo pulverizador no tienen buena tierra, pueden ocurrir
chispas, convirtiéndo al sistema en algo peligroso. T ambién,
pueden producirse chispas al enchufar o desenchufar el cor -
dón eléctrico o al usar un motor de gasolina. Estas chispas
pueden inflamar los vapores de los solventes y el chorro de
fluido pulverizado, partículas de polvo y otras sustancias
inflamables, sea al aire libre o bajo techo, lo que podría
causar una explosión o incendio y graves lesiones corporales
y daños a la propiedad. Enchufar siempre la pulveriszadora a
un tomacorriente que se encuentre a por lo menos 6 m (20
pies) de la máquina y del área que se va a rociar . No enchu -
far o desenchufar ningún cordón eléctrico en el lugar donde
se está rociando cuando todavía exista la posibilidad de que
queden vapores inflamables en el aire.
Si ocurre una chispa de electricidad estática o incluso un lige -
ro choque eléctrico mientras se usa el equipo, DEJAR DE
PULVERIZAR DE INMEDIAT O. 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 código eléctrico de la localidad para las instrucciones
sobre las conexiones a tierra exigidas para la zona y tipo de
equipo. ASEGURAR de conectar a tierra todo este equipo
pulverizador:
1.
Pulverizadora: enchufar el cordón eléctrico, o cable estensor ,
cada
uno con un enchuf de tres patas en buen estado, a un
tomacorriente con puesta a tierra apropiado. No usar un
adaptador.
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
también
al párrafo sobre continuidad a tierra de la mangue -
ra.
3.
Pistola: hacer la puesta a tierra conectándola a una mangue -
ra
de fluido y pulverizadora bien conectadas a tierra.
4. Suministrar un recipiente: de acuerdo al código local. Usar
solamente baldes de metal, que sean conductivos. No
colocar
el balde en una superficie no conductiva, como papel
o cartón, que interrumpe la continuidad a tierra.
5. Objeto que se está rociando: de conformidad con el código
local.
6.
Todos los baldes de solvente usados durante el lavado, de
conformidad
con el código local.
7. Para mantener la continuidad a tierra durante el lavado o des -
carga de presión, siempre apoyar una parte metálica de la
pistola bien firme contra el costado de
balde de metal ,
después apretar el gatillo.
Seguridad durante el lavado
Para reducir el riesgo de que se inyecte o salpique fluido en
la piel, o que ocurra una descarga de electricidad estática,
siempre seguir las INSTRUCCIONES PARA EL LAVADO,
dadas en la página 12. Seguir el procedimiento de descar -
ga de presión en la página 6, y quitar la boquilla de metal y
usar le presión más baja posible de fluido durante el lavado.

SETUP
To reduce the risk of serious bodily injury
caused by static sparking, fluid injection or
over–pressurization and rupture of the hose
or gun:
1. Ground the sprayer and all objects being
sprayed. Read
FIRE OR EXPLOSION
HAZARD on page 3.
2. Do not operate the spray gun without a
tip guard in place.
3. Be sure all parts added to the sprayer
are rated for at least 3000 psi (190 bar)
Maximum Working Pressure.
WARNING
To avoid damaging the pressure control, fol-
low these precautions.
1. Always use flexible, grounded hose at
least 50 feet (15.2 m) long.
2. Never use a wire braid hose; it is too rig-
id to act as a pulsation dampener.
3. Never install any shutoff device between
the fluid filter and the first 50 feet (15 m)
of hose. See Fig 1.
CAUTION
1. Connect a 50 foot spray hose and a gun to
the 1/4 npsm(m) fluid outlet nipple. For
more flexible gun movement, install a 3 foot
(0.9 m), 3/16 inch ID diameter hose between
the gun and main spray hose.
DO NOT use thread sealant on the hose and
gun connections. DO NOT install the spray tip
until the system is primed.
2. Fill the packing nut/wet–cup 1/3 full with
Throat Seal Liquid, supplied. Keep it filled to
help extend the life of the packings and the
pump.
3. Check the electrical service. It must be
120 VAC, 60 Hz, 15 Amp (minimum). The elec-
trical outlet must be properly grounded.
DO NOT remove the grounding prong of the
plug, and do not use an adapter.
Extension cords up to 100 feet (30 m) of 3
wire, 12 gauge (minimum) can be used.
Longer lengths may affect sprayer
performance. Use more spray hose to reach
the spray area, if needed.
4. Plug the power supply cord into an outlet
located at least 20 feet (6 m) from the spray
area. This reduces the chance of a spark ignit-
ing the spray vapors or dust particles.
5. Flush the pump to remove the lightweight test
oil which was left in it after factory testing. See
FLUSHING GUIDELINES on page 12.
6. Prepare the paint according to the instruc-
tions on the paint can. Strain the paint through
a fine nylon mesh bag to remove particles that
could clog the spray tip.

your spray tip for cleaning clogs.
SHUTDOWN AND CARE
1. Check the packing nut/wet–cup daily.
Relieve pressure. Keep the wet–cup 1/3 full of
Throat Seal Liquid to help prevent fluid buildup
on the piston rod and premature wear of pack-
ings. Tighten the packing just enough to stop
leakage. Overtightening may cause binding
and excessive packing wear. See Fig 11–2.
2. Flush the sprayer at the end of each work
day and fill it with mineral spirits to help pre-
vent pump corrosion and freezing. See
FLUSHING GUIDELINES on page 12.
Never leave water or any paint in the sprayer
overnight to prevent pump corrosion and to
prevent the fluid from freezing in the pump
and pressure control which can cause loss of
pressure, stalling or serious sprayer damage.
Always use mineral spirits for the final flush,
relieve pressure, and leave the mineral spirits
in the sprayer.
CAUTION
3. For very short shutoff periods, leave the
suction tube in the paint, relieve pressure, un-
plug the sprayer, and clean the spray tip.
4. Coil the hose around the top of the shroud
and rest it on top of the hose rack when storing
it, even for overnight, to help protect the hose
from kinking or damage.
5. Secure the suction hose to the brackets on
the side of the cart.

FLUSHING GUIDELINES
When To Flush
NEVER leave water in the sprayer if there is
the slightest chance it could freeze. Flush out
the water with mineral spirits. If water freezes
in the pressure control tube, it prevents the
sprayer from being started and causes seri-
ous damage to the pressure control.
CAUTION
1.
New Sprayer . Flush out the test oil.
Before using water-base paint, flush with
mineral spirits, followed by a soapy water
flush, and then a clean water flush.
Before using oil-base paint, flush with miner-
al spirits, only.
2. Changing Colors. Flush with a compatible
solvent such as mineral spirits or water.
3. Changing from water-base to oil-base
paint. Flush with warm, soapy water, and then
flush with mineral spirits.
4. Changing from oil-base to water-base
paint. Flush with mineral spirits, followed by
warm, soapy water, and then a clean water
flush.
5. Storage. Flush, leave the pump, hose and gun
filled with mineral spirits. Shut off the sprayer
and open the pressure drain valve to relieve
pressure.
Water-base paint: Flush with water, and then
mineral spirits.
Oil-base paint: Flush with mineral spirits.
6. Startup after storage.
Before using water-base paint , flush with
soapy water, and then with clean water.
When using oil-based paint, with the paint to
be sprayed.
How To Flush
1. Relieve pressure. See page 9.

APPLICATION METHODS
Hold the gun perpendicular to the surface. Keep
the gun at an even 12 to 14 in. (300–356 mm)
from the surface you are spraying. See Fig 13–1.
Begin moving the gun horizontally at a steady rate.
Start the spray stroke off the target surface and
pull the trigger as the gun is moving. Then, while
the gun is still moving, and as you approach the
other edge of the surface, release the trigger. This
method avoids excess paint buildup at the end of
each stroke.
Fig 13–1
RIGHT
WRONG
Move the gun at a speed that provides a full, wet
coating to be applied without runs or sags. Lap
each stroke 50% over the previous stroke to pro-
duce a uniform paint thickness. Spray in a uniform
pattern from right to left and then left to right for a
professional finish. See Fig 13–2.
Fig 13–2
OVERLAP EACH STROKE 50%
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 needed for
good results. This prolongs the life of your sprayer
and reduces paint lost by overspray.
For interior corners aim the gun toward the center
of the corner to be sprayed. By dividing the spray
pattern this way, the edges on both sides are
sprayed evenly. See Fig 13–3.
Fig 13–3
If there is a wind, angle the spray pattern into the
wind to minimize drifting. Paint from the ground to
the roof.
Shrubs. Tie back shrubs with rope and stakes.
Cover them with a dropcloth as the painter ap-
proaches the area. Remove the dropcloth as soon
as the area is painted to prevent damage.
Concrete walks. If the walkways will be walked on,
cover them with a canvas dropcloth to avoid slipp-
ing. Otherwise a plastic cloth can be used.
Electrical outlets and lamps. Protect electrical out-
lets with masking tape. Cover lamps with plastic
bags secured with masking tape.
Nearby objects. Move portable objects upwind of
the surface to be sprayed. If there is a nearby
home, make a protective barrier by hanging plastic
dropcloths between two long poles.

When check is not OK refer to this column
Building circuit breaker opens
as soon as sprayer switch is
turned
on.
1. Check all electrical wiring for damaged insu-
lation, and all terminals for loose fit or dam-
age. Also check wires between pressure con -
trol and motor which are encased in conduit
(13f).
See page 32.
1. Repair or replace any damaged wiring or
terminals. Securely reconnect all wires.
2. Check for missing inspection plate gasket
(see page 23), bent terminal forks or other
metal to metal contact points which could
cause
a short.
2. Correct faulty conditions.
3. Check motor armature for shorts. Use an ar -
mature tester (growler) or perform spin test.
See page 20. Inspect windings for burns.
3. Replace motor . See page 32.
4. Check bridge (308) by substituting with a
good bridge or by performing bridge test. See
page 21.
CAUTION: Do not check bridge until arma-
ture is determined to be good. A bad armature
will immediately burn out a good bridge.
4. Replace bridge. See page 25.
1. Check ‘Basic Electrical Problems’ on page
14.
2. Check ON/OFF switch (302) See page 24. Be
sure the sprayer is unplugged! Disconnect
wires
from switch. Check switch with ohmme -
ter. The reading should be infinity with the ON/
OFF switch OFF , and zero with the switch ON.
CAUTION: A short in the motor circuit burns
the bridge out immediately , which usually
causes the ON/OFF switch to fail in the closed
mode.
2. Replace ON/OFF switch. See page 24.
Sprayer circuit breaker opens
after sprayer operates for 5 to
10
minutes.
1. Check electrical supply with volt meter . Meter
should read 105 to 125 V AC. 1.
If voltage is too high, do not operate
sprayer until corrected.
2. Check tightness of pump packing nut. Over-
tightening tightens packings on rod, restricts
pump action, and damages packings.
2. Loosen packing nut. Check for leaking
around throat. Replace pump packings, if
necessary. See page 34.
3. Check maximum working pressure adjust-
ment. 3. Perform
pressure control adjustment. See

CAUTION
Any short in any part of the
motor power circuit, which is
connected to the output side
of the bridge, will cause the
bridge to burn out immedi-
ately.
Correctly diagnose and
repair all shorts before check -
ing
and replacing bridge.
