WARNING

HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.

FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.

Read and understand all instruction manuals before operating equipment.

FLUID INJECTION HAZARD

General Safetv

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

Se 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.

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.

Be sure equipment safety devices are operating properly

before each use.

Medical Treatment

If any fluid appears to penetrate your skin, get

EMERGENCY MEDICAL CARE AT ONCE.

DO NOT TREAT AS A SIMPLE CUT.

Tell the doctor exactly what fluid was injected. For treatment
instructions, have your doctor call the

NATIONAL POISON CENTER NETWORK

(4121661-6666

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 i‘ip 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 Pro­cedure 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. (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 grounded metal pail, and trigger the gun to relieve
pressure. (6) Engage the gun safety latch. 17) Open the drain valve, having a container ready to catch the drainage. (8) Leave the
drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen
completely. Now clear the tip or hose.

EQUIPMENT MISUSE HAZAF?D

General Safety

Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible
chemicals and materials, or using worn or damaged parts, can
cause them to rupture and result in injection or other serious
bodily injury, fire, explosion or property damage.

NEVER alter or modify any part of this equipment; doing so

could cause it to malfunction.

CHECK all spray equipment regularly and repair or replace

worn or damaged parts immediately.

System Pressure

This sprayer can develop 3&N psi (207 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 Darts shown in the Technical Data on
ihe back cover. Always’ read the fluid and solvent manufac­turer’s literature before using them in this sprayer.

HOSE SAFETY

High pressure fluid in the hoses can be very dangerous. If the
hose develops a pinhole leak, split or rupture due to any kind
of wear, damage or misuse, the high pressure spray emitted
from it can cause an injection injury or other serious bodily in-

jury or property damage.

ALL FLUID HOSES MUST HAVE SPRING GUARDS!

The
spring guards help protect the hose from kinks or bends at or
close to the coupling which can result in hose rupture.

TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.

NEVER use a damaged hose. Before each use, check entire
hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose or mend it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.

HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Do not use fluids or solvents which
are not compatibiewith the inner tube and cover of the hose.

DO NOT exoose Grace hose to temperatures above 160°F
W”C) or beiow -40°F WOW.

Hose Groundin Continuity

Proper hose groun mg 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 im­mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also read

FIRE OR EXPLOSION

HAZARD.

FIRE OR EXPLOSlON HAZARD

Static electricity is created by the high velocity flow of fluid

through the pump and hose. If every part of the spray equip-

ment is not properly grounded, sparking may occur, and the
system may become hazardous. Sparking may also occur
when plugging in or unplugging a power supply cord. Sparks

can ignite fumes from solvents and the fluid being sprayed,

dust particles and other flammable substances, whether you

are spraying indoors or outdoors, and can cause a fire or ex-

plosion and serious bodily injury and property damage.

Always plug the sprayer into an outlet at least 20 feet (6 m)

away from the sprayer and the spray area. Do not plug in or

unplug any power supply cords in the spray area when there is

any chance of igniting fumes still in the air.

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.

Groundinit . To reduce t e nsk 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 in­structions 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 m) 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 reliev­ing pressure, always hold a metal part of the gun firmly to
the side of a grounded metal pail, then trigger the gun.

MOVUVG

PARTS

HAZARD

Moving parts can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting or
operating the sprayer. Unplug the sprayer and relieve pressure
before checking or servicing the sprayer to prevent it from
starting accidentally.

y causen la inyecci6n de fluid0 u otras lesiones corporales

graves, incendio, explosi6n o dafion 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 daiiadas o desgastadas.

Presi6n del sistema

Esta pulverizadora puede desarrollar 207 barias (3000 psi) de
PRESION DE TRABAJO MAXIMA. Asegurar que todo el
equip0 pulverizador y sus accesorios tienen la capacidad para
aguantar la presi6n mhxima de trabajo de esta pulverizadora.
NO exceder la presibn mBxima de trabajo de ninglin com­ponente o accesorio de este sistema.

Compatibilidad de fluid0

ASEGURAR que todos 10s fluidos y solventes usados son
quimicamente compatibles con las piezas mojadas ilustradas
en la hoja de datos tknicos en la contratapa. Siempre leer las
instrucciones del fabricante del fluid0 y solvente antes de
usarlos en esta pulverizadora.

SEGURIDAD 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 pe­queiio, una rotura o rajadura debido a cualquier tipo de
desgaste, daiio o maltrato, el chorro a alta presi6n emitido por
alli puede causar una lesi6n por inyecci6n u otras lesiones cor­porales graves o dafion a la propiedad.

iTODAS LAS MANGUERAS PARA FLUIDOS TIENEN
QUE TENER GUARDAS DE RESORTE!

Estas protegen las

mangueras contra dobleces o retorceduras en 10s acoplamien-

tos 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 presi6n.

NUNCA usar una manguera que est& daRada. Siempre,
revisarla en busca de cortaduras, escapes, abrasibn, cubierta
abultada, o acoplamientos sueltos o dafiados. Si llegara a en­contrarse cualquiera de estas condiciones, reemplazar de in­mediato 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 62°C (180°F) o bajo

-4OT (-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 elktrica
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 tam­bikn la informaci6n sobre

RIESGO DE INCENDIO 0 EXPLO-

SION,

m8s arriba.

PELIGRO DE INCENDIO 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. Tambik,
pueden producirse chispas al enchufar o desenchufar el cor­d6n elkctrico. 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 daiios a la propiedad. Enchufar siempre
la pulverizadora a un tomacorriente que se encuentre a por lo
menos 6 m (20 pies) de la mBquina y del drea que se va a
rociar. No enchufar o desenchufar ningtin cordbn elktrico en
el lugar donde se estB rociando cuando todavia exista la
posibilidad de que queden vapores inflamables en el aire.

Puesta a tierra

Para reducir el riesgo de chispas esthticas, 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.

MAIN FLUID HOSE

WHIP HOSE

Your new UltraTM 433 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.

Displacement Pump
The positive displacement, volume-balanced pump pro­vides 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 III 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.

1. Connect Hose and Gun (Refer

to

Fig 1.1

a. Remove the plastic cap plug from the filter

outlet nipple and screw the 56 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
plastic cap plug from the secondary hose ball valve
and attach an accessory hose and gun.

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.)
Fill the packing nut/wet-cup l/3 full with Grace
Throat Seal Liquid ITSL), supplied.

4. Check Electrical Service
a.

Be sure the electrical service is 120 V,

66 HzAC, 15 Amp (minimum) and that the

outlet you use is properly grounded.

b. Use an extension cord which has 3 wires of a

minimum 12 gauge size, and a maximum of

156 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.

6. Flush the pump to remove the No. 10 motor oil
which was left in to protect pump parts after fac­tory testing.
a.

Before using water-base paint, flush with
mineral spirits followed by soapy water, and
then a clean water flush.

b. Before using oil-base paint, flush with mineral

spirits only.

c. See “Flushing Guidelines” on page 12 for

flushing procedure.

Prepare the paint according to the manufacturer’s
recommendations.

a. Remove any skin that may have formed.

b. Stir the paint to dissolve pigments.

c. Strain the paint through a fine nylon mesh bag

(available at most paint dealers) to remove par­ticles 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 pro­ceed as in Step If, above.

g. Check all fluid connections for leaks. If any are

found, follow the Pressure Relief Procedure
Warning, above, before tightening connec­tions.

2. Install the Spray Tip and Tip Guard
(Refer to Fig 5.)
a. Be sure the gun safety latch is engaged.

b. Unscrew the retaining nut from the gun.

d. Tighten the retaining nut by hand until snug.

e. Use a wrench to tighten the retaining nut about

l/8 to l/6 turn.

I CAUTloN 1

Overtightening the retarnrng nut will damage the
seat gasket and result in leakage.

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.

spraying, engage the gun safety latch immediate­ly, then follow the procedure in Steps 4a-4e,

I

below,

I

I

NEVER wipe off build up around the spray tip until
pressure is fully relieved and the gun safety latch is
engaged.

I

a. Clean the front of the tip frequently during the

day’s operation. First, follow the Pressure

Relief Procedure Warning in on page 10.
Then use a solvent-soaked brush to keep
material from building up and clogging the tip.

b. If the spray tip does clog, release the gun trig-

ger, engage the gun safety, and rotate the
spray tip handle 160°. 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 stillclogged, 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 i : ; ‘.‘.I.:, ;A’:’

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 material buildup on the
piston rod and premature wear of packings. The
packing nut should be tight enough to stop
leakage, but no tighter. Overtightening may cause
binding and excessive packing wear. Use a 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 10.)

1. Unscrew the intake valve (222) from the cylinder

(216). Remove the gasket (206). ball guide (215),
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 (205),

packings (208, 217) and glands (213, 220).

1.

2.

Use Repair Kit No. 218-033 to repair the displace­ment pump. Reference number in parentheses with
an asterisk, for exampe, (210*), show the parts in­cluded in thekit. Use all the new parts, even if the
old ones still look good as the old parts cause the

new ones to wear prematurely.

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. Incor­rect installation damages the packings and results
in the pump leaking.

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 W!O”), packings (217*, 208”) and

male gland (213”) onto the piston valve. See

Figures 11 Et 12.

5.

Tighten the packing retaining nut (214) onto the

piston valve (224) and torque to 3 to 4 in-lb (0.34 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.

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.

8. Stack the male gland (211*), packings (218*, 209”)
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
the 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 (206”) 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 the 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 nip-

ple (46) 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-m)-with a 2 in. open-end wrench
and a light hammer.

WARNING

Be sure the retaining spring (35) 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 beanng housrng (27) WIII be per-

manently damaged. Be sure to tighten the locknut

firmlv.

CAUTION

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.

Packing Repair Kit 218-033. Replace them

when replacing the packings, and/or when

they have been worn to a minimum of g/16”
on the longest side.

1.

Remove the motor screws (1121, washers (113) and

cover (14). See Fig 14.

2.

Remove the screws (l-l), inspection covers (J) and

gaskets (K) on each side of the motor. See Fig 14.

3.

Loosen the brush lead terminal screw and remove
the lead.

4.

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.

5.

Remove and discard the brush.

6.

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 as 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.

WARNING

Do not touch the brushes, leads, springs or brush
holders while the sprayer is plugged in to avoid

electric shock and possible serious bodily injury.

CAUTION

Do not run the sprayer dry for more than 30
seconds while checking the brushes to avoid
damaging the displacement pump.
