SAFETY PRECAUTIONS
This manual contains information which must be read and understood before using the equipment. When you come to an
area which has one of the following symbols, pay particular attention and make certain to heed the safeguard.
WARNING
Important safety information indicates a hazard which may cause serious injury or loss of life.
CAUTION
Important information that tells how to prevent damage to equipment or how to avoid causes of minor injuries.
Note: Gives important information which should be given special attention.
IMPORTANT
EXTENSION CORD SELECTION
If an extension cord is used, make sure it is of the three-conductor type with NEMA connectors so a continuous grounding circuit is
provided from tool to power circuit receptacle. Also, be sure that the conductor size is large enough to prevent excessive voltage drop
which will cause loss of power. A table of recommended extension cord sizes will be found below.
For nameplate ampere ratings which are between those given, use the extension cord recommended for the NEXT HIGHER ampere
rating.
If an extension cord is to be used outdoors it must be marked with the suffix W-A following the cord type designation. For example —
SJTW-A to indicate it is acceptable for outdoor use.

GENERAL DESCRIPTION
Be sure to read the IMPORTANT SAFETY INFORMA-
TION on pages 3 thru 6 before using this sprayer.
Your SprayTECH sprayer is a powerful, easy to operate
and easy to service machine. Since it operates on the
airless principle, no air compressor is needed.
Power is supplied by a 3/4 horsepower, TEFC electric
motor. The flow rate is 0 to .50 gallons a minute. The
pressure is adjustable from 0 to 3000 pounds per square
inch.
COMPONENT FUNCTIONS
See Figure 1 for component locations.
Power for the sprayer is supplied by a 3/4 horsepower,
TEFC electric motor (see Figure 1). It is located at the rear
ofthesprayerandisconnectedtothehydraulicpump.The
motorisfurnishedwitha3-wireelectriccord.Thethirdwire

wiregroundedelectricaloutlet.Donotuse2-wireextension
cords. Shorter extension cords will assure maximum
electricalpowerforproperoperation,usemorepaint hose,
not more extension cords. Refer to page 3 for extension
cord selection.
Cords and extension cords should be protected from
vehicletrafficandsharpcuttingedgesorobjects.Anyworn
or damaged cords should be replaced promptly.
The motor has an automatic overload protective switch.
This switch disconnects the motor from electrical supply if
overload occurs. The motor can be started again after 5
minutes. The cause of the overload should be corrected
before restarting.
Themotor should always be kept clean anddry. Paint acts
asaninsulator.Therefore,toomuchpainton themotor will
cause it to overheat.
ON-OFF SWITCH
The ON-OFF switch is located on the side of the electric
motor (see Figure 1).

The paint pump is located below the hydraulic pump (see
Figure 1). The two pumps are bolted together by four
socket head capscrews. The diaphragm separates the
pumps. The paint pump operates as follows: The piston in
the hydraulic pump forces hydraulic oil toward and away
from the diaphragm. This action moves the diaphragm up
and down. Diaphragm movement forces paint through the
spray gun at high pressure.
DIAPHRAGM
The diaphragm is the heart of the sprayer. In addition to
pumping paint, it also serves as a gasket between the
hydraulic pump and paint pump. As such, it prevents the
paint and oil from mixing. The sprayer operates at 1725
strokes per minute. This means that the diaphragm forces
a “gulp” of paint out of the spray gun 1725 times every
minute.
An insert fits in the inlet hole on the underside of the paint
pump. This insert reduces wear by protecting the dia-
phragm from the metal edges of the inlet hole.
The diaphragm is made of flexible, tough plastic. It is not
harmed by common solvents.
NOTE
The diaphragm should be replaced whenever the paint
pumpis removed. Using the old diaphragm willresult in
limited diaphragm life and fluid leaks.
For the hydraulic pump location, see Figure 1. It operates
asfollows: The electric motor is connectedtotheeccentric
bearing, which is inside the hydraulic pump. The piston
restson the bearing. The movement ofthebearingcauses
the piston to move up and down. When the trigger on the
gunispulled back,thisactionmovesthe pumpdiaphragm.
Diaphragm movement forces the paint through the outlet
valveandoutthepainthoseandspraygun.Thepaintgoes
throughthespraygunathighpressure,causingittobreak-
up (atomize) into fine particles. This gives a smooth and
even paint coating. Pressure and delivery rate are regu-
lated by the pressure control knob and spray tip size.
PRESSURE CONTROL KNOB
The pressure control knob controls the pressure control
valve.Itismanuallyoperated.Itislocatedonthefrontofthe
hydraulic pump near the bottom of the sprayer (see Figure
1). When the knob is turned cIockwise, more hydraulic
pressureisdirectedtowardthediaphragm.Whentheknob
is turned counterclockwise, less hydraulic pressure is
directed toward the diaphragm. The pressure control knob
regulates the pressure on the diaphragm from 0 PSI when
turned fully counterclockwise to 3000 PSI when turned
fully clockwise.
HYDRAULIC PUMP PAINT PUMP
INLET VALVE
Theinletvalveislocatedonbottomofthepaintpumpatthe
front of the sprayer (see Figure 1). The suction nut end of
thesuctiontubescrewsontothisvalve.Thevalveoperates
automatically. It controls the flow of paint from the paint
container into the paint pump. It does this by opening up
when the piston and diaphragm are on the downstroke,
allowing a “gulp” of paint to enter the paint pump. The inlet
valve then closes when the piston and diaphragm are on
the upstroke. This closing prevents paint from going back
through the inlet valve into the paint container (inlet valve
actsasacheckvalve).Instead,thepaintisdirectedoutthe
spray hose and spray gun by the outlet valve.
The inlet valve is a one-piece configuration. It contains a
device to dislodge a stuck valve by simply pushing the
plunger button on the side of the valve body.

of the paint block before starting the pump.
You can see that the inlet valve and outlet valve work in
harmony with the diaphragm and piston. As a" team" they

into the paint container. It will continue to do this until paint
comes through and it is manually switched to the

SUCTION SET
The complete suction set consists of (1) the suction tube
with a suction filter on one end and (2) the return tube (see
Figure1).Bothsuctionandreturntubearechemicalandoil
resistant. One end of the suction tube and one end of the
return tube screw onto the paint pump (see Figure 1).
These two fittings need to be tight enough to keep air from
being drawn in. The other two ends go in the paint con-
WARNING
DO NOT IMMERSE THE PAINT HOSE IN ANY
SOLVENTS.
The paint hose and the electric cord should always be
protected from vehicle traffic and sharp cutting edges
or objects. If the paint hose is cut, worn, or damaged it
mustbereplacedwithanotherhighpressuregrounded
hose.
The paint hose can develop leaks from wear, kinking,
abuse,etc.Aleakiscapableofinjectingspraymaterial
into the skin. Therefore, the paint hose should be
inspected periodically. Never repair a paint hose —
replace it with another high pressure grounded hose.
NOTE:
DO NOT USE THE SPRAYER UNLESS
THE SUCTION FILTER IS IN PLACE!
HIGH PRESSURE OUTLET FITTING
The high pressure outlet fitting is located on the front side
of the paint pump (see Figure 1). The paint hose is con-
nectedtoit.Theoutletfittingconnectionsmustbeverytight.
Otherwise, fluid will leak out the connections when pres-
sure builds up in the system.
PAINT HOSE
The high pressure paint hose (see Figure 1) has perma-
nently swaged fittings. It is grounded with a static conduc-
tor. This conductor serves to “drain off” any static charge,
preventing shock. The conductor is sandwiched between

PAINT STRAINING AND
THINNING
When a container of paint is exposed to the air for a period
of time, “skin” may form on top. This “skin” should be
removed. If necessary, the paint should be strained
through a strainer.
Under normal conditions, paints used with this airless
sprayer do not have to be thinned. However, it is possible
thatyoumayusepaintthatistoothicktobesprayed.Inthis
case you will have to thin the paint.
When thinning paint to spraying consistency (viscosity),
usetherightthinner—waterforlatexpaints,mineralspirits

same direction as the trigger (see Figure 6).
14. ADJUST PRESSURE — Adjust the pressure control
knobonthesprayertolowestpressureneededforgood
operation. Pull spray gun trigger back and spray a test
area to check spray pattern.
15. YOU ARE NOW READY TO SPRAY — See “SPRAY
PAINTING” for tips on how to spray.
You will also have to follow the above bleeding proce-
dure when you change hydraulic oil, if you remove the
paint pump or work on the hydraulic housing, or if the
sprayer loses prime due to rough handling.
1. CHECK TO BE SURE THE MOTOR SWITCH IS
OFF— play it safe.
2. LOCK SPRAY GUN—The spray gun will not spray
when the trigger lock is locked.
3. CHECK THE HYDRAULIC OIL— The sprayerer was
shipped with the proper amount of hydraulic oil in the
hydraulic pump. However, the oil should be checked
beforestarting. Lookatoillevelinoilfillport. Whenthe
unitislevel,oillevelshouldbeatbottomoffillport. Use
only hydraulaic oil part number 0088009 - 1 quart or
part number 0088010 - 1 gallon. Oil capacity is 19
ounces.
4. CHECK FITTINGS—Check to see that these fittings
are tight: inlet valve, return tube, outlet valve, outlet
fitting, high pressure airless hose, spray gun and allen
head paint pump screws.
NOTE
DONOT TIGHTEN PAINTPUMP SCREWS TOMORE

POUNDS)
5. TURNPRIMINGKNOBTO (PRIME)POSITION—A
will appear in the priming knob window. The sprayer
must be primed before it will spray.
6. Make sure the suction tube is immersed in paint.
7. PLUG ELECTRIC CORD INTO OUTLET— Electric
service must be 115 VAC, 60 Hz. REMEMBER: More
than 100 feet of extension cord is not recommended.
Use additional airless paint hose, not more electric
cord.
8. TURN THE MOTOR SWITCH ON.
9. PRIMETHE PUMP—Let the paint circulate until no air
bubbles show in the paint (aboutt 2-3 minutes). Turn
the pressure control valve at least 1/2 turn clockwise
from fully decreased postion to prime the pump with
paint.
10. BLEEDTHEAIR—Ifunitfailstoprimewhenstartedup,
it may be necessary to bleed (vent) the air out of the
hydraulic system. Bleed the air as follows:
A. Turn pressure control knob all the way counter-
clockwise, turnpriming knob to ,and let sprayer run
afew minutes. It is sometimes helpful to turn ON-OFF
switch ON and OFF to assit in bleeding.
B. Nowturn pressure control knobclockwise to prime

2. Avoid sharp bending and kinking of the paint hose. The
painthoseandelectriccordshouldbekeptclearoftraffic
and sharp cutting edges or objects.
3. Use the lowest pressure possible when spraying. Too
much pressure shortens equipment life. It also causes
faster than normal wear on the spray tip.
4. Determine the best spraying distance (distance from
spray tip on the spray gun to the work). If the spray gun
is held too close to the work, you will have paint buildup
thatwillcausesagsandruns.Ifthespraygunisheldtoo
far from the work, “fogging” will result.
The correct distance should be about 10 to 12 inches.
Keep this distance for the entire length of the stroke. Of
course, the shape of some work surfaces will not permit
this. However, the same spraying distance should be
kept whenever possible.
5. Do not move the spray gun by flexing your wrist. The
result of this is shown in Figure 8. Rather, move the
spray gun with a smooth stroke of the entire arm and
shoulder. Maintain the same arm speed all the way
through the stroke. The result of this is shown in Figure

the tip. If the tip becomes plugged while spraying, proceed
as follows:
1. Lock spray gun trigger OFF so that the spray gun can't
spray.
2. Turn sprayer ON/OFF switch OFF.
3. Reduce pressure by turning the pressure control knob
counterclockwise. Turn priming valve knob to to
bleed pressurized paint in paint hose and spray gun
back into paint container.
4. Remove tip guard assembly with spray tip and sealing
washer from spray gun as shown in Figure 3, page 10.
5. Remove spray tip and sealing washer from tip guard
assembly.
6. Soaktipguardassembly, spray tip, and sealing washer
in solvent. Then clean them with a stiff brush. A tooth-
pick, wood chip, or sharpened matchstick can be used
to clean the spray tip hole.

SPRAY GUN FILTER CLEANING AND
CHANGING
Clean or change the spray gun filter at least once per
painting day, some types of latex paint may require filter
cleaning or changing more often.
Thefilterisbestcleanedwithabrushdippedinappropriate
solvent. Never poke the filter with a sharp instrument.
If the filter is not cleaned or changed at the proper time, it
will plug from the top down. When there is about 1 inch or
so of the filter left that isn’t plugged, the heavy flow of paint
will blow pinholes in the filter. An example of this is shown
in Figure 12.
Never clean the spray tip hole with a wire or metal
object as these items will cause damage.
CAUTION
7. Reassemblethespraytip,sealingwasher,andtipguard
assembly onto the spray gun the same way you did
when you assembled the unit. See “ASSEMBLY OF
SPRAY GUN”, page 10.
To remove and replace the filter, proceed as follows:
1. Lock spray gun trigger OFF.
2. Turn sprayer ON-OFF switch OFF.
3. Reduce pressure by turning the pressure control knob
counterclockwise. Turn priming knob to . This will
drain the pressurized paint in the paint hose and spray
gun back into the paint container.
4. Remove the paint hose from the spray gun as shown in
Figure 13.
5. Remove the handle from the spray gun.
6. Remove the old filter. Use a new filter, or clean the old
filter.
7. Stick small end of new or cleaned filter into spray gun
housing.
8. Screw handle back on spray gun.
9. Connect paint hose to spray gun.
Extra spray gun filters should be kept on hand.

CHECKING OPERATION OF INLET VALVE
See Figure 14 for location of inlet valve. The inlet valve
shouldbecheckedifthesprayerdrawsup littleor nopaint.
It is a good practice to check inlet valve operation before
spraying.If the sprayer has been in storage,the inlet valve
may be sticky.
To check inlet valve operation, proceed as follows:
1. Turn priming knob to .
2. Turn ON-OFF switch ON.
3. Letinletvalvesuckagainstthepalmofyourhand.Iflittle
or no suction is felt repeatedly move the plunger in and
out to lift inlet valve stem, as shown in Figure 14. Put in
a few drops of light oil or cleaner.
SUCTION FILTER CLEANING
The suction filter is located on the end of the suction tube.
A clean suction filter gives full delivery capacity and a
constantlevelofsprayingpressure.Cleanthesuction filter
as needed with a brush dipped in solvent.
THE PLUNGER DEVICE MUST BE LOOSENED PRIOR
TO ANY SERVICE OF THE OUTLET VALVE.
CAUTION
CHECKING OPERATION OF OUTLET
VALVE

little or no paint, or draws up paint, but doesn’t build
pressure. It is a good practice to check outlet valve opera-
tionbeforespraying.Ifthesprayerhasbeeninstorage,the
outlet valve may be sticky.
To check outlet valve operation, proceed as follows:
1. Turn priming knob to .
2. Turn ON-OFF switch to ON.
3. If above symptoms occur during priming of pump sim-
ply:
• Reduce pressure to 0.
• Push the plunger in and out to lift the ball off the seat.

When the diaphragm or diaphragm parts have to be re-
placed, proceed as follows:
1. Remove the 4 paint pump screws with a 6 millimeter
alIenwrench.Asyouremovethe4screws,also remove
the 4 washers that may remain in the holes.
Figure 15. - Remove paint pump screws
2. Take the paint pump housing off the hydraulic pump
housing.
3. Remove the old diaphragm and the old insert ring.
Figure 16.-Diaphragm Parts and Their Relationship to
Other Parts of the Sprayer.
4. When a new diaphragm is installed, a new insert ring
(see Figure 16) should also be installed. Install the new
Insert.Besuretoputtheflatsurfaceoftheinsertringinto
the flat surface of the paint pump.
REPLACING DIAPHRAGM OR
DIAPHRAGM PARTS
The diaphragm is the only separation between the paint
pump and the hydraulic pump. It pumps paint, but it also
serves as a gasket between the hydraulic pump and paint
pump. If the diaphragm membrane ruptures, paint will
probably get into the hydraulic housing. If adequately
cleaned up soon enough, the parts (bearing, piston, etc.)
can be saved. If the hydraulic housing is not cleaned up
soon enough, you may have internal freeze-up.
5. Installthenew diaphragm. Putthemembranestemand
