GENERAL SAFETY RULES
WARNING! Read and understand all
instructions. Failure to follow all instructions
listed below may result in electric shock, re
and / or serious personal injury. The term “power
tool” in all of the warnings listed below refers to
your mains-operated (corded) power tool.
SAVE THESE INSTRUCTIONS.
WORK AREA
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquid, gases, or dust. Power
tools create sparks which may ignite the dust
or fumes.
3. Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce the risk of
electric shock.
2. Grounded tools must be plugged into an
outlet properly installed and grounded in
accordance with all codes and ordinances.
Never remove the grounding prong or
modify the plug in any way. Do not use
any adaptor plugs. Check with a qualified
electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools
should electrically malfunction or break down,
grounding provides a low resistance path to
carry electricity away from the user.
3. Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
4. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
5. Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep the cord away from heat,
oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged or
entangled cords increase the risk of electric
shock.
6. When operating a power tool outdoors,
use an outdoor extension cord suitable
for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use tool while you are tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
2. Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
3. Avoid accidental starting. Ensure the switch
is in the off position before plugging in.
Carrying tools with your nger on the switch
or plugging in tools that have the switch on
invites accidents.
4. Remove adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the tool may
result in personal injury.
5. Do not overreach. Keep a proper footing
and balance at all times. This enables better
control of the power tool in unexpected

4
situations.
6. Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in
moving parts.
7. If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of these devices can reduce dust-
related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at
the rate for which it was designed.
2. Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.
3. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
4. Store idle tools out of reach of children and
do not allow persons unfamiliar with the
power tool or these instructions to operate
the power tool. Power tools are dangerous in
the hands of untrained users.
5. Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may aect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
7. Use the power tool, accessories and
tool bits etc., in accordance with these
instructions and in the manner intended
for the particular type of power tool, taking
into account the working conditions and
the work to be performed. Use of the power
tool for operations different from intended
could result in a hazardous situation.
SERVICE
Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
If the supply cord of this power tool is damaged
it must be replaced by a specially prepared cord
available through the service organization.

EXPLOSION RISK FROM HALOGENATED
HYDROCARBON SOLVENTS
Never use halogenated hydrocarbon solvents in this
machine.
Contact with aluminum parts may cause an
explosion.
Some of the most common of these solvents
are: Carbontetrachloride, Chlorobenzene,
Dichloroethane, Dichloroethyl Ether,
Ethylbromide, Ethylchloride, & Tethrachloethane.
PREVENT STATIC SPARKING FIRE/
EXPLOSIONS
Vapors created when spraying can be ignited by
sparks.
To reduce the risk of re, always locate the sprayer
at least 20 feet (6 m.) away from spray area. Do
not plug in or unplug any electrical cords in the
spray area. Doing so can cause sparks which can
ignite any vapors still in the air. Follow the coating
& solvent manufacturers safety warnings and
precautions.
MEDICAL ALERT - Airless Spray Injection
Injuries
If any uid appears to penetrate your skin,
GET EMERGENCY MEDICAL CARE AT
ONCE. DO NOT TREAT AS AN ORDINARY
CUT.
High pressure fluids from spray or leaks are
powerful enough to easily penetrate the skin and
cause extremely serious injection injury, leading to
the possible need for amputation.
• NEVER point the spray gun at anyone or any
part of the body.
• NEVER put your hand or ngers over the spray
tip. Do not use a rag or any other materials
over your ngers. Paint will penetrate through
these materials & into the hand.
• NEVER try to stop or deflect leaks with your
hand or body.
• ALWAYS have the tip guard in place when
spraying.
• A LWAYS lock the gun trigger when you stop
spraying.
• ALWAYS remove tip from the gun to clean it.
• NEVER try to "blow back" paint, this is not an
air powered sprayer.
• ALWAYS follow the PRESSURE RELIEF
PROCEDURE before cleaning or removing the
spray tip or servicing any system equipment.
• Be sure the equipment safety devices are
operating properly before each use.
• Tighten all of the fluid connections before
each use.
• NEVER alter equipment in any manner.
• NEVER smoke while in spraying area.
• NEVER spray highly ammable materials.
• NEVER use around children.
• NEVER allow another person to use sprayer
unless he is thoroughly instructed on its safe
use and given this operator’s manual to read.
• A LWAYS wear a spray mask, gloves and
protective eye wear while spraying.
• ALWAYS ensure re extinguishing equipment
is readily available and properly maintained.
NEVER LEAVE SPRAYER UNATTENDED WITH
PRESSURE IN THE SYSTEM. FOLLOW PRESSURE
RELIEF PROCEDURES
ALWAYS INSPECT SPRAYING AREA
• Keep the spraying area free from obstructions.
• Make sure the spraying area has good
ventilation to safely remove vapors and mists.
• NEVER keep flammable material in spraying
area.
• NEVER spray in vicinity of open ame or other
sources of ignition.
• The spraying area must be at least 20 ft. away
from spray unit.

7
SPRAY GUN SAFETY
• ALWAYS set gun safety lock in the "LOCKED"
position when not in use & before servicing or
cleaning.
• NEVER remove or modify any part of the gun.
• ALWAYS REMOVE THE SPRAY TIP when
cleaning. Flush unit at the LOWEST POSSIBLE
PRESSURE.
• ALWAYS check operation of all gun safety
devices before each use.
• Be very careful when removing the spray tip
or hose from the gun. A plugged line will
contain uid under pressure. If the tip or line is
plugged, follow the pressure relief procedure
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 ngers or any part of
your body close to the spray tip.
SPRAY TIP SAFETY
• Use extreme caution when cleaning or
changing spray tips. If the spray tip clogs
while spraying, engage the gun safety latch
immediately. ALWAYS follow the PRESSURE
RELIEF PROCEDURE and then remove the
spray tip to clean it.
• NEVER wipe o build up around the spray tip.
TOXIC FLUID HAZARD
• ALWAYS remove tip guard & tip to clean
AFTER pump is turned o and the pressure is
relieved by following the PRESSURE RELIEF
PROCEDURE.
• Hazardous fluid or toxic fumes can cause
serious injury or death if splashed in eyes or on
skin, inhaled or swallowed. Know the hazards
of the fluid you are using. Store & dispose of
hazardous fluid according to manufacturer,
local, state & national guidelines.
• ALWAYS wear protective eyewear, gloves,
clothing and respirator as recommended by
uid manufacturer.
HOSES
• Tighten all of the 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 and result in an injection injury or
serious bodily injury.
• Only use hoses with a spring guard. The spring
guard helps protect the hose from kinks or
other damage which could result in hose
rupture and cause an injection injury. Do not
allow kinking or crushing of hoses or allow it
to vibrate against rough, sharp or hot surfaces.
• Use only conductive fluid hoses for airless
applications. Be sure the gun is grounded
through the hose connections. Use only high
pressure airless hoses with static wire which
are approved for 3000 psi.
• NEVER use a damaged hose, which can
result in hose failure or rupture and cause an
injection injury or other serious bodily injury
or property damage. Before each use, check
entire hose for cuts, leaks, abrasions, bulging
of the cover, or damage or movement of
couplings. If any of these conditions exist,
replace the hose immediately.
• NEVER use tape or any device to try to mend
the hose as it cannot contain the high pressure
fluid. NEVER ATTEMPT TO RECOUPLE THE
HOSE. A high pressure hose is not possible to
recouple.
GROUNDING
• Ground the sprayer & other components in the
system to reduce the risk of static sparking, re
or explosion which can result in serious bodily
injury and property damage. For detailed
instructions on how to ground, check your
local electrical code.
• ALWAYS ensure switch is in OFF position
before plugging unit in.

8
Always Ground All of These Components:
1. 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.
Use only a 3 wire extension cord that has a
grounding plug, and a receptacle that will
accept the grounding plug on the product.
Make sure your extension cord is in good
condition. When using an extension cord, be
sure to use one heavy enough to carry the
current your product will draw. If in doubt, use
the next heavier gauge.
2. Fluid hose: use only grounded hoses.
3. Spray gun or dispensing valve: grounding
is obtained through connection to a properly
grounded uid hose and pump.
4. All solvent pails must be conductive metal
material and properly grounded. Do not
place on a non conductive insulating
surface unless a ground wire is added to a
true earth such as a metal water pipe.
ALWAYS ensure re extinguishing equipment
is readily available and properly maintained.
FLUSHING SAFETY
WHEN SPRAYING & CLEANING WITH FLAMMABLE
PAINTS AND THINNERS
1. When spraying with flammable liquids,
the unit must be located a minimum of 25
feet away from the spraying area in a well
ventilated area. Ventilation must be sucient
enough to prevent the accumulation of
vapors.
2. To eliminate electrostatic discharge, ground
the spray unit, paint bucket & spraying object.
See GROUNDING. Use only high pressure
airless hoses approved for 3000 psi which is
conductive.
3. Remove the spray tip before flushing. Hold
the metal part of the gun firmly to the side
of a metal pail & use the lowest possible uid
pressure during ushing.
4. Never use high pressure in the cleaning
process. USE MINIMUM PRESSURE.
5. Do not smoke in spraying/cleaning area.
NEVER use cleaning solvents with flash points
below 140 degrees F. Some of these are: acetone,
benzene, ether, gasoline, naptha. Consult your
supplier to be sure.
ASSEMBLY
Tools needed: Two adjustable wrenches-not
included.
1. Attach the hose to the pump and tighten
with a wrench.
2. Attach the hose to the gun and tighten with
two wrenches.
ELECTRICAL CONNECTION
The network voltage must conform to the
voltage indicated on the tool name plate. Under
no circumstances should the tool be used when
the power supply cable is damaged. A damaged
cable must be replaced immediately by an
authorized Customer Service Center. Do not try
to repair the damaged cable yourself. The use of
damaged power cables can lead to an electric
shock.
Grounding Instructions
This product must be grounded. In the event of an
electrical short circuit, grounding reduces the risk
of electric shock by providing an escape wire for
the electric current. This product is equipped with a
cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into
an outlet that is properly installed and grounded in

9
accordance with all local codes and ordinances.
WARNING - Improper installation of the
grounding plug can result in a risk of electric
shock.
If repair or replacement of the cord or plug is
necessary, do not connect the green grounding
wire to either flat blade terminal. The wire with
insulation having a green outer
surface with or without yellow stripes is the
grounding wire and must be connected to the
grounding pin. Check with a qualied electrician or
serviceman if the grounding instructions are not
completely understood, or if you are in doubt as
to whether the product is properly grounded. Do
not modify the plug provided. If the plug will not
t the outlet, have the proper outlet installed by a
qualied electrician.
IMPORTANT: use only a 3-wire extension cord
that has a 3-blade grounding plug and a 3-slot
receptacle that will accept the plug on the product.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. an undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
a 12 gauge cord is recommended. If an extension
cord is to be used outdoors, it must be marked with
the sux W-A after the cord type designation. For
example, a designation of SJTW-A would indicate
that the cord would be appropriate for outdoor use.
OPERATION
Before beginning always check and tighten all
ttings securely.
WARNING: A loose connection could burst loose
under pressure causing a hazardous condition.
Ensure that all connections are tight. This
includes both ends of the hose, the gun lter, the
tip guard, the pump lter, and the suction tube
gland nut
WARNING:Always ensure that the gun safety
latch is in the locked position.
The gun safety latch should always be set. The only
time the trigger should be unlocked is when the
gun is actually being triggered.
Leave the tip out of the gun when priming, ushing
and cleaning.
Lubricate the packings: Fill the packing nut/wet
cup with about 2-3 drops of throat seal oil.
Prepare at least three buckets
The rst bucket will hold the material to be sprayed.
The second bucket will hold flushing fluid, which
will be either mineral spirits (for oil-based materials),
lacquer thinner (for lacquers), water (for water based
materials), or soapy water (for converting from oil-
based or lacquer to water-based materials).
The third bucket will be the waste bucket.
FLUSHING
When to ush the pump
1. When the pump is filled with storage fluid,
as when you are operating your new airless
sprayer for the first time, or taking out of
storage. Flush with mineral spirits. (If you plan
to use water-based material see part 2 below.)
2. When changing between oil-based and water-
based materials. First ush with mineral spirits,
followed by a soapy water ush, followed by a
clear water ush.
3. When changing between water-based and oil-

based materials. First flush with clear water,
then ush with mineral spirits.
4. When changing colors. Flush with a
compatible solvent, such as water or mineral
spirits as needed.
5. When cleaning up. See the section on
CLEANUP later in this manual.
6. Storage. Leave the pump filled with a 50/50
mixture of mineral spirits and motor oil.
CAUTION: Never leave water in the pump for
more than about a day. Flush with mineral
spirits.
How to Flush
1. Place the suction tube/suction hose in a
ushing bucket lled with clean ushing uid:
either mineral spirits (for oil-based materials),
lacquer thinner (for lacquers), water (for
water-based materials), or soapy water (for
converting from oil-based to water-based
materials).
2. Separate the drain tube from the suction tube
(if they are clipped together) and place it in an
empty waste bucket.
3. Open the priming valve.
4. Ensure that the unit is turned off and the
pressure control knob is at the minimum
(anticlockwise ) setting. Plug the unit in.
5. Turn the unit on.
6. Turn the pressure control knob clockwise to
increase the pressure just enough to let the
pump run.
7. Allow the pump to run and watch the fluid
discharging from the drain tube. Allow the
fluid to discharge until completely clean
ushing uid is coming out. The hose and gun
also need to be ushed when changing colors
or when switching between dierent types of
materials/paints:
8. With the tip and tip guard removed from the
gun, point the gun into the waste bucket and
hold the trigger open.
WARNING: Risk of static sparking, fire
or explosion Hold the metal part of the
gun firmly to the side of a metal pail. All
solvent pails must be conductive metal

place on a non conductive insulating
surface unless a ground wire is added to a
true earth such as a metal water pipe.
9. Close the priming valve.
10. Allow the pump to run and watch the fluid
discharging from the gun. Allow the fluid to
discharge until completely clean ushing uid
is coming out.
WARNING: Do not release the gun trigger
during this process. If you release the
trigger, pressure will build in the line and
when you re-squeeze the trigger there will
be a splashback hazard.
11. Then turn the unit off and turn the pressure
control knob anticlockwise back to the
minimum setting. Then unplug the unit.
The pump is now clean and ready to be
primed with material.
PRIMING
This is a high pressure pump and all air and
unwanted uids must be bled out of the pump and
lines before spraying can begin.
Ensure that the tip and tip guard are removed from
the gun and the trigger is locked.
To prime
1. Place the suction tube in the material bucket.
2. Place the drain tube in a waste bucket and
open the priming valve.
3. Ensure that the pressure control knob is in the
minimum position and the unit is switched o.
Plug the unit in and turn it on.
4. Slowly turn the pressure control knob
clockwise to increase the pressure just enough
to let the pump run.
5. Allow the pump to run and watch the fluid
discharging from the drain tube. Allow the

11
uid to discharge until pure material is coming
out.
6. Point the gun into the waste bucket, unlock
the trigger and hold the trigger open. Then
close the priming valve.
7. Keep the trigger held open and allow the
pump to run and watch the uid discharging
from the gun. Allow the uid to discharge until
pure material is coming out. Turn the machine
o.
8. To further bleed out any air, point the gun
into the material bucket or hopper and hold
the trigger open. Turn the machine on and
allow clean material to recirculate. Watch the
material to make sure there are no air bubbles.
9. Now turn o the unit and lock the trigger
The drain tube may now be rejoined to the
suction tube in the material bucket.
The unit is now primed and ready to install the tip
and tip guard.
SPRAY TIP ASSEMBLY (reversible type tips)
WARNING: If the unit is pressurized, follow
the PRESSURE RELIEF PROCEDURE before
performing any adjustment with the tip.
Please see the section below “Spray Tip Selection”
to choose the right tip for your application.
1. Double check to be sure the gun safety latch is
locked before assembling tip and tip guard to
the gun.
2. If it is not installed, ensure the seal is snapped
in place on the seat and insert the seat into the
tip guard. Make sure that it is aligned to the
circular opening in the tip guard.
3. 3. Thread the tip guard onto the gun finger
tight only.
4. Insert the tip into the tip guard and ensure that
it is fully home. Rotate the tip all the way to the
forward position. (the arrow on the tip handle
will point forward). The tip can be rotated 180
degrees for clearing clogs.
5. Turn the tip guard assembly to the desired
orientation and tighten the lock nut rmly by
hand only.
WARNING: Never attempt to spray with the tip
in any position in-between either fully forward
or fully reversed. It could cause a high pressure
hazard.
You are now ready to spray.
PRESSURE RELIEF PROCEDURE.
Whenever you stop spraying, even for a short
break, follow the "Pressure Relief Procedure".
IMPORTANT! To avoid possible serious body
injury, always follow this procedure whenever
the sprayer is shut off, when checking it,
when installing, changing or cleaning tips,
when adding material and whenever you stop
spraying for any reason. Never leave the unit
unattended while in a pressurized condition.
1. Engage the gun safety latch. (See page 9)
2. Turn the unit o with the On/O switch .(See
page 2)
3. Disengage the gun safety latch and trigger
the gun to relieve residual fluid pressure.

4. Slowly turn the Priming Valve to the open
(priming) position to relieve any residual uid
pressure. Then close priming valve.
WARNING: If the SPRAY TIP OR HOSE IS CLOGGED,
Expect material splashing into the bucket while
opening the Priming Valve. So open the valve very
slowly and take precautions.
SPRAYING
Check the quality of the spray pattern on a piece of
scrap material, such as cardboard. Turn the Pressure
Control Knob Clockwise to increase pressure and
counterclockwise to decrease pressure.
Start with a low spray pressure and slowly increase
the pressure until a good spray pattern is achieved.
If the pressure is too low, the pattern will have“tails”,
which is a pattern with heavy, uneven edges. Keep
testing and increasing pressure until a smooth,
regular pattern is achieved. If the pressure is at
maximum and the pattern is still not ideal, either go
to a smaller orice tip or thin the material.
Do not raise the pressure any higher than is
necessary. Operating the sprayer at a higher than
necessary pressure wastes material, causes early tip
wear, and shortens sprayer life. Excessive pressure
can also result in bounce-back of the material and
a rough finish. (Running with the pressure at the
absolute maximum setting will also make the pump
run on and o in an irregular way.)
NOTE: Use proper pressure settings. Do not rely
on the readout to set the pressure. The only
way to set the pressure is to test spray on scrap
materials and observe the spray pattern.
While spraying, consistently hold the gun
perpendicular, about 25-30cm (10-12 inches) away
from the surface. Do not swing the gun. Do not tilt
the gun.
Trigger the gun before moving and release the
trigger after each stroke. Overlap each previous
stroke by half. Do this by aiming the tip to the edge
of the previous stroke.

Do not allow the material to run out. Remember
to follow the PRESSURE RELIEF PROCEDURE
before relling material. If the material does run
out, the pump will suck in air. This air must be bled
out before continuing. Follow the instructions for
“Priming” above.
TO REMOVE CLOGS FROM SPRAY TIP
(reversible tips)
1. Lock gun safety latch and follow the
PRESSURE RELIEF PROCEDURE.
2. Turn Tip handle 180 degrees.
3. Disengage trigger lock & trigger gun into
pail.
4. If the Tip handle appears locked loosen the
retaining nut. The handle will now turn easily.
5. Engage gun safety latch & return tip to the
spray position.
CLOGGED FLAT TIP
If you are using a at tip and the spray tip becomes
clogged, relieve pressure from hose by following
the "PRESSURE RELIEF PROCEDURE." Secure
gun with the safety latch, take o guard, take out
the tip, soak in appropriate solvent & clean with a
soft brush. (Do not use a needle or sharp pointed
instrument to clean the tip. The tungsten carbide
is brittle and can chip.)

position other than fully
forward or fully reversed.

The atomization pressure is the pressure at the gun, this will always be lower than the pressure at the
pump because the viscosity of the paint, the gun, as well as the length and diameter of the hose will all
cause a pressure drop.
There are many many variables which will effect the spraying pressure such as the temperature and
humidity, the hose, the paint, etc. So, after choosing the right sized tip, the operator must always ne-
tune the pressure to suit the unique conditions of his situation.

14
Note: To minimize tip wear, it is best to always
strain paint before use with a paint strainer bag
and regularly clean all lters and strainers.
Replace tips before they become excessively
worn. Worn tips waste paint, cause overspray,
make cutting-in difficult, and decrease sprayer
performance.
If the tip is the maximum rated size for your sprayer,
when it wears, it will exceed the ow rate capacity
of the machine. If when using the maximum
capacity tip size the pump cannot keep up, then
you know that the tip is worn beyond capacity.
CLEANUP
At the end of the day, the material in the line should
be recovered and the machine thoroughly cleaned.
This will avoid material drying in the pump or hose.
CAUTION: Under no circumstances allow material
to dry in the pump. If material dries in the pump
and hose, the pump will need to be completely
disassembled and rebuilt and the hose will need
to be discarded and replaced.
1. Relieve pressure in the system according to
the Pressure Relief Procedure.
2. Remove the tip and tip guard and soak in the
appropriate solvent for the material being
used.
3. Rinse off the suction tube and place in a
bucket of the appropriate flushing solvent
fluid. Usually this will be water (for water-
based materials), mineral spirits (for oil-based
materials) or lacquer thinner ( for lacquers).
Special flushing fluids may be required for
SPRAY TIP SELECTION (See chart 1)
Spray tip selection is based on paint viscosity, paint
type, and job needs. There are two variables to
identify the tip: orifice size and fan pattern width.
The main variable is tip orice size. Generally, use a
smaller orice tip For light viscosities (thin materials,
like varnish), and use a larger orice tip for heavier
viscosities (thicker materials, like latex paints).
Spray tip orice size is based on how many gallons
of paint per minute can be sprayed through the tip.
Do not use a tip larger than the maximum pump
ow rate or capacity the sprayer can accommodate.
Pump flow rate is measured in gallons per
minute (GPM) and liters per minute (LPM).
The other variable is the fan pattern width. Two tips
having the same orice tip size, but dierent fan
widths will deliver the same
amount of paint over a different area (wider or
narrower strip). A spray tip with a narrow fan width
makes it easy to spray in tight places. (Thickness of
the material coat per stroke is determined by spray
tip fan width, rate of the spray gun movement, and
distance to surface.)
The numbers on the tip identify its orice size and
fan width. The rst number on the tip identies the
fan width radius in inches. The last two numbers
identify the orifice size in thousandths of an inch.
So, for example, a 517 tip would have a 10 inch fan
width (5 inch radius) and a 0.017 inch orice size.
SPRAY TIP REPLACEMENT
During use, especially with latex paint, grit and
impurities in the paint under high pressure will
cause the orifice to grow larger from wear and for
the fan pattern width to degrade.
It is easy to determine the state of wear of the tip by
observing the fan pattern. As the tip wears, the fan
width will become narrower. A new tip will have a
pattern shaped like a narrow long rounded-corner
rectangle. As it wears it will turn into an oval shape.
When it is completely worn out it sprays a circle.
When the fan width decreases to about 2/3 of its
original size, it is considered worn out.

4. To reclaim the material in the pump, place
the drain tube in the original material bucket.
With the priming valve still in the
open position, turn the machine on and turn
the pressure control knob clockwise just
enough to run the pump. watch the material
discharging from the drain tube until the
material begins to thin. This indicates that the
ushing uid is beginning to pump out. Now
transfer the drain tube to the waste bucket
and continue to ush until clear ushing uid
ows out.
5. Shut o the machine and back o the pressure
control knob to minimum. Close the priming
valve.
6. To reclaim the material in the line, with the tip
and guard removed, point the gun into the
material bucket and hold the trigger open.
7. Place the waste bucket right next to the
material bucket.
8. Ensure that the pressure knob is in the
minimum position and turn the unit on.
9. With the trigger held open, slowly turn the
pressure knob clockwise to increase the
pressure just enough to let the pump run.
10. Allow the pump to run and watch the material
discharging from the gun. Allow the material
to discharge until the material begins to thin.
This indicates that the ushing uid is coming
up the hose..
11. Without releasing the trigger, quickly transfer
the gun from the material bucket to the waste
bucket next to it.
WARNING: Do not release the gun trigger during
this process. If you release the trigger, pressure
will build in the line and when you re-squeeze
the trigger there will be a splashback hazard.
12. Keep the trigger held open and allow the
pump to run and watch the uid discharging
from the gun. Allow the fluid to discharge
until all traces of material are gone and pure
ushing uid is coming out.
13. Without releasing the trigger, transfer the gun
to the ushing bucket and allow the ushing
fluid to recirculate for 2-3 minutes to make
sure that all traces of the material are cleaned
out.
14. Turn off the machine and unplug. Open the
priming valve to relieve residual pressure.
15. Remove the suction tube out of the flushing
uid.
16. Clean the inlet strainer or hopper strainer.
Remove and clean it with a soft brush in the
appropriate solvent and replace.
17. If your unit is equipped with the optional
pump filter, use a wrench (not supplied) to
remove the lter nut. Then remove the pump
filter and clean it with a soft brush in the
appropriate solvent. Then replace and tighten.
18. Clean the gun, tip, and gun filter. unclip the
hand guard and rotate it out of the way. Then,
using a wrench (not supplied) loosen the nut
on the bottom of the handle and remove the
handle to remove the gun lter. Clean the tip
and lter with a soft brush in the appropriate
solvent. Apply a small amount of light oil
such as WD-40 to the inside of the spray gun

HOURLY MAINTENANCE
We recommend after every hour of spraying, stop,
follow the Pressure Relief Procedure and perform
the following:
• Add about 2 drops of throat Seal Oil to
lubricate the packings.
• Clean the pump lter. (if so equipped)
• Clean the gun lter.
• Clean the tip.
• Clean the inlet strainer. As needed.
CAUTION: Never lay the pump on its back.
Material could flow backward and damage the
electronics or motor.
DAILY MAINTENANCE
1. Keep the displacement pump packing nut
lubricated with throat seal oil at all times.
Add about five drops of oil to the top of the
pump at the beginning of each day. Then two
drops for every hour of spraying. The throat
seal oil helps protect the piston, rod and
packings.
2. Inspect the packing nut daily. If either of the
following conditions exists the packing nut
should be tightened:
a. Seepage of material past the packing
is found.
b. While the system is pressurized
during the intervals when the motor
is not running, the piston doesn't
hold its position. Rather, it tends to
slip upward.
To tighten the packing nut: Reach the tommy bar
through the opening and tighten the packing nut.
CAUTION: The packing nut should be
tightened just enough to stop leakage only, but
not any tighter. Overtightening will damage the
packings and reduce packing life.
3. Clean the intake check ball and seat.
housing. Place the filter in the spray gun and
reassemble the unit by tightening the nut with
the wrench.
19. Clean the exterior of the sprayer with a rag
soaked in the appropriate solvent.
20. If flushing was with water, flush again with
mineral spirits to prevent corrosion inside the
pump.
CAUTION: Never leave water in the pump for any
length of time. Water will corrode the pump.
LONG TERM STORAGE
For long- term storage, ll the pump with a storage
solution made of a 50/50 mix of motor oil and
mineral spirits.
To ll the pump:
1. Place the both the suction tube and drain tube
in a small quantity of storage solution.
2. With the priming valve in the open position,
turn the machine on and turn the pressure
control knob just enough for the pump to run.
3. Watch the drain tube and as soon as the storage
solution appears in the tube, shut the machine
off and close the priming valve. This will trap
the storage solution inside the pump to protect
it.
MAINTENANCE
Every 50 hours of operation blow compressed air
through the motor while running at no load to clean
out accumulated dust. (If operating in especially
dusty conditions, perform this operation more often.)

17
To clean:
1. Remove the suction tube (73) by releasing the
hose clip (71) and pulling the hose free. Use a
wrench to loosen the gland nut.
2. Remove the check ball and ball guide and
clean all related parts.
3. Replace in the reverse of assembly and
tighten.
PUMP PACKINGS
The packings are a wearing part. If the pump can
no longer maintain pressure, has diffculty priming
and paint seeps into the throat of the pump, and
tightening the packing nut no longer helps, then
the packings will require replacement. This is best
entrusted to a qualied repair technician.
To remove the pump and replace the packings,
follow the instructions below:
PUMP REMOVAL
1. Remove the suction tube by releasing the
hose clip and pulling the hose free.
2. Turn the pump until the piston is at its lowest
point. To do this, it is necessary to remove the
left side frame leg (77) and then remove the 12
screws to remove the left side motor housing
(38). Then the motor may be turned by turning
the fan from the rear.
3. Loosen and remove the 4 socket cap screws
(65)
4. Pull the pump forward to disengage the
displacement piston (53) from the slot in the
bottom of the drive piston (45). (It must be at
its lowest point in order to disengage-see step
2 above)
5. The pump unit may now be lifted away.
6. Replacement is the reverse of removal. Grease
the junction slot of the drive piston when
assembling.
PACKINGS REPLACEMENT
1. Loosen the packing nut with the tommy bar
supplied and remove.
2. Pull out the piston.
3. Remove all parts and clean. Clamp the
displacement piston (53) in the soft jaws of a
vise and remove the ball seat fastener (56) to
allow removal of the small ball seat (54) and
the small check ball.
4. Discard all old packings.
5. Soak the new leather packings in W30 oil for at
least one hour before assembling.
6. Replace the packings, glands, o-rings and
check balls with the new parts from the
rebuild kit. Strictly follow the exact order and
orientation.
7. Replace piston and thread on the packing nut.
After resistance from the disc springs is felt,
tighten the packing nut a further 3/4 turn.

MOTOR MAINTENANCE
Every 50 hours of operation blow compressed air
through the motor while running at no load to clean
out accumulated dust. (If operating in especially
dusty conditions, perform this operation more
often.)
LUBRICATION – The gear case grease may be
changed every 200 hours of operation. This is best
entrusted to a qualied repair technician.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
When the brushes are worn to a length of 1/4", they
should be replaced as a set.
TO CHANGE THE BRUSHES
1. Unplug the machine.
2. Remove the brush cap with a slothead
screwdriver
3. Remove the brush.
4. Install new brushes in reverse order and
replace covers
If the replacement of the power supply
cord is necessary, this has to be done by the
manufacturer or their agent in order to avoid a
safety hazard.
WARNING: All repairs must be entrusted to an
authorized service center. Incorrectly performed
repairs could lead to injury or death.
