GENERAL SAFETY RULES
WARNING! Read and understand
all instructions. Failure to follow all
instructions listed below may result in electric
shock, fire 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
a) Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
ammable liquid, gases, or dust. Power tools
create sparks which may ignite the dust or
fumes.
c) Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
a) 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.
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.
b) 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.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) 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.
e) 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.
3
Personal Safety
a) 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.
b) 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.
c) Avoid accidental starting. Ensure the
switch is in the off position before plugging
in. Carrying tools with your finger on the
switch or plugging in tools that have the
switch on invites accidents.
d) 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.
e) Do not overreach. Keep a proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
f) 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.
g) 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
a)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.
b)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.
c)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.
d)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.
e)Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
4
f)Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g)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.
SPECIFIC SAFETY RULES
WARNING: HIGH PRESSURE. Never leave
pressurized system unattended. Always
follow the Pressure Relief Procedure.
Take precautions to avoid high pressure
component rupture.
DANGER: INJECTION INJURY. Skin injection
by high pressure paint is not a simple cut. It
must be treated surgically immediately.
WARNING: FIRE AND EXPLOSION HAZARD.
Take all precautions to avoid sources of
sparks and ignition when spraying. Keep the
machine at least 8 meters away from the
spraying operation.
WEAR PROTECTIVE EQUIPMENT AT ALL TIMES.
Always use a respirator, eye protection and
protective clothing.
If the supply cord of this power tool is
damaged it must be replaced by a specially
prepared cord available through the service
organization.
Specic safety rules for Airless Sprayers
HANDLE THIS UNIT AS YOU WOULD A LOADED
WEAPON!
Extreme high pressure spray can cause
extremely serious injury.
OBSERVE ALL WARNINGS!
Keep clear of moving parts when starting
or operating the sprayer. Do not put
your fingers into any openings to avoid
amputation by moving parts or burns on
hot parts. When starting the motor, maintain
a safe distance from moving parts of the
equipment.
Before adjusting or servicing any mechanical
part of the sprayer, follow the PRESSURE
RELIEF PROCEDURE.
EXPLOSION RISK FROM HALOGENATED
HYDROCARBON SOLVENTS
Never use halogenated hydrocarbon
solvents in this machine.
5
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 fingers over
the spray tip. Do not use a rag or any
other materials over your fingers. 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.
• ALWAYS 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.
• ALWAYS wear a spray mask, gloves and
protective eye wear while spraying.
• ALWAYS ensure fire extinguishing
equipment is readily available and
properly maintained.
NEVER LEAVE SPRAYER UNATTENDED WITH
PRESSURE IN THE SYSTEM. FOLLOW PRESSURE
RELIEF PROCEDURES
6
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.
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 fluid under
pressure. If the tip or line is plugged,
follow the pressure relief procedure
and helps prevent accidentally placing
your fingers 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 off build up around the
spray tip.
TOXIC FLUID HAZARD
• ALWAYS remove tip guard & tip to
clean AFTER pump is turned off 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 uid
according to manufacturer, local, state
& national guidelines.
• ALWAYS wear protective eyewear,
gloves, clothing and respirator as
recommended by uid manufacturer.
TIP GUARD
• ALWAYS have the tip guard in place
on the spray gun while spraying. The tip
guard alerts you to the injection hazard
HOSES
• Tighten all of the fluid connections
securely before each use. High pressure
fluid can dislodge a loose coupling or
7
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, fire 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.
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.
8
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 sufficient 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 rmly 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.

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 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 at 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 qualified
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 fit the outlet, have the proper outlet
installed by a qualied 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 suffix 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

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.

SPRAYING -ALL MODELS
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 orice 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
14
bounce-back of the material and a rough
nish.
ALL MODELS
While spraying, consistently hold the gun
perpendicular, about 25-30cm (10-12
inches) away from the surface. Do not swing

rate of the spray gun movement, and
distance to surface.)
The numbers on the tip identify its orice size
and fan width. The first number on the tip
identies 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 orice size.
SPRAY TIP REPLACEMENT
SPRAY TIP SELECTION
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
orice size. Generally, use a smaller orice tip
For light viscosities (thin materials, like varnish),
and use a larger orifice tip for heavier
viscosities (thicker materials, like latex paints).
Spray tip orifice 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 flow rate or capacity
the sprayer can accommodate. Pump ow
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 orice tip size,
but different 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,
During use, especially with latex paint,
grit and impurities in the paint under high
pressure will cause the orice 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.

always strain paint before use with a paint
strainer bag and regularly clean all filters
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 ushing
solvent uid. 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 component
materials or epoxies, etc.
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 flushing fluid is beginning to
pump out. Now transfer the drain tube
to the waste bucket and continue to
flush until clear flushing fluid flows out.
For Hopper equipped models: Place the
drain tube in the original material bucket
and open the priming valve. Now run the
machine at low pressure to pump all of the
material out of the hopper and into the
original material bucket. Once the hopper
is empty, shut the machine off. Wipe the
hopper with a rag and ll it with a sucient
quantity of the appropriate ushing solvent
uid.
5. Shut off the machine and back off
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
17
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 flushing fluid 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 fluid
discharging from the gun. Allow the
fluid to discharge until all traces of
material are gone and pure flushing
uid is coming out.
13. Without releasing the trigger, transfer
the gun to the flushing bucket and
allow the ushing uid 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
ushing uid.
( If you are using a hopper,
continue flushing until the hopper is
empty.)
16. Clean the inlet strainer or hopper
strainer. Remove and clean it with a soft
brush in the appropriate solvent and
replace.
17. Clean the pump filter. Using the
supplied wrench, remove the pump
lter 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 filter 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 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.
18
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, fill 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.
(For hopper equipped models
pour a small quantity of storage solution
into the hopper.)
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
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.
• Clean the gun lter.
• Clean the tip.
• Clean the inlet strainer or hopper
strainer. As needed.
CAUTION: Never lay the pump on its back.
Material could ow 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: First loosen
the hand knob 90 to lower the fence 99.
(For brushless models loosen the butterfly
bolt 35 and to raise the fence 33 ).
reach the pin wrench end of the dual
purpose wrench through the opening

and tighten the packing nut. Replace
fence.
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.
To clean:
a. Using the supplied dual purpose
wrench, loosen the gland nut
to remove the suction tube (or
hopper).
b. Remove the check ball and ball
guide and clean all related parts.
c. Replace in the reverse of assembly
and tighten.
PUMP PACKINGS
pickup tube (3) from the bottom of the
pump. At the same time remove the
inlet ball seat disc (5), o-ring (6), check
ball (7) and ball guide (8)
2. Lay the machine on its back and
remove the heat sink electronics unit
(67). This will allow access to unplug the
pressure sensor (12) from the electronics
unit.
3. Disconnect the junction (42) and three
screws (40) on the pump filter bracket
and remove the pump lter.
4. Turn the pump until the piston is at its
lowest point. This will allow the retaining
ring (33) to be removed. This in turn will
allow you to push out the pump wrist
pin (35).
5. Remove the four bolts (9) to take off the
pump unit.
6. Replacement is the reverse of removal.
Grease the exposed portion of the
piston and wrist pin when assembling.
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 qualied repair technician.
To remove the pump and replace the
packings, follow the instructions below:
PUMP REMOVAL
1. Use the special spline wrench to loosen
the gland nut (2) and remove the
