the outlet and screw a conductive or
grounded 3000 psi spray hose onto
fluid outlet.
b. Connect an airless spray gun to the
other end of the hose, but do not
install the spray tip yet!
NOTE: Do not use thread sealer on
swivel unions as they are made to self
seal.
NOTE: The first 50' of hose should
always be 3/8".
2. Fill the Packing Nut/Wet Cup 1/3 full
with Throat Seal Oil (TSO) supplied.
See Figure 5.
3. Check the engine oil level.
a. Unscrew the oil fill plug. The
dipstick is attached to the plug.
b. Without threading the plug into
place, check to be sure the oil is up
to the top mark on the dipstick.
c. If oil is needed, refer to engine
manual.
4. Fill the fuel tank.
Fuel spilled on a hot
surface can cause a
fire or explosion and cause serious
bodily injury and property damage.
Always shut off engine and let it cool
before filling the tank, and carefully
follow steps a to c below, making sure
you do not spill any fuel.
a. Close the fuel shutoff valve.
b. Use only clean, fresh, wellknown brands of unleaded regular
grade gasoline.
c. Remove the fuel cap and fill
tank. Be sure the air vent in the fill
cap is not plugged so fuel can flow
to the carburetor, then replace the
cap.
SPRAY TIP SELECTION
See Tip Selection Chart on Page 6.
Spray tip selection is based on paint
viscosity, paint type, and job needs. For
light viscosity (thin paints), use a
smaller tip. For heavier viscosities
(thicker paints), use a larger tip size.
Spray tip 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 flow rate is
measured in gallons per minute (GPM).
PATTERN WIDTH
Thickness of the paint coat is
determined by spray tip “fan width,”
rate of the spray gun movement, and
distance to surface.
SPRAY TIP SELECTION
Two tips having the same tip size, but
different pattern widths, will deliver
the same amount of paint over a
different area (wider or narrower
strip).
A spray tip with a narrow pattern
width makes it easy to spray in tight
places.
SPRAY TIP REPLACEMENT
During use, especially with latex paint,
high pressure will cause the orifice to
grow larger. This destroys the pattern.
Replace tips before they become
excessively worn. Worn tips waste
paint, cause overspray, make cutting-in
difficult, and decrease sprayer
performance.

Operation
STARTING UP
1. Learn the functions of the controls
(see “How to Spray / Important
Components” for more
information).
2. Prepare the Material
a. Prepare the material according
to material manufacturer's
recommendations.
b. Place the pump or suction tube
into the material container.
3. Start the sprayer.
a. Prime/PR Valve must be open in
the priming position.
b. Pressure Control Knob must be
in low pressure position.
c. Follow procedure under “How
to Flush,” page 5, Steps 6 to 12.
To stop the unit in
an emergency or
before performing any service or
maintenance procedure follow the
Pressure Relief Procedure on page 3 to
relieve the fluid pressure.
4. Prime the pump.
a. Allow pump to operate until
paint comes from gun.
b. Release the trigger and engage
the gun safety latch.
c. Turn Prime Valve OPEN to the
prime position ensuring the
pressure is released from the
system.
d. Turn Pressure Control Knob to
minimum pressure.
e. Install spray tip onto gun.
f. Close the prime valve to the
pressure position.
g. Turn the pressure control knob
to desired spray pressure.
h. Disengage the gun safety lock
and you are ready to start
spraying.
If you spray paint
into the paint
bucket, always use the lowest spray
pressure and maintain firm metal-tometal contact between gun and
container.
5. Adjust pressure.
a. Turn the Pressure Control Knob
clockwise to increase pressure and
counterclockwise to decrease
pressure.
b. Always use the lowest pressure
necessary to completely atomize
the material.
Operating the
sprayer at higher
pressure than needed wastes material,
causes early tip wear and reduces the
life of the spray equipment.
c. If more coverage is needed, use
a larger tip rather than increasing
the pressure.
d. Check the spray tip. The tip size
and angle determine the pattern
width and flow rate.
6. Reduce clutch wear.
a. The first 50 feet of airless spray
hose should be 3/8", the larger
diameter works as a pulsation
damper and saves unnecessary
cycling of the clutch. A minimum
of 100 feet of hose should be used.
b. Adjust the Engine Speed and
Pump Pressure. First set the
throttle lever to the maximum
RPM setting (fully left). Trigger the
gun onto a test paper to check the
spray pattern and atomization.
Adjust the Pressure Control Knob
until you get a good pattern.
Reduce RPM of engine to support
pressure without overworking
engines.
7. Clean tip if clogged. If tip is
becoming worn, replace it. Worn
tips waste paint, cause overspray,
make cutting-in difficult, and
decrease sprayer performance.
IMPORTANT: Always follow the
Pressure Relief Procedure on page 3
before servicing unit.
Never hold your
hand, body, fingers,
or hand in a rag in front of the spray
tip when cleaning or checking it for a
cleared tip. Always point the gun
toward the front or into a waste
container when checking to see if the
tip is cleared or when using a selfcleaning tip.
a. Follow the Pressure Relief
Procedure on page 3.
b. Clean the front of the tip
frequently (with toothbrush only)
during the day to keep material
from building up and clogging the
tip.
c. To clean and clear a tip if it clogs,
refer to the separate instruction
manual received with your gun and
nozzle.
NOTE: When pausing during a paint
job, keep tip clean by locking the gun
and submerging the tip in a small
bucket of paint thinner. This will help
reduce buildup and drying of paint in
tip, tip guard, and gun.
Clean a clogged
standard flat tip
only after it has been removed from
the gun. Follow the Pressure Relief
Procedure on page 3.
8. When shutting off the sprayer,
follow this procedure.
a. Whenever you stop spraying,
even for a short break, follow the
Pressure Relief Procedure on page 3.
b. Clean the tip and gun as
recommended by your separate
gun instruction manual.
c. Flush the sprayer at the end of
each work day if the material you
are spraying is water-based, or if it
could harden in the sprayer
overnight. See "Flushing" on page 4.
Use a compatible solvent to flush,
then fill the pump and hoses with an
oil based sovent such as mineral
spirits.

SPRAY TECHNIQUE
Good Spray Gun Technique is at the
core of any spray paint operation.
Operator skill and efficiency is as
important as good equipment and
good paint. Good spray technique is a
skill that can be developed by
following these simple instructions.
If you are not familiar with spraying
techniques, study this section of your
manual and practice the proper
technique on pieces of cardboard or a
suitable surface.
Hold the spray gun 12 - 15 inches away
from the work surface and keep it
perpendicular (straight) to the surface.
Move the spray gun parallel to the
work and at a right angle to the
surface. (See Figure 6).
Move the gun at a steady rate in order
to apply a good coverage. The wet
coat should be just under the thickness
at which a run or sag will occur. Slow
gun movement or gun held too close
will result in an overly wet or thick wet
or thick coat coverage that is likely to
run or sag.
Do not wave the spray gun. This
waving is called arching. Instead, hold
the spray gun at a 12 to 15 inch
distance perpendicular from the work.
(See Figure 7.)
The closer the spray gun is held to the
work, the thicker the paint is deposited
and the faster the gun must be moved
to prevent sags and runs. Holding the
gun too far from the work will cause
excessive fog, overspray, and a thin
and grainy coat.
It is important to "trigger" the gun
after gun movement (arm movement)
has started and release trigger (shut
gun off) before gun movement ends.
Gun movement is always longer than
actual paint (spray) stroke. In that
manner, even blending and uniform
paint coat thickness is achieved over
the entire surface. When the gun is in
motion as the trigger is pulled, it
deposits an even amount of paint.
Overlap the previous pass by half the
width of the spray pattern. Aim at the
bottom of the previous pass.
Adjust Pressure Control Knob so that
paint is completely atomized from the
spray gun. Insufficient pressure will
result in “tailing.” Too much pressure
will result in excess fog and overspray,
excessive tip wear, and increased
sprayer wear and tear.
Always use the lowest pressure possible
to obtain desirable results. Test the
spray pattern on a piece of cardboard
or other surface.
To cover “inside” and “outside”
corners (on walls or other objects), aim
the spray gun toward the center of the

1. Turn "Pressure Calibration" Trimpot
adjustment on electrical control
board in the counter clockwise
direction at least 15 revolutions.
2. Connect 5000 psi glycerine pressure
guage on output of pump between
fluid pump and airless hose to
monitor Fluid Pump Pressure.
3. Start engine and run at maximum
RPM. Turn Prime/Pressure Relief
Valve to the open (Prime) position.
Turn Pressure Control Knob to
maximum position (fully clockwise).
4. Using an insulated screwdriver,
adjust "Pressure Calibration"
Trimpot by turning clockwise until
the clutch engages. When the
clutch engages the pump will
commence Priming. When pump is
primed, turn the Prime/Pressure
Relief Valve to the Closed (Pressure)
position. The pump will begin to
pressurize and the clutch will
disengage at a low pressure.
Continue turning the Trimpot
clockwise to increase pressure to
3000 psi.
5. Trigger gun. The pressure should
drop approximately 350-400 psi
(when using a 3/8" hose), the clutch
will engage and build pressure to
3000 psi and disengage. Trigger
gun several times to ensure proper
pressure setting.
6. Turn Pressure Control Knob to
minimum position. The clutch
should disengage and pump stop
moving.
7. Secure leads with tie strap.
8. Replace cover on unit. Ensure the

NOTE: After all the rod locknuts are
tight, the alignment of both rods
should allow easy assembly and
disassembly of the coupling. If there is
any binding, loosen and retighten all
the rod locknuts to improve the
alignment. Misalignment causes
premature wear of seal and packings.
7. Tighten the packing nut until there
is resistance, then tighten it 1 full
turn. Approximately 4 threads will
show when new packings are
installed. Fill the wet cup of the
packing nut 1/3 full with Throat

Maintenance
REGULAR MAINTENANCE
1. Always stop the pump at the
bottom of its stroke when you take
a break or at the end of the day.
This helps keep material from
drying on the rod and damaging
the packings.
2. Keep the displacement pump
packing nut/wet cup1/3 full of TSO
(Throat Seal Oil) at all times. The
TSO helps protect the packings and
rod.
3. Inspect the packing nut daily.
Your pump has a patented "Triple
Life Packing System". Packing life
will be extended a minimum of
3 times if the following Packing
Tightening Procedure is
followed:
AL2810
13
Airless Paint Systems
Operating Instructions and Parts Manual

Maintenance (Cont.)
Inspect the packing nut daily. If
seepage of paint into the packing
nut and/or movement of the piston
upward is found (while not
spraying), the packing nut should
be tightened enough to stop
leakage only, but not any tighter.
Overtightening will damage the
packings and reduce the packing
life.
4. Lubricate connecting rod pin every
3 months.
OIL AND LUBRICATION PROCEDURE
Figure 12 shows the necessary steps
involved in proper lubrication.

STEP 1: Ensure that the pressure control knob is in the maximum (fully clockwise) position.
STEP 2: Remove the upper and lower clutch and electrical covers.
STEP 3: Check all electrical connections between the engine magneto, sensor, control board and clutch for loose connections
or damaged leads. See Figure 8 on page 9.
STEP 4: Disconnect the two leads from the control board (blue) and the clutch assembly (black). Using a multimeter, with
the engine at maximum RPM, pressure control knob in the maximum position and the prime valve open (priming) position,
test the DC voltage across the boards leads (blue). This voltage must be 13-14 VDC. If the readings are correct, the board,
sensor and magneto are okay and the problem is the clutch assembly. If this is the case, proceed to Step 5. If the voltage is
outside this range go to Step 7.
STEP 5: Measure resistance between the clutch leads (black). This value must be 10-16 ohms. If this reading is out of
specifications the clutch is defective and must be replaced, otherwise continue troubleshooting.
STEP 6: If the clutch resistance readings of Step 5 are correct, check the spacing between the clutch field and plate. The gap
must be approximately .028". If this gap is too wide, remove the spacer from the clutch assembly. Should the clutch still not
engage, replace the clutch assembly. See page 11.
STEP 7: When the DC voltage from the board is not 13-14 VDC, disconnect the control board lead (black) from the engine
magneto lead (pink), located on the side of the engine. With the engine at maximum RPM, pressure control knob in
maximum (fully clockwise) position and prime valve open (priming), read the AC voltage from the magneto lead to the
sprayer frame. This reading should be 11-30 VAC. If outside this range, contact your local Honda repair facility for magneto
replacement. If the magneto is producing the proper AC voltage, continue to Step 8.
STEP 8: Test the sensor by reading the resistance between the red and black wires. The resistance runs between 1.8-3.5
kohms. A defective sensor usually shows no resistance (open). If the reading is outside standards, replace the sensor. An
alternative method to test the sensor, is to plug a new sensor into the board and see if the clutch will engage. Caution!
When using this method, ensure prime/pressure valve is in the prime position. This is important because the sensor plugged
into the board is not measuring pressure in the fluid section.
STEP 9: When Steps 7 and 8 have been completed and the magneto and sensor check good, the electrical control board is
the only item left, replace the board. See page 8.
