INTRODUCTION
The SL1500 sprayer is the choice of the high volume
contractors that need a machine that can pump extremely
heavy materials like wallboard mud and waterproofing
coatings. Their most popular application is spraying a skim
coat of wallboard mud to give a Level 5 finish using the
supplied size 627 REV-TIP.
Utilizing the proven SL pump platform in conjuction
with an oversized bottom mounted foot valve, it delivers
unprecedented suction. It is redefining the level of
productivity possible on demanding jobs that simply cannot
be handled by convential airless equipment.

GROUNDING
HOSES
Tighten all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling and result in
an injection injury or serious bodily injury.
Use only hose that has 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.
NEVER use a damaged hose, which can result in hose
failure or rupture and cause in injection injury or other
serious bodily injury or bodily damage. Before each use,
check entire hose for cuts, leaks, abrasion or bulging of
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. High pressure hose is not
recoupleable.
Help prevent damage to the hose by handling and routing
it carefully. Do not move the sprayer by pulling it with the
hose.
Ground the sprayer and 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.
ALWAYS GROUND ALL OF THESE COMPONENTS:
1. Sprayer: Connect a ground wire and clamp (supplied) to
a true earth ground.
2. Fluid Hose: use only grounded hoses.
3. Spray gun or dispensing valve: grounding is obtained
through connection to a properly grounded fluid hose
and pump.
4. Object being sprayed: according to your local code.
5. All solvent pails used when flushing should only be
metal pails which are conductive.
Once each week, check electrical resistance of hose (when
using multiple hose assemblies, check overall resistance of
unpressurized hose must not exceed 29 megohms (max)
for any coupled length or combination of hose lengths. If
hose exceeds these limits, replace it immediately.
Never exceed 500 Ft. (150 m.) overall combined hose
length to assure electrical continuity.
LABELING
ALWAYS INSPECT SPRAYING AREA
Keep all labels on the unit clean and readable.

4. ADJUSTING THE 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.
NOTE: OPERATING THE SPRAYER AT HIGHER
PRESSURE THAN NEEDED, WASTES MATERIAL,
CAUSES EARLY TIP WEAR, AND SHORTENS
SPRAYER LIFE.
c. If more coverage is needed, use a larger tip rather than
increasing the pressure.
WARNING
To stop the unit in an emergency, turn the engine off. Then
relieve the fluid pressure in the pump and hose as instructed
in the PRESSURE RELIEF PROCEDURE.
5. WHEN SHUTTING OFF THE SPRAYER
a. Whenever you stop spraying, even for a short break,
follow the PRESSURE RELIEF PROCEDURE.
b. Clean the tip & gun as recommended in the seperate
Gun Manual supplied with the gun.
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". Use a
compatible solvent to flush, then fill the pump and hoses
with an oil based solvent such as mineral spirits.
d. For long term shutdown or storage, refer to the
"Flushing" section of this manual.
WARNING
Be sure to relieve pressure in the pump after filling with
Airlessco Pump Conditioner.
AVOIDING TIP CLOGS
There is an easy way to keep the outside of the tip clean from
material build up:
Every time you stop spraying, for even a minute, lock the gun
and submerge it into a small bucket of thinner suitable for the
material sprayed.
Thinner will dissolve the buildup of paint on the outside of tip,
tip guard and gun much more effectively if the paint doesn't
have time to dry out completely.
d. Check the spray pattern. The tip size and angle
determines the pattern width and flow rate.
WARNING
FOLLOW THE "PRESSURE RELIEF PROCEDURE".
To reduce the risk of injection, never hold your hand, body,
fingers or hand in a rag in front of the spray tip when cleaning
or checking for a cleared tip. Always point the gun toward the
ground or into a waste container when checking to see if the
tip is cleared or when using a self-cleaning tip.
WARNING
When you spray into the paint bucket, always use the
lowest spray pressure and maintain firm metal to metal contact
between gun and container.

CLEANING SPRAY GUN
Immediately after the work is finished, flush the gun out
with a solvent. Brush pins with solvent and oil them lightly
so they will not collect dried paint.
Should the spray tip become clogged, relieve pressure
from hose by following the PRESSURE RELIEF
PROCEDURE. Secure gun with the safety latch, take
off guard, take out the tip, soak in appropriate solvent &
clean with a brush. (Do not use a needle or sharp pointed
instrument to clean the tip. The tungsten carbide is brittle
and can chip.)

TIP SELECTION GUIDE
Spray tip selection is based on paint viscosity, paint type, &
job needs. For light viscosities (thin paints), use a smaller
tip; heavier (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 maximum pump flow rate or capacity the sprayer can
accommodate. Pump flow rate is measured in gallons per
minute (GPM).
TIP IDENTIFICATION:
1ST 3-DIGITS identifies it as a REV-TIPTM for airless
paint spraying (P.N. 560-xxx) or a REV-TIP TM for airless
line striping (P.N. 562-xxxST).
4TH DIGIT is the fan width - the number is half the fan
width, e.g., 5 means a 10” fan.
5TH AND 6TH digits are for the orifice size and is
measured in thousandths of an inch, e.g., 17 = 0.017 inch
- The higher the number, the larger the tip.

*Pump will support tip worn to next larger size.
Thickness of the paint coat per stroke is determined by
spray tip "fan width", rate of the spray gun movement, and
distance to surface. 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.
12
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 decreases sprayer performance.
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, damaging
the packings.
2. Keep the displacement pump packing nut/wet cup 1/3 full of Airlessco Throat Seal Oil at all times. The TSO helps
protect the packings and rod.
3. Lubricate Connecting Rod Pin every 3 months.
4. Inspect the packing nut daily. Your paint pump has Airlessco's patented "Triple Life Packing System". Packing life will
be extended a minimum of 3 times if the proper packing tightening procedure is followed!
PACKING TIGHTENING PROCEDURE:
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 to the life of other piston pumps.

ELECTRIC MOTOR MAINTENANCE
1. LUBRICATION - This motor is supplied with prelubricated ball bearings, lubricated for the life of the
bearing.
2. MOTOR BRUSHES - need periodic inspection and
replacement as wear indicates. Brush wear is greatly
influenced by individual application. It is recommended
that brush wear be checked at early intervals of
operation in order to determine future required
inspection. Standard Leeson brushes have an initial
length of 1 and 1/4". When the brushes are worn to a
length of 5/8" they should be replaced.
TO CHANGE THE BRUSHES:
1. Unplug the machine.
2. Remove the cover over the motor.
3. Open the two covers at the rear of the motor.
4. Loosen the screw under the brush.
5. Pull out the wire.
6. Push the brush retainer clip in and withdraw.
7. Remove the worn brushes.
8. Install new brushes in the reverse order.
For long life, new brushes (Part # 301-146 for 110 volt, Part # 301-147 for 220 - 240 volts) need to have a run in period.
After changing brushes, set the machine for spraying. With a bucket of Pump Conditioner and water, a 50' 1/4" airless
hose, airless gun and tip on unit, open the prime valve and switch on. The pump will now prime. With pump running in the
prime mode, turn the pressure control knob to high pressure. (The pump has to cycle fast with no pressure in the pump).
Run the pump for 20 minutes and the brushes will be run in.

REPLACEMENT OF BELT/BELT ADJUSTMENT
NOTE: The Cog Belt System does not require alignment.
When upper sheave is placed on motor shaft it is pushed
on until a positive stop is reached. The set screws (Fig.
30, Item 50) are then loctited. The lower pulley is placed
on gearbox and held in place with keyway and snap ring
(Fig. 30, Item 23) The flange on upper sheave holds the
belt in alignment and the belt self aligns on lower pulley
eliminating having to align.
FIG. 13
REPLACEMENT OF BELT
1. Remove cover (Fig. 30, Item 42) from unit.
2. Remove Tensioner Assembly (Fig 30). Then loosen screws (Fig. 30, Item 53). Move gearbox forward to allow removal
and replacement of belt.
3. Retighten screws into gearbox until they bottom out. (Fig. 30, Item 53) This will align gearbox correctly.
4. Replace tensioner with bolts and leave loose to allow adjusting belt tension.
5. Tighten belt as shown in Figure 13. When properly tightened the deflection play should be 1/4 inch when pushing hard
with thumb. (20 ft/lbs)
NOTE: WHEN PLACING BELT ON PULLEYS AND INSERTING THE TENSIONER AGAINST BELT, ENSURE COGS
ON BELT ARE ENGAGED INTO COGS ON PULLEYS BEFORE TIGHTENING BELTS. ROTATING UPPER PULLEY
WHILE HOLDING THE TENSIONER AGAINST THE BELT WILL ALLOW PROPER ENGAGEMENT OF COGS PRIOR
TO TIGHTENING.

SERVICING THE FLUID PUMP
NOTE: CHECK EVERYTHING IN THE TROUBLESHOOTING CHART BEFORE DISASSEMBLING THE SPRAYER.
FLUID PUMP DISCONNECT
1. Flush out the material you are
spraying, if possible.
2. Follow the Pressure Relief
Procedure on page 8. Stop the
pump in the middle of down
stroke.
3. Remove the suction tube and
fluid hose (if so equipped) from
the fluid pump.
4. Remove the connecting rod
shield from the pump.
5. Remove 2 retaining rings and slip
the sleeve of the coupling down
and remove both coupling halves.
This will disconnect fluid pump
from the connecting rod.
6. Using a 7/8” box wrench,
disconnect the high pressure fluid
line from the pump.
7. Using a 9/16” wrench, unscrew
the two tie rod locknuts.
8. Pull the pump off the tie rods.
FIG. 14

1. Loosen the packing nut & extend piston rod to fully up position.
Slip sleeve over the piston rod. See fig. 15.
2. Insert one of the retaining rings through the packing nut and
rest the sleeve on top of it. See fig. 16 & 17.
3. Connect the connecting rod with the fluid pump by installing
the coupling halves. Slide sleeve over the coupling halves and
secure with retaining ring. See figure 18.
4. Remove the retaining ring from the packing nut and insert into
coupling halves. See figure 19
5. Secure the fluid pump housing to the tie rods and screw
locknuts with washers on loosely.
6. Tighten the tie rod locknuts evenly to 30 ft. lb NOTE: AFTER
ALL THE ROD LOCKNUTS ARE TIGHT, THE ALIGNMENT
OF BOTH RODS SHOULD ALLOW EASY ASSEMBLY AND
DISASSEMBLY OF THE COUPLING. IF ANY BINDING,
LOOSEN AND RETIGHTEN ALL THE ROD LOCKNUTS TO
IMPROVE THE ALIGNMENT. MISALIGNMENT CAUSES
PREMATURE WEAR OF SEAL AND PACKINGS.
7. Tighten packing nut clockwise until resistance against the
packings can be felt. Turn it one full turn more.
8. Start the pump and operate it slowly (at low engine speed)
to check the piston rod for binding. Adjust tie rod lock nuts if
necessary to eliminate binding.
9. Prime the unit and run at maximum pressure for several
minutes, then release the pressure & repeat step 6.
10.Fill the wet cup (packing nut) with five drops of TSO (Throat
Seal Oil).

TROUBLESHOOTING - MACHINE DOES NOT START
Cause
24
Steps
Control Settings
STEP 1: After making sure that the machine is plugged into the wall, verify that
the on-off switch is in the ON position and that the pressure control knob is
turned all the way to the right (clockwise for maximum pressure).
35A Circuit Breaker
STEP 2: Using your multi-meter, test the breaker for continuity or replace with a
new breaker. If the breaker reads good, move on to step three.
Power Source
STEP 3: Using a Phillips Head screwdriver, remove the eight screws holding the
pressure control assembly. Locate the light on the board indicating that there is
power (it will be red or green). If the light is OFF proceed to step four. If the light
is ON go to step six.
Power Source
STEP 4: Locate the L1 and L2 terminals on the board, and then using your
multi-meter check to make sure you have 110 volts AC across the two terminals
(the cord wires will still be attached). If there is no voltage at these leads, there
is no power getting to the machine. Check your power source (outlet, circuit
breaker, extension cord, and power cord). If you have AC voltage at the L1 and
L2 terminals, go to step 5.
Thermal Overload
STEP 5: Disconnect the two red motor leads (S1 & S2) and test for continuity
between them. No continuity means that the thermal coupler has opened due
to excessive motor heat. If the motor is still hot to the touch, allow it to cool and
then retest. If the motor is cool and there is not continuity on the red leads,
contact your local Airlessco Technical Support to repair/replace the thermal
coupler. Continuity shows that the motor's thermal coupler has not tripped.
Proceed to step six.
Pressure Control Assembly (Board)
STEP 6: If everything checks out in steps one through five and the power
indicating light is still out, replace the pressure control assembly.
Motor
STEP 7: Remove the motor brush covers and turn the machine on. Set the
potentiometer (POT) at maximum pressure and check for DC voltage across
both brush terminals. You should read greater than 80 volts DC. IF YOU DO
NOT HAVE DC VOLTAGE GO TO STEP EIGHT. If you have DC voltage,
turn the machine off and unplug it from the wall. Check to make sure that the
brushes are making good contact with the armature. Replace the brushes if
they are less than 5/8" long. If the brushes are good, replace the motor.
Sensor
STEP 8: Plug another sensor into the board and perform the zero calibration
procedure. If the machine starts to run, the sensor was bad. If there is no
replacement sensor available, use a multi-meter to test the resistance across
the red and black wires of the sensor (be sure to test at the plug). You should
read 1.5 - 3.5k ohms. A faulty sensor usually reads no continuity (open). If the
sensor passes all the tests move to step nine.
Pressure Control Knob
(Potentiometer)
STEP 9: Plug another potentiometer (POT) into the control board. If the
machine starts, the old POT is bad. When a replacement POT is not available,
remove the POT lead (with the machine turned off) from the control board and
test the resistance between the red and black wires (be sure to test at the plug).
The resistance should read between 8-12k ohms if it is outside of this range
replace the POT.
Pressure Control Assembly (Board)
STEP 10: If you have DC voltage at the motor brushes and all of the
components check out fine in steps eight and nine, replace the pressure control
assembly.
PRESSURE CONTOL ASS'Y CALIBRATION
NOTE: ANYTIME A SENSOR OR PRESSURE CONTROL ASSEMBLY (BOARD) OR BOTH ARE REPLACED, THE
FOLLOWING CALIBRATIONS MUST BE PERFORMED.
NOTE: PRESSURE CONTROL ASSEMBLIES (BOARDS) ARE NOW BEING EQUIPPED WITH A GREEN
GROUNDING WIRE ATTACHED. CONTECT THE GROUNDING WIRE TO TERMINAL BOX USING THE SAME
SCREW THAT HOLDS THE GROUNDING WIRE FROM THE POWER CORD.
1. ZERO CALIBRATION
1. Place prime/pressure relief valve in the prime (open)
position.
2. Set the pressure control knob to the minimum setting
(CCW).
3. Remove the screws and lower the pressure control
assembly.
4. Remove any jumper on the "P-ZR" terminal. Note: This
Jumper is no longer used.
5. Turn machine "ON" and ensure it is not cycling.
6. If the yellow light on the electrical board is ON and you
have "0000 " on the LCD display, the Zero Calibration
is complete no further adjustment is necessary. If the
light is ON and there are numbers on the display, use
an insulated screwdriver to turn the "ZERO" trimpot
counter-clockwise until the light goes out. Then turn
it clockwise until the yellow light comes on, continue
to turn the trimpot and the numbers will reduce untill
the LCD shows "0000." The Zero Calibration is now
complete. If you adjust beyond "0000 " the numbers will
start to increse.
If the digital display shows "- - -" and no yellow light, you
should turn the Zero trimpot clockwise until the
yellow light is on, continue turning until "0000 " is shown.
The goal is to see "0000 " on the digital display, this is
when you have Zero Calibration. Relying on the
yellow light is no longer used.
2. PRESSURE CALIBRATION
1. Complete the ZERO calibration, as per "ZERO
CALIBRATION" prior to commencing this calibration.
2. Attach a 50', 1/4" airless hose, airless gun with 0.017 tip
and a 5000 psi glycerin filled pressure gauge to pump.
3. Place the suction tube into a bucket of Coro-chek and
water.
4. Turn prime/pressure relief valve to the prime (open)
position.
5. Turn pressure control knob clockwise until machine
starts to prime.
6. Place the prime/pressure relief valve in the pressure
(closed) position.
7. While watching pressure gauge, slowly adjust the
pressure trimpot (clockwise to increase and counter
clockwise to decrease) until the maximum static
pressure is 3000 psi, with the pressure control knob
fully clockwise. Trigger the gun several times to ensure
pressure returns to 3000 psi .
3. LCD DISPLAY CALIBRATION
1. Complete the "ZERO CALIBRATION" and "PRESSURE
CALIBRATION" procedures prior to commencing this
calibration.
2. Turn pressure control knob up until system pressure is
above 2500 psi (as indicated on glycerin filled pressure
gauge) and the machine is not cycling.
3. Use an insulated screwdriver to adjust the Set trimpot.
Turn trimpot CCW until it clicks, then adjust to match
pressure against pressure gauge reading.
4. Move the pressure control knob to different settings and
trigger the gun several times to ensure that the
LCD continues to match the pressure gauge reading.
4. PASE LIMIT CALIBRATION
FORMERLY KNOWN AS THE LOW VOLTAGE OR
MASTER VOLTAGE CALIBRATION
1. Attach a 50', 1/4" airless hose, airless gun with .017
tip and a 5000 psi glycerin filled pressure gauge to the
pump.
2. Place the suction tube into a bucket of anti-freeze and
water.
3. Turn pump on and turn up pressure control until the
machine starts to prime.
4. Place the prime/pressure relief valve in the pressure
(closed) position.
5. Pressurize pump to 600 psi.
6. Trigger the gun several times noting the deadband (the
amount of pressure drop before the pump rebuilds to set
pressure).
7. If deadband is greater than 150 psi, adjust the phase limit
trimpot so that the deadband is less than 150 psi and the
pressure increase after the gun trigger is released is less
than 250 psi. These pressures are guidelines and may
vary slightly from pump to pump.
8. Reattach pressure control assembly to unit.
