INTRODUCTION
WHAT’S THE DIFFERENCE BETWEEN AIRLESS AND
CONVENTIONAL SPRAYERS POWERED BY AN AIR
COMPRESSOR?
We appreciate your decision to purchase a Lemmer
airless sprayer and believe you will find it a practical tool
for doing-it-yourself with professional looking results.
Compressor type sprayers mix paint with air to create a
fine spray pattern. The fine mist (which also creates
more overspray) produces the fine finish required for
automotive type work.
Your sprayer is capable of spraying a wide variety of
latex, oil-based and alkyd paints, as well as stains,
preservatives and other non-abrasive finishes. The
material you are spraying will have a direct effect on the
amount of pressure required for the optimum pattern and
coverage to be obtained. We recommend that before
actually beginning your job, you carefully read this
manual and practice with the sprayer until you feel comfortable using it.
Airless sprayers, on the other hand, pressurize material
only; they do not mix the material with air. By generating
pressures of up to 2500psi (pounds per square inch) and
spraying volumes of 1 gallon every three minutes the unit
is ideal for completing large jobs quickly. This high pressure also gives you a tight pattern with less overspray
than conventional sprayers. This results in better coverage and the need for only one coat in most cases.
The Lemmer L-1500 sprayers are also powerful and
versatile enough to be used with a variety of options
(extra lengths of hose, extensions, pressure feed rollers,
etc.) to make it an even more efficient tool. Ask your
retailer about the recommended accessories for your
particular task.

GENERAL DESCRIPTION
SPRAY GUN:
The spray gun is designed specifically for airless spraying. Since there is no compressed air to atomize the
paint, atomization is accomplished by forcing the paint at
a very high pressure (2500p.s.i) through a very small hole
(.015" diameter). Because of this high pressure, the spray
tip and gun valve are made of tungsten carbide for
maximum wear resistance. The gun body is made of a
tough copolymer plastic for lightweight and chemical
resistance.
PAINT PUMP:
The paint pump is simply a valve block with inlet, outlet,
prime, and outlet push-button valves. These valves
regulate the flow of the paint through the pump during
priming and spraying. The inlet, outlet and prime valves
are made of tungsten carbide and assembled into one
piece cartridge assemblies for easy service and replacement. The inlet and outlet valves work on opposing
strokes of the diaphragm to draw in and force out the
paint.
As a safety feature, the spray gun can be locked with the
trigger safety lever when you are not spraying. Be sure to
read all warnings concerning the high pressures of airless
spraying on page 3.
Pushing the outlet push button will free an outlet valve
that may be stuck with dried residue, thereby allowing the
pump to prime. Do not press the button after the unit is
pressurized since it may damage the push-button valve.
HYDRAULIC PUMP:
The hydraulic pump converts the power of the electric
motor into hydraulic power. An eccentric cam on the
motor shaft moves the piston back and forth, pumping oil.
This hydraulic power distributes pressure smoothly
against a diaphragm. The hydraulic power is regulated by
the pressure control valve. The clicking sound you hear
is the valve releasing the excess power.
PRIME VALVE:
The prime valve knob is located on the side of the paint
pump. When turned to “prime”, it circulates paint to vent
the air trapped in the paint pump out the return hose. It
will continue to recirculate the paint until the knob is
manually turned to the “spray” position.
When the prime knob is turned to “spray”, flow is shut off
through the return tube and is routed to the paint hose for
spraying.
DIAPHRAGM:
The diaphragm is located between the hydraulic pump
and the paint pump. It acts like the heart of the sprayer. It
is moulded from a tough, but flexible polymer plastic that
resists all paint solvents. It serves to transmit the hydraulic power to the paint while keeping the oil and the paint
separated.
The prime valve also serves to relieve pressure on the
system during shutdown and cleanup. The pressure is
relieved by turning the prime knob to “prime”.
The prime valve has another important function. It is a
safety relief valve. If too much pressure builds up in the
sprayer, the prime knob will dump this pressure harmlessly back into the paint bucket.
PRESSURE CONTROL VALVE:
The manually operated pressure control knob is on the
side of the hydraulic pump. When the knob is turned
clockwise, oil pressure is increased. When the knob is
turned counterclockwise, oil pressure is reduced. The
pressure control knob regulates the pressure on the
diaphragm up to 2500 PSI.
Prime valve

Hydraulic
pump
Always reduce the pressure (turn knob all the way counterclockwise) when cleaning or when switching the
position of the prime knob. Running the pump in the
prime position with the pressure knob turned fully counter-clockwise will eliminate any air in the diaphragm
chamber. A small amount of air here will cause low
working pressure or cause the pump not to prime.

Tip chart example: Latex stain is being
sprayed onto a fence.
The paint is fairly thick
(like a very heavy motor oil) and the L-1500
is the spray machine.
The maximum tip is a
.015 for an L-1500.
Draw a line along the
.015 tips as shown
below. Everything
above the line is
sprayable with the L1500. Now just choose
the fan width. For
fences a 6” width will
give a lot of control, so
the intersecting best
choice would be a 315 tip with a yellow gun
filter.

Results are based on water,
heavier viscosities will produce

The two most important things to remember about tips.....
1) Low pressure means longer life, for tips and the pump. Less overspray too!
2) Worn tips waste paint and overwork the pump, causing premature pump wear. The maximum tip for a pump
is the largest tip that will deliver a proper pressure for spraying without overworking or overloading. When a
tip is used for some period of time, it can wear beyond the maximum size recommended for the pump, which
will cause low pressure and poor spray pattern.
• Stains and thick latex products often cause the most rapid wear of the tip, while clear lacquers and varnishes cause the least wear. Thus tip life can vary from as little as 50 gallons to as much as 200 or more,
depending on the product being sprayed and the pressure used.
• Filter screen mesh for the gun or pump are picked not because of the type of paint being used, but to protect
a given size of tip. Pick the tip for the type of paint and job being done and then choose the filter to protect
that tip.

STARTUP PROCEDURE
1. After assembling unit as per previous pages, attach
hose and gun, tighten firmly with wrench. Engage gun
trigger safety lock.
Prime valve
2. Strain and thin the paint. Remove any skin which
may have developed on the paint due to air exposure.
Next, stir and strain the paint (most paints have
particles that will clog filters and spray tips). Most
latex and oil base paints require 5 to 15% thinning.
Note: Always pump compatible thinners through
the system before priming with paint. Use water
for latex and paint thinner for oil base. (incorrect
thinner will jell the paint and jam the pump valves.
If jamming occurs and the following does not get
the pump going, see page 15 cleaning valves).

5. Prepare to prime. Note: Always pump compatible
thinners through the system before priming with paint.
a) Turn pressure knob fully clockwise.
b) Test for suction by placing palm over suction fitting.
See figure 12. If suction is felt, proceed to point 3
below. If no suction is felt, repeat step 3 while
pouring a small amount of thinners into the inlet
valve to lubricate and soften old paint inside the
valve. If it still will not prime, check valve functioning as described under maintenance on page 15.
c) Connect suction and return tubes and place in
paint. See figure 13. Ensure that the swivel seal is
in good condition. The factory seal is rubber, and a
heavy duty teflon seal is also available. See

STARTUP PROCEDURE (CONTINUED)
6. Prime pump. Prime pump with paint until all air is
removed from the system.
a) With controls still in full pressure and prime positions,
let paint circulate through unit for 1 minute. See figure
18. (If paint does not come all the way up the suction
hose, see "notes" below.)
7. Prepare to spray. Make sure hose connections are
tight.
a) Turn pressure knob counterclockwise to “low”. See
figure 19.
b) Turn prime knob to “spray”. See figure 17.
c) Increase pressure by turning pressure knob clockwise. Paint hose should begin to stiffen. If there are
any leaks, relieve pressure and shut motor off
before tightening any loose connections.
A loud clicking sound should be heard when
pressure is built up.

NOTE: Adjust pressure only high enough to
atomize sufficiently. Too much pressure will
result in excessive overspray and accelerate tip
and valve wear.
8. You are now ready to spray! Prepare spray gun ...
Unlock Trigger (Always lock trigger when not
spraying). Be sure to practice on some scrap
cardboard or wood before proceeding on your
job.
a) Pull out trigger lock on spray gun and turn. See
figure 20.
b) Be sure the reversible tip is turned to the “Spray”
position before pulling the trigger. See figure 21.

TO TURN UNIT OFF . . .
Always reduce pressure, slowly turn prime knob to prime,
trigger gun (in safe direction) to release pressure build up
in hose, and turn motor off.
AFTER ONE HOUR OF USE...
re-tighten the block bolts (in order from 1 to 4 as shown in
block diagram at the top of the previous page) using the
1/4 Allen wrench provided. Thereafter, tighten the bolts
every three to four operations. Be sure to wait until the
sprayer has cooled down to room temperature before
tightening the bolts.

THICK PAINT...
If paint does not come all the way up the suction hose,
check all suction hose connections to be sure no air is
getting in the system. If unit still does not prime, stop and
start the motor 3 or 4 times to help the pump complete
priming. Prime knob must be in "prime" position.

HINTS FOR AIRLESS SPRAYING
••You can learn to spray paint as easily as you can learn
to paint with a brush and roller. Get professional looking
results by following the spray tips below.
WARNING: DO NOT BEGIN SPRAYING BEFORE
READING THIS SECTION AND ALL PREVIOUS
SAFETY INFORMATION.
1. KEEP THE GUN PERPENDICULAR TO THE SURFACE:
Always hold the gun perpendicular to the surface with
the tip approximately 12" from the surface. If held at
an angle (up and down or side to side) paint will build
up unevenly and leave the work splotchy. (See figure
22).
2. MOVE WITH A SMOOTH ARM STROKE:
Move the gun at a steady even pace while keeping
the gun perpendicular to the surface. (See figure 23)
Do not move the gun by flexing your wrist. Fanning
the gun will cause excessive overspray and uneven
coverage. (See figure 24).
Figure 22. - Right and wrong way to hold spray gun.
3. START MOVING THE GUN BEFORE TRIGGERING:
To get smooth overlap and prevent initial paint
buildup, start your stroke movement before pulling the
trigger. At the end of the stroke release the trigger
before stopping.
NOTE: To assure uniform paint coverage, overlap
each stroke by 40% - 50%.
4. INTERMITTENT USE:
If you are spraying and decide to stop for several
minutes, lock the spray gun trigger and submerge the
tip in a container of the appropriate solvent. This will
prevent paint from hardening in the tiny spray opening and clogging the tip. Be sure to release the
pressure by turning the prime knob to prime and
switching off the pump.

CLEANING INSTRUCTIONS
NOTE: We recommend running light oil or mineral spirits
through the unit before storing. When using latex paints,
make sure the unit has been completely cleaned before
storing with mineral spirits. Mineral spirits react with latex
paint to form a jelly-like substance which can damage
your pump.
As with all spray equipment, your sprayer must be
cleaned properly or it will not operate properly. Clogged
valves and filters are the most common causes of problems. If followed, these guidelines will insure trouble free
performance from your sprayer.
CAUTION: Clean with water if latex is used. Clean
with paint thinners for oil based paints. Both water
and paint thinner will be refered to as "solvent" from
here on in.
WARNING: Do not clean the spray gun unless the
pressure has been released from the system. See
page 3 for further precautions.
1. Turn prime/spray control to “prime” position.
2. Turn pressure control fully clockwise to “high pressure” position.
Engage trigger lock.
3. Turn power switch to ON position.
4. Lift suction assembly above paint level in bucket. Allow pump to run
until the majority of paint is exhausted from pump. (see figure 25 & 26).
5. Pump solvent. With the pump still running, immediately place both the
suction assembly and by-pass tube into an appropriate solvent. Allow
pump to prime and circulate for ten minutes.
6. Clean suction system and filters. While fluid is circulating, wipe
suction assembly and by-pass tube with a rag. (see figure 28). Also,
remove suction filter with pliers. Wipe inside of suction filter-housing with
a rag. Clean suction filter in a separate container of fluid and then
reinsert into suction filter housing.
7. Pump air out. Allow the solvent to circulate for an additional minute to
ensure all air has been exhausted from the pump.
8. Turn prime/spray control to “spray” position, and reduce pressure.
9. Rotate spray tip to the “cleaning” position.
10. Flush system. Release trigger lock. Point spray gun into an empty
waste bucket and pull the trigger (or spray remaining paint in hose back
into paint pail). Spray at least 1 gallon of fluid into waste bucket. To
reduce splashing, direct the fluid stream along the inside of the bucket at
a side angle and well above the fluid level. (see figure 27). Warning:
conductive metal containers must be used when flushing flammable fluids through the system. Always flush at low pressure with
spray tip in cleanout position. A metal part of the spray gun must
be held firmly against the grounded metal pail when relieving the
pressure from the gun.
11. Repeat steps 1,5-8,10 & 11 with fresh solvent.
12. Turn the prime/spray control to the “prime” position.
13. Turn the pressure control fully counterclockwise to “low pressure/
hydraulic bleeding” position.
14. Turn power switch to OFF position.
15. Release any remaining pressure.With the gun pointed in a safe
direction, pull the gun trigger with the trigger lock disengaged. Engage
trigger lock.
16. At this point the pump and spray gun are clean, but still require
preparation for storage. Spray tip guard or any accessories being used
still require cleaning.
17. Storing unit for more than 3 days. If unit was cleaned with an oily
paint thinner such as varsol, the unit is now ready for storage. If unit was
cleaned with water or a strong thinner (ie. lacquer thinner) pump varsol
(or mineral spirits) through the entire system by repeating step 11, 12,
13, 14, & 15.. If varsol is not available, drain all the solvent out of the
hose, gun, and pump. (Tungsten carbide parts in the valves will corrode
if left in water for long periods of time). With the pump running in the
prime mode, place a few drops of light oil in the inlet valve. Let the pump
run until it spits oil drops out the return fittings. This will displace any
remaining solvent and lubricate the valves for storage. (see figure 29).

MAINTENANCE & SERVICE
WARNING: TURN POWER OFF AND RELEASE ALL
PRESSURE FROM THE UNIT BEFORE DOING MAINTENANCE.
NOTE: All valves contained in your sprayer are one piece
cartridge valves. To change, simply unscrew the worn
valve and replace with a new one; there are no component parts. Follow torque specification guidelines provided for each valve.
INLET AND OUTLET VALVES:
The inlet and outlet valves will wear. The rate of wear
depends on the type and quality of paint you use. As the
spraying pressure and vacuum drop, the outlet valve and
inlet valve cartridges should be replaced. Average life
expectancy is 200 gallons for the outlet valve, and 400
gallons for the inlet valve. However, first be sure that the
tip is not worn; this can cause a drop in spraying pressure
as well. New valve cartridges should be installed with new
washers and torqued to: inlet valve 21 ft/lbs., outlet valve
12 ft/lbs. (outlet valve push button, 5 ft/lbs).
Checking valves:
• Inlet valve: remove and fill with thinners, watch rate
of leaking. Slow dripping is ok, but fast dripping is
not. Usually a good cleaning is all that is
neccessay.
Important: be sure to reinstall the nylon seal
before installing the valve. Once the unit is operating, a more accurate test can be done by turning
the motor off under full pressure. Then turn the
motor on for 2 seconds - No more. If it does not
start, the inlet valve is good. If the unit starts, the
inlet valve is worn and needs replacing.
• Outlet valve: remove, and shake moderately while
listening. Any rattling noise is the ball moving
without the tension of the spring. This indicates
valve requires replacing.
Cleaning valves:
Remove both valves from pump and clean using a
brush and compatable thinners. If dried paint is a
problem, soak the valves in a strong lacquer thinner
(remove the outlet valve o-ring before soaking).
Compressed air is very helpfull in blowing out the
softened paint after soaking. Once cleaned and
reinstalled, follow "startup procedure" on page 11.
PAINT HOSE:
Periodically inspect the paint hose. If the hose is kinked,
cut, or worn, it must be replaced . It cannot be repaired. A
hose bursting at 2500 psi can cause significant damage
to property AND cause a serious injury if the spray injects
the skin. Replace with a grounded or conductive airless
paint hose that is rated for at least 2500 psi “working”
pressure.
PRIME VALVE:
If the prime valve is not properly cleaned after each use,
It may stick open. If this occurs, paint will flow through the
return hose when the valve is turned to “spray”. Working
pressure will then slowly begin to drop as the valve
wears. A new valve should be installed with new washers
15
and torqued to 8ft/lbs.
PRESSURE CONTROL VALVE:
The pressure control valve is preset at the factory for your
safety and is not adjustable except by a Lemmer service
center. This valve generally does not require replacement
unless tampered with. However, the valve is easily
replaced. If the pump cannot pressurize to 2500 +/- 250
psi when the gun is not triggered and there are no leaks
or flow through the prime valve, and both the inlet and
outlet valves are in good condition, a new pressure valve
cartridge should be installed with a new washer and
torqued to approximately 4 ft/lbs. Note: turn knob to
minimum before removing to prevent valve from coming
apart.
DIAPHRAGM:
After the first hour of operation, it is important to check
the torque of the four (4) bolts holding the valve block
assembly and diaphragm. Check the torque using a cross
pattern (from 1-4) to 23 ft/lbs, see figure 32.. If oil is
leaking past the diaphragm and retightening does not
stop the leak, the diaphragm must be replaced.
If paint has contaminated the oil reservoir, all components
of the hydraulic system must be thoroughly cleaned and
the diaphragm and oil replaced. We recommend this work
to be performed by an authorized service center.
OIL LEVEL IN PUMP HOUSING:
The oil reservoir in the pump housing is sealed and
should not require maintenance. However, if oil leakage
has been noticed and the pump is having difficulty priming, the oil level should be checked. Remove the face
plate. The oil level should be 1/4" (1 cm) from the top of
the housing. Refill with Nuto H 32 hydraulic oil.
SPRAY GUN:
The tip filter should be cleaned or replaced after each use
to minimize tip clogging problems. If the gun valve becomes worn and begins to leak, it should be replaced.
SPRAY TIP:
The spray tip is one of the most important elements in
producing a quality spray job. It requires periodic replacement (every 50-100 gallons) to maintain performance and
to prevent overworking the pump (see pages 9 & 10 for
details).

GAS DIAPHRAGM
It can be used to transfer paint to remote locations, or
directly to high pressure pumps. At a 1:1 ratio with up to
125 PSI air pressure it can also supply numerous air
guns.
These sprayers are the same as the electric diaphragm
pumps, but with the advantage of a gas engine. All use
Honda motors and the time proven belt drive system.
HVLP TURBINE & VENTURI UNITS
High Volume Low Pressure sprayers are used for fine
finishing where overspray must be kept to a minimum.
The finish results are equal to or better than conventional
air spray. The turbine systems are self contained and do
not require an outside air source. The VENTURI spray
gun only uses about 8 CFM of shop air. Applications vary
from automotive finishing to commercial multi-color
architectural coating.
ELECTRIC PISTON PUMPS
Suitable for heavy coatings on large jobs. Its innovative
pump design is driven by a DC motor.

TROUBLESHOOTING
Provided you have followed the instructions, the sprayer will operate efficiently and give trouble-free service. Should
any unexpected problem arise you can, in most cases, remedy the problem by following the chart below. If you find
that you cannot correct the problem, then take the sprayer to your nearest authorized service agency. Many of the
“causes” listed are unlikely to happen. However, all are included in an attempt to cover every possibility.
IT IS ABSOLUTELY ESSENTIAL FOR TROUBLE-FREE OPERATION THAT YOUR AIRLESS SPRAYER BE KEPT
CLEAN AND FREE OF RESIDUAL PAINT BUILD-UP ON THE INTERNAL PARTS. IT MUST BE CLEANED AND
LUBRICATED AFTER EVERY USE.
