INTRODUCTION
CONGRATULATIONS on choosing a new Lemmer Spray
System! Your Lemmer Spray System is exceptionally
rugged in construction and designed to operate with the
best possible delivery efficiency. Like any fine precision
tool, its most efficient operation depends on a thorough
knowledge of its operation capabilities and maintenance.
With proper material preparation and maintenance, your
Lemmer will produce beautiful, uniform finishing results for
years to come.
This manual covers a variety of air spray equipment which can
be categorized as follows:
Your Lemmer system is capable of spraying a wide
variety of lacquer, some epoxies, industrial finishes, latex,
oil-based and alkyd paints, as well as stains, preservatives and other architectural coatings. 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 system until you feel comfortable using it.
COATING APPLICATIONS

AIR SPRAY GUNS - HVLP:
The A-711 / A-928 / A-930 which atomize paint at 2 - 10 psi.
The lower operating pressure provides lowest possible overspray mist with high speed application rates.
PRESSURE FEEDING THE AIR GUNS:
Advantages:
• The spray gun can operate in any position, and fit in
smaller areas.
• The weight of the material is off the spray gun for less
operator fatique.
• A wider range of viscosities may be used with the same
fluid nozzle.
• Generally can increase application rates and reduce paint
mist.
• Saves time by requiring less fills.
Fluid supply method:
Lemmer pressurized containers are available in 2 quart
remote, or 2.25 gallon remote. They are inexpensive and
simple to operate.
Lemmer low pressure pumps are available in two styles.
The Boxer 5 is perfect for supplying constant steady
pressure to multiple air spray guns. The Boxer 24 is not
recommended for air gun supply but is for use as a transfer
pump.

Figure 2. - Typical 2 1/4 gallon system
DESCRIPTION:
The following paragraphs refer to the 2 1/4 gallon system.
The 2 quart system is basically the same other than size
and not having a standard air regulator for the air cap air.
The Lemmer pressure pot is designed for production line
and decorator painting applications using internal or
external mix spray guns. The pressure pot is capable of
holding bulk quantities of paint or a one gallon paint can
may be placed in the pressure pot without having to pour
out can contents.
Basic construction of the unit consists of a heavy deep
drawn one piece galvanized steel pot, steel stamped pot
lid, eyebolt clamp.
The unit is equipped with a pressure regulator, gauge,
safety relief and bleeder valve, paint line and air line
connections. A convenient carrying handle allows attachment of the unit to the rung of a ladder or scaffolding to
facilitate house or barn spraying operations.
SPECIAL SAFETY PRECAUTIONS:
• Do not pressurize pot over 50 PSI.
• Make sure all feed line, eyebolts and spray guns are
secured before turning air supply on.
• Always shut off air pressure at source and bleed off
all pressure in pressure pot by gently pulling safety
valve ring before loosening knobs.
• Regularly check to be sure gauge and regulator are
functioning correctly. Also check that no paint nor
other deposits are in safety valve inlet. In the event
more than 50 PSI is applied to the pressure pot, and
safety valve is clogged, the higher pressure could
damage the pressure pot.
• Only use original Lemmer replacement parts. These
parts are safety performance engineered. Any substitutions may be counter-protective and dangerous.

SPECIFICATIONS - BOXER 5 & 24
PUMP TYPE:
Example:
Pump ratio= 1:1
Air pressure reading at air motor control= 71 psi
Max. fluid pressure (1 x 71)= 71 psi
The air is connected to the air motor of the pump. First, the
pump is primed, then the pressure is set (lets say at 10 PSI for
pumping latex). When the fluid pressure reaches 10 PSI in
the hose, the:
Boxer 5 pump cycles feely, waiting to deliver more fluid without
delay. This uses about 2 cfm of air, but provides instant trigger
response thus eliminating fan fluctuations.
Boxer 24 fluid pump parts (including air motor) stop moving
creating a stall position. When the flow valve is opened and the
fluid pressure begins to drop, the air motor and fluid pump
immediately begin to work to maintain pressure. The results are
minimal air consumption and minimal all-around wear.
These units are AIR POWERED DOUBLE DIAPHRAGM
PUMPS. Top quality parts keep maintenance to a minimum. All
paint valves are made of stainless steel for extra long abrasion
resistance. The advantages of this type of pump is:
Minimal or no thinning of paint products
Pumps straight out of original paint container
Variable pressure
Boxer 5 is quiet running & and continues running even
when spraying stops to insure constant spray pressure
Boxer 24 is quiet running & and stops when flow stops. It is
best suited for transfering liquids
Safe for hazardous locations - no electricity
How Pneumatic pumps operate: A pneumatic pump consists
of a reciprocating air motor and a fluid pump. Its speed and
pressure are controled by air regulator. The pressure ratio
(pump ratio) of the pump is determined by the square area of
the air motor piston versus the square area of the piston in the
fluid pump. The pumps maximum possible output pressure is
determined by multiplying the ratio by the compressed air
pressure fed into the air motor.

regulator
Fluid outlet fliter

PUMP COMPONENTS:
Spray Gun: The spray gun is supplied separately and may be
of a standard high pressure air design, or of the HVLP low
pressure design.
Air motor: These specially designed air motors convert the
energy from compressed air into a double action stroke. Both
the left and right power strokes are used by the fluid pump to
create pressure and volume. The air motors are permanently
lubricated and require minimal maintenance. Its air source must
be regulated, clean, and free of oil.
Fluid Pump: The fluid pump is a double diaphragm with inlet
and outlet valves on each side. The diaphragm is made of a
tough nylon resin blend and the housing of polyarilammide
material for best chemical and abrasion resistance.
Pressure regulator: The pressure regulator is on the top of the
air motor. When the regulator handle is turned clockwise, air
pressure is increased, when the handle is turned counterclockwise, air pressure is reduced.
Always reduce the pressure (turn the handle all the way
counterclockwise, or disconnect air supply) when cleaning or
when switching the position of the dump valve (if so equipped).
Dump Valve (if equipped): The dump valve is located on the
side of the fluid pump. When turned to “prime” (handle in-line
with body), it circulates fluid to vent the air trapped in the fluid
pump out the return hose. It will continue to recirculate the fluid
until the knob is manually turned to the “spray” position.
When the dump valve is turned to “spray”, flow is shut off
through the return hose and is routed to the fluid hose for
spraying or transferring.
The dump valve also serves to relieve pressure on the system
during shutdown and cleanup. The pressure is relieved by
turning the prime valve to “dump”.

Most types of paints and coatings are supplied ready to spray
(with the exception of possible thinning). In possible instances
where a coating is contaminated with foreign particles, Boxer
units are available with inlet filter screens, and a high pressure
outlet filter to prevent possible plugging or damage.
Viscosity alone is no measure for good pump priming,
pumpability or sprayability. It may well be that a suction hose
has to be exchanged for a straight suction tube, or a shorter
tube to assist the priming action.
Two-component materials generally have a short “pot life”. The
unit must be properly flused and cleaned well before the curing
time starts.
Pumping coarse bodied or aggressive fluids is possible up to
about 3mm maximum diameter particles.

SPECIFICATIONS - PRESSURE POT
DESCRIPTION:
The Lemmer paint tank is designed for production line
and decorator painting applications using internal or
external mix spray guns. The tank is capable of holding
bulk quantities of paint or a one gallon paint can may be
placed in the tank without having to pour out can contents.
Basic construction of the unit consists of a heavy deep
drawn one piece galvanized steel tank, steel stamped
tank lid, eyebolt clamp.
The unit is equipped with a pressure regulator, gauge,
safety relief and bleeder valve, paint line and air line
connections. A convenient carrying handle allows attachment of the unit to the rung of a ladder or scaffolding to
facilitate house or barn spraying operations.
Figure 5. - Typical pressure pot system
Special safety precautions:
• Do not pressurize tank over 50 PSI.
• Make sure all feed line, eyebolts and spray guns are
secured before turning air supply on.
• Always shut off air pressure at source and bleed off
all pressure in paint tank by gently pulling safety valve
ring before loosening knobs.
• Regularly check to be sure gauge and regulator are
functioning correctly. Also check that no paint nor
other deposits are in safety valve inlet. In the event
more than 50 PSI is applied to the tank, and safety
valve is clogged, the higher pressure could damage
the tank.
WARNING: Failure to follow instructions on proper
assembly and use of a paint tank may possibly result
in damage to property or personal injury. This unit
must be assembled as indicated in these instructions. Only those parts supplied with this unit should
be used. These parts are safety performance engineered. Any substitutions may be counter-protective
and dangerous.

A-711 HVLP SPRAY GUN WITH PRESSURIZED CUP:
As high speed compressed air passes through the venturi
assembly, a low pressure field is created. Ambient air
(outside room air) is pulled through the air filter/silencer,
mixing with the compressed air, and creating a high
volume of low pressure air. Operating at standard air line
pressures the A-711 venturi gun creates less than 10 psi
at the gun while maintaining 65 - 95% transfer efficiency.
Special safety precautions:
The A-711 venturi gun is a non bleeder type with continuous pressure in the cup, even after the air line has been
disconnected! Do Not pull trigger after spraying!
Release pressure with the cup locking lever immediately
after use. Wear eye protection!

PAINT PREPARATION & SELECTING THE PROPER FLUID SET
2. Stir paint completely and strain.
3. Use the viscosity cup to measure paint as follows:
a) Submerge the Lemmer Viscosity cup in the paint.
b) Lift the cup out of the paint and begin timing.
c) Stop timing when the steady paint stream is first
broken.
d) The time recorded is the paint’s viscosity.
4. Now read the nozzle chart included with the spray
guns parts list and choose the nozzle which lists the
viscosity range your material falls into.
FLUID SET SELECTION:
Nozzle sets range in size to provide different fluid flow
rates. For low flow rates or light viscosity fluid, select the
smaller nozzle sizes. For high flow rates or high viscosity
fluid, select the larger nozzle sizes. For the best atomization, use the fluid nozzle that will give the required flow
with the needle fully triggered.
Note: The nozzle chart has been made as accurately as
possible. Not all paints will exactly comply due to paint
ingredient variations. However, it is an excellent starting
point for learning the basics spray painting.
Measuring paint viscosity:
1. Thin paint according to paint can instructions. Be
certain to use a thinner which is compatible with paint
used. If no thinning instructions are given, a general
rule of thumb is 5 to 15% thinners. (fine finish up to
35%)
Thin Materials: Decrease air flow through gun to minimize mist.
Heavy Materials: If flow rate is too slow, additional
thinning will be needed or a larger fluid nozzle will be
required.
PROPER SPRAYING TECHNIQUES
Get professional looking results by following the spray
tips below.
4. 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.
1. Adjust air line pressure to 50 psi to start. Test the
spray pattern, atomization, and overspray mist and
adjust pressure up or down to obtain desired results.
2. Keep the gun perpendicular to the surface. Always
hold the gun perpendicular to the surface with the tip
approximately 6 to 8" 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. This also
saves material and reduces mist.
3. Move with a smooth arm stroke Move the gun at a
steady even pace while keeping the gun perpendicular to the surface. (See figure 8) Do not move the gun
by flexing your wrist. Fanning the gun will cause
excessive overspray and uneven coverage. (See
figure 9). If the rate of speed is not comfortable for
you, select another nozzle/needle size according to
the nozzle charts.
NOTES:
For a nice even finish, always overlap previous strokes
by the same amount, generally 50%. Put on a full wet
coat whenever possible.
When blending spots, work from the outside in. Start one
inch out, no dusting. This eliminates “chronic halo” .

6. Pour about 1/2 gallon of paint solvent into the pot.
Use the correct type of solvent for the paint being
used: mineral spirits for oil base paint, lacquer thinner
for lacquer base paints, warm soap water for Latex,
etc.
7. Clamp lid onto pot and proceed to spray the proper
solvent through spray gun and hose.
8. Proceed to remove all thinner from hose in accordance with steps 1 thru 9 in this section.
9. Clean lip of pot, groove pot cover, and gasket.
CLEAN PAINT POT AS FOLLOWS:
IMPORTANT: It is very important that the fluid material hose and spray gun be cleaned as soon as the
spray job is completed.
1. Shut off air to the pot at air pressure regulator by
turning adjusting screw counter clockwise.
2. Gently pull safety valve ring to purge air from pot.
Note: if equipped with agitator accessory, be sure to
stop propeller before venting or opening lid.
3. Completely cover spray gun nozzle with a soft rag
and with air lines pressurized, pull trigger of the gun.
This will force paint remaining in the material hose
back into the pot.
4. Remove pot lid and pour any remaining paint back
into original containers for future use.
5. Using a clean, dry cloth, wipe inside area of pot
clean. A replacement plastic liner is #L011-586.
CLEAN SAFETY VALVE AS FOLLOWS:
Remove safety valve and clean port (orifice) periodically.
Accumulations of paint in the port can prevent proper
valve action. Do not disassemble valve or change settings.
CAUTION: This component has been factory calibrated and sealed. Do not attempt to disassemble
valve or alter calibration.

CLEANING INSTRUCTIONS - BOXER SYSEMS
As with all spray equipment, your spray system 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 spray
system.
Warning!
Figure 14. Pump until clean solvent appears.
Warning: conductive metal containers must be used
when flushing flammable fluids through the system.
Always flush at low pressure with atomizing air
turned off. A metal part of the spray gun must be held
firmly against the grounded metal pail when flushing
or relieving pressure from the gun.
6. Pump solvent out by lifting the suction hose out of the
solvent. Turn pressure regulator to minimum and
trigger gun to release system pressure and disconnect air supply.
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.
CLEAN-UP:
To get the best use and longest life from your spray
system, it is very important to clean it out properly. The
procedure is simple and is very similar to the flushing
procedure performed earlier. Cleaning and flushing would
also be required when changing color, or type of paint, ie:
latex changing to oil base.
1. Turn pressure regulator to minimum, trigger gun into
waste pail to release all system pressure.
2. Lift both suction tube above the level of paint in the
pail and turn pressure up to a slow cycle rate. Trigger
gun to allow unit to pump out paint.
Figure 15. Fluid is pumped out.
7. Follow above steps 1-6 using clean solvent to
completely flush system. You may at this time, if you
wish, blow compressed air into the tip (gun trigger
open and air supply disconnected) to push the solvent all the way out the fluid nozzle.
8. If changing paint types, ie: latex (water base) to oil
base, you would have to flush system with clean
mineral spirits using above steps 1-6. This would
prepare the pump for the oil base paint. Water would
have to be used as a last flush if changing from oil
base paints to latex.
9. Ensure pressure regulator is turned to minimum
and all pressure is released. Turn pump air supply
OFF.
10. Brush gun clean with appropriate solvent. Inspect
filters for pinholes, plugging, or other damage. Replace if required.
11. Remove intake screen on suction tube and brush
clean, re-install.
12. Storing unit for more than 3 days. If system was
cleaned with an oily paint thinner such as varsol, it is
now ready for storage (after step 13). If system was
cleaned with water or a strong thinner (ie. lacquer
thinner) pump varsol (or mineral spirits) through the
entire system by repeating step 7. If varsol is not
available, drain all the solvent out of the hose, gun,
and pump. (metal parts in the valves will corrode if
left in water for long periods of time). With the
pump running in the prime mode, place the suction
tube in a container of light oil. Let the pump run until it
spits oil drops out the gun nozzle. This will displace
any remaining solvent and lubricate the valves for
storage.
13) Coil up spray hose, inspecting for signs of damage.
Figure 12. Pump fluid out.
3. Place suction tube into pail with proper solvent to
flush out paint and allow unit to prime in the solvent.
Clean the outside of suction tube.
Figure 13. Clean pump with suitable solvent .
4. Turn pressure regulator to minimum and close
gun.
5. Spray with atomizing air still turned off and starting
with minimum pressure, aim gun into paint container
and hold trigger open until paint flow stops and
solvent flow just begins. Release trigger. Aim gun into
solvent pail and circulate solvent for about two
minutes. To reduce splashing, direct the fluid stream
along inside of bucket at a side angle and well above
the fluid level.Release trigger. Point spray gun into an
empty waste bucket and spray at least 1 gallon of
fluid into it. (see figure 14).

CLEANING INSTRUCTIONS - ALL AIR GUNS
As with any spray equipment, your sprayer must be
cleaned properly or it will not operate properly. If
followed, the following guidelines will insure trouble
free performance from your sprayer.
A-900, A-928, A-930, A-711:

cup and add about 1" clean solvent. Attach cup to gun
and swirl it around while spraying. Remove cup and pull
trigger to break air lock in material tube. Empty balance of
solvent from cup and repeat process with clean solvent.
Remove cup and wipe clean. Clean gun body with a
solvent dampened cloth. Remove air cap and clean with
solvent and brush. Do not use a hard metal object which
might damage the air cap holes.
CAUTION: Clean with water if latex is used. Clean
with paint thinners for oil based paints. Both water
and paint thinner will be referred to as "solvent" from
here on in.
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.

VENTURI ADJUSTMENT:
Refer to parts diagram in back of manual. Be sure venturi
is fully seated into the gun handle and that the locking
screw is tight.
1. If air fails to shut off when trigger is released, loosen
locking nut (67) and turn adjustment cap (66) clockwise. This will allow venturi spindle to fully restore.
2. If air flow fails to start before fluid needle moves,
loosen locking nut (67) and turn adjustment cap (66)
counterclockwise.
FILTER/SILENCER MAINTENANCE:
The filter must be in place while spraying. This will
prevent recirculating spray mist through the gun. The
filter must be kept as clean as possible to allow full air
flow through the spray gun. To clean, remove filter and
brush with lacquer thinner.
MAINTENANCE - PRESSURE POT
Caution: If the 2 quart remote cup is accidentally
tipped over or held at too great an angle (or any other
pressure pot), fluid might leak into the regulator. In
the event this happens, clean immediately.
Periodically inspect the tank for leaks around the paint
tank lid. If leakage is present, remove the paint tank lid
and clean lip of tank and groove in tank lid. Replace
gasket.

categories. There are small units for
spraying a house or barn once a year,
and large units for spraying warehouses
on a continuous basis.
ELECTRIC DIAPHRAGM
TRANSFER PUMP
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 above
piston pumps except in a lower cost
diaphragm design. The motor runs
continuous for the ultimate spraying
pressure control. Hopper models are
easiest to clean.
18
GAS DIAPHRAGM
These sprayers are the same as the
electric diaphragm pumps, but with the
advantage of a gas engine. All use
Honda motors and belt drive systems.
LINEMARKERS
Designed to handle the abrasive nature
of road marking paint. There are three
sizes of walk-behinds, and some are
available with two or more guns. Custom
systems are also made to order depending on the requirements.

Shown here is the old

The Venturi version gun, when used with a
clean venturi filter, gives a very high airflow at
the aircap, relative to the incoming air from the
compressor. This is a feature unique to Lemmer.
A good way to compare the venturi gun to the
turbine units is as follows:
The venturi gun with 40-45 psi of incoming air
gives the same performance as the T-55 (aircap
atomizing pressure). With 60-65 psi of incoming
air gives the same performance as the T-95.

Pressure feed air cap note:
The H2 air cap works well for normal pressure feed
applications. For first time buyers who want the better
atomization but do not want to buy a needle kit, we will
keep a special order stock of E21P air caps. We will
also keep a special low price on them.
Order # L015-505 E21P air cap.
(Exchange for H2 cap is allowed when neccessary)

2-1/4 GALLON PRESSURE POT PARTS LIST & DIAGRAM
Shown with
agitator option.

Hint about pressure setting:
A good general rule to follow is that if the
pot pressure (in a pressure feed
environment with 25 ft line) has to be set
higher than 15-20 psi to get a decent hand
speed, it is best to go to at least one needle
size up. At high pot pressures, with ANY air
gun, there will be a lot of non-atomized
material in the center of the spray pattern.
Due to the low aircap pressures of HVLP
guns in general, this problem is less
pronounced with the A-900, which is why it
is suggested for general purpose use.
CAUTION: Make certain
that all pressures within
the system are relieved
before attempting to
remove any component or
part of a component.
