WARNING
1) Do not spray paints or other inflammable fluids
indoors which have a flash point below 21 degree
C, 70 degree F. Keep spray area well ventilated.
Before spraying, turn off all pilot lights and open
flames.
2) Wear a respirator which is approved for the
product being sprayed.
3) Do not use halogenated hydrocarbon solvents
in this system; it contains aluminium parts and
may explode. Cleaning agents, coatings, paints,
and adhesives may contain halogenated hydrocarbon
solvents. Don't take chances, consult your
material supplier to be sure. (ex: methylene
chloride and 1,1,1 - Trichlorethane)
4) Caution: When a flammable liquid is sprayed
there may be danger of fire or explosion
especially in a closed area.
5) Caution: Arcing parts. Keep the compressor at
least 20 feet away from explosive vapours.
6) Caution: Static electricity can be developed by
spraying. Ground unit and object to be sprayed.
On electric units, unit power cord must be connected
to a grounded outlet. Use only three wire
extension cords. Static explosion can occur with
ungrounded unit.
7) Always follow safety precautions and warnings
printed on paint container.
8) Do not pull on hoses to move equipment, DO NOT
kink or bend the hose sharply.
9) Keep children or anyone not familiar with air spray
systems away from equipment and work area.
10) Conductive metal containers must be used when
flushing flammable fluids through the system.
Always flush at low pressure with spray tip removed. A
metal part of the spray gun must be held firmly against
the grounded metal pail when flushing or relieving
pressure from the gun.
SAFETY PRECAUTIONS
ATTENTION
1) Ne jamais pulvériser à l’interieur un produit inflammable qui a
un point éclair inférieur à 21 degrés C,70 degrés F. L’endroit où
vous peinturez doit toujours être bien aéré. Avant de pulvériser
s’assurer qu’il n’y a aucune flamme ou pilot (veilleuse) de fournaise
en marche dans l’appartement.
2) Servez-vous d’un masque respiratoire qui est certifié pour le
produit que vous pulvérisez.
3) Ne pas utiliser de solvants contenant des hydrocarbures
halogénés avec ce matériel. Il contient des particules d'aluminium
et peut exploser. Les agents de nettoyage, enduits, peintures et,
adhésifs, peuvent contenir des solvants contenant des
hydrocarbures halogénés. Soyez prudents; consultez votre
fournisseur pour les informations nécessaires. (ex: méthylène
chloride and 1,1,1 - Trichloréthane)
4) Attention: La pulvérisaton d'un liquide inflammable peut entraîner
un risque d'incendie ou d'explosion, surtout dans les espaces
fermés.
5) Attention: Étincelles électriques. Ne pas placer la compresseur à
moins de 6 mètres des vapeurs explosives.
6) Attention: La pression du produit que l’on pulvérise peut produire
une charge électrostatique. Mettre le matériel et l'objet à
pulvériser à la terre. Sur les modèles électriques, le cordon
électrique doit être attaché à une prise de courrant reliée à terre. Le
cordon de rallonge doit être à 3 fils. Des décharges d'électricité

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:
AIR SPRAY GUNS - CONVENTIONAL:
The A-900 which atomizes paint at 40 - 60 psi. The higher
operating pressure results in the best possible finish.
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.
COMPRESSOR REQUIREMENTS FOR MOST OF THESE
SYSTEMS:
For optimum results the air compressor should maintain a
constant minimum air flow of 7 cfm at a minimum of 50 psi. Air
supply must be clean, dry, and oil free.

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.
Figure 2. - Typical 2 1/4 gallon system
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.

PUMP TYPE:
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.

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.
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”.
COATINGS:
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.

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.

Important: A pressure
regulator must be used
between the air

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
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.
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%)
Get professional looking results by following the spray
tips below.
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.
PROPER SPRAYING TECHNIQUES
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.
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.
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.
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.
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” .

OPERATING INSTRUCTIONS
Whenever the system is to be used, it must be prepared
for the type of paint to be used. This requires the
system to be flushed out with an appropriate solvent
(water for latex, mineral spirits for oil base, etc.).
Incorrect flushing can cause gumming and priming
problems.
Caution: Never aim spray gun at any part of the body.
Even when air line is disconnected, the spray gun may
retain fluid pressure.
Note: if using agitator accessory, set air control valve
to slowest speed that air motor will operate. This will
ensure proper mixing without splashing and aerating.
7. Set the vertical/horizontal spray pattern:
On A-900, A-925, A-930: loosen the air cap ring,
rotate the air cap, and re-tighten the ring.
On A-711: just turn the air cap. The aircap adjusting
ring only requires to be loosened if it is set to its
widest pattern (srewed in tight).
Caution: Never use metal implements to clean out
holes in the air cap or fluid tip.
Caution: Before servicing the gun always shut off air
and fluid supply and relieve all pressure.
Warning: Be certain that the air line supply line is at
zero psi and pressure regulators are turned to minimum
before connecting any air supply!
1. Securely connect either suction pot, gravity pot, or
pressure feed hose. If using the suction pot have the
bent suction pipe aiming forward (or backward if
spraying upwards). Connect the "zero pressure" air
line.
2. Adjust the volume knob on gun counter clockwise
until full trigger movement is achived.
3. Prepare your paint and pour into the paint container.
It is normal to thin products for air application 10-20%,
depending on manufacturers recommendations and job
particulars.Thicker products require more air pressure
for atomization, larger nozzle sizes, and higher material
pressures. Prepare the surface to be painted according
to the paint suppliers instructions.
4. Practice on scrap material before proceeding to spray.
5. Set the atomizing air pressure. The best pressure for
any type of spraying is the lowest pressure that will
give a good finish. This is because lower spraying
pressures have less overspray. Depending on the type
of paint and its thickness, this pressure will range from
40 - 80 psi.
6. If using a pressure feed system, adjust the paint
pressure to about 5 psi. The material or "pot" pressure
determines how much paint comes from the gun, i.e.)
how wet is the coat. Best material pressures are
between 5- 20 psi. (The gun can be fed from any
pressure pot, or from any transfer pump system with a
1:1 ratio).
Be careful not to overpower the ability of the gun to
atomize properly by using too much fluid pressure. To
test for proper fluid pressure, disconnect atomizing air
to the gun (by use of separate regulator, shut off valve,
or simply by kinking the hose if air is regulated at the
compressor) and pull trigger of spray gun fully, the
material stream should travel 12" to 18" in a downward
arch. Increase or decrease the regulator pressure as
necessary to obtain proper material flow.

Figure 10. - Spray pattern control (turn air cap).
8. Set the spray fan width:
On A-900, A-925, A-930: use the knob at the side of
the spray gun head, or at the back of the gun. Turning
the knob in reduces the spray fan size, turning it out
increases fan. The practical limit is about an 8 - 10 "
fan one foot from the gun (will also adjust down to very
small round spray pattern). Note: The air consumption
decreases as you reduce the fan width.
On A-711: turn the control ring in (for wide) or out (for
narrow). Smoother finishes can be obtained by using a
narrow pattern. More material output can be gained by
using a wide pattern.

Figure 11. - Spray fan width control (A-711 shown).
9. Set the paint volume, use the knob at the back of the
gun to limit the needle travel. As the knob is turned in,
the needle travel is restricted, and material flow is
reduced. (Keep in mind that this restriction will increase
the needle and seat wear). This is for fine
tuning only, the primary control of material flow is the
nozzle size and material pressure.
10. For best paint finish results keep the gun 8 - 12" from
the work piece. Move your gun with a steady, constant
motion to avoid runs, spots, and irregular finishes.

Note: To help prevent paint from entering the vent or
the air hose on the pressurized cup models, refrain
from overfilling the container or tipping the spray gun
at extreme angles.
OPERATING INSTRUCTIONS
Warning for A-711 gun only: Paint cup is under continuous
pressure, even after air line has been disconnected.

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.
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 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.
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.
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.
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).
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.

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.
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.
A-900, A-928, A-930, A-711:
Solvent flushing gun (All models). Empty material from
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.

CLEANING INSTRUCTIONS - A-711 AIR GUN
A-711 ONLY:
Back flush gun. Remove material cup and hold gun over
a shop cloth. Connect air supply, hold finger over air cap,
and pull the trigger. This will force all the air through the
gun down the air check valve, blowing out any excess
paint that may have been trapped.
Cleaning the check valve and air hose is very important.
Any blockage here prevents pressurization. To help
prevent paint from entering hose, refrain from overfilling
the container or tipping the spray gun at extreme angles.
Warning: Paint cup is under continuous pressure,
even after air line has been disconnected. Do Not pull
trigger after spraying! Release pressure with the cup
locking lever immediately after use. Wear eye protection!

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.
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.

Remedy
1) Increase air pressure
2) Reduce pressure (pressure pot only)
3) Thin paint more
1) Be sure to maintain proper gun distance, 4" to 8".
Reduce material or use a smaller air cap. An air
hose that is too long will reduce atomizing air.
2) Keep object being sprayed out of direct sunlight.
When spraying in warmer temperatures use a
slower evaporating solvent or a retarder.
3) Try to keep material and object being sprayed as
close to room temperature as possible. When
sprayed on a cold surface most paints will
become too thick to flow out properly.
1) Store material off concrete floors at room temperature.
2) Apply lighter coats and allow for proper dry time.
3) Use a slower evaporating solvent or retarder.
4) Do not spray in windy conditions.
Clean all parts with a cleaning solvent. Use one
solvent rag and a clean wiping rag. Change rags as
required. If problem persists use a fish eye eliminator.
1) Move gun faster or decrease material flow.
2) Maintain proper gun distance.
3) Reduce amount of thinner or use a faster drying

Accessories:
Venturi

venturi gun for
running off a
compressor.
(When used with a 1
quart suction pot, a
position 49 check
valve is required)

Shut off valve
accessory for the
turbine gun to
shut off air with

(includes hose
assembly for
pressurizing the
suction pot)
Tool kit
for packing adjustment, nozzle
removal, and cleaning.
Technical hints:
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.

2-1/4 GALLON PRESSURE POT PARTS LIST & DIAGRAM
Jan02
Shown with
agitator option.
Warning: Never allow
pressure in pot to
exceed 50 lbs.
31
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.
