SAFETY PRECAUTIONS

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.

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

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:

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.

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.

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.

SPECIFICATIONS - PRESSURE POTS

Figure 1. - Typical 2 quart system

WARNING: Make sure nuts

and bolts are properly tightened

before pressurizing the pot!

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.

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.

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.

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.

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%)

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.

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.

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

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).

 Round jet (A-711 only) Horizontal Fan Vertical Fan

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.

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.

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.

CLEANING INSTRUCTIONS - PRESSURE POTS

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.

Warning for A-711 gun only: 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!

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.

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.

OPERATING INSTRUCTIONS

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.

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 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 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.

Warning!

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.

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

MAINTENANCE - A-711 HVLP GUN

MAINTENANCE - PRESSURE POT

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.

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.

DISASSEMBLY:

1. Remove air cap, detent plate, spring; spring cap,

spring, & needle. Lastly remove nozzle using nozzle

tool.

ASSEMBLY:

2. Lubricate needle with vaseline. Install needle, spring,

and spring cap (loosely).

3. Adjust packings by turning the packing wrench clockwise and triggering the needle while you tighten. When

the needle binds, back off until the needle just moves

freely.

4. Install nozzle, spring, detent plate, and air cap.

5. Check trigger free travel. Important: Ensure that the

fluid adjusting screw is backed out all the way.

If adjustment is required continue to step 6.

Turbine gun.....1/16" spring travel (before needle moves)

Venturi gun.....3/8" spring travel (before needle moves)

6. Adjust trigger by removing the spring cap, loosening

the lock nut and turning the drum until correct free

travel is achieved. Tighten lock nut and install spring

with cap.

If tool kit is required, use order #L080-650 for 1 x

packing wrench, 1 x nozzle tool, and 1 x cleaning brush.

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.

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

Accessories:

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.

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.
