LEMMER TURBINE TECHNICAL FEATURES:
• Turbine life is almost solely dependant on air quality.
Any dust in the intake air will wear the turbine. The
Lemmer T-series all use a unique large area fine filter for
trouble-free service!
• The Lemmer T-55 turbine is a 2 stage, small diameter,
low rpm, and low operating temperature. The T-75 turbine
is a 3 stage, small diameter, higher rpm with variable
motor speed. The T-90Q is a 4 stage turbine with several
fixed speeds and patent pending motor control
technology to minimize heat and noise.

SPRAY GUN CONTROLS
Figure 1a - Gun controls, A700 series.
Figure 1b. - Gun controls, A728 non-bleeder
Material Volume Control Knob
Controls how far the trigger can be pulled back. Turn out
for more material flow, turn in for less.
Air flow control valve.
Air Control Valve (on end of Turbine hose)
Controls both atomizing air and pressure in the one quart
cup. Control overspray mist by using only as much air as
is necessary for the material being sprayed. The lighter
the material, the less air needed. For T75Q and T-90Q
machines, select a motor speed first, then use the air flow
control valve to “fine tune” the spray if needed.
PREPARE FOR OPERATION
Figure 3. - Spray pattern control (turn air cap).
Spray pattern shape is determined by the 3 different
positions of the aircap on A700 guns. The aircap can be
rotated to make the pattern vertical, horizontal or in-
between on the A-728.
NOTE: The aircap adjusting ring on A-700 does NOT
have to be loosened to change patterns unless the air
cap is set to its widest pattern. Slight loosening may be
required to turn aircap on A-728.
Adjusting Spray Fan Width, A-700 Series.
Figure 4. - Spray fan width control (turn ring).
Spray fan size is determined by turning the control ring in
(for wide) or out (for narrow) for A700 series guns.
Adjusting Spray Fan Width, A-728
Use the fan control knob at rear of gun to adjust spray
pattern width. Turn the knob clockwise to decrease the
fan size, counter clockwise to increase it.
Note-all models: Smoother finishes can be obtained by
using a narrow pattern. More material output can be
gained by using a wide pattern.

PREPARE FOR OPERATION
PAINT STRAINING AND THINNING
The surface to be sprayed should be completely clean
and dry to achieve proper adhesion.
Always strain all material to be sprayed. This includes
color, reducer and hardners if used.
Figure 8. - Automotive paint reduction.
Paint Reduction - Automotive Type Finishes. Reduce
and catalyze all paint to manufacturer’s specifications.
Remember: To compensate for the faster drying time of
turbine systems, use a reducer one step slower than for
conventionalair spray to enhance flow-out.
Figure 9. - Industrial paint reduction.
Paint Reduction- Industrial or domestic coatings (if
no reductions are given.) Thoroughly mix material to be
sprayed, and gradually mix in the proper reducer until
proper spraying consistency is reached. To test: withdraw
stir stick from the thinned paint. As soon as the paint
stream running off the stir stick breaks into droplets, the
first few drops should be about one second apart.
Figure 10. - Test Spray Pattern.
Test Spray Pattern.
Spray material on a test surface to check for proper
material flow, coverage and atomization .
1. Open air valve to full flow.
2. Adjust aircap from neutral position to required pattern
size.
3. Adjust material control knob for proper flow.
Thin Materials: Decrease air flow through gun to mini-
mize mist.
Heavy Materials: If flow rate is too slow, additional
thinning will be needed or a larger fluid nozzle will be
required, see Page 8.
POWER SUPPLY, MOTOR CARE
All Lemmer Portable Turbine Systems are lifetime lubri-
cated. The only maintenance required is scheduled filter
cleaning and replacement.
FILTER MAINTENANCE
The filter must be clean at all times. This is very important
to the life of your turbine. We recommend that the filter be
checked weekly.
—Clean main filter by one of these methods—
Warning: Never put damp filters in the turbine!

Tap gently on flat surface dirty side down.
Figure 6. - Cleaning filter with air.
Direct compressed air (100 P.S.I. max.) thru panel oppo-
site the direction of arrows.
Figure 7. - Cleaning filter with water.
1. Soak 15 min, in water and a mild detergent.
2. Rinse until clean.
3. Air dry - do not use compressed air.

SELECTING THE PROPER FLUID SET
The Lemmer series 700 spray gun comes with the 1.4 mm nozzle set which is desired for most industrial finish applica-
tions. However, other combinations may be required for very fine finish work, or when spraying heavier materials.
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%)
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 and choose the nozzle which lists the viscosity range (under "type of material") your
material falls into.
Note: This 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.

For ordering details see parts list in back of manual. Note: nozzle and needle must be same size, eg: a 1.4 mm
needle will not work with a 2.0 nozzle. Aircaps and nozzle/needle sets must also be matched for correct operation.
VARIABLE SPEED CONTROL ON T-75Q AND T-90Q
VARIABLE SPEED CONTROL
The T-75Q and T-90Q are equipped with a variable
speed motor control which gives the user a wide range of
adjustment over atomization, heat and noise. An
additional, patent pending feature of the T-90Q will
automatically slow the motor when spraying stops to
reduce heat and increase motor life.
INITIAL SPEED SETTING
An excellent starting point is speed 2 on the T-75Q, or
speed 3 on the T-90Q. These speeds are typically used
with medium viscosity materials which are sprayed with
nozzles of 1.3 to 1.8 mm.
NOTE: When first selecting a motor speed, always
ensure the airflow control valve on the hose is fully open
to prevent interference between these two controls.
ADJUSTING THE SPEED
Thicker paints and/or nozzles larger than standard size
(1.4 & 1.5mm) often need more power for correct
atomization. For these situations, use a higher speed
setting.
For thinner paints, smaller nozzles and/or finer work,
excess air pressure may cause unwanted overspray. For
these situations use a lower speed. A lower speed setting
will also reduce air temperature from the turbine, which is
important if the material tends to dry very quickly.

SPRAY TIPS FOR TURBINE SPRAYING
Figure 15. - Proper way to trigger spray gun. Figure 16. - Result of flexing wrist while spraying.
Get professional looking results by following the spray
tips below.
1. Turn Turbine on a few minutes before spraying, to
allow air to warm up.
2. Adjust air control valve for the minimum air required
to atomize the fluid properly. (optional on the T-55).
3. 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. (See figure
16). This also saves material and reduces mist.
4. Move with a smooth arm stroke Move the gun at a
steady even pace while keeping the gun perpendicu-
lar to the surface. (See figure 15) Do not move the
gun by flexing your wrist. Fanning the gun will cause
excessive overspray and uneven coverage. (See
figure 16). If the rate of speed is not comfortable for
you, select another nozzle/needle size according to
charts on page 8.
5. 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: For a nice even finish, always overlap previ-
ous strokes by the same amount, generally 50%. Put
on a full wet coat whenever possible.
PROPER SPRAYING TECHNIQUES
Warning: Keep the Turbine away from the spray area.
Turbine filter must be clean to provide motor cooling
and atomizing air.
1. When using a turbine spray system, use slower
reducer or thinner to compensate for the faster drying
time due to the warm air of the turbine. DO NOT
OVER REDUCE. Hold the spray gun closer and a
slower drying reducer to enhance paint flow out.
2. To avoid runs and snags, remember this unit applies
more paint per pass than a conventional spray gun.
Take a minute to experiment on a discarded panel.
3. Be sure to turn turbine on a few minutes before
spraying for warm up time. Be sure to turn turbine off
when not in use, they do not shut off automatically.
4. When blending spots, work from the outside in. Start
one inch out, no dusting. This eliminates “chronic
halo” .
5. We recommend using two lengths of 25 foot hose
when applying automotive finish coats. The additional
hose will cool the air for better “flow out”.
6. Be sure to use the proper flluid nozzle, needle and
air cap for the material you are spraying, see page 8.
The use of a smaller aircap than fluid nozzle will
produce a smoother finish.
7. When material is first being applied, have the fluid
nozzle and aircap in the "normal spray pattern"
position as shown on previous page, then make
adjustments from there to control fan and atomiza-
tion.

CLEANING INSTRUCTIONS
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 refered to as "solvent" from
here on in.
1. 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 pressure tubes,
blowing out any excess paint that may have been
trapped.
Figure 17. - Back flushing gun.
2. Solvent flush gun. 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.
Clean needle, fluid nozzle and air cap with solvent
and brush.
Figure 18. - Solvent flushing gun.
3. Lube instructions. To keep the gun in proper work-
ing order be sure to check and lubricate each num-
bered item in diagram using silicone-free spray gun
lube or vaseline.
1. Lube the Trigger Axle
2. Lube the Needle - full length
3. Lube all threaded areas
4. Lube Trigger Pivot as needed
Figure 19. - Lubricating gun.
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 sub-
stance.
Note: Back flush-
ing is very impor-
tant in keeping
valve (1), hose (2),
and tube (3) clean.
Any blockage here
prevents pressuri-
zation. To help
prevent paint from
entering tube (3),
refrain from over-
filling the con-
tainer 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 spray-
ing! Release pressure with the
cup locking lever immediatly
after use. Wear eye protection!

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. Adjusting less than 3/8" decreases
trigger free play. 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.
DISASSEMBLY, A728:
1. Remove air cap ring and aircap. Next remove material
flow adjusting knob and spring from rear of gun, then
grasp needle and remove. Lastly remove nozzle using
nozzle tool or 13mm wrench.
ASSEMBLY, A728:
1. Lightly lubricate needle with vaseline and insert
through rear of gun. A728 needles require no
adjustment.

SPRAYING WITH A PRESSURE FEED SYSTEM
WARNING: NEVER AIM SPRAY GUN AT ANY PART
OF THE BODY. EVEN WHEN TURBINE IS OFF, THE
SPRAY GUN WILL RETAIN FLUID PRESSURE.
IMPORTANT: BEFORE TURNING ON AIR PRESSURE,
TURN OUT THE REGULATOR ADJUSTING KNOB ALL
THE WAY COUNTER CLOCKWISE TO SHUT OFF AIR
PRESSURE. TURN ON THE AIR AND THEN ADJUST
THE REGULATOR TO THE REQUIRED PRESSURE.
Pressure feed spraying operates basically the same
whether using the 2 quart remote, or the 2-1/2 gallon
paint tank. The main advantages of pressure feed are:
1. The spray gun can operate in any position, and fit in
smaller areas.
2. The weight of the material is off the spray gun for less
operator fatique.
3. A wider range of viscosities may be used with the
same fluid nozzle.
4. Generally can increase application rates and reduce
paint mist.
5. Saves time by requiring less fills.
OPERATION: Reduce material as recommended by
manufacturer, strain, and fill container no more than 3/4
full. Leave turbine turned off, and turn compressor on.
Turn regulator knob clockwise until two quart reads 2 to 4
P.S.I., on the 2-1/2 gallon tank to read 4 to 8 P.S.I.
(Heavier material or longer material hose length will
require more pressure.)
Pull trigger of spray gun fully, the material stream should
travel 12" to 18" in a downward arch. Increase or de-
crease the regulator pressure as necessary to obtain
proper material flow.
Turn turbine on and adjust the spray pattern with the
pattern control ring. It is best to control the gun speed
with the regulator by increasing or decreasing regulator
pressure rather than with the trigger.
BE CAREFUL NOT TO OVERPOWER THE ABILITY OF
THE GUN TO ATOMIZE PROPERLY BY USING TOO
MUCH FLUID PRESSURE.
WARNING: Never attempt to loosen or remove the cover
before fully releasing the air pressure. Turn air compres-
sor off, and pull lift ring on relief valve, or turn out pres-
sure release screw until pressure is completely released.
TROUBLE SHOOTING:
CONTAINER FAILS TO PRESSURIZE:
Be sure the bleeder hole on the underside of the paint
tank lid under the regulator is clean. On the two quart, be
sure the check valve underneath the lid below the regula-
tor is free and clean.
INTERMITTENT SPRAY PATTERN:
Check the gasket on the container for leaking.
CONTAINER PRESSURIZES BUT NO MATERIAL
FLOW:
Release pressure, check fluid nozzle for blockage.
Remove material hose and blow out with compressed air.
TWO QUART CUP
When spraying is finished, turn off both the compressor
and turbine. Release the pressure in the cup with the
pressure release screw. Elevate the spray gun and pull
the trigger, this will allow the material in the fluid hose to
drain back into the cup.
Flush out with the appropriate solvent using compressor
air only. Be sure to always release pressure on two quart
before unscrewing the lid. A light coat of vasoline on the
cup threads is recommended.
CAUTION: If the cup is accidentally tipped over or held
at too great an angle, fluid might leak into the regulator.
In the event this happens, clean immediately.

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 Lemmer outlet. 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 SPRAY GUN BE KEPT CLEAN
AND FREE OF RESIDUAL PAINT BUILD-UP ON THE INTERNAL PARTS. IT MUST BE CLEANED AFTER EVERY
USE.
Cause
The 710 Spray Gun requires pressure
in the paint cup to force the material
being sprayed up the fluid tube and
out the fluid nozzle. Any blockage
restricting free material flow, or loss of
air pressure in the cup, will greatly
effect gun performance.
Needle not seating in fluid nozzle.
Air passages blocked in air cap, fluid
nozzle partially plugged.
Remedy
1) Check fluid nozzle and fluid tube for dried
paint blocking passages, for tightness, being
bent or damaged. If blocked, clean with
brushes provided after soaking in solvent.
2) To check air pressure to cup, back flush
your gun. If air is not flowing freely from
lower air pressure tube, determine where
the blockage is and clean by soaking in
solvent and blowing out with air.
3) If air is flowing freely in step 2, check for
positive seal of cup gasket. Do this by
adding a couple of inches of solvent to cup,
tilt gun with air on, and rotate gun a full 360°
slowly. Any leaking at seal indicates a loss
of air pressure. Replace gasket.
4) Check needle packing adjustment. Any fluid
loss through packing will effect fluid pres-
sure, and will also cause a paint build up in
the gun body. The gun body may be soaked
in solvent and cleaned with the brushes
provided. When soaking gun body keep
air control valve out of the solvent.
5) Check needle drum adjustment. Material
flow will be restricted if there is too much
free travel between the trigger and the
needle. (A700 series)
NOTE: Be sure that the proper set has been
selected for the material being sprayed.
6) Ensure the check valve on gun is not
blocked and is installed correctly. i.e.
tapered end points to container(A-728 only)
Check needle drum adjustment. Check for
loose fluid nozzle, bent nozzle or needle
See needle packing adjustment. If packing is
set too tight, needle will not restore after
trigger is released. Replace if nozzle or
needle is worn.
NOTE: nozzle & needle must be the same size,
eg: a 1.4 mm needle will not work with a 2.0
mm nozzle.
Remove and soak in solvent. Do not use
metal probes to clean orifices as this will
permanently damage them.

Cause
The atomized paint droplets are not
flowing together to form a smooth,
level, uniform surface. This can be
caused by the following:
1) droplets too large
2) droplets drying too fast to flow out
3) cold weather spraying.
Condensation of moisture trapped in
the applied coating when spraying in
hot, humid conditions.
Silicone contamination from lubri-
cants, grease, polish of waxes on the
surface being sprayed.
Applying too much paint per pass for
the drying conditions.
Sprayed film surface drying before
solvent gas can be released.
Remedy
1) DROPLETS TOO LARGE - Be sure to
maintain proper gun distance, 4" to 8". See
air cap ad justment on. If droplets are still
too Iarge, reduce material or use a smaller
air cap. Be sure air intake filter on Turbine is
clean to allow full air flow. An air hose that is
too long will reduce atomizing air. Ensure
airflow contol valve fully open (all models) or
increase motor speed (T-75Q & T-90Q)
2) DROPLETS DRYING TOO FAST TO
FLOW OUT - Keep object being sprayed out
of direct sunlight. When spraying in warmer
temperatures use a slower evaporating
solvent or a retarder.
3) COLD WEATHER SPRAYING - 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) Allow turbine to warm up a few minutes
before spraying.
2) Store material off concrete floors at room
temperature.
3) Apply lighter coats and allow for proper dry
time.
4) Use a slower evaporating solvent or re-
tarder.
5) Do not spray in windy conditions.
Clean all parts with a cleaning sclvent. 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 thinner.
1) Apply material in lighter coats to allow
proper evaporation.
2) Be sure to use recommended thinners.
3) Follow steps above in "droplets too large” to
increase atomization.

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.
