WHAT’S DIFFERENT ABOUT AIRLESS SPRAYING?
Airless sprayers represent the newest advance in painting
technology for homeowners. Results are basically the
same as for compressor-type sprayers, but there are
important advantages for airless sprayers.
1) Lower Initial Cost
COATING APPLICATIONS
With no compressor, tank, pressure regulator, gasoline
engine or large electric motor, an airless is a much
simpler unit than compressor-type sprayers of similar
capacity.

2) Convenience
All you need is a can of paint and an extension cord.
3) Less Overspray
With airless sprayers, it’s easier to avoid overatomizing
the paint, resulting in less misting. Tighter spray pattern
means less overspray. You can more easily keep the
paint going where you want it to go - not into the air or
onto another surface.
4) Faster Painting
Since only paint is being pumped onto surfaces, airless
sprayers will generally paint much faster than compressor
units.

GENERAL DESCRIPTION
Spray Gun
The spray gun is designed specifically for airless spraying. Since there is high pressure, the spray tip and gun
valve are made of tungsten carbide for maximum wear
resistance.
of the diaphragm to draw in and force out the paint.
The paint block operates as follows: The piston in the
hydraulic pump forces hydraulic oil toward and away from
the diaphragm. This action moves the diaphragm up and
down, forcing paint through the spray gun at high pressure.
As a safety feature, the spray gun can be locked with the
trigger safety lever when you are not spraying. Be sure to
read all warnings concerning the high pressures of airless
spraying on pages 3 & 4.
Prime Valve
The prime valve knob is located on the front of the paint
block. When turned to “prime”, it circulates paint to vent
the air trapped in the paint block out to the hopper. It will
continue to recirculate the paint until the knob is manually
turned to the “spray” position.
Hydraulic Pump
The hydraulic pump is located at the front of the sprayer,
directly under the paint block. It operates as follows: The
electric motor is connected to an eccentric bearing inside
the hydraulic pump. The piston rests on the bearing. The
movement of the bearing causes the piston to move up
and down. When the trigger on the gun is pulled back,
this action moves the pump diaphragm. Diaphragm
movement forces the paint through the outlet valve and
on through the paint hose and spray gun. The paint goes
through the spray gun at high pressure, causing it to
break up (atomize) into fine particles. This gives a smooth
and even paint coating. Pressure and delivery rate are
regulated by the pressure control knob and the size of
spray tip.
When the prime knob is turned to “spray”, flow is shut off
through the return tube and is routed to the paint hose for
spraying.
The prime valve also serves to relieve pressure on the
system during shutdown and cleanup. The pressure is
relieved by turning the prime knob to “prime”.
The prime valve has another important function. It is a
safety relief valve. If too much pressure builds up in the
sprayer, the prime knob will dump this pressure harmlessly back into the hopper.
Diaphragm
CAUTION
The diaphragm is the heart of the sprayer. In addition to
pumping paint, it also serves as a gasket between the
hydraulic pump and paint block. As such, it prevents the
paint and hydraulic oil from mixing. The sprayer operates
at 1725 strokes per minute. This means that the diaphragm forces a “gulp” of paint out the spray gun 1725
times every minute.
Change the position of the priming knob slowly. This
will prevent breaking any valve parts. Always reduce
the pressure with the pressure control valve before
turning the priming valve knob.
Inlet Valve
The inlet valve is located on the top of the paint block at
the front of the sprayer. The paint hopper screws hand
tight onto this valve. The valve operates automatically to
control the flow of paint from the hopper into the paint
block. It does this by opening up when the piston and
diaphragm are on the downstroke, allowing a “gulp” of
paint to enter the paint block. The inlet valve then closes
when the piston and diaphragm are on the upstroke. This
closing prevents paint from going back through the inlet
valve into the paint container. (Inlet valve acts as a check
valve.)
An insert fits in the inlet hole on the bottom side of the
paint block. This insert reduces wear by protecting the
diaphragm from the metal edges of the inlet hole.
The diaphragm is made of flexible, tough plastic. It is not
harmed by common solvents.
Pressure Control Valve
The manually operated pressure control knob is on the
front of the hydraulic pump. When the knob is turned
clockwise, oil pressure is increased. When the knob is
turned counterclockwise, oil pressure is reduced. The
pressure control knob regulates the pressure on the
diaphragm up to 2800 PSI.
Outlet Valve
The outlet valve is also located on the top of the paint
block at the front of the sprayer. It operates automatically,
serving as a check valve. When the priming valve is on
“S” (Spray) position, the outlet valve directs the flow of
paint out into the spray hose and through to the spray
gun. When the diaphragm and piston act to “gulp” more
paint, the outlet valve closes. The closed valve prevents
(checks) paint in the spray hose and spray gun from
returning to the paint block.
Always reduce the pressure (turn knob all the way counterclockwise) when cleaning system, or when switching
the position of the prime knob.
Paint Block
The paint block is located on top of the hydraulic pump
and diaphragm and is fastened with four socket-head
bolts. The paint block is simply a valve block with inlet,
outlet, and prime valves. These valves regulate the flow
of the paint through the block during priming and spraying. The inlet and outlet valves work on opposing strokes
The inlet and outlet valves work in harmony with the
diaphragm and piston to provide a constant flow of high
pressure paint to the gun.

PREPARE FOR OPERATION
CONTROLS
CAUTION
1) On-Off Switch is located on the side of the electric
motor.
CHANGE THE POSITION OF THE PRIMING KNOB
SLOWLY. THIS WILL PREVENT BREAKING ANY
VALVE PARTS. ALWAYS REDUCE THE PRESSURE
WITH THE PRESSURE CONTROL KNOB BEFORE
TURNING THE PRIMING KNOB.
2) Pressure Control Knob is manually operated and
located on the front of the hydraulic pump. When the
knob is turned clockwise, hydraulic pressure is
directed toward the diaphragm. When the knob is
turned counterclockwise, hydraulic pressure is reduced. The pressure control knob regulates the
pressure on the diaphragm from 0 PSI when turned
fully counterclockwise to 2800 PSI when turned fully
clockwise.
POWER SUPPLY, MOTOR CARE
The motor is located at the rear of the sprayer and is
connected to the hydraulic pump. It is furnished with a 3wire electric cord. The third wire (ground) should never
be cut off. Any extension cords used must also be 3-wire,
14 gauge minimum with a 3-wire plug that will plug into a
3-wire grounded electrical outlet. Do not use 2-wire
extension cords. The maximum length of all cords and
extension cords used should not exceed 100 feet. If you
need to spray farther away from a power source, use
more paint hose, not more extension cords. Shorter
extension cords will assure maximum electrical power for
proper operation. Cords and extension cords should be
protected from vehicle traffic and sharp cutting edges or
objects. Any worn or damaged cords should be replaced
promptly.
Always reduce the pressure (turn knob all the way out
- counterclockwise) when cleaning or switching the
position of the priming knob.
3) Priming Knob is located on the front of the paint
block. It is manually turned to the “P” or “S” position.
When on “P” (prime) it serves to rid the sprayer of air
by directing the initial air volume of the inlet valve
back into the paint hopper. It will continue to do this
until paint comes through and it is manually switched
to the “S” (spray) position.
The priming valve also serves to relieve pressure on
the system during shutdown and cleanup. The
pressure is relieved by turning the priming knob to
“P”.
The motor should always be kept clean and dry. Paint
acts as an insulator. Therefore, too much paint on the
motor will cause it to overheat.
When the priming knob is turned to “P” (prime), paint
is drawn from the hopper into the paint block. The
paint block then routes the paint through the return
tube back to the hopper. This primes the paint
system. When the priming knob is turned to “S”
(spray), flow is shut off through the return tube and
you can spray.
Electric service must be 115 VAC, 60 Hz, 15 Amp minimum circuit.
PAINT STRAINING AND THINNING
When a container of paint is exposed to the air for a
period of time, a “skin” may form on top. This “skin”
should be removed. If necessary, the paint should be
strained through a strainer.
NOTE: Newer L-1000 models use symbols instead of
“P” or “S” position as shown below.
Under normal conditions, paints used with this airless
sprayer do not have to be thinned. However, there is a
possibility that you may use paint that is too thick to be
sprayed. In this case you will have to thin the paint. As a
general rule all paints need about 5% thinning, whereas
light materials such as linseed oil, and clear lacquers do
not require any thinning.

When thinning paint to spraying consistency (viscosity),
use appropriate thinner - water for latex paint, mineral
spirits for oil base paints (or consult the instructions on
the paint can for proper thinner).
SELECTING CORRECT TIP SIZE
OIL FILLER
PLUG
The spray tip provided with your new system is an average size for general painting. After a few jobs, you may
want to select a tip more suited to your liking. Tips must
be the correct size for proper atomization, and to provide
the operator with the right speed. The chart on page 11
will give you a general idea on how to choose the right tip.
If you need some more help on choosing tips, please ask
one of our trained personnel in any Lemmer location.

OPERATION
START UP PROCEDURE
ADJUSTING SPRAYING PRESSURE
1) Check oil level as described on page 15.
The ideal way of spraying is to have a perfect spray
pattern with the lowest possible pressure to keep overspray to a minimum. These example spray patterns show
the effect of pressure and tip size.
2) Check for suction. Before putting the paint hopper
on, check for suction at the inlet valve. To do this,
turn the priming knob to “P” (prime) position and start
the sprayer with pressure control knob counterclockwise (minimum pressure). Place the palm of your
hand over the inlet valve and slowly turn the pressure
control knob clockwise until suction is felt. Turn
pressure control back to minimum and re-install
hopper. (If no suction was felt, free the inlet valve as
described on page 17. If this does not help check
“Bleeding Hydraulics” on page 16.
Tip is too small or paint is too thick.
3) Be sure all fittings are tight, and make sure gun
trigger is in safety lock position.
4) Prime pump with thinners. Pour a small amount of
thinners (which is compatible with paint about to be
sprayed) into the hopper. Turn pressure up until it is
circulating through the return tube. Turn pressure
back to minimum and discard the thinners. Now you
are ensured that paint will pump through with no
possibility of gelling due to incompatibility.
Pressure is too low or tip is too large.
(some "tailing" is normal)
Correct pressure and tip adjustment (some tailing is normal).
5) Prime pump with paint. Pour paint into hopper (after
it has been prepared). With priming knob in prime
position, turn pressure up and let the paint circulate
through the return tube for about 2-3 minutes. This
will ensure all air is bled out of the paint block.
Figure 4. - Spray pattern examples.
IF TIP BECOMES CLOGGED
6) Switch to spray. Turn pressure back to minimum
and switch priming knob to spray.
1) Rotate the tip to the “Clean” position.
7) Build up pressure. Slowly turn the pressure up while
watching for leaks at connections.
2) Pull trigger and spray. This should clear the tip of any
blockage.
8) You are now ready to spray! Disengage safety lever
on the gun. Remember this is high pressure-never
point the gun at anyone. Pull the trigger and spray
out the air or thinners in the system until the paint
reaches the tip.
3) Rotate the tip back to the “Spray” position and continue spraying.
4) If the clogging continues, clean or replace the gun
filter and see the “Getting Started” section of this
manual for instructions on straining and thinning
paint.
SHUT DOWN PROCEDURE
Always reduce pressure, slowly turn prime knob to prime,
trigger gun to release pressure build up in hose, and turn
motor off. Never leave any pressure in the system
when not in operation.

Measure the paint’s viscosity as follows: (note, paints that
are intended to be rolled should be thinned for air or airless
spraying. A general rule of thumb is 5 to 15% for latex and
oils, 30% or more for fine finishes. (consult your paint
supplier for best results).
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.

Tip chart example: Latex
stain is being sprayed onto
a fence. The paint is fairly
thick (like a very heavy
motor oil) and the L-1500
is the spray machine. The
maximum tip is a .015 for
an L-1500. Draw a line
along the .015 tips as
shown below. Everything
above the line is sprayable
with the L-1500. Now just
choose the fan width. For
fences a 6” width will give
a lot of control, so the
intersecting best choice
would be a 3-15 tip with a
yellow gun filter.

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

HINTS FOR AIRLESS SPRAYING
••You can learn to spray paint as easily as you can
learn to paint with a brush and roller. Get professional looking results by following the spray tips
below.
WARNING
DO NOT BEGIN SPRAYING BEFORE READING THIS
SECTION AND ALL PREVIOUS SAFETY INFORMATION.
1. KEEP THE GUN PERPENDICULAR TO THE SURFACE
Figure 9. - Right and wrong way to hold spray gun.
Always hold the gun perpendicular to the surface with
the tip approximately 12" from the surface. If held at
an angle (up and down or side to side) paint will build
up unevenly and leave the work splotchy. (See figure 9).
2. MOVE WITH A SMOOTH ARM STROKE
Move the gun at a steady even pace while keeping
the gun perpendicular to the surface. (See figure 10)
Do not move the gun by flexing your wrist. Fanning
the gun will cause excessive overspray and uneven
coverage. (See figure 11). If the rate of speed is not
comfortable for you;
a) To slow down, either lower the pressure, or use a
smaller spray tip.
b) To speed up, either increase the pressure, or use
a larger tip. (A larger volume pump is required if you
want to exceed the L-1000's maximum .017 limit).
Figure 10. - Proper way to trigger spray gun.
3. START MOVING THE GUN BEFORE TRIGGERING
To get smooth overlap and prevent initial paint
buildup, start your stroke movement before pulling the
trigger. At the end of the stroke release the trigger
before stopping.
NOTE: To assure uniform paint coverage, overlap
each stroke by 40% - 50%.
4. INTERMITTENT USE
If you are spraying and decide to stop for several
minutes, lock the spray gun trigger and submerge the
tip in a container of the appropriate solvent. This will
prevent paint from hardening in the tiny spray opening and clogging the tip. Be sure to release the
pressure by turning the prime knob to prime and
switching the pump off.
Figure 11. - Result of flexing wrist while spraying.

CLEANING INSTRUCTIONS
2. REMOVE AND CLEAN SPRAY TIP. With trigger lock
engaged, and unit turned off, remove spray tip, filter
and washer from gun and place parts in a container
of suitable solvent.
AS WITH ANY SPRAY EQUIPMENT, YOUR SPRAYER
MUST BE CLEANED PROPERLY OR IT WILL NOT
OPERATE PROPERLY. CLOGGED VALVES AND
FILTERS ARE THE MOST COMMON CAUSES OF
PROBLEMS. IF FOLLOWED, THESE GUIDELINES
WILL INSURE TROUBLE FREE PERFORMANCE
FROM YOUR SPRAYER.
3. PUMP PAINT OUT OF HOSE. Pour suitable cleaning
solvent into the hopper and prime the pump. Clean
the hopper with a brush or rag. Lower pressure and
turn prime knob to “spray”. Disengage trigger lock
and trigger gun into the paint can until thinner appears. It is best to submerge the nozzle in the paint or
thinner to prevent splashing.
WARNING
DO NOT CLEAN THE SPRAY GUN OR TIP ASSEMBLY
UNLESS THE PRESSURE HAS BEEN RELEASED
FROM THE SYSTEM. SEE PAGE 3 & 4 FOR FURTHER
PRECAUTIONS.
Caution: Conductive , metal containers must be used when
flushing flammable fluids
through the system. A metal part
of the spray gun should be held
firmly against the grounded metal
pail when relieving the pressure from the gun.
CAUTION
CLEAN WITH WATER IF LATEX IS USED. CLEAN
4. FLUSH HOSE AND PUMP. Continue pumping
suitable solvent through the pump, hose, and gun into
an empty container until it runs clear. Pump further
until all fluid is out of the system. Rinse and wipe
clean any paint on the exterior.
WITH MINERAL SPIRITS FOR OIL BASED PAINTS.
NOTE
5. CLEAN FILTERS. Remove the hopper screen and
gun filter, and rinse both clean. Use an old toothbrush
to remove any sediment.
We recommend running light oil or mineral spirits through
the unit before storing. When using latex paints, make
sure the unit has been completely cleaned before storing
with mineral spirits. Mineral spirits react with latex paint to
form a jelly-like substance which can damage your pump.
Figure
6. LUBRICATE VALVES. (If an oily solvent was used in
cleaning, ignore this step and move on to #7 storage.
If a strong solvent such as lacquer thinner was used,
lubricate the valves only). Before storing for an
extended period of time, drain all the water out of the
hose, gun, and pump. Tungsten carbide parts in the
valves will corrode if left in water for long periods of
time. With the pump running in the prime mode, place
a few drops of light oil into the inlet valve. Let the
pump run until it spits oil drops out the return fittings.
This will displace any remaining water and lubricate
the valves for storage. With the motor off, remove the
gun and place some oil into the gun. Trigger the gun
until oil seeps out the ball and seat. A few drops of oil
on the tip/packing assembly is also recommended.
See Figure 12.
7. STORAGE. The paint hose should be drained, coiled,
and tied. When rolling up, be cautious not to twist or
kink the hose. Roll diameter should be about 2 feet. It
is best to hang the coiled hose on a bracket or large
nail out of the way to keep it from being damaged.
The pump and gun should be stored on a shelf out of
the way. (Make sure that the gun safety lever is
engaged). They should be kept in a cool, but not cold,
dry place and clear of traffic to avoid accidental
damage. The electric cord should be wound on itself
and tied.
12. - Oil valves before storing.
1. PUMP OUT REMAINING PAINT. Flex the return
tube out of the hopper and hold it above a paint
container. Turn prime knob to prime position, turn
motor on, and increase the pressure until it is pumped
dry. Move the return tube back into the hopper.

MAINTENANCE & SERVICE
WARNING
Testing diaphragm:
TURN POWER OFF AND RELEASE ALL PRESSURE
FROM THE UNIT BEFORE DOING MAINTENANCE.
1. Remove inlet valve.
2. Turn motor on briefly and using the blunt end of a pen
or pencil, feel if the diaphragm is moving.
Paint hose:
3. If it is not moving, check oil level. If oil level is OK.,
bleed the air from the hydraulics. If hydraulics are
OK., change the oil. If paint is mixed in with the oil,
the diaphragm is ruptured and requires replacement
and the internal hydraulic system requires cleaning
as detailed in next paragraphs.
Periodically inspect the paint hose. If the hose is kinked,
cut, or worn, it must be replaced . It cannot be repaired. A
hose bursting at 2800 psi can cause significant damage
to property AND cause a serious injury if the spray injects
the skin. Replace with a grounded or conductive airless
paint hose that is rated for at least 2800 psi “working”
pressure.
Diaphragm replacement:
1. Remove the paint block assembly. Remove diaphragm assembly. With the unit lying on its back,
remove the hydraulic pump front cover. Drain the oil.
Spray gun
The filter should be cleaned or replaced after each use to
minimize tip clogging problems. If the gun valve becomes
worn and begins to leak, it should be replaced.
2. If paint has contaminated the oil reservoir, it must be
cleaned and the oil replaced. (Note: if strong thinners
or strong paints are found in the hydraulics, check the
oil seal for swelling and check the motor inside for
damage due to varnish softening). All internal parts
must be cleaned, i.e. bearing, hydraulic piston,
pressure vessel, pressure regulator, return tubes, and
oil elbow. Improper cleaning of these internal components may cause rapid hydraulic pump wear and may
cause eventual replacement. Replace the oil suction
tube with a new one. The pressure regulator
should be disassembled and properly cleaned,
the pump's pressure will then require resetting by
trained personnel and the use of an accurate
pressure gauge. Clean and dry paint block assembly
and housing ring pressure grooves. Reassemble with
a new diaphragm in reverse sequence. (See below
for proper torque sequence and proper oil refill level)
Diaphragm:
After finishing your first job with the sprayer, wait until
it has completely cooled down. Then tighten the 4 paint
block bolts with a 6mm allen wrench. The bolt are located on the top of the paint block as shown in figure 13.
Tighten opposite bolts in turn as shown. If you use a
torque wrench, tighten to 25 ft./lbs. (300 in./lbs.) torque.
Thereafter, tighten the paint block bolts every 3-4 operations. One lockwasher should always be used with each
of the 4 paint block bolts.
Proper torque on the paint block bolts assures efficient
operation of the diaphragm and prevents hydraulic oil
from leaking out between the paint block and hydraulic
pump. Do not over-torque or under-torque!
3. Tighten paint block assembly to 23 ft/lb torque using
a progressive ‘X’ pattern. See figure 13.
4. Bleed the pump. See page 16.
Tighten
Checking hydraulic oil level:
6 mm allen
wrench
Paint block
Check the hydraulic oil level before each use and after
every 20 run hours. The sprayer was shipped with the
proper amount of hydraulic oil in the reservoir, (hydraulic
pump). However, the oil should be checked before
starting. Check the oil by standing the sprayer up so that
it rests on the rear of the motor. In this position the
hydraulic housing will be up. Remove the oil filler plug on
the hydraulic housing face plate. Stick a sharpened
pencil or other long, thin object down the hole. The oil
level should be approximately 1/2" from the tip of the face
plate. Oil capacity is approximately 19 ounces. Use only
Nuto H 32 hydraulic oil (order number L034-120).

MAINTENANCE & SERVICE
Changing hydraulic oil
Prime valve
Change the hydraulic oil after the first 20 run hours and
every 50 hours thereafter. To change hydraulic oil,
proceed as follows:
If the prime valve is not properly cleaned after each use,
It may stick open. If this occurs, paint will flow through the
return hose when the valve is turned to “spray”. Working
pressure will then slowly begin to drop as the valve
wears. A new valve should be installed with new washers
and torqued to 100 in-lbs.
1) Remove the oil filler plug from the hydraulic housing
face plate.
2) Drain out the old hydraulic oil.
3) Clean the sprayer by running it with a filling of about
2/3 pint of cleaning fluid in the hydraulic housing.
Run it for only a few seconds. Do not use any cleaning fluid that is not compatible with rubber. (Varsol is
an excellent cleaning fluid)

4) Drain off cleaning fluid and allow sprayer to dry out as
best as possible.

Figure 14. - Prime valve parts.
5) Fill hydraulic housing with approximately 19 ounces
of hydraulic oil. Use only hydraulic oil order number
L034-120. (1 litre)
Replacing prime valve o-ring.
6) Since air may enter the system when the oil is
changed, the sprayer may have to be vented (bled).
To bleed out the air, see page 16.
1) Switch prime valve to spray position.
2) Carefully punch out pin (1), from the end which is
slightly smaller. (Newer models use 2 set screws.)
You will also have to bleed the air out of the system if you
remove the paint block or go into the hydraulic housing,
or if the sprayer loses prime due to rough handling.
3) Pull off knob. (2)
4) Unscrew cam (3) with a pair of long needle nose
pliers using holes provided. Newer models have a
two piece cam as shown in the parts diagram on
page 22.
Bleeding air from hydraulics
You will have to follow this bleeding procedure when you
change hydraulic oil, if you remove the paint block, or go
into the hydraulic housing, or if the sprayer loses prime
due to rough handling.
5) Remove star washer. (4)
6) Pull shaft (6) and spring (5) straight out.
7) If replacing the entire valve, remove seat (8) and seat
seal (9). Newer models do not use a seat seal.
1) Turn pressure control knob all the way counterclockwise, turn priming knob to “P”, and let sprayer run a
few minutes. It is sometimes helpful to turn ON-OFF
switch ON and OFF to assist in bleeding.
8) Clean all parts and install new O-Ring (7). See page
22 & 23 for order numbers of the two types of o-rings.
9) Grease o-ring, install shaft and spring.
2) Now turn pressure control knob clockwise to prime
the pump. If sprayer is warm from use, loosen oil fill
plug. When sprayer is primed, suction can be felt
with the palm of your hand. This may take 2-3
minutes. If sprayer does not prime, turn pressure
control knob counterclockwise and repeat the procedure.
10) Insert washer into cam, carefully thread on, and
tighten.
11) Line up hole in shaft with cam dip. (On set screw
type, fully bottom, pull back slightly to give about
1mm play, then tighten screw. Ignore following step.
12) Slide knob on and into spray position, make sure
holes line up, and press pin in. (Narrow end first)
Note: Diagram 18 shown in prime position.
Pressure control valve
The pressure control valve is preset at the factory for your
safety and is not adjustable except by a Lemmer service
centre. However, the valve is easily replaced on the job. If
the pump cannot pressurize to 2800 +/- 250 psi when the
gun is not triggered and there are no leaks or flow
through the prime valve, a new pressure valve cartridge
should be installed with a new washer and torqued to
approximately 50 in-lbs. The pump should be bled after
installation. See below.
16
MAINTENANCE & SERVICE
Inlet and Outlet Valves, General:
The inlet and outlet valves will wear. The rate of wear
depends on the type and quality of paint you use. As the
spraying pressure and vacuum drop, the outlet valve and
inlet valve should be replaced. However, first be sure that
the tip is not worn; this can cause a drop in spraying
pressure as well. New valves should be installed with new
washers and torqued properly.
Freeing stuck inlet valve
When little or no suction is felt, follow this procedure:
1) Fill inlet valve with thinners which is compatible with
paint being used.
2) Turn pressure control knob to maximum and priming
knob to prime. Start motor.
3) Carefully push the inlet valve nut up and down repeatedly with a screwdriver as shown in figure 15.
4) Check suction with the palm of your hand. Note: The
suction felt after thinners has gone through will not be
as great as if oil had just been pumped through.

Testing inlet valve (motor off)
1) Remove inlet valve (see “cleaning inlet valve”).
2) Clean thoroughly.
PAINT
BLOCK
3) Dry completely and stand upright on dry paper. Fill
with thinners.
4) If thinners empties quickly replace inlet valve.
5) If thinners leaks slowly, proceed to “testing inlet valve
(motor on)”.
SEALING
WASHER
Testing inlet valve (motor on)
Figure 15. - Freeing stuck inlet valve.
1) Build pressure up to maximum (with thinners).
2) Turn motor off. Do not bleed pressure or adjust
pressure control knob.
3) Turn motor on for 2 seconds and turn off immediately.
If motor buzzed and did not start, inlet valve (and
hydraulic piston) are functioning properly. If motor
started, replace the inlet valve.
CAUTION:
WHEN REMOVING OR REPLACING THE INLET
VALVE, PAY CAREFUL ATTENTION TO THE SEALING WASHER (SEE FIGURE 15). THE WASHER MAY
REMAIN IN THE PAINT BLOCK WHEN THE INLET
VALVE IS REMOVED. WHEN A NEW VALVE IS INSTALLED ONLY ONE SEALING WASHER SHOULD
BE USED. DIAPHRAGM FAILURE COULD RESULT IF
TWO WASHERS ARE USED.
4) If, with a new inlet valve the motor starts, return the
machine to your nearest Lemmer Service Centre for
service.
Cleaning or replacing inlet valve
1) Turn motor off.
2) Remove valve with a 27mm socket or an adjustable
wrench.
3) Thoroughly clean and inspect for foreign particles.
Note: Do not use hard objects to pry at valve.
4) Grease the threads and re-install. Do not torque inlet
valve to more than 40-50 ft./lbs.
5) If this does not solve the problem, check “cleaning
outlet valve”.
17
MAINTENANCE & SERVICE (CONTINUED)
Cleaning outlet valve
1) Remove outlet valve end cap with a 19mm socket or
an adjustable wrench. (See figure 16)
2) Remove cap seal, spring, and ball. If ball is stuck, tip
the machine and use a small screwdriver to “pluck” it
out.
3) Clean all parts including the outlet valve seat still in
the machine. Check the spring for wear and replace
if necessary. Note: Spring tension is critical, only use
original parts.
4) Grease the cap threads and spring. Drop the ball into
the seat, place cap seal and spring onto the cap and
tighten down. Caution - Do not tighten more than
18 ft./lbs.

• Follow shut down procedure before
servicing or cleaning equipment. (see
#1 overleaf)
• This instruction sheet is only a
supplement to your system operating
instructions. Read your system manual
before operating any high pressure
equipment.
• Remove filter for cleaning, then
reinstall and hand tighten the handle.
• To clean gun: flush the inside by spraying proper solvent, and wipe the exterior. (It is not
neccessary to disassemble gun components under normal circumstances).
• Injection hazard: Airless Painting Equipment can cause serious injury if the spray
penetrates the skin. Do not point the gun at anyone or any part of the body. The tip guard
provides some protection against accidental injection injuries, but is mostly a warning device.
Never put your hand, fingers or body over the spray tip. Gloves and clothing do not
necessarily offer any protection either. Keep the gun trigger safety lever in locked postion
when not spraying. Always have the tip guard in place while spraying.
In case of penetration seek medical aid immediately! Note to physician: Injection
into skin is a serious traumatic injury. It is important to treat the injury surgically as
soon as possible. Do not delay treatment to research toxicity. Toxicity is a concern
with some exotic coatings injected into the bloodstream. Consultation with a plastic
surgeon or reconstructive hand surgeon may be advisable. Be prepared to tell the
doctor what fluid was injected.
• 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)

• Caution: When a flammable liquid is sprayed there may be danger of fire or explosion
especially in a closed area.
• Use extreme caution when cleaning spray tip guard. DO NOT try to wipe off build up
around the spray tip before following shut down procedure. Follow the Shut down Procedure,
then follow the spray tip manufacturer’s instructions for removing and cleaning the spray tip.
• Never attempt to change spray tip or leave the unit unattended without first shutting off
pump, releasing fluid pressure, and locking the trigger safety lock.
• 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.
• Trigger guard helps reduce the risk of accidentally triggering the gun if dropped or bumped.
Do not use a spray gun without a trigger guard.

L-45 PARTS SERVICING
11) Lightly grease the packing (pos. 11) and exterior
threads of the ball spring assembly. Push firmly into
gun body and tighten 7-10 ft. lbs.
Use diagram on page 20 for reference.
Tools needed
10 mm socket and driver
2 x 8" or larger crescent wrench
12) Examine the trigger pins for wear and equal length.
Lightly grease and install.
1 x P/N L032-599 repair kit
Cleaning brush and lacquer thinner
13) Install retainer cap on rear of gun and install locking
nut. Tighten locking nut until approximately two
threads show out rear of the nut.
1) Initiate shut down procedure: Ensure unit is turned
OFF, prime valve is OPEN and all system pressure is relieved. Disconnect electric plug from
wall socket. See pages 3 & 4.
14) Thread gun handle into gun body.
15) Lightly grease threads of seat. Install trigger guard
over open end of seat. Hold gun trigger in open
position and install seat. Tighten to 30-40 ft. lbs. and
release trigger.
2) Using the two crescent wrenches, disconnect the gun
and gun handle from spray hose.
3) Remove spray tip or attachment assembly from gun.
16) The retainer cap should have a bit of slack in it and
should not be bottomed against the gun tightly. The
trigger should have 3/8" slack at the bottom of the
trigger before engaging against the trigger pins.
4) Hold gun trigger open and remove seat (pos. 4) from
gun. Release trigger. Never remove or attach seat
unless trigger is held in the open position. Permanent and expensive damage to both ball and
seat will result!
This slack is very important to the correct operation of
your gun. The gun and safety lock will not work
correctly if this step is not performed correctly.
5) Using 10mm socket and driver, remove adjusting nut
(pos. 17) from rear of gun.
To increase slack, loosen the locknut a little and test
slack again.
6) Grasp retainer cap (pos. 16) and pull away from rear
of gun. Remove the two trigger pins (pos. 8) from
gun.
To decrease slack, tighten the locknut a little and
test slack again.
7) The ball spring assembly can be removed from the
rear of the gun body by unthreading six to eight turns
and then pulling firmly towards rear of gun body
(position 25 & 7).
With too much slack, the gun may not turn on, but the
safety lock will work fine. With too little or no slack,
the gun may be permanently ON and the safety lock
does nothing.
8) Remove gun handle from gun and remove filter and
filter spring.
DO NOT RUSH OR IGNORE THIS STEP, CORRECT OPERATION OF THE SAFETY REQUIRES
PROPER ADJUSTMENT OF TRIGGER SLACK.
9) Clean all parts thoroughly and lay out on clean rag for
inspection.
17) Install tip attachment onto gun. Remove gun handle,
install spring and filter, lightly grease threads and reinstall.
10) If the ball (pos. 9) has a groove worn in it, the ball
spring assembly will have to be replaced. Usually the
seat will have to be replaced as well, as it wears
against the ball. Both of these parts are included in
the repair kit.
18) Place trigger in LOCK position. Install gun to hose,
tightening securely. Gun is now ready for testing and
use.

ELECTROSTATIC UNITS
The electrostatic WRAP-A-ROUND charge makes this
the best method of spraying metal with next to no overspray. It is best suited for industrial paints with an aromatic thinner base, i.e: toluol, xylol. The conversion kit will
hook up to most airless pumps and we carry a completely
self contained portable system.
ELECTRIC CUP GUNS
Hand held airless sprayers to spray all standard paints.
They are suitable for large jobs where time is not a
factor, and also for the professional to touch up after the
large equipment is finished.
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.
AIR GUNS & PRESSURE POTS
Conventional air spray guns for fine finishing. Suitable for
countless industrial and automotive applications. Available in suction, gravity, and pressure feed versions. Each
is available in many different needle sizes.
PNEUMATIC PISTON PUMPS

used for industrial coatings. Applications range from
portable lacquering to plumbed-in automatic systems.

finishing where overspray must be kept to a minimum.
The finish results are equal to or better than conventional
air spray. The turbine systems are self contained and do
