WARNING1) Injection hazard : Airless Painting Equipment can

cause serious injury if the spray penetrates theskin. Do not point the gun at anyone or any part ofthe body. The tip guard provides some protectionagainst accidental injection injuries, but is mostly awarning device. Never put your hand, fingers orbody over the spray tip. Gloves and clothing do notnecessarily offer any protection either. Keep thegun trigger safety lever in locked position when notspraying. Always have the tip guard in place whilespraying.In case of penetration seek medical aid immediately!Note to physician: Injection into skin is a serioustraumatic injury. It is important to treat the injurysurgically as soon as possible. Do not delay treat-ment to research toxicity. Toxicity is a concern withsome exotic coatings injected into the bloodstream.Consultation with a plastic surgeon or reconstructivehand surgeon may be advisable. Be prepared to tellthe doctor what fluid was injected.

2) This system is capable of producing 2800 PSI . Toavoid rupture and injury, do not operate this pump withcomponents rated less than 2800 PSI working pressure(including but not limited to spray guns, hose and hoseconnections).

3) Do not spray paints or other inflammable fluidsindoors which have a flash point below 21 degree C, 70degree F. Keep spray area well ventilated. Beforespraying, turn off all pilot lights and open flames.

4) Wear a respirator which is approved for the productbeing sprayed.

5) Do not use halogenated hydrocarbon solvents in thissystem; it contains aluminium parts and may explode.Cleaning agents, coatings, paints, and adhesives maycontain halogenated hydrocarbon solvents.

Thematerial you are spraying will have a direct effect on theamount of pressure required for the optimum pattern andcoverage to be obtained. We recommend that beforeactually beginning your job, you carefully read thismanual and practice with the sprayer until you feel com-fortable using it.

The Lemmer L-1000 sprayer is also powerful and versa-tile enough to be used with a variety of options (extralengths of hose, extensions, pressure feed rollers, etc.)to make it an even more efficient tool. Ask your retailerabout the recommended accessories for your particulartask.

WHAT’S DIFFERENT ABOUT AIRLESS SPRAYING?

Airless sprayers represent the newest advance in paintingtechnology for homeowners. Results are basically thesame as for compressor-type sprayers, but there areimportant advantages for airless sprayers.

1) Lower Initial Cost

With no compressor, tank, pressure regulator, gasolineengine or large electric motor, an airless is a muchsimpler unit than compressor-type sprayers of similarcapacity.

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 overatomizingthe paint, resulting in less misting. Tighter spray patternmeans less overspray. You can more easily keep thepaint going where you want it to go - not into the air oronto another surface.

4) Faster Painting

Since only paint is being pumped onto surfaces, airlesssprayers will generally paint much faster than compressorunits.

Spray Gun

The spray gun is designed specifically for airless spray-ing. Since there is high pressure, the spray tip and gunvalve are made of tungsten carbide for maximum wearresistance.

As a safety feature, the spray gun can be locked with thetrigger safety lever when you are not spraying. Be sure toread all warnings concerning the high pressures of airlessspraying on pages 3 & 4.

Hydraulic Pump

The hydraulic pump is located at the front of the sprayer,directly under the paint block. It operates as follows: Theelectric motor is connected to an eccentric bearing insidethe hydraulic pump. The piston rests on the bearing. Themovement of the bearing causes the piston to move upand down. When the trigger on the gun is pulled back,this action moves the pump diaphragm. Diaphragmmovement forces the paint through the outlet valve andon through the paint hose and spray gun. The paint goesthrough the spray gun at high pressure, causing it tobreak up (atomize) into fine particles. This gives a smoothand even paint coating. Pressure and delivery rate areregulated by the pressure control knob and the size ofspray tip.

Diaphragm

The diaphragm is the heart of the sprayer. In addition topumping paint, it also serves as a gasket between thehydraulic pump and paint block. As such, it prevents thepaint and hydraulic oil from mixing. The sprayer operatesat 1725 strokes per minute. This means that the dia-phragm forces a “gulp” of paint out the spray gun 1725times every minute.

An insert fits in the inlet hole on the bottom side of thepaint block. This insert reduces wear by protecting thediaphragm from the metal edges of the inlet hole.

The diaphragm is made of flexible, tough plastic. It is notharmed by common solvents.

Pressure Control Valve

The manually operated pressure control knob is on thefront of the hydraulic pump. When the knob is turnedclockwise, oil pressure is increased. When the knob isturned counterclockwise, oil pressure is reduced. Thepressure control knob regulates the pressure on thediaphragm up to 2800 PSI.

Always reduce the pressure (turn knob all the way coun-terclockwise) when cleaning system, or when switchingthe position of the prime knob.

Paint Block

The paint block is located on top of the hydraulic pumpand diaphragm and is fastened with four socket-headbolts. The paint block is simply a valve block with inlet,outlet, and prime valves. These valves regulate the flowof the paint through the block during priming and spray-ing. The inlet and outlet valves work on opposing strokes

GENERAL DESCRIPTION

of the diaphragm to draw in and force out the paint.

The paint block operates as follows: The piston in thehydraulic pump forces hydraulic oil toward and away fromthe diaphragm. This action moves the diaphragm up anddown, forcing paint through the spray gun at high pres-sure.

Prime Valve

The prime valve knob is located on the front of the paintblock. When turned to “prime”, it circulates paint to ventthe air trapped in the paint block out to the hopper. It willcontinue to recirculate the paint until the knob is manuallyturned to the “spray” position.

When the prime knob is turned to “spray”, flow is shut offthrough the return tube and is routed to the paint hose forspraying.

The prime valve also serves to relieve pressure on thesystem during shutdown and cleanup. The pressure isrelieved by turning the prime knob to “prime”.

The prime valve has another important function. It is asafety relief valve. If too much pressure builds up in thesprayer, the prime knob will dump this pressure harm-lessly back into the hopper.

CAUTIONChange the position of the priming knob slowly. Thiswill prevent breaking any valve parts. Always reducethe pressure with the pressure control valve beforeturning the priming valve knob.

Inlet Valve

The inlet valve is located on the top of the paint block atthe front of the sprayer. The paint hopper screws handtight onto this valve. The valve operates automatically tocontrol the flow of paint from the hopper into the paintblock. It does this by opening up when the piston anddiaphragm are on the downstroke, allowing a “gulp” ofpaint to enter the paint block. The inlet valve then closeswhen the piston and diaphragm are on the upstroke. Thisclosing prevents paint from going back through the inletvalve into the paint container. (Inlet valve acts as a checkvalve.)

Outlet Valve

The outlet valve is also located on the top of the paintblock 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 ofpaint out into the spray hose and through to the spraygun. When the diaphragm and piston act to “gulp” morepaint, the outlet valve closes. The closed valve prevents(checks) paint in the spray hose and spray gun fromreturning to the paint block.

The inlet and outlet valves work in harmony with thediaphragm and piston to provide a constant flow of highpressure paint to the gun.

8

This Paint Sprayer comes already assembled except forthe paint hopper, high pressure airless hose, and spraygun. (See fig. 1, page 6) An adjustable wrench is theonly tool required for assembly. Do not plug the sprayerin until it is completely assembled.

Hopper installation

The hopper assembly consists of the hopper, hopperreturn tube, and hopper screen. Screw the hopper ontothe inlet valve. Screw the threaded end of the hopperreturn tube into the side of the paint block. Put the otherend in the hopper. The hopper connections need only behand tight but tight enough to prevent air from beingdrawn in.

Paint hose installation

Your sprayer is furnished with a 25 foot conductive highpressure paint hose. Never add to or substitute with non-compatible hose. For proper hose, see accessories onpage 19.

Screw the paint hose onto the outlet fitting on the side ofthe paint block and tighten with a wrench.

Spray gun installation

1) Screw the spray gun onto the end of the paint hoseand tighten with a wrench. Lock the trigger.

2) Screw the spray gun onto the end of the paint hoseand use two adjustable wrenches to tighten. Lock thetrigger.

Spray tip installation

PREPARE FOR OPERATION

CONTROLS

1) On-Off Switch is located on the side of the electricmotor.

2) Pressure Control Knob is manually operated andlocated on the front of the hydraulic pump. When theknob is turned clockwise, hydraulic pressure isdirected toward the diaphragm. When the knob isturned counterclockwise, hydraulic pressure is re-duced. The pressure control knob regulates thepressure on the diaphragm from 0 PSI when turnedfully counterclockwise to 2800 PSI when turned fullyclockwise.

Always reduce the pressure (turn knob all the way out- counterclockwise) when cleaning or switching theposition of the priming knob.

3) Priming Knob is located on the front of the paintblock. It is manually turned to the “P” or “S” position.When on “P” (prime) it serves to rid the sprayer of airby directing the initial air volume of the inlet valveback into the paint hopper. It will continue to do thisuntil paint comes through and it is manually switchedto the “S” (spray) position.

The priming valve also serves to relieve pressure onthe system during shutdown and cleanup. Thepressure is relieved by turning the priming knob to“P”.

When the priming knob is turned to “P” (prime), paintis drawn from the hopper into the paint block. Thepaint block then routes the paint through the returntube back to the hopper. This primes the paintsystem. When the priming knob is turned to “S”(spray), flow is shut off through the return tube andyou can spray.

NOTE: Newer L-1000 models use symbols instead of“P” or “S” position as shown below.

CAUTIONCHANGE THE POSITION OF THE PRIMING KNOBSLOWLY. THIS WILL PREVENT BREAKING ANYVALVE PARTS. ALWAYS REDUCE THE PRESSUREWITH THE PRESSURE CONTROL KNOB BEFORETURNING THE PRIMING KNOB.

POWER SUPPLY, MOTOR CARE

The motor is located at the rear of the sprayer and isconnected to the hydraulic pump. It is furnished with a 3-wire electric cord. The third wire (ground) should neverbe cut off. Any extension cords used must also be 3-wire,14 gauge minimum with a 3-wire plug that will plug into a3-wire grounded electrical outlet. Do not use 2-wireextension cords. The maximum length of all cords andextension cords used should not exceed 100 feet. If youneed to spray farther away from a power source, usemore paint hose, not more extension cords. Shorterextension cords will assure maximum electrical power forproper operation. Cords and extension cords should beprotected from vehicle traffic and sharp cutting edges orobjects. Any worn or damaged cords should be replacedpromptly.

The motor should always be kept clean and dry. Paintacts as an insulator. Therefore, too much paint on themotor will cause it to overheat.

Electric service must be 115 VAC, 60 Hz, 15 Amp mini-mum circuit.

PAINT STRAINING AND THINNING

When a container of paint is exposed to the air for aperiod of time, a “skin” may form on top. This “skin”should be removed. If necessary, the paint should bestrained through a strainer.

Under normal conditions, paints used with this airlesssprayer do not have to be thinned. However, there is apossibility that you may use paint that is too thick to besprayed. In this case you will have to thin the paint. As ageneral rule all paints need about 5% thinning, whereaslight materials such as linseed oil, and clear lacquers donot require any thinning.

When thinning paint to spraying consistency (viscosity),use appropriate thinner - water for latex paint, mineralspirits for oil base paints (or consult the instructions onthe paint can for proper thinner).

SELECTING CORRECT TIP SIZE

The spray tip provided with your new system is an aver-age size for general painting. After a few jobs, you maywant to select a tip more suited to your liking. Tips mustbe the correct size for proper atomization, and to providethe operator with the right speed. The chart on page 11will give you a general idea on how to choose the right tip.If you need some more help on choosing tips, please askone of our trained personnel in any Lemmer location.

OPERATION

START UP PROCEDURE

1) Check oil level as described on page 15.

2) Check for suction. Before putting the paint hopperon, check for suction at the inlet valve. To do this,turn the priming knob to “P” (prime) position and startthe sprayer with pressure control knob counterclock-wise (minimum pressure). Place the palm of yourhand over the inlet valve and slowly turn the pressurecontrol knob clockwise until suction is felt. Turnpressure control back to minimum and re-installhopper. (If no suction was felt, free the inlet valve asdescribed on page 17. If this does not help check“Bleeding Hydraulics” on page 16.

3) Be sure all fittings are tight , and make sure guntrigger is in safety lock position.

4) Prime pump with thinners. Pour a small amount ofthinners (which is compatible with paint about to besprayed) into the hopper. Turn pressure up until it iscirculating through the return tube. Turn pressureback to minimum and discard the thinners. Now youare ensured that paint will pump through with nopossibility of gelling due to incompatibility.

5) Prime pump with paint. Pour paint into hopper (afterit has been prepared). With priming knob in primeposition, turn pressure up and let the paint circulatethrough the return tube for about 2-3 minutes. Thiswill ensure all air is bled out of the paint block.

6) Switch to spray. Turn pressure back to minimumand switch priming knob to spray.

7) Build up pressure. Slowly turn the pressure up whilewatching for leaks at connections.

8) You are now ready to spray! Disengage safety leveron the gun. Remember this is high pressure-neverpoint the gun at anyone. Pull the trigger and sprayout the air or thinners in the system until the paintreaches the tip.

SHUT DOWN PROCEDURE

Always reduce pressure, slowly turn prime knob to prime,trigger gun to release pressure build up in hose, and turnmotor off. Never leave any pressure in the systemwhen not in operation.

ADJUSTING SPRAYING PRESSURE

The ideal way of spraying is to have a perfect spraypattern with the lowest possible pressure to keep over-spray to a minimum. These example spray patterns showthe effect of pressure and tip size.

IF TIP BECOMES CLOGGED

1) Rotate the tip to the “Clean” position.

2) Pull trigger and spray. This should clear the tip of anyblockage.

3) Rotate the tip back to the “Spray” position and con-tinue spraying.

4) If the clogging continues, clean or replace the gunfilter and see the “Getting Started” section of thismanual for instructions on straining and thinningpaint.

HOW TO SELECT TIP SIZE AND PROPER FILTER(BASIC INFORMATION)

i

i

i

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 atip is used for some period of time, it can wear beyond the maximum size recommended for the pump, whichwill 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 var-nishes 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 protecta given size of tip. Pick the tip for the type of paint and job being done and then choose the filter to protectthat tip.

Tip chart example: Latexstain is being sprayed ontoa fence. The paint is fairlythick (like a very heavymotor oil) and the L-1500is the spray machine. Themaximum tip is a .015 foran L-1500. Draw a linealong the .015 tips asshown below. Everythingabove the line is sprayablewith the L-1500. Now justchoose the fan width. Forfences a 6” width will givea lot of control, so theintersecting best choicewould be a 3-15 tip with ayellow gun filter.

Measure the paint’s viscosity as follows: (note, paints thatare intended to be rolled should be thinned for air or airlessspraying. A general rule of thumb is 5 to 15% for latex andoils, 30% or more for fine finishes. (consult your paintsupplier 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.d) The time recorded is the paint’s viscosity.

Figure 11. - Result of flexing wrist while spraying.

••You can learn to spray paint as easily as you canlearn to paint with a brush and roller. Get profes-sional looking results by following the spray tipsbelow.

WARNING

DO NOT BEGIN SPRAYING BEFORE READING THISSECTION AND ALL PREVIOUS SAFETY INFORMA-TION.

1. KEEP THE GUN PERPENDICULAR TO THE SUR-FACE

Always hold the gun perpendicular to the surface withthe tip approximately 12" from the surface. If held atan angle (up and down or side to side) paint will buildup 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 keepingthe gun perpendicular to the surface. (See figure 10)Do not move the gun by flexing your wrist. Fanningthe gun will cause excessive overspray and unevencoverage. (See figure 11). If the rate of speed is notcomfortable for you;

a) To slow down , either lower the pressure, or use asmaller spray tip.

b) To speed up , either increase the pressure, or usea larger tip. (A larger volume pump is required if youwant to exceed the L-1000's maximum .017 limit).

3. START MOVING THE GUN BEFORE TRIGGERING

To get smooth overlap and prevent initial paintbuildup, start your stroke movement before pulling thetrigger. At the end of the stroke release the triggerbefore stopping.

NOTE: To assure uniform paint coverage, overlapeach stroke by 40% - 50%.

4. INTERMITTENT USE

If you are spraying and decide to stop for severalminutes, lock the spray gun trigger and submerge thetip in a container of the appropriate solvent. This willprevent paint from hardening in the tiny spray open-ing and clogging the tip. Be sure to release thepressure by turning the prime knob to prime andswitching the pump off.

CLEANING INSTRUCTIONS

2. REMOVE AND CLEAN SPRAY TIP. With trigger lockengaged, and unit turned off, remove spray tip, filterand washer from gun and place parts in a containerof suitable solvent.

3. PUMP PAINT OUT OF HOSE. Pour suitable cleaningsolvent into the hopper and prime the pump. Cleanthe hopper with a brush or rag. Lower pressure andturn prime knob to “spray”. Disengage trigger lockand trigger gun into the paint can until thinner ap-pears. It is best to submerge the nozzle in the paint orthinner to prevent splashing.

Caution: Conductive , metal con-tainers must be used whenflushing flammable fluidsthrough the system. A metal partof the spray gun should be heldfirmly against the grounded metalpail when relieving the pressure from the gun.

4. FLUSH HOSE AND PUMP. Continue pumpingsuitable solvent through the pump, hose, and gun intoan empty container until it runs clear. Pump furtheruntil all fluid is out of the system. Rinse and wipeclean any paint on the exterior.

5. CLEAN FILTERS. Remove the hopper screen andgun filter, and rinse both clean. Use an old toothbrushto remove any sediment.

6. LUBRICATE VALVES. (If an oily solvent was used incleaning, 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 anextended period of time, drain all the water out of thehose, gun, and pump. Tungsten carbide parts in thevalves will corrode if left in water for long periods oftime. With the pump running in the prime mode, placea few drops of light oil into the inlet valve. Let thepump run until it spits oil drops out the return fittings.This will displace any remaining water and lubricatethe valves for storage. With the motor off, remove thegun and place some oil into the gun. Trigger the gununtil oil seeps out the ball and seat. A few drops of oilon 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 orkink the hose. Roll diameter should be about 2 feet. Itis best to hang the coiled hose on a bracket or largenail out of the way to keep it from being damaged.The pump and gun should be stored on a shelf out ofthe way. (Make sure that the gun safety lever isengaged). They should be kept in a cool, but not cold,dry place and clear of traffic to avoid accidentaldamage. The electric cord should be wound on itselfand tied.

AS WITH ANY SPRAY EQUIPMENT, YOUR SPRAYERMUST BE CLEANED PROPERLY OR IT WILL NOTOPERATE PROPERLY. CLOGGED VALVES ANDFILTERS ARE THE MOST COMMON CAUSES OFPROBLEMS. IF FOLLOWED, THESE GUIDELINESWILL INSURE TROUBLE FREE PERFORMANCEFROM YOUR SPRAYER.

WARNINGDO NOT CLEAN THE SPRAY GUN OR TIP ASSEMBLYUNLESS THE PRESSURE HAS BEEN RELEASEDFROM THE SYSTEM. SEE PAGE 3 & 4 FOR FURTHERPRECAUTIONS.

CAUTIONCLEAN WITH WATER IF LATEX IS USED. CLEAN

WITH MINERAL SPIRITS FOR OIL BASED PAINTS.

NOTEWe recommend running light oil or mineral spirits throughthe unit before storing. When using latex paints, makesure the unit has been completely cleaned before storingwith mineral spirits. Mineral spirits react with latex paint toform a jelly-like substance which can damage your pump.

Figure 12. - Oil valves before storing.

1. PUMP OUT REMAINING PAINT. Flex the returntube out of the hopper and hold it above a paintcontainer. Turn prime knob to prime position, turnmotor on, and increase the pressure until it is pumpeddry. Move the return tube back into the hopper.

15

MAINTENANCE & SERVICE

WARNINGTURN POWER OFF AND RELEASE ALL PRESSUREFROM THE UNIT BEFORE DOING MAINTENANCE.

Paint hose:

Periodically inspect the paint hose. If the hose is kinked,cut, or worn, it must be replaced . It cannot be repaired. Ahose bursting at 2800 psi can cause significant damageto property AND cause a serious injury if the spray injectsthe skin. Replace with a grounded or conductive airlesspaint hose that is rated for at least 2800 psi “working”pressure.

Spray gun

The filter should be cleaned or replaced after each use tominimize tip clogging problems. If the gun valve becomesworn and begins to leak, it should be replaced.

Diaphragm:

After finishing your first job with the sprayer, wait untilit has completely cooled down. Then tighten the 4 paintblock bolts with a 6mm allen wrench. The bolt are lo-cated on the top of the paint block as shown in figure 13.Tighten opposite bolts in turn as shown. If you use atorque wrench, tighten to 25 ft./lbs. (300 in./lbs.) torque.Thereafter, tighten the paint block bolts every 3-4 opera-tions. One lockwasher should always be used with eachof the 4 paint block bolts.

Proper torque on the paint block bolts assures efficientoperation of the diaphragm and prevents hydraulic oilfrom leaking out between the paint block and hydraulicpump. Do not over-torque or under-torque!

Testing diaphragm:

1. Remove inlet valve.

2. Turn motor on briefly and using the blunt end of a penor pencil, feel if the diaphragm is moving.

3. If it is not moving, check oil level. If oil level is OK.,bleed the air from the hydraulics. If hydraulics areOK., change the oil. If paint is mixed in with the oil,the diaphragm is ruptured and requires replacementand the internal hydraulic system requires cleaningas detailed in next paragraphs.

Diaphragm replacement:

1. Remove the paint block assembly. Remove dia-phragm assembly. With the unit lying on its back,remove the hydraulic pump front cover. Drain the oil.

2. If paint has contaminated the oil reservoir, it must becleaned and the oil replaced. (Note: if strong thinnersor strong paints are found in the hydraulics, check theoil seal for swelling and check the motor inside fordamage due to varnish softening). All internal partsmust be cleaned, i.e. bearing, hydraulic piston,pressure vessel, pressure regulator, return tubes, andoil elbow. Improper cleaning of these internal compo-nents may cause rapid hydraulic pump wear and maycause eventual replacement. Replace the oil suctiontube with a new one. The pressure regulatorshould be disassembled and properly cleaned,the pump's pressure will then require resetting bytrained personnel and the use of an accuratepressure gauge . Clean and dry paint block assemblyand housing ring pressure grooves. Reassemble witha new diaphragm in reverse sequence. (See belowfor proper torque sequence and proper oil refill level)

3. Tighten paint block assembly to 23 ft/lb torque usinga progressive ‘X’ pattern. See figure 13.

4. Bleed the pump. See page 16.

Checking hydraulic oil level:

Check the hydraulic oil level before each use and afterevery 20 run hours. The sprayer was shipped with theproper amount of hydraulic oil in the reservoir, (hydraulicpump). However, the oil should be checked beforestarting. Check the oil by standing the sprayer up so thatit rests on the rear of the motor. In this position thehydraulic housing will be up. Remove the oil filler plug onthe hydraulic housing face plate. Stick a sharpenedpencil or other long, thin object down the hole. The oillevel should be approximately 1/2" from the tip of the faceplate. Oil capacity is approximately 19 ounces. Use onlyNuto H 32 hydraulic oil (order number L034-120).

Changing hydraulic oil

Change the hydraulic oil after the first 20 run hours andevery 50 hours thereafter. To change hydraulic oil,proceed as follows:

1) Remove the oil filler plug from the hydraulic housingface plate.

2) Drain out the old hydraulic oil.

3) Clean the sprayer by running it with a filling of about2/3 pint of cleaning fluid in the hydraulic housing.Run it for only a few seconds. Do not use any clean-ing fluid that is not compatible with rubber. (Varsol isan excellent cleaning fluid)

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

5) Fill hydraulic housing with approximately 19 ouncesof hydraulic oil. Use only hydraulic oil order numberL034-120. (1 litre)

6) Since air may enter the system when the oil ischanged, the sprayer may have to be vented (bled).To bleed out the air, see page 16.

You will also have to bleed the air out of the system if youremove the paint block or go into the hydraulic housing,or if the sprayer loses prime due to rough handling.

Bleeding air from hydraulics

You will have to follow this bleeding procedure when youchange hydraulic oil, if you remove the paint block, or gointo the hydraulic housing, or if the sprayer loses primedue to rough handling.

1) Turn pressure control knob all the way counterclock-wise, turn priming knob to “P”, and let sprayer run afew minutes. It is sometimes helpful to turn ON-OFFswitch ON and OFF to assist in bleeding.

2) Now turn pressure control knob clockwise to primethe pump. If sprayer is warm from use, loosen oil fillplug. When sprayer is primed, suction can be feltwith the palm of your hand. This may take 2-3minutes. If sprayer does not prime, turn pressurecontrol knob counterclockwise and repeat the proce-dure.

Pressure control valve

The pressure control valve is preset at the factory for yoursafety and is not adjustable except by a Lemmer servicecentre. However, the valve is easily replaced on the job. Ifthe pump cannot pressurize to 2800 +/- 250 psi when thegun is not triggered and there are no leaks or flowthrough the prime valve, a new pressure valve cartridgeshould be installed with a new washer and torqued toapproximately 50 in-lbs. The pump should be bled afterinstallation. See below.

Prime valve

If the prime valve is not properly cleaned after each use,It may stick open. If this occurs, paint will flow through thereturn hose when the valve is turned to “spray”. Workingpressure will then slowly begin to drop as the valvewears. A new valve should be installed with new washersand torqued to 100 in-lbs.

Figure 14. - Prime valve parts.

Replacing prime valve o-ring.

1) Switch prime valve to spray position.

2) Carefully punch out pin (1), from the end which isslightly smaller. (Newer models use 2 set screws.)

3) Pull off knob. (2)

4) Unscrew cam (3) with a pair of long needle nosepliers using holes provided. Newer models have atwo piece cam as shown in the parts diagram onpage 22.

5) Remove star washer. (4)

6) Pull shaft (6) and spring (5) straight out.

7) If replacing the entire valve, remove seat (8) and seatseal (9). Newer models do not use a seat seal.

8) Clean all parts and install new O-Ring (7). See page22 & 23 for order numbers of the two types of o-rings.

9) Grease o-ring, install shaft and spring.

10) Insert washer into cam, carefully thread on, andtighten.

11) Line up hole in shaft with cam dip. (On set screwtype, fully bottom, pull back slightly to give about1mm play, then tighten screw. Ignore following step.

12) Slide knob on and into spray position, make sureholes line up, and press pin in. (Narrow end first)Note: Diagram 18 shown in prime position.

Inlet and Outlet Valves, General:

The inlet and outlet valves will wear. The rate of weardepends on the type and quality of paint you use. As thespraying pressure and vacuum drop, the outlet valve andinlet valve should be replaced. However, first be sure thatthe tip is not worn; this can cause a drop in sprayingpressure as well. New valves should be installed with newwashers 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 withpaint being used.

2) Turn pressure control knob to maximum and primingknob to prime. Start motor.

3) Carefully push the inlet valve nut up and down re-peatedly with a screwdriver as shown in figure 15.

4) Check suction with the palm of your hand. Note: Thesuction felt after thinners has gone through will not beas great as if oil had just been pumped through.

5) If this does not solve the problem see “cleaning theinlet valve”.

Testing inlet valve (motor off)

1) Remove inlet valve (see “cleaning inlet valve”).

2) Clean thoroughly.

3) Dry completely and stand upright on dry paper. Fillwith thinners.

4) If thinners empties quickly replace inlet valve.

5) If thinners leaks slowly, proceed to “testing inlet valve(motor on)”.

Testing inlet valve (motor on)

1) Build pressure up to maximum (with thinners).

2) Turn motor off. Do not bleed pressure or adjustpressure control knob.

3) Turn motor on for 2 seconds and turn off immediately.If motor buzzed and did not start, inlet valve (andhydraulic piston) are functioning properly. If motorstarted, replace the inlet valve.

4) If, with a new inlet valve the motor starts, return themachine to your nearest Lemmer Service Centre forservice.

Cleaning or replacing inlet valve

1) Turn motor off.

2) Remove valve with a 27mm socket or an adjustablewrench.

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 inletvalve to more than 40-50 ft./lbs.

5) If this does not solve the problem, check “cleaningoutlet valve”.

MAINTENANCE & SERVICE (CONTINUED)

Cleaning outlet valve

1) Remove outlet valve end cap with a 19mm socket oran adjustable wrench. (See figure 16)

2) Remove cap seal, spring, and ball. If ball is stuck, tipthe machine and use a small screwdriver to “pluck” itout.

3) Clean all parts including the outlet valve seat still inthe machine. Check the spring for wear and replaceif necessary. Note: Spring tension is critical, only useoriginal parts.

4) Grease the cap threads and spring. Drop the ball intothe seat, place cap seal and spring onto the cap andtighten down. Caution - Do not tighten more than18 ft./lbs.

Replacing outlet valve parts

1) Remove outlet valve end cap with a 19mm socket oran adjustable wrench.

2) Remove cap seal, spring, and ball.

3) Remove outlet valve seat with a 6mm allen wrench.Remove seal with a “hooked” tool.

4) Clean and examine all parts for wear. Replacenecessary parts.

5) Always use new seat seal. Re-using this seal couldcause damage resulting in paint block replacement.

6) Install new seat seal.

7) Grease valve seat threads and firmly tighten to 18ft./lbs. Note: If too loose, paint may “pressure cut”the seal and the paint block; if too tight, the threadsmay strip. Both would cause damage to the paintblock, so be certain of your torque.

8) Install the ball. Grease the spring and the capthreads. Place cap seal and spring onto cap andtighten down to no more than 18 ft./lbs.

* If applicable

• To clean gun: flush the inside by spraying proper solvent, and wipe the exterior. (It is notneccessary to disassemble gun components under normal circumstances).• Injection hazard : Airless Painting Equipment can cause serious injury if the spraypenetrates the skin. Do not point the gun at anyone or any part of the body. The tip guardprovides 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 notnecessarily offer any protection either. Keep the gun trigger safety lever in locked postionwhen not spraying. Always have the tip guard in place while spraying.

In case of penetration seek medical aid immediately! Note to physician : Injectioninto skin is a serious traumatic injury. It is important to treat the injury surgically assoon as possible. Do not delay treatment to research toxicity. Toxicity is a concernwith some exotic coatings injected into the bloodstream. Consultation with a plasticsurgeon or reconstructive hand surgeon may be advisable. Be prepared to tell thedoctor what fluid was injected.• Do not use halogenated hydrocarbon solvents in this system; it contains aluminiumparts and may explode. Cleaning agents, coatings, paints, and adhesives may containhalogenated hydrocarbon solvents. Don't take chances, consult your material supplier to besure. (ex: methylene chloride and 1,1,1 - Trichlorethane)

• Follow shut down procedure beforeservicing or cleaning equipment. (see#1 overleaf)• This instruction sheet is only asupplement to your system operatinginstructions. Read your system manualbefore operating any high pressureequipment.• Remove filter for cleaning , thenreinstall and hand tighten the handle.

• Caution : When a flammable liquid is sprayed there may be danger of fire or explosionespecially in a closed area.• Use extreme caution when cleaning spray tip guard. DO NOT try to wipe off build uparound 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 offpump, releasing fluid pressure, and locking the trigger safety lock.• Conductive metal containers must be used when flushing flammable fluids throughthe system. Always flush at low pressure with spray tip removed. A metal part of the spraygun must be held firmly against the grounded metal pail when flushing or relieving pressurefrom 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.

11) Lightly grease the packing (pos. 11) and exteriorthreads of the ball spring assembly. Push firmly intogun body and tighten 7-10 ft. lbs.

12) Examine the trigger pins for wear and equal length.Lightly grease and install.

13) Install retainer cap on rear of gun and install lockingnut. Tighten locking nut until approximately twothreads show out rear of the nut.

14) Thread gun handle into gun body.

15) Lightly grease threads of seat. Install trigger guardover open end of seat. Hold gun trigger in openposition and install seat. Tighten to 30-40 ft. lbs. andrelease trigger.

16) The retainer cap should have a bit of slack in it andshould not be bottomed against the gun tightly. Thetrigger should have 3/8" slack at the bottom of thetrigger before engaging against the trigger pins.

This slack is very important to the correct operation ofyour gun. The gun and safety lock will not workcorrectly if this step is not performed correctly.

To increase slack , loosen the locknut a little and testslack again.

To decrease slack , tighten the locknut a little andtest slack again.

With too much slack, the gun may not turn on, but thesafety lock will work fine. With too little or no slack,the gun may be permanently ON and the safety lockdoes nothing.

DO NOT RUSH OR IGNORE THIS STEP, COR-RECT OPERATION OF THE SAFETY REQUIRESPROPER ADJUSTMENT OF TRIGGER SLACK.

17) Install tip attachment onto gun. Remove gun handle,install spring and filter, lightly grease threads and re-install.

18) Place trigger in LOCK position. Install gun to hose,tightening securely. Gun is now ready for testing anduse.
