H.E.R.O. AIRLESS SPRA Y P AINTING

Welcome to the world of H.E.R.O. airless paint spraying. We are sure you will enjoy owning and operating
your new H.E.R.O. model 3000. With H.E.R.O. airless spray equipment you will avoid the inconvenience
and mess of over spray. You are spraying paint, not air, and the paint is driven to the painting surface in a
clean, fan shaped spray which penetrates all cracks and corners. To attain these results, you must adjust the
pressure as low as possible. We recommend that you become familiar with your H.E.R.O. unit. Discuss with
your dealer the useful accessory items he has to offer - various types of tips, extension poles for hard to reach
areas, extra hose, etc. Use of accessory items is often the difference between a good job and an excellent one!

OPERATING INSTRUCTIONS

WARNING

Do not attempt to operate this machine until you have read and understood all safety precautions and
operating instructions. Equipment and chemicals when used improperly can be dangerous.

Your H.E.R.O. airless sprayer has been fully factory tested prior to shipment.

BEFORE STARTING YOUR H.E.R.O. PUMP....

CHECK to ensure that the shipping seal has been removed from under the cap on the hydraulic tank.

Hydraulic tank should be at least 3/4 full of H.E.R.O. LVO hydraulic fluid.

CHECK all fittings and connections in the pump system, hose, and gun to ensure that they are tight.
CHECK to ensure t hat t here is a spray tip in the gun, and that the tip is t he correct si z e for the coat ing you

are to spray. ( There are various tips available, for each type of coating or configuration. See " Airless Spray
Tip " on page 12/13 , for proper tip selection.
CHECK to ensure that you have H.E.R.O. strainer bags, H.E.R.O. Wonder Wash, appropriate thinner for
the paint, a waste container, and any other accessories you may require for the job.
CHECK to ensure that you have adequate extension cord size and length if the machine cannot be situated
immediately next to an electric outlet. Distances up to 50 feet require #12/3 wire grounded cord, up to 100
feet require #10/3 wire grounded cord. DO NOT exceed 100 feet of extension cord. If distance is greater,
obtain and install extra length of H.E.R.O. airless spray hose.

grounded cord, up to 50 feet or #10/3 wire grounded cord, up to 100 feet. DO

NOT EXCEED 100 FEET OF EXTENSION CORD. If distance is greater,

purchase and install additional lengths of airless sp ray hose.
12 Turn motor switch "on".
13 Turn prime valve handle (ref# 43) counter clockwise until fully open. Allow

thinner to circulate back into the siphon pail for a few minutes. Then turn the prime

valve knob clockwise to close the valve ( close tightly ), and direct the flow to the

paint hose and gun. Leave the pressure setting low.
14 Trigger gun into waste container.
15 Pour paint through strainer bag into siphon pail.
16 Repeat steps 13 and 14, until paint flows freely. NOTE; Never turn prime

valve back to "prime" position when the unit is und er pressure.
17 Spray a test pattern. Begin by spraying a test pattern onto old newspaper or

other scrap material.
18 Increase the pressure, slowly at first, by turning the pressure control knob

clockwise. Continue increasing the pressure until the spray pattern is unif ormed

from top to bottom, with no heavy area s. Secure pr essure control se tting, by

turning the silver lock ring (ref# 76) counter clockwise until snugly against the

face of the pressure control knob. If heavy areas are still v isible a t maximum

pressure setting, thin the paint with the correct thinner, according to the paint

manufacturer's recommendations.

FLUSHING THE UNIT AT SHUTDOWN

OR COLOR CHANGE

If shutting down for a short period of time, it is sufficient to trigger the gun
to relieve pressure. Then set the safety lock on gun to "locked" position with
the gun locked closed and immerse the gun in a container of the correct
thinner for the paint you are spraying.

1. Remove spray tip from gun.

2. Turn pressure control knob counter clockwise to low pressure setting.

Only use sufficient pressure to allow material to move through the

sprayer. DO NOT operate at or near full pressure.

3. Remove siphon assembly from paint container.

4. Trigger gun, back into paint container, until unit runs dry.

NOTE: Pump and spray hose will continue to contain paint. This paint

may be recovered by placing prime hose into paint container and draining

the remainder while re-priming with cleaning fluid. See step 5* and 6*.

5. Place siphon assembly in container of correct thinner, for the spray

product being used,, and prime the pump as shown in step 13, of

"Spraying". *See special notes from step 4. Allow thinner to circulate

back into the container for a few minutes to flush the prime valve.

6. Close prime valve.

7. Trigger gun into paint container until thinner comes through. *See special

notes from step 4. Re-direct flow into waste container and continue

spraying until thinner runs clear. Heavily soiled thinners may have to be

changed to complete cleaning job.

8. Lift siphon assembly and allow pump to run dry.

9. Repeat procedure using a gallon of H.E.R.O. Equipment Wonder Wash

solution. If not using Wonder Wash, unit must not be stored with water.

Only store with a non corrosive material ( Paint thinner, solvent ).

10. Switch unit "off" and trigger gun to relieve remaining pressure.

11. Remove and rinse gun handle filter in corr ect thinner.

SPECIAL STORAGE INSTRUCTIONS

In areas where the sprayer is NOT used 12 months of the year, special
preparations must be used for winter or off season storage. Because solvents
evaporate quickly, they should not be used for long term storage. A petroleum
based solution ( solvent and oil ) should be used as an extended storage
material. DO NOT allow storage solution to freeze in the sprayer.

H.E.R.O. Equipment Wonder Wash, available from your H.E.R.O.
distributor, will provide the added cleaning benefits of solvent at a much
lower cost. Suitable as a short term ( 1-2 days ) storage solut ion only

 Alway s follow flushing and cleaning instructions exac tly.
 I n hot weather, locate unit in shade.
 Reg ularly check the level of H.E.R.O. LVO hydraulic fluid in the hydraulic tank. It should be kept near

full, top up as needed with only genuine H.E.R.O. LVO hydraulic fluid.
 Crankshaft eccentric bearing should be greased at regular intervals consistent with hours of use. Use
MO-2 grease ( i.e. common auto grease) approximately every 10 hours of operation.
 If you wish to power your H.E.R.O. airless sprayer with a generator, it must be a minimum of a 4500
watt generator, in good operating condition.
NOTE; An electric to ol must be powered by a generator which has an output wattage of at least three
times the maximum draw of the motor under full load.
 A minimu m 50’ and a maximum of 300’ of airless spray hose may be used.
NOTE: 50’ x 3/8” paint hose ( part # 117 ) should be used for every 50’ x 1/4” paint hose
( part # 114 ) over 100’.
100’ total length of paint hose = 2 of 50’ x 1/4” paint hose.
150’ total length of paint hose = 2 of 50’ x 1/4” paint hose and 1 of 50’ x 3/8 paint hose.
200’ total length of paint hose = 2 of 50’ x 1/4” paint hose and 2 of 50’ x 3/8 paint hose.
250’ total length of paint hose = 3 of 50’ x 1/4” paint hose and 2 of 50’ x 3/8 paint hose.

AIRLESS SPRA Y PAINTING
SUGGESTIONS AND TECHNIQUE

A good airless spray application is the result of many factors. Surface preparation, which includes cleaning

and degreasing, priming, material compatibility, quality finish product and correct application technique, are
all important to the finished re sults.

The key to all good applications is a good spray gun technique. The finished results are what the client will
look at and base his opinion on. Your skill and abilities are as important as good equipment and good paint.
Proper application techniques can easily be learned by using the following simple guidelines. If you are not
familiar with the basic spray techniques we recommend that you study this portion of the manual and
practice the techniques shown. Practice your technique on scrap cardboard or old newspaper until you feel
confident.

FOR EXCELLENT RESULTS, READ AND PRACTICE THESE TECHNIQUES

1. Always strain all paint through a H.E.R.O. strainer bag.
The most common reason for airless sprayers to malfunction is foreign matter jamming the valves or
plugging the tip. Always strain the paint before putting throug h the pump.

2. Always spray at the lowest pressure setting which will provide a uniform spray fan. (fig. 1, page 11)
Adjust pressure control knob so that paint is completely atomized . Insufficient pressure will result in
"tailing". Too much pressure will result in excess fog and over spray, excess tip wear, and increased
sprayer wear and tea r. See setting up to spr ay , page 5.

3. Always spray at right angles to the surface being sprayed. (fig. 2, page 11)
Angling or arcing the nozzle toward the surface will cause uneven coverage and excessive over spray.

4. Always hold spray gun 12-15 inches from spray surface. (fig. 3, page 11)
Too close and the fan width will be reduced a nd material will be a pplied too he avily (runs).
Too far from the surface and you will have excessive over spray and light coverage (transparent).

5. Always move the gun parallel to the surface being sprayed, at a consistent speed.
This avoids uneven coverage (thick or thin areas).

6. Always start the spray stroke before triggering the gun and release the trigger before completing the
stroke. (fig. 4, page 11)
This avoids heavy build up of paint at either end of the spray stroke.

7. Always lap your spray pattern by one half. (fig. 5, page 11)
This assures full coverage of the surface being painted.

AIRLESS SPRAY PAINTING SUGG ESTIONS AND TECHNIQUE

SPRAY TIP SELECTION

TIP SIZE FOR APPLICATION OF
.021 Exterior Latex on large unobstructed areas. (max. size allowed) ( 60 OZ. )

.018 Interior Latex, Exterior Latex, Shake Paint, Exterior Flat Paints. ( 46 OZ. )
.015 Alkyd Flat Enamel, Interior Latex, Semi-Gloss Enamel, Stains. ( 30 OZ. )
.013 Fine ground Gloss Enamels, and good quality Stains. ( 23 OZ. )
.011 Clear Varnishes and Lacquers. ( 15 OZ. )
.009 Clear Varnishes and Lacquers. ( 10 OZ. )

NOTE: The above volumes achieved with gun wide open for 1 minute and pump spraying at 2000 psi.
All volumes are approximate. To test worn tips, spray water through the tip at 2000 psi. for 1 minute.
Spray into bucket and weigh amount (less weight of bucket). If it is substantially greater than what is
listed above, then the tip should be discarded or reclassified. As a tip wears, the hole gets larger and the
fan pattern becomes narrower.

ORIFICE SIZE

All tips are rated by the size of the orifice or bore size. The bore size is measured in thousandths of an inch
( .018 = 18 thousandths of an inch ). The size of tip required is based on the consistency of the material to be
sprayed. The thicker the paint, the larger the tip size required. Always consult the product label or ask the
paint retailer for the manufa cturer's r ecommenda tions with reg ard to prope r tip sizes.

FAN WIDTH

Fan width or pattern width is determined by the spray tip's "fan width" classification. This size is measured in
inches, and is determined when spraying 12 inches from the spray surface. Various methods of noting the fan
widths are used by tip manufacturers. Ask your distributor for assistance.

NOTE: Two tips having the same tip size, but different fan widths will deliver the same amount of paint
over a different area (wider or narrower strip). A spray tip with a narrow pattern width makes it easy to
spray in tight places. Use only good quality, high-pressure tu ngsten carbide s pray tips.

SPRAY TIP REPLACEMENT

During use, especially with Latex paint, high pressure and material abrasion will cause the orifice to grow
larger. As the orifice grows larger, the fan width grows smaller. Replace tips before they become excessively
worn. Worn tips waste paint, cause over spray, make cutting in difficult, and decrease sprayer performance.

NOTE: When using Latex paint, a spray tip will wear at the rate of one size for approximately every 100
gallons of material sprayed.

An excessively worn tip can be the cause of apparent operating problems with the unit. If a tip is worn
past the aperture size which the unit can support, pulsation will become evident in the spray fan/pattern.
Added strain is placed on the Hydrapulse membrane as it attempts to keep the spray pressure consistent.
When the tip wears beyond .023, its is releasing more material than the unit is bringing in. The natural
reserve of product in the paint chamber is reduced and harm to the membrane begins. ALWAYS check
your tips for wear when trouble shooting the equipment. The 3000 can support up to a maximum of
a .023 tip.
