H.E.R.O. AIRLESS SPRAY PAINTING
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 4500D linestriper. The H.E.R.O. 4500D Linestriper is a versatile painting unit that
is suitable for both line striping applications and regular airless painting applications.
With H.E.R.O. airless spray equipment you will avoid the inconvenience and mess of overspray. 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!

UNIT SET-UP
Due to the flexible design of the 4500D, the set up of the unit may take on various approaches,
depending on the intended use. We will begin with the basic uncrating and initial unit set-up and then
discuss the various set-up options which are available to you for other uses.
Your H.E.R.O. airless sprayer has been full factory tested prior to shipment.
However we recommend that the following safety and set-up procedures be
followed.
1. Remove unit from shipping carton. Inspect exterior of unit for any signs of freight damage. If any
parts are found to be broken or damaged, immediately contact the carrier and arrange for an
inspection of the concealed damage. Claims for freight damage must be made by the
CONSIGNEE and not by the shipper. The carrier accepts full responsibility for the safe delivery of
merchandise upon pick- up from the shipper.
2. Attach intake siphon assembly (ref # 1) to intake hose barb (ref # 6). Tighten hose clamp ( ref # 5 )
securely.
Step 2
Step 3 & 4

UNIT SET-UP
The 4500D is supplied with one (1) gun mounting bracket, horizontal arm.( ref # 167 ) and one
vertical arm ( ref # 168 ). It may be mounted on either the right or left side of unit, based on your
personnel preference. An optional second gun mounting kit ( Part # 4-06-440-485 ) is available for
those who wish to spray dual lines, or a combination single strip and curb application. More
instructions on pages 13-19.
When operating only one gun, as shipped, a minimum of 50’ of 1/4 airless paint hose is require d.
6. Coil the majority of the paint hose around the units’ hose wrap. Leave sufficient length to reach gun
mounting bracket at it’s furthest possible reach ( 6-8 feet ).
NOTE: Hose should be coiled loosely to avoid kinks
7. Loosen wing nut ( Ref # 164 hidden in this diagram ) This will loosen the gun holding tab ( Ref #
162 ) and provide clearance for the gun handle to be inserted.
8. Temporarily remove gun trigger guard from gun swivel. Move to the side to allow gun installation.
9. Turn gun perpendicular to gun mount. Insert gun swivel / hose connection into the gun mount.
10. Rotate gun until parallel with bracket. Ensure trigger activation screw ( Ref # 154 ) is under the
trigger.
11. Slide gun handle back until the notch found on the gun body, contacts the mounting bracket.
Tighten wing nut ( Ref # 164 hidden in this diagram ) to secure gun in bracket.
12. Reposition trigger guard on gun.
13. Check operation of the remote trigger lever ( Ref # 148 ) to ensure smooth operation of gun trigger.
NOTE: The remote trigger activation cable is factory set and should not require additional

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 they are tight.
Vibrations during transport could cause items to loosen.
CHECK to ensure that there is a spray tip in the gun, and that the tip is the correct size for the
coating you are to spray. ( There are various tips available, for each type of coating or configuration.
See " Airless Spray Tip " on pages 21 – 22 , 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.
READ THIS MANUAL THOROUGHLY.
READ THE HONDA ENGINE MANUAL SUPPLIED WITH THE UNIT. FOLLOW ALL
THEIR RECOMMENDED PROCEDURES FOR “START-UP” AND OPERATION
With all set-up instructions complete you can move on to the start-up and testing of unit operation.
Before doing so, we want to take this chance to encourage you to experiment with your new
equipment. If this is your first H.E.R.O. Linestriper, we recommend that water be used as a test
material. Take the opportunity to experiment with the equipment and become familiar with the
controls and the various gun set- up options ( see pages 17 – 18 ).
Operation of a linestriper requires many new skills and is quite different than that of a regular airless
paint sprayer. To be proficient, practice is required.
Painting straight lines is not that difficult, as the unit will roll in a straight line with little or no
assistance. NOTE: Like an automobile, wheel alignment is critical. The front swivel caster can be
knocked out of alignment, making a straight line extremely difficult.
Practice your timing, - starting and stopping the spray flow to create dotted lines. Practice your
technique for creating circles and curves. These may be your most difficult procedures. Practice all the
situations you will encounter. Remember the final outcome of your job effects your reputation. An
ineffective or poorly done job, may impact your ability to get repeat or referral business.
Once you are comfortable and feel confident in your abilities and the operation of the unit, it is safe to
begin using paint.
To start the unit and practice with water, follow the instructions on page 10, omitting the change to
paint. Good Luck and Good Striping!

Prime Valve
1. Place intake siphon assembly into a clean 5 gallon pail.
2. Install strainer bag (accessory item 5GAL SB) in pail and secure with large
rubber band.
NOTE; Strainer bag must remain 4 inches from the bottom of pail
3. Trigger gun to release any pressure in the unit. Use extreme caution to ensure
that the gun is not directed towards anyone or any object which may be
damaged.
NOTE; Unit may contain storage solution.
4. To remove storage solution, add one gallon of thinner, compatible with the
type of paint to be used, to the siphon pail.
5. Turn pressure control knob (ref # 75) counter clockwise to lowest pressure
setting.
6. Start engine. See Honda owner’s manual for correct procedures.
7. Turn prime valve handle (ref # 46) counter clockwise until fully open. Allow
thinner to circulate back into the siphon pail for a few minutes. Then turn the
prime valve handle clockwise to close the valve ( close tightly ), and direct the
flow to the paint hose and gun. Leave the pressure setting low.
8. Trigger gun into a waste container.
9. Remove rinse / prime fluid and pour paint through strainer bag into siphon
pail.
10. Repeat step 7, until paint flows freely.
NOTE; Never turn prime valve back to "prime" position when the unit is
under pressure.
NOTE: The thicker paint will require a longer time to complete the initial
prime circulation through the prime valve. Leave the valve in the prime
position to ensure the complete removal of all air and pre-prime fluid. Several
minutes may be required, particularly with thicker viscosity products.
11. Spray a test pattern. Begin by spraying a test pattern onto old newspaper or
other scrap material. Increase the pressure, slowly at first, by turning the
pressure control knob clockwise. Continue increasing the pressure until the
spray pattern is uniformed from top to bottom, with no heavy areas. Secure
pressure control setting, by turning the silver lock ring (ref # 77) counter
clockwise until snugly against the face of the pressure control knob. If heavy
areas are still visible at maximum pressure setting, thin the paint with the
correct thinner, according to the paint manufacturer's recommendations.
Paint Straining
It is recommended that all products entering the sprayer, be pre-strained to remove any large
particles and contaminants, BEFORE they are drawn into the sprayer. The strainer bag should
remain in place throughout the painting operation. This will prevent foreign matter from falling into
the bucket and contaminating the previously strained paint. The gun filter should not be relied upon
to do all the paint filtration. Any dirt, grime or other undesirable particles which reach the gun
filter have passed through the entire paint pump and have possibly created unnecessary damage
and inconvenience. Always strain the paint before siphoning.

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 in step 7 & 9. Switch prime
hose from paint pail to waste pail when cleaning fluid emerges.
7. Place siphon assembly in container of correct thinner, for the spray product
being used, and prime the pump as shown in step 6, of "Spraying". *See
special notes from step 6. Allow thinner to circulate back into the container for
a few minutes to flush the prime valve.
8. Close prime valve, turning counter-clockwise.
9. Trigger gun into paint container until thinner comes through. *See special
notes from step 6. Release gun trigger when cleaning fluid emerges. 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.
10. Lift siphon assembly out of cleaning fluid and allow pump to run dry.
11. Insert tip into gun. Turn to “Cleaning Position”. Repeat procedure using 1-5
gallons of H.E.R.O. Equipment Wonder Wash solution. Unit must not be

pressure.
13. Clean and rinse gun handle filter in correct thinner, and return to gun.
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 store the unit with water in pump. DO NOT
allow storage solution to freeze in pump. NOTE: 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 solution only

LINE STRIPING SUGGESTIONS
To ensure a sharp, crisp line, always use newer condition spray tips. Spray tips are available
specifically designed for the purpose of line striping. However, our experience has shown that most
standard spray tips will provide excellent results, without the need to use the specialized striping tips.
Let your standards of excellence be your guide.
The painted line width can be adjusted by changing the spray tip, or by raising or lower the gun/tip in
relationship to the spray surface ( ground ). For example: A tip which has a 4” spray pattern when 6”
from the surface ( ground ) will increase in width ( while loosing its crisp edge ) when raised to a
height greater than 6 inches.
Coverage ( Paint thickness ) can be adjusted by changing the tip’s orifice size or by adjusting the speed
at which the unit is moved. To increase coverage, either use a larger orifice tip or move the unit more
slowly. To decrease coverage, use a smaller orifice tip or move more quickly. Your experience will
help you determine which orifice size is best for you and the product you are using.
When selecting tips, take into account;
þ Product viscosity ( consult product manufacturer and product label for tip recommendations )
þ Your own personal cadence or walking speed. ( If you like to walk slowly, do not allow the spray
application to over whelm you. If you walk quickly, ensure the tip orifice is providing sufficient
flow to create the desired coverage )
þ Desired application thickness.
CAUTION: Always engage the gun’s trigger locking mechanism, before adjusting the gun
position or changing tips. Failure to do so could result in serious injury, as the gun may be
triggered accidentally or unpredictably.
The 4500D framework for gun location is fully adjustable to allow the gun or guns to be positioned in
any location as required by the specific line stripping application or personal preference.
When factory shipped, the gun trigger is located on the right handle, while the caster release trigger is
located on the left. The gun mount and extension arm have been placed on the right hand side of the
unit. These items may be switched to the opposite sides if desired ( lefties etc. ). When operating in
extremely close quarters, it may be required to move the gun controls from the right side to the left side
regardless of your personal preference. All these options are available to you.
One of the important features of the 4500D is the single, pivoting or swiveling front caster ( ref # 133 ).
The unit has been factory tested to ensure the unit will track in a straight line with virtually not
assistance required. Shipping, handling and daily use may throw the caster out of alignment. When this
occurs a great deal of control will be required to keep the unit on a straight line. Re-alignment of the
front caster will be needed to correct this. To utilize the front caster, activate the release switch ( ref #
133 ) on the left handle as you begin to enter the arc or curved pattern. Keep the switch activated
through the entire curved pattern and release as you exit the pattern.
Proper gun placement is required to ensure the rear wheels do not roll over the freshly painted line. See
instructions to follow.

LINE STRIPING SUGGESTIONS
The following diagrams and instructions outline the various ways in which the 4500D can be
configured and used. These are meant as a guide to assist you in becoming familiar with the unit.
GUN POSITION AND SET-UP
STRAIGHT LINES – Figure 1, shown below, is the configuration which is most commonly used in
parking lot layouts. In this configuration, the gun is extended to the front of the unit, making it possible
to approach a curb at 90º and paint flush to the curb. Gun control arm and mount may be placed on
either the right or left side of the unit, based on personal preference or to work around obstacles in your
path.
NOTE: This set-up is not suitable for circles or curves. With the gun in this position, the rear wheels
will run over freshly painted curves or circles.

DUAL STRAIGHT LINES – Figure 2, shown below, is a duplication of figure 1, using two guns for
a dual line. This configuration can be used any where a dual line is needed. Individual gun activation
controls allow for dual single or broken lines. Used primarily for roadway lines. Placing the guns close
together will allow the combination of spray patterns when an extra wide single line is needed.
NOTE: Optional second gun controller kit ( 4-06-440-485 ) and mounting connectors required. See
page 13 for specifications.

SPRAY TIP SELECTION
Although the 4500D has been designed with line striping as it’s primary function, it can also function
as a regular airless paint sprayer.
Airless spray tips are a key component to the successful operation of an airless system. They define the
spray pattern, control the flow and ultimately tell the pump how hard it must work. A proper
understanding of airless tip is critical to the success or failure of any airless application and can help
you avoid many of the profit thieves you face daily.
Airless Spray Tip Characteristics – It is important to remember that the orifice size, in conjunction with
the fan width size determines the spray characteristics of the tip.
EXAMPLES: The larger the orifice with the same fan width, the greater the volume of paint applied to
the same area.

Conversely, the larger the fan width with the same orifice means the same amount of material is being
applied over a greater area. The result is less volume of paint per square inch.

WHAT CAUSES TIP WEAR ? - The velocity with which material moves through the orifice will
cause wear due to abrasion. This wear will effect the flow rate ( increases ) and the quality of the spray
pattern. Many factors will affect the wear of the tip.
A. The viscosity and quality of the material being sprayed.
B. The amount of pressure being used.
C. Cleaning the equipment with the tip still in the spray gun.
D. Wrong filter mesh size for material being used.
HOW TO DETECT TIP WEAR – The easiest way to detect tip wear is by the pattern. The pattern
width ( Fan ) will narrow and lose its feathered edge as the tip wears. When the pump can no longer
keep up with the tip size “tails” will occur from the pressure drop.
HOW TO IMPROVE TIP LIFE – These procedures can improve tip life.
A. Always use filters in your airless gun and pump
B. Use the minimum amount of pressure to achieve proper atomization.
C. Remove spray tip before cleaning equipment.
D. Strain all paint.
WHY SPEND SO MUCH TIME ON TIP INFORMATION ? - The largest percentage of pump
complaints can be traced back to blown tips or the wrong size tip used for the material being sprayed.

UNDERSTANDING THE PUMP OPERATION
Hydraulic Energy Regulated Output (H.E.R.O.) is more than just our name, it is the bases for the operation of
the pump. It is the regulation or control, of hydraulic energy, which allows the equipment to build and then
deliver or have an output of pressure. Once you have a basic understanding of the operation of the equipment
and the effect created in one area and how it will effect operation in another area, you will be better able to
diagnose and make repairs.
All H.E.R.O. hydrapulse membrane pumps are made up of two (2) distinct pumps. The first, and most
important pump is the hydraulic pump. The hydraulic system is made up of two valves, the hydraulic intake
valve (ref # 66) and the hydraulic outgo valve, known as the hydraulic pressure control valve (ref # 74). The
second pump is known as the paint or material pump. The paint system is made up of two basic valves, the
paint intake valve assembly (ref # 11-18), paint outgo valve, (ref # 26). A third valve, known as a bleed valve
(ref # 37) is used during the priming procedure, (see "setting up to spray"). For correct operation, all five
valves must be in good working condition. For this manual we will refer to the two systems as "hydraulic"
and "paint".
At the center of these two pumps is the hydrapulse membrane. The hydrapulse membrane is a flexible nylon
disc which transfers the energy (pressure) created by the hydraulic pump, to create energy (pressure) in the
paint pump. The function of the hydrapulse membrane is to create a barrier between the hydraulic oil and the
spray material and transfer the energy created.
To fully understand and trouble shoot a H.E.R.O. pump, always keep in mind that "for every action, there is
an opposite or corresponding re-action". For every action of the hydraulic intake valve (ref # 66), there is an
opposite re-action of the hydraulic outgo valve (ref # 74). At the same time there are corresponding re-actions
taking place within the paint pump. This means that as the hydraulic intake valve is opening, so is the
corresponding paint intake valve, and while the hydraulic outgo valve is closing, so is the corresponding paint
outgo valve. The operation and function of each valve is discussed at the end of this section.
For correct operation to begin, the hydraulic system must be fully primed and all air must be removed
( see "purging" page 28 ). Operation begins with piston in the backward position (fig. 2). At this point the
hydraulic intake is open, while the hydraulic outgo valve is closed. The corresponding paint valves are in
similar positions.
As the piston moves forward, it pushes hydraulic oil forward. This movement of oil causes the hydraulic
intake valve to close and the hydrapulse membrane to move forward (fig. # 1). The hydraulic outgo valve will
remain closed until sufficient pressure is created to cause it to open. While the hydraulic valves are operating a
corresponding re-action is taking place in the paint valves. The forward movement of the hydrapulse
membrane pushes the paint, causing the paint intake valve, (ref # 11-18) to close. The trapped paint requires a
means of release, so it forces the outgo valve, (ref # 26), to open and paint flows to the gun.
Fig. 2
Fig. 1
H.E.R.O. Industries
23
4500D Owners’ Manual
UNDERSTANDING THE PUMP OPERATION
The backward movement of the piston, creates a vacuum in the hydraulic system. This causes the hydraulic
outgo valve to close and the hydraulic intake valve to open (fig. 1). Opening of the hydraulic intake valve
allows a new supply of hydraulic oil to enter the system, replacing the oil which was used on the forward
stroke. Once again a corresponding re-action is taking place in the paint pump. The hydrapulse membrane is
being pulled backward by the hydrapulse membrane spring, (ref # 56). The backward hydrapulse membrane
movement causes a vacuum in the paint pump. This vacuum causes the intake valve to open, allowing a new
supply of paint to enter. The corresponding paint outgo valve is drawn closed by the vacuum created by the
hydrapulse membrane.
These operations are repeated at a rate of 750 times a minute. These continuously repeated actions draw paint
into the pump, pressurize it, and then deliver it to the gun. The failure, of any one valve, to operate correctly
will effect the overall equipment performance. Each of the five valves mentioned earlier, have an important
function and will effect the overall performance of the unit if not performing correctly.
HYDRAULIC INTAKE VALVE ( REF # 66, PART # 4-30)
The hydraulic intake valve, is a small vacuum valve which controls the hydraulic oil entering the hydraulic
pump/cylinder area. Once the oil has past through the valve it is prevented from returning. The valve is
commonly called a “one way check valve”. Valve failure will result in the hydraulic pump being unable to
build pressure, and the hydrapulse membrane will stop moving. Spray pressure will cease.
HYDRAULIC OUTGO VALVE ( REF # 74, PART # 4-27C)
The hydraulic outgo valve, better known as the "pressure control valve", is used to control the units operating
pressure. The valve is fully adjustable from 0 psi. to 3000 psi. By turning the pressure control valve knob (ref
# 75) clockwise the pressure is increased. The hydraulic pump continues to build at all times and must have a
means of releasing this pressure. Pressure applied to the P.C. ball, (ref # 88) will keep it lodged in the P.C. seat
(ref # 87) until the internal hydraulic oil pressure is sufficient to cause it to open. The point at which the oil is
released is equal to the level set by the control knob. As components within the pressure control valve wear,
the valve looses its ability to maintain or reach the required pressures (see "low static pressure").
PAINT INTAKE VALVE ASSEMBLY (REF# 11-18)
The paint intake valve is made up of eleven items, endcap (ref # 11), washer (ref # 12), seat (ref # 13) intake
ball (ref # 14), spring (ref # 15), o-ring (ref # 16), ball guide (ref # 17), and ball stop (ref # 18). The intake
valve controls the incoming flow of spray materials and is responsible for keeping them from returning to the
source. The ball must be able to create a complete seal on the seat, otherwise pressure will be lost. A worn
intake valve will permit correct static pressure, but supply lower spray pressure. A worn intake ball will
become smaller in diameter and loose its ability to seal at the seat. A worn seat will develop a large step in the
area where contact with the ball is made. This can cause the intake ball to distort in shape making the ball egg
shaped. If the valve assembly becomes warm to the touch, this may be a sign of a loose or worn seat caused
by wear or improper compression caused by a worn intake washer (ref # 12). The intake washer (ref # 12),
acts as a compression washer insuring the seat (ref # 13) remains pressed into the endcap (ref # 11). The seat
must remain firmly pressed into the endcap at all times, through the correct assembly of parts listed, and the
correct bolt torque. Replace the intake washer (ref # 12) each time the endcap is removed. See page 32 for
details.
H.E.R.O. Industries

4500D Owners’ Manual
UNDERSTANDING THE PUMP OPERATION
PAINT OUTGO VALVE ( REF # 26, PART # 4-611C )
The paint outgo valve monitors and controls the flow of spray materials as it leaves the sprayer. It also works
together with the paint intake valve, to build paint pressure as specified by the setting made by the hydraulic
outgo valve (pressure control valve). A worn outgo valve will result in pulsation in the spray material and
cause the paint hose to jump and vibrate vigorously.
BLEED VALVE ( REF # 36, PART # 4-606 )
The bleed valve is used at the beginning and end of the spray operation (see "setting up to spray"). The
function of the bleed valve is to assist in removing air from the paint pump when beginning to spray. It is
necessary to remove all air from the paint pump so that the spray material can replace it. The pump will
function without the bleed valve, however, the initial priming procedure would require considerably longer to
complete. During the priming procedure the hydrapulse membrane is exposed to its greatest amount of stress.
Use of the bleed valve and a lightweight thinner, which is compatible with the intended spray material, will
reduce hydrapulse membrane stress and reduce priming time. The bleed valve will also allow you to remove
any unused paint left in the pump and hose at the completion of a job. When the bleed valve is open the
material is pumped through the paint intake and outgo and back to the source by way of the bleed valve.
When closed, no material should be escaping from the bleed valve return hose (ref # 51). If material escapes
through the bleed valve return hose, when the valve is closed, spray pressure at the gun will be reduced.
The solution to almost all problems can usually be found in the paint side valves. However,
before performing any repair or looking further, the following are things which can cause an
apparent sprayer failure, without any mechanical problem. ALWAYS check these items
before preceding.

PRESSURE TEST
To verify the operation of an airless sprayer, use of pressure gauge is required. A pressure gauge (min. 3000
psi) installed at the gun, using a new .021 tip, and not less than 50 feet of H.E.R.O. airless spray hose is
needed. If you do not have access to these items, your local H.E.R.O. authorized service center will be able to
perform this test. Your model 4500D is manufactured to perform at;
2650 psi -- Static pressure, with lock ring (ref # 77) on pressure control valve (ref # 74).
1950 psi -- Pressure drop, when gun trigger is squeezed.
2250 psi -- Spraying pressure, after recovery time.
If your unit is unable to perform to the above pressure levels consult the troubleshooting guide for the required
repair procedure.
HYDRAPULSE MEMBRANE TEST
If your unit is disabled and you are unable to perform a pressure test, use the following procedures for
determining the area to repair. This test will divide the two halves of the equipment (hydraulic from paint) and
make identification of your solution easier to obtain. This test is commonly referred to as the "Hydrapulse
membrane Test"
The solution to almost all problems can be found in the paint side valves, due to the increased wear from
contact with the abrasive paint/spray materials. Intake valve (ref # 11-18), Outgo valve (ref #26), and Bleed
valve (ref # 36) make up the three paint valves. Refer to pages where exploded views of these valves are
shown. To eliminate the hydraulic side of the pump (piston side of hydrapulse membrane) as a source of
problems;
1. Remove the intake valve end cap (ref # 11) by removing the
four cap screws (ref # 9 ). The intake valve assembly, (ref #
11-18), will generally come off as an entire assembly,
requiring no further dismantling. If the ball guide (ref # 17)
and ball stop (ref # 18), remain in the paint head, they can
be pried free with a screwdriver.
2. Start unit.
3. Increase the pressure by turning the pressure control knob
(ref # 75) clockwise to full pressure.
4. Put pressure on the center of the exposed hydrapulse
membrane with the handle of a screwdriver or other blunt
object.
5. NOTE: The hydrapulse membrane is located between the
paint head (ref # 21) and the hydraulic head (ref # 59)
6. If you are UNABLE to stop or alter the hydrapulse
membrane's movement, then the hydraulic side is operating
properly. The problem is located in the “Paint” pump. See
troubleshooting guide for additional information.

17 Place flat washer (one side has a contoured face) into groove "C", then place o-ring in front of flat washer,
so that it fits into the contoured face of the flat washer.
18 Place one cup washer into groove "B", with open face of cup washer facing the end of piston. (towards
hydraulic oil when installed)
19 19. Place second cup washer into groove "A".
NOTE: Always work from the front of the piston back so that you are always moving the cup washers
over filled grooves. This avoids damage that can occur to the cup washers if they have to be dug out of
one groove and moved to another. Avoid over stretching.
NOTE: A small, dental like tool, may be used to assist in moving cup washers.
20 Apply grease to seals before installing in cylinder, (ref # 61).
21 Slide pump assembly into side frames and guide piston into cylinder.
NOTE: Use care not to push the piston too far into cylinder. If piston rings slide in too far they will pass
through cylinder into the hydraulic cavity. Complete dismantling of piston will be required to remove.
The piston can not be pulled back if the seals have gone through cylinder.
22 Reattach crossblock bolts, as removed in step 2. Torque bolts to 30 foot pounds.
23 Reconnect hydraulic lines, as removed in step 1.
24 Add new hydraulic oil to hydraulic tank, using only genuine H.E.R.O. LVO hydraulic oil.
25 Once the repairs have been completed, the hydraulic oil will require purging to remove the trapped air.
See "PURGING" instructions on page 28.
