Check the Specications section of this manual to determine correct carrier size, hydraulic ow and pressure
requirements.
If hydraulic pressure, hydraulic back-pressure, hydraulic
ow or excavator weight class are exceeded, the tool
warranty is void.
EXISTING EQUIPMENT HYDRAULICS VS.
APPLICATION ATTACHING KITS
Using existing equipment hydraulic auxiliary systems
for operating hydraulic tools could cause problems for
the hydraulic tool and the hydraulic system if not set up
properly. Simply plugging into the hydraulic system with-
out conrming pressure and ow to the hydraulic tool is
not a good practice. Spare spool valves, dipper circuits,
etc., are just a few examples of easily accessible hydraulic circuits which could prove to cause problems for
hydraulic tool usage.
Stanley Hydraulic Tools has for many years developed
ATTACHING KITS for adapting to existing hydraulic systems of many popular carriers.
If your equipment does not contain an attaching kit, ask
your Stanley dealer for information, installation, and
pricing on a kit which matches your equipment needs.
PRE-OPERATION PROCEDURES
NITROGEN CHARGE
The breaker has been properly charged with nitrogen at
the factory and is ready to use.
TOOL BIT LUBRICATION
Grease the top 250 mm / 10 in. of the breaker tool bit before installing. During operation, the tool can be greased
through the grease tting. Grease is required.
Make sure the tool bit is against the piston by placing the
tool bit against the ground and then putting down pressure on the breaker. See the illustrations below.
TEST THE HYDRAULIC SYSTEM
1. Have your Stanley dealer test the carrier hydraulic
system to make sure the system is operating at the
manufacturers specied capacity and pressure ratings.
2. Be sure the uid in the hydraulic system is clean.
3. Check the hydraulic lter. Replace the lter if dirty or
deteriorated.
4. Have your Stanley dealer test the circuit to which
the breaker will be connected to make sure that the
circuit is supplying the specied ow and pressure
rating for the breaker. See the Specications section
of this manual.

OPERATION
WARNING
Greasing the tool bit without down pressure on the
breaker results in grease lling the space between
the piston and the tool bit. When the breaker is next
activated, the piston will strike the grease at a speed
which will pressurize the grease resulting in seal and
grease zerk failure.

LOW TEMPERATURE WARM-UP
PROCEDURE
1. After starting the carrier, warm-up the hydraulic system at engine idle until hydraulic lines are warm to
the touch.
2. With the carrier at idle and the breaker suspended
in the air or with minimal down pressure, turn on the
breaker to gradually warm up its internal components.
3. When the hydraulic system and breaker are warm,
proceed with operation.
LONG TERM STORAGE
1. Remove the tool bit, clean the tool stop and the lower bushing. Thoroughly coat the surfaces of the tool
stop and the lower bushing with grease.
2. If hoses are attached to the breaker, install plugs
on the hose ends. If hoses are removed from the
breaker, install plugs on the hose ends and install
plugs in the breaker IN and OUT ports.
3. Store the breaker in a vertical position. Do not store
the breaker horizontally for extended periods.

OPERATION
OPERATING THE BREAKER
PREPARATION FOR USE
Read the section in this manual titled Pre-Operation Procedures before operating a breaker. Failure to follow the
preparation instructions can result in severe damage to
the breaker and carrier and void the warranties of both.
POSITIONING THE CARRIER
BACKHOES
With the breaker tool in place on the material to be
worked, position the backhoe so the boom is halfway up
(45°) and the dipper holds the breaker almost vertical.
Lower the loader bucket until the weight is off the front
tires.
EXCAVATORS
With the breaker tool in place on the material to be
worked, position the excavator so the dipper is at approximately 45° and the breaker is almost vertical. The
tracks of the excavator should be in line with the boom
and the breaker.
POSITIONING THE BREAKER TOOL ON
THE WORK MATERIAL
Position the tool bit near the edge of the work material,
not in the center or far from the edge. Position the tool 6
– 18 inches (depending on the material) from the edge.
Breaking off smaller pieces of rock or concrete usually
accomplishes more than trying to break larger pieces.
Apply down force to the boom/dipper until the rear of the
backhoe is raised off the ground. Rear tires and stabilizers should be off the ground so the total rear weight of
the backhoe is on the breaker tool. The breaker is more
efcient when adequate down force is applied.
On at material or rock, the breaker should be vertical
or “curled” back slightly to direct the impact force downward and toward the backhoe. This directs the force
back toward the edge of the work material. If the tool
is positioned in the center of the work, or too far from
the edge, the energy will be absorbed into the material
without cracking it. Do not run the breaker longer than
MB05 User Manual ◄ 11
Scoring with the breaker
Do not break continuously
in one place.
CAUTION
OPERATION
15 – 20 seconds. If breakout does not occur within this
time, move the breaker to another position.
On at material such as concrete runways, starting to
break in the middle of the material may cause vibrations
to be transmitted throughout the breaker and excavator
because the material has no place to break to. Always
try to start at a point which will permit the material to
break out.
MAINTAIN DOWN PRESSURE
Maintaining hard contact with the surface of the material
to be broken in addition to maintaining adequate “down
force” is very important. Always keep “down pressure”
or “down force” on the point of the breaker by lifting the
wheels, tracks, or stabilizers slightly above the ground.
This method takes the “slack” out of the bracket and
boom pivots, and reduces the impact on the pivots in
the boom.
The operator needs to be constantly aware of the amount
of down pressure being applied and be able to adjust it
if necessary. Not enough down pressure results in low
production and accelerates wear and tear on the equipment. Too much down pressure may cause the breaker
housing to violently crash into the broken material when
“break-through” occurs.
In any breaking job, the operator should make every effort to “follow” the breaker with “down pressure” as the
machine breaks farther into the material. The breaker
should be stopped as soon as “break-through” occurs or
if it is apparent that good solid blows are not occurring.
BREAKING
The operator should note the sound of the blow when
the breaker is running. With experience, the operator will
be able to tell the difference between a good solid blow
and a hollow sounding blow. A hollow blow means that
solid blows are not occurring and breaker should be repositioned.
Continuous tool penetration usually does not do much
good. If the material does not break with 3 – 6 inches of
tool penetration, it usually won’t break with full penetration. The time used for additional penetration could be
better used to strike blows in another place.
Many materials do not respond well to continued hammering in one place. The breaker tool should be repositioned on the work each time the tool penetrates but
does not crack the material.
Continuous penetration in the same area for lengthy
periods will create excessive temperatures at the tip
of the tool bit resulting in loss of temper (hardness)
of the bit, mushrooming of the tip of the bit and may
lead to failure of the bit.
Use a “scoring” method of breaking when cracking
the material becomes difcult. This technique involves
striking the rock or concrete at several places along a
line where you want the crack to occur. Most materials
break sooner when struck several places along a line
than when struck repeatedly in one location. On each
line, the breaker tool should be continually repositioned.
Practice determines the best length of time to stay in
one spot. (15 – 20 seconds) and how far to move the
breaker tool.
12 ► MB05 User Manual
Breaker tool bit binding
CAUTION
OPERATION
Breaker tool binding can cause erratic breaker operation and premature wear on the tool shank. Breaker tool
binding is caused by failure to direct the down force in
the direction of the tool bit.
Do not pry with bit and breaker. The tool bit may
break causing injury.
Excessive side force cocks the tool in its bore, prevents
proper movement and causes premature tool shank
and bushing wear. Since the breaker tool bit must be
pushed up into the breaker to operate, a binding tool
prevents the breaker from operating correctly. Binding
also causes the tool bit and tool bushings to seize and
often results in breakage of one or more breaker components.
Always direct the down pressure force in a line toward
the point of tool contact with the work.
Moving rocks with the tool bit is another method of binding the tool bit. This practice should be avoided as it may
cause tool bit failure.
Rebar reinforced concrete introduces the problem of
concrete chunks being held together by the rebar after
the concrete has been broken. The best approach to this
problem is to use a chisel point tool which permits cutting the rebar with the breaker. Another method is to periodically cut the rebar with an oxy-acetylene torch
BLANK FIRING
To understand “Blank Firing”, the operator needs to be
aware that the tool bit is able to drop down in the lower
body cavity, far enough so that the piston cannot strike it,
when the tool bit is not in contact with the work surface.
“Blank Firing” occurs whenever the breaker is operating
and the piston is not able to strike the tool bit solidly or
not strike the tool bit at all. “Blank Firing” accelerates
wear and tear on breaker and carrier components and
may result in failure of one or more components. Excessive “Blank Firing” may be considered equipment abuse
and may result in voiding warranties.
Break-through or difcult surface contact results in
“Blank Firing” when the material being broken fractures
and the tool bit is no longer in “hard contact” with the
material but is still pushed high enough in the lower body
cavity so that the piston can strike it. In this position, the
piston strikes the tool bit and the tool bit, in turn, is driven
against the retaining pins because it is not in sufcient
contact with the material to be broken. The energy is absorbed by the retaining pins, other breaker components,
and the carrier boom components. “Blank Firing” of this
type can be experienced in trench work where obtain-
ing striking contact with the work surface is difcult or
the wrong tool bit is used, or in at rock work where the
operator fails to stop operation of the breaker when slippage, fracturing or material break-through occurs.
“Blank Firing” as a result of operator error occurs when
the tool bit is not in contact with the work surface to be
broken and is allowed to drop down in the lower body
cavity so that the piston is not able to strike it. Instead,
the downward movement of the piston will be stopped
by an internal oil cushion located at the bottom of the
piston’s stroke and the energy of the piston will be absorbed by breaker components and excavator boom
components. “Blank Firing” of this type can be experienced when the operator fails to stop operation of the
breaker when the material fractures or material breakthrough occurs, or during re-positioning of the breaker.
While “Blank Firing” cannot always be avoided, it can be
kept to a minimum by avoiding the above conditions as
much as possible.
MB05 User Manual ◄ 13
Do not use und erwater without supplying air to b reaker.
CAUTION
OPERATION
UNDERWATER USAGE
Underwater usage of the breaker will cause damage
to internal components. Even if the breaker is partially
submerged, water is introduced to an area between the
tool bit and piston. On the piston down cycle, the water
becomes compressed and damages adjacent components.
DO NOT USE UNDERWATER
GREASE THE BIT
Grease should be applied to the upper end of the breaker tool bit each time it is installed. Thereafter, the tool
should be greased at the tting to reduce wear in the
lower body and bushings of the tool. See Greasing The
Tool Bit in the sections titled Pre-Operation Procedures.
No part of the breaker may be submerged in water.
Underwater usage of the breaker will cause
internal damage to the breaker. Consult Stanley for
modications and specic warranty coverage if you
have an underwater requirement.

MAINTENANCE
DAILY MAINTENANCE CHECKS
Check for loose or missing fasteners. Tighten or replace
as needed.
Inspect tool retaining pins and pockets for wear.
Check for hydraulic leaks at all ttings and hoses. Replace any defective hoses.
Apply grease to the grease tting in the lower body each
morning. Grease as needed throughout the work day.
TOOL STOP AND LOWER BUSHING
Inspect the tool stop and lower bushing for excessive
galling and metal pickup on the tool bit. Also check for
cracks. If cracks are present, the part must be replaced.
The extent of wear of the tool stop and lower bushings
and the tool bit can be checked by moving a NEW tool
bit back and forth and measuring the gap between the
tool bit and the lower bushing. If the gap is more than
.250 in./6 mm, the upper bushing, lower bushing and
tool bit should be replaced. A gap in excess of .250 in./6
mm will cause damage to the piston. Do not just replace
the tool bit or the lower bushing individually as this will
result in premature wear of the replaced component. It is
recommended to replace ALL worn components.

CHARGING THE ACCUMULATOR
The tools required to charge the breaker accumulators
are the 505232 charge hose assy and the 28257 accumulator tester which are used with other Stanley model
breakers. When charging the accumulators, make sure
the tools and charge valves are clean. Dirt can contaminate the charge valves and cause leakage.
1. Remove the protective plug from the accumulator
charge valve. NOTE: There is one accumulator on
this breaker; the upper accumulator.
2. Hold the chuck end of the tester and turn the gauge
fully counter clockwise to ensure the plunger inside
the chuck is completely retracted.
3. Screw the tester into the breaker charge valve by
turning the chuck. Do not use the gauge for turning as this will advance the plunger in the chuck.
Tighten the chuck lightly against the breaker charge
valve.
4. Turn the gauge clockwise to advance the plunger
until a pressure is indicated on the gauge. Do not
overtighten.
5. If the pressure is correct, unscrew the gauge to retract the plunger. Then, loosen and remove the tester from the charge valve. If the pressure is not correct, proceed to Step number 6.
NOTE:
When disengaging the tester a "POP" of nitrogen is
normal.
6. Connect the charge hose assembly to the charging valve on the tester. Make sure the valve on the
charge hose assembly is closed. Open the valve on
the nitrogen bottle.
7. Very slowly open the valve on the charge hose assembly and slowly meter the nitrogen into the breaker charge valve until the tester reads the correct
charge pressure (200 psi).
8. When the correct pressure is obtained, close the
valve on the charge hose assembly and on the nitrogen bottle. Unscrew the gauge to retract the plunger. Loosen and remove the tester from the charge
valve. Before replacing the protective plug, inspect
the plug o-ring. If damaged or deformed, replace the
plug. Apply Loctite™ 242 to plug and cap.

LOWER BUSHING
To increase the life of the lower bushing, remove the bushing after normal wear has developed and rotate the bushing 90° and lock into the second slot. Normal wear on the bushing
is usually found from front to back, by rotating the bushing 90° will add additional life to the
bushing. In addition to rotating the bushing, it is also symmetrical and can be ipped end
to end and again rotated 90° resulting in even longer life.
TOOL STOP
To increase the life of the tool stop, remove the tool stop after normal wear has developed
and rotate the tool stop 90° and lock into the second slot. Note: the tool stop is not sym-
metrical and can not be ipped from end to end.

PROPER CARE OF TOOL BITS
Tool bits are made and heat treated to specication.
Tool bits, however well made, are wear parts, and are
used in the most destructive applications. Even when
the hydraulic breaker is used properly, and the operator
is an experienced one, a tool bit may become damaged.
When a tool bit has been damaged, it is useful to determine the cause immediately in order to prevent the
damage from occurring again.
All Stanley tool bits are machined and hardened for
maximum performance. Care must be taken to maintain
the tools original condition for optimum productivity and
life expectancy. It is not uncommon for an operator who
is unfamiliar with using a hammer to break a point. This
is part of the learning experience.
Listed below are several methods to determine tool failure and will quickly aid in warranty determination.
TOOL FAILURE NOT COVERED
UNDER WARRANTY
BLANK FIRING OR FREE RUNNING
This occurs when the tool is not in proper contact with
the work, thus causing the energy produced by the hammer to be concentrated on the tool retainer(s) and the
retainer slot(s) on the tool itself. Caution should be used
to prevent the hammer from sliding off slanted surfaces
or when breaking through thin material.
The illustration below is typical of the kind of breakage
that occurs from excessive blank ring.
METAL-TO-METAL CONTACT
Extreme caution should be used to avoid scratches or
gouges on the surface of the tool. These areas create a
stress concentration Metal-to-Metal Contact point, thus
weakening the tool.
Another form of metal-to-metal contact is galling, which
usually occurs from the lack of lubrication. Special care
should be taken to keep the tool shank lubricated every
two (2) to three (3) hours.
Steel failures that were caused by surface damage take
two main forms. The simplest form is caused by deep
scratches on working steel surface. The broken surface
has a shell pattern around the starting point of failure,
similar to the one in the fatigue failure. The other parts of
the broken surface are brittle. These failures work slowly
through the steel until it suddenly parts completely.
The second form of failure caused by surface damage
occurs when there are deep scratches on working steel
surface and there was also excessive bending stress.
The broken surface also shows the shell pattern, but the
other parts of the broken surface are brittle and usually
have a “lip” like that in a stress failure.
WORN-OUT FRONT BUSHING(S) OR
RETAINER PIN(S)
Worn-out front bushing(s) will cause the tool to become
misaligned inside the hammer. This misalignment will
cause uneven contact between the piston and tool, thus
causing stress to concentrate on one particular area of
the tool. This can also cause the tool to bind inside the
hammer. Call your dealer for acceptable wear allowances.
Worn-out retainer pin(s) will cause uneven loading on
the pin(s) themselves, causing failure of the tool or retainer pin(s). This will also cause excessive wear to the
front bushing(s).
MB05 User Manual ◄ 19
PROPER CARE OF TOOL BITS
In its most extreme forms, the combination of surface
damage and severe bending can quickly break even the
best working steels.
The illustrations below show examples of severe stress
breaks.
PRYING
This is the most common cause of tool failure. Even
when there is no surface damage, the stress from prying can easily break a working steel. This kind of failure
generally results from any type of side pressure such as
an incorrect breaking angle or from using the tool to reposition material. The tool should not be used as a pivot
point when repositioning the carrier. The power generated by the carrier will far exceed the strength of the tool.
CORROSION
Tools should be greased and stored out of the weather.
Corrosion tends to accelerate the fatigue fractures of the
tool.
MUSHROOMING
Driving the tool into a hard material for a long period of
time generates an intense heat, indicated by a blue tone
just above the point. This will soften the steel and cause
the point to fold over or mushroom the end of the tool.
Avoid hammering in one location for too long. If material
does not break after a short period (approximately 15 to
20 seconds), reposition the tool.
Similar failures can also occur when the steel is used
with extreme down pressure, and the steel repeatedly
slips off the work at an angle, or the material, itself
moves from under the working steel.
As the next illustration shows, fatigue failures take many
forms, but they all exhibit similar features. Generally, the
broken surface is brittle and has a “lip” like that in the
bending failure, even though, in some cases, the lip has
been broken.
If the overheated steel is suddenly cooled by being
dipped in standing water, for example, the metal will
harden and become brittle. These are some examples
of failure caused by temper changes occurring on the
job.

PROPER CARE OF TOOL BITS
TOOL FAILURE COVERED UNDER
WARRANTY
INTERNAL MATERIAL FLAW
This failure occurs when a foreign material is rolled into
the steel during the manufacturing process, causing an
imperfection in the internal material aw grain. The result is an inherent weakness in the tool shank and eventual breakage.
The fatigue failure is started by the defects within the tool
bit. The broken surface exhibits a shell pattern around
the starting point of failure, like that in the fatigue failure.
The other parts of the broken surface are brittle.
This is the only kind of tool bit failure that is always
covered under warranty.
• Failures in this area are usually the result
of blank ring, worn bushing(s), worn re-
tainer pin(s) or the lack of lubrication.
• Failures in this area are usually the result
of worn retainer pin(s) or blank ring.
• Failures in this area are usually the result
of prying, metal-to-metal contact or corrosion. Prying failures often exhibit a shelllike formation near the edge of the steel
diameter where the break began, and a
“tail” opposite that where the remaining
steel bent and tore.
• Failures in this area are usually the result
of heat build-up, mushrooming, or improper contact with the work.
As a rule, working steel failures can be diagnosed by
looking at the break itself, and at the place on the steel
where the break occurred. Discoloration, like “rainbow”
effects or blue bands, is the result of extreme heat.
Look for surface cracks, galling, or gouge marks. Breaks
that start as surface damage have a “sea shell” pattern,
with the damaged spot at the center. A large “sea shell”
indicates a slow growing break; a small one indicates
one compounded by side stress.
Stress failures start small, and spread into the center
of the steel. In a stress failure, the coarser the grain,
the greater the stress was, and the more rapid was the
failure.

PROPER CARE OF TOOL BITS
Stanley Breakers are available with several different
types of tool bits. The most common are the moil, chisel
and the blunt. Each of these working steels has its own
purpose as described below:
To obtain the maximum production from the breaker, it
is important to select the proper working steel. Consult
your Stanley representative for assistance in selecting
the proper working steel for your application.
MOIL
This is by far the most popular
working steel. It is a general
purpose point used to break
anything from concrete to hard
rock. Its pencil-type point is
used to fracture the material.
The tool is best where penetration speed is important.
CHISEL
This style of point is used generally used for trench work,
where a controlled break is required, and for rock breaking
on materials with a denite line
of cleavage. A chisel bit also
works well in softer concretes
where a moil might penetrate
quickly, but not cause a fracture line.
BLUNT
This at type of point is used to
break softer material such as
coal or shale. A moil or chisel
will tend to punch holes in this
type of material, where a at
blunt will shatter the material.
It is also useful when breaking irregularly shaped material
where its broad tip makes it
easier to position.

FLOW TEST PROCEDURES
The correct performance of this procedure will verify if
the auxiliary circuit of the carrier is adequate to properly
operate a Stanley attachment.
This procedure is generic in form. It is the end users
responsibility to ensure that this procedure will work with
his specic type of equipment.
If an adequate ow meter is not available contact your
Stanley Hydraulic Distributor for assistance.
TEST PROCEDURE
1. With the auxiliary circuit (or kit) completely installed
connect the ow meter between the tool inlet and
outlet hoses.
NOTE:
Always use the hoses that are supplied for the at-
tachment and make sure the machine hydraulic
oil is between 90 to 120 °F. This will assure correct
readings and adjustments.
2. With the machine setting at the mode that’s going to
be used to operate the attachment record the GPM
_____.
Locate the correct ow for the attachment in the
manual under the specication section. Adjust the
machine to the correct GPM.
NOTE:
If possible, always set the machine to the highest
GPM output mode. This will prevent the operator
from over owing the attachments.
3. Once the correct GPM ow is achieved fully open
the restrictor on the ow meter.
4. With the machine in the attachment mode set in
step 2 record the back-pressure. At this point the
pressure reading on the pressure gauge is the backpressure in the circuit. This pressure must not exceed 200 psi/13.5 bar.
Excessive back-pressure will slow the attachments
operation and lead to premature seal failures and
over heating.
Record the back-pressure psi.
5. Close the restrictor valve on the ow meter until the
attachment relief starts to crack or open. The relief
valve opens when the ow rate (GPM), indicated on
the ow meter begins to decline rapidly. Locate the
tools operating system relief pressure in the speci-
cation section in the manual. Adjust attachment re-
lief to specication.
NOTE:
The relief valve pressure must be greater than the
operating pressure of the attachment and three
times the back-pressure. Never use the relief valve
to control the ow rate in the circuit. Cracking pressure means the loss of 4 or more GPM.
Record the relief cracking pressure psi.
Example:
Operation pressure of a breaker is 2700 psi. Back-pressure is 150 psi. A good rule to follow when setting the
relief, multiply the back pressure by 3 then add this number to the operation pressure of the attachment.
Operating Pressure 2700 psi
Back-pressure 450 psi
Operating pressure of the tool 3150 psi
The relief valve setting must be greater than the estimated operating pressure of the tool. If the setting is lower,
damage to the circuit may occur. Excess heat will be
generated in the circuit which will damage the attachment and carrier.
MB05 User Manual ◄ 23
FLOW TEST PROCEDURES
HEAT LOAD TEST
With the installation kit properly installed and adjusted
per the above procedure, conduct the heat load test as
follows.
1. Connect the ow meter between the tool inlet and
outlet hoses.
2. With the carrier set in the attachment mode, re-
strict the ow meter until a pressure of 1000 psi
is achieved. This pressure must be maintained
throughout the heat test.
NOTE:
Closing of the restrictor may be required as the tem-
perature increases.
Monitor the oil temperature from the ow meter until
no change is noted. Record the time required for oil to
stabilize. Record the surrounding temperature (ambient temperature). Record the time required to stabilize
minutes.
Record the stabilized oil temperature ° F.
Record the ambient temperature °F.
The “heat rise” is calculated as the stabilized temperature minus the ambient temperature.
Example:
Stabilized Temperature 160°
Ambient Temperature -80°
Heat Rise 80°
The normal operating temperature range of this circuit
will be the typical ambient temperature range for the
geographical area plus the heat rise calculated above.
Ensure that the operating temperature range is lower
than 180° for optimum operation of the attachment.
TROUBLESHOOTING
If adequate pump ow is available from the carrier
pump(s) but is not getting to the attachment, consult
your service representative and review the following:
3. Attachment valve(s) are not actuating. Review all
electrical connections that are part of the attachment kit.
4. Ensure proper voltage to the valve(s).
5. Ensure the REG port of the valve is not blocked.
6. Check to make sure the carriers main relief is set
to the manufacturers recommendation and that this
value is equal or greater than the attachment circuit
relief.
7. If the valve will not turn off, check the drain (tank)
line of the valve to ensure that the pressure is 50
psi or less.

DEFINITION OF TERMS
Tool: The hydraulic attachment that the auxiliary circuit is intended to power. These
may include hydraulic breakers, compactors, shears, etc.
Operating Pressure: That pressure at which the tool will naturally operate without inuence of out-
side pressure relief mechanisms. This pressure is an operating characteristic
of the tool and cannot be altered by the end user without changing the tool
design.
Relief Pressure: The relief pressure is that pressure at which the circuit will dump uid in order
to protect itself from damage.
Back Pressure: The pressure at the tool’s connection to the return circuit of the carrier.
Flow Meter: Instrument for testing the operating characteristics of a hydraulic circuit. The
data usually available from this device are pressure (psi/bar), ow (gpm/lpm)
and temperature (°F/°C).
Restrictor Valve: A valve on the ow meter which allows the user to simulate an operating tool
by adding a pressure load (through restriction) to the circuit. This feature is
used to evaluate relief settings and ow ratings at pressure.
V60/V65/V100 Valves: A priority ow control valve manufactured by Stanley Hydraulic Tools. Allows
for optimum operation of any attachment by providing the proper amount of
ow for operation of the tool the “priority” aspect allows the attachment to function properly if another control function is activated.
Inlet Flow: The hydraulic oil supplied to the IN port of the tool or valve.
Regulated Flow: The ow of oil supplied to the tool by the V60/V100 valve.
By-Pass Flow: The oil ow that is supplied by the carriers pump, but not used in the opera-
tion of the attachment. By-pass ow equals inlet ow (to the valve) minus the
regulated ow.
Pressure Line: The hydraulic line(s) that supply pressurized oil from the pump to the valve or
tool.
Return Line: The hydraulic line that connects the OUT port of the tool to the tank circuit of
the carrier.
Cracking Pressure: The pressure at which the relief valve starts to open. Can be seen by a drop in
the ow rate as shown by the ow meter.
Full Open Pressure: The pressure at which the relief valve is completely open dumping all system
ow to the tank.
Ambient Air Temperature: The temperature of the outside air.
Stabilized Temperature: The temperature at which the carrier hydraulic system temperature will stop
rising during testing or operation.
