Tooling Installation Safety
Tool setting is a very important job. Safety of the operator, press brake and the tooling is
involved. To properly prepare for the job, the tool setter should have a good working
knowledge of press brakes, tools and materials. The person should also have been
instructed in the use of tool trucks and other handling equipment. The person must also
understand the importance of proper tool adjustment.
Aside from the technical knowledge the setter must develop a sense of personal safety
awareness. It is not only important that tools are correctly installed in the proper size of
equipment; the task must be accomplished in an organized and safe manner to complete
the job.
The following steps offer a precautionary guide in the development for safe tooling
installation procedures.
1. Immediately report any questionable operation, unusual action, unsafe
condition or improper maintenance to the proper personnel.
2. NEVER at any time allow fingers or hands to be between the tools.
3. When working with other people insure that all persons are clear of the press
brake prior to any ram motion (jogging, inching or cycling).
4. Insure that the proper safe material handling equipment (tongs, pliers, vacuum
lifters or other mechanical devices) available to the press brake operator.
5. When changing the settings of press brake controls, insure that the controls are
properly adjusted and test cycle the machine to verify correct operation.
6. Any locking type of controls should be adjusted by authorized personal, and
the key must be removed to a secure location when not being used.
7. Insure that all devices are in proper working order.

8. Anytime that the machine has been left unattended or inoperative for even a
brief time, verify the correct position of all controls and proper press brake
operation.

9. Develop a sense of safety for yourself and any persons around you as well as
your surrounding area.

Introduction
The Piranha press brake is a heavy duty, high performance hydraulic powered
machine that provides several important advantages surpassing other press brakes in
today’s market. The Piranha’s single hydraulic cylinder mechanical linkage system
provides full tonnage at any point across the bed.
The machine is shipped fully assembled requiring only hydraulic oil and electric
power to become fully operational. The heavy steel “C” frames, interlocking cross
members, ram and bed provide the integrity and resistance to deflection that is
necessary for accurate performance. State of the art, maintenance free, aerospace
Garfil bushings provide high load capacity and low friction in the form of a thin
walled sleeve. They are completely non-metallic and require no lubrication. Hardened
micro-finished oversize link pins allow the linkage to withstand high load forming
and punching applications.
Other standard features include: emergency stop button, Generation II control system,
bed tilt adjustment, spring open die clamps with hardened clamping bolts. Hardened
& ground ram slides with non-metallic ram gibs, PRS, precision ground die rail
drilled and tapped on both sides with hold down bolts, die rail centering adjustment
bolts and a sturdy 36" micro-adjustable back–gauge for simple, accurate and fast
setting.
The precision model offers ram repeatability of +/- .0004" This machine is equipped
with a Hurco CNC unit as standard. The Hurco CNC must be in use and the Finishing
Speed function must be turned on to achieve +/- .0004” repeatability.

Installation
BEFORE INSTALLING THIS PRESS BRAKE, READ AND UNDERSTAND
THE PRESS BRAKE MANUAL WITH PARTICULAR ATTENTION TO
“SAFETY TIPS FOR MAINTENANCE PERSONNEL” THE CURRENT ANSI
B11-3 STANDARD-“SAFETY REQUIREMENTS FOR THE
CONSTRUCTION, CARE AND USE OF POWER PRESS BRAKES.”
Copies can be ordered from: American National Standards Institute,
1430 Broadway, New York, New York 10018

Unpacking
CAUTION: THE PRESS BRAKE IS HEAVY IN FRONT. GUARD
AGAINST TIPPING UNTIL ANCHOR BOLTS ARE SECURED.
This machine was carefully packaged at the factory to avoid damage during
shipment, should any accidental damage occur contact the responsible freight
company immediately and report the damage. Indicate any damage on the Bill of
Lading. All Warranty information included in this packet must be returned to
the factory.

Figure 1: Lifting Lug Location
The Piranha 95 Press Brake must only be lifted using a crane, and the lifting lugs
located in front of the hydraulic oil tank on top of the machine. Do not lift the
machine from the bottom (forklift or jack) as the machine is top and front heavy
and can tip resulting in serious bodily harm or death. Lifting the machine from
the bottom can also result in machine damage.

Placement
Piranha recommends that the machine be placed on a reasonably level concrete
foundation suitable to support the press brake’s total weight and in accordance
11

Piranha 95 Operator's /Owner's Manual
with local building codes. The machine should be placed on a single concrete
pad free of cracks and seams. Prior to anchoring or setting, the press brake
should be leveled and shimmed. A section (0) on leveling is included in this
manual. Anchoring can be accomplished using suitable masonry anchors.
Typically, only the rear feet of the machine need to be anchored. Use the
machine as a template for anchoring hole locations. Placement of the machine
should allow easy access around the machine for the operator and maintenance
personnel. For safe operation placement should allow tooling to be installed onto
the bed from the end of the machine.
It is recommended that a minimum four-foot area around the Piranha 95 Press
Brake be provided.

Initial leveling
CAUTION: THE PRESS BRAKE IS HEAVY IN FRONT. GUARD
AGAINST TIPPING BEFORE AND DURING LEVELING.
Level adjusting screws are only provided on the rear feet. The Piranha
95 Press Brake must be placed on four steel pads: 2 each 6" x 6" x ¾"
for the front feet and 2 each 6" x 6" x ½" for the rear feet. These pads
are provided with the press brake.

Figure 2: Leveling Plate /Foot Detail

1. Position the 3/4" thick pad under each of the front feet (see
Figure 2 Item 1).
2. Position the 1/2" thick pad under each of the rear feet (see
Figure 2 Item 3).
12

Piranha 95 Operator's /Owner's Manual
3. Before the riggers disconnect the lifting apparatus, check the
press brake for rough level from the left to right plane.
4. Using a machinist square level, shim the front feet until the
machined bottom surface of the Ram is level left to right.
Desired level is within .005”-.015” inch per foot. A jack
angle is located on the inside of the right C-frame to assist in
leveling the machine right to left. Because of bed tilt feature,
the bed cannot easily be used for leveling.

Cleaning
Clean the die rail, bed surface, punch holder pocket and die clamps with a mild
solvent so as not to damage the paint finish on the machine. The main cylinder
rod must also be free contaminants. Any contaminants left on the cylinder rod
may damage the chrome finish and related hydraulic seals. The cylinder rod
must be clean and dry. Wipe down the rest of the press brake with a mild
cleaning solution.

Piranha 95 Operator's /Owner's Manual

Precision Leveling
The Piranha 95 Press Brake must be leveled precisely prior to operation. The
following steps represent the typical leveling procedure. These instructions must
be followed to avoid damaging the machine.
This procedure will require that the press brake have electrical power connected
and hydraulic fluid installed. The press brake must be functional enough to lower
the ram to the bottom stop position.

Ram
Table 1: Ram Slide Location Explanations
1. Before beginning the leveling procedure, turn on the press brake
and lower the ram to the bottom of stroke position, then turn the
press brake off.
2. It is important to keep in mind that the left and right side need
only to be parallel with each other, rather than perpendicular with
the floor.
3. Using a machinist square level having an accuracy of .0005” inch
per foot graduation, place the level firmly against the front face
of the right vertical ram slide as shown. (See Figure 3 Item1)
14

Piranha 95 Operator's /Owner's Manual
4. Adjust the rear-leveling bolt until the bubble on the level is
centered.
5. Repeat this procedure for the left slide. Adjust leveling bolts as
required.
6. The side frames must be parallel to each other within .0005” per
foot.
7. Once the machine is level, place shims, having a thickness equal
to the gap between the base plate and the bottom of the press
brake foot under the foot.
8. After the shims are in place, lower the adjusting bolts and recheck the level to ensure that the left and right sides of the
machine have remained parallel to each other. The overall shim
pack height may need to be adjusted in order to maintain side
frame parallelism.
9. The machine may now be anchored to the floor using concrete
anchor lugs.
10. After tightening the floor anchor lugs, re-check the press brake
level to ensure that the machine has not moved.

Electrical
CAUTION: ELECTRICIANS CHECKING DIRECTION OF ROTATION
SHOULD BE CAUTIONED NOT TO OPERATE THE PRESS BRAKE
UNTIL IT HAS BEEN THOROUGHLY CHECKED, CLEANED, LEVELED
AND LUBRICATED. A WIRING DIAGRAM IS FURNISHED IN THIS
MANUAL. THE PRESS BRAKE OPERATING MODE MUST BE IN THE
OFF POSITION WHEN CHECKING MOTOR ROTATION.
BEFORE DRILLING ANY HOLES IN THE ELECTRICAL ENCLOSURE,
BE SURE THAT THE ELECTRONIC CIRCUIT BOARDS/EQUIPMENT
ARE PROTECTED FROM METAL CHIPS CONTACTING THE CIRCUIT
BOARD(S). DO NOT USE COMPRESSED AIR TO BLOW METAL
DEBRIS FROM THE ENCLOSURE. USE A VACUUM TO REMOVE
ANY METAL PARTICLES.
Voltage requirements may be determined by comparing the fuse part number to
the chart located on the inner door panel of the main electrical box. (See Figure 4)

Piranha 95 Operator's /Owner's Manual

Figure 4: Fuse Size Chart
Electrical connection of the 3-phase systems requires proper phasing. When
connecting the press to a 3-phase power source, the rotational direction of the
pump drive motor must be correct. . The motor must rotate in the direction of the
arrow on the electrical motor (see Figure 6).
A licensed electrician should perform all electrical connections.

Warning - The control transformer is for machine operation only. Do not
use the machine transformer to power any secondary devices.

If a CNC back-gauge is installed on the machine, a dedicated 115-VAC, 60Hz,
20-Amp fused service must be provided for the backgauge system. l

Connecting the Pedestal Control
Prior to operation, the pedestal control plug must be attached to the main
control panel. To connect the plug, locate the receptacle on the bottom of
the main electrical control box. Align the plug with the receptacle.
Insert the plug and rotate the outer ring securing the plug to the
receptacle.

Piranha 95 Operator's /Owner's Manual

Hydraulic
Before applying power to the Piranha 95 Press Brake, the hydraulic reservoir
must be filled with oil. To fill the reservoir, locate and remove the filler/breather
cap on top of the reservoir. Fill the reservoir with Mobil DTE-13 or ISO32
equivalent, filtered to an ISO 17/15/13-cleanliness level. The proper oil level is
between the red and black lines of the sight gauge found on the rear of the
reservoir (See Figure 5). Do not over fill the reservoir. Replace the filler/breather
cap.

Figure 5: Oil Level & Temperature Sight Gauge

Piranha 95 Operator's /Owner's Manual

Filling the Pump Case
Prior to starting the motor for the first time, remove the pump case drain
tube from the hydraulic pump and fill the pump case with hydraulic
fluid. Reconnect the pump case drain tube. If the motor is run in
reversed rotation, this procedure must be repeated. The pump case must
be filled with hydraulic fluid upon start up.
WARNING: Failure to follow this procedure may lead to pump damage
and premature failure.

Motor Rotation
Motor rotation can be verified by quickly “Bump Starting” the motor
(starting and stopping quickly) and viewing the fan blade rotation
through he fan blade shroud. The rotation direction of the motor fan
blades must correspond with the direction arrow on the motor.
If the fan blades are obscured, use a flashlight to view the fan blades
from the grease zerk slot on the fan shroud. Shine the light towards the
fan blades and view the fan blade rotation.
Upon initial start-up of the hydraulic unit visually inspect around the
machine for any possible leaks. Do not search for hydraulic oil leaks
using exposed flesh; hydraulic pressure can puncture the skin.

turned off. The battery has a nominal lifespan of three years after which time the battery
discharges and all stored jobs will be lost if not saved to a memory tag. Stored jobs will also
be lost when the battery is replaced unless jobs are “backed up” on a memory tag.
The backup procedure is detailed here:
1.
Turn off main power to electrical enclosure.
2.
Open enclosure door.
3.
Insert Memory Tag into slot on front face of GII control module (Orientation does

Operating Parameters (Key required for access)
Initiation means
Hand: When the switch is in the “Hand” position the machine is controlled from the TwoHand control. The palm buttons must be engaged simultaneously to initiate a press cycle.
Foot: When the “Foot” mode is selected, the press is controlled by the footswitch alone.
Hand/Foot: This is a sequencing mode of operation that utilizes both Hand and Foot modes.
Ram movement is initialized by Hand mode and then transferred to Foot mode at the speed
change position. Simultaneously depressing and maintaining both of the palm buttons
initiates the sequence. At the speed change position, the ram stops and control is transferred
to the footswitch. Activation of the footswitch will complete the ram cycle.
Foot/Foot: This is a sequencing mode of operation that utilizes a double Footswitch
actuation. Operating the footswitch control initializes Ram movement. The pressbrake ram
travels downward in approach speed to the speed change point, where the ram stops
movement. Reactivation of the footswitch will complete the ram cycle.
Run modes
Off: When the “Off” mode is selected, all Press Brake movement (up or down) is disabled.
Only the hydraulic motor can be started when the Operating Mode switch is in this position.
Inch: When the Inch mode is selected, the Press Brake ram will descend when the palm
buttons are actuated. Releasing the palm buttons will cause the ram to stop. Re-initiating the
palm buttons will restart downward ram movement. At the bottom of stroke position the ram
will stop, and must be raised by depressing the Ram Up button. This mode is useful for
setting or changing tooling, and setting up a job.
Run 1: When the Run 1 mode is selected, the ram will descend when the dual palm buttons
are depressed. When the dual palm buttons are released at any point during the down stroke,
the ram will pause. Downward motion will resume when the dual palm buttons are reactivated. The ram will automatically return to the top of stroke position when the bottom
stop position is reached.
Run 2: When the Run 2 mode is selected, the ram will descend when the dual palm buttons
are depressed. When the dual palm buttons are released during the down stroke, or when the
bottom stop position is reached, the ram will automatically return to the top of stroke
position.
Run 3: When The Run 3 mode is selected, the ram will descend when the dual palm buttons
are depressed. When the dual palm buttons are released during the down stroke, the ram will
stop. When the ram reaches the bottom stop position, the ram may be “inched” up by
“toggling the dual palm buttons. Run 3 will allow the operator control of the ram with the
dual palm buttons during the return stroke

Finishing Speed
Finishing speed is incorporated into the control configuration to permit the press
brake ram to enter a slower pressing speed, enabling a greater degree of ram
repeatability.

Piranha 95 Operator's /Owner's Manual

Ram Return Modes
Low
Low, or “slow” return when selected, is a function where the ram will return slowly
from the bottom of stroke to the top of stroke.
Low / High
Low, or “slow” return when selected, is a function where the ram will return slowly
from the bottom of stroke to the original speed change point. At the speed change
point, the ram will revert to the normal or “high” return speed
High
High-speed return when selected, is a function where the ram will return ito the top of
stroke position in the high speed.

Note: Do not adjust bed tilt with the bed under load.

Piranha 95 Operator's /Owner's Manual

Tooling Installation
Before attempting to install, set or remove any tooling from the press brake, the safety section
of this manual must be read and understood.
The exact procedure for installation, setting and removal of dies may vary with the type of die
used. The following steps are a generalized representation and may be tempered to suit the
particular application, though not to the extent of being unsafe.
Always review the instructions provided in this manual and observe the press brake safety
rules!

NEVER install chipped, cracked, or damaged dies.

Insure that the die is of the correct size and type for the press brake, reducing the risk of
overloading the machine.
Insure that no tools, bolts or other items are in the die area prior to operating the press brake.
Locate any available safety handling tools required.
Keep the floor and surrounding area clean and free of obstruction, debris and oil.

Press Brake Preparation
1. Start the hydraulic power unit.
2. Lower the ram to the bottom position.
3. Remove all power from the press brake.
4. Turn the operating mode to the Off position.

Die Insertion

NEVER at any time allow fingers or hands to be between the dies.

1. Insure that the Press Brake Preparation procedure has been completed before
continuing with the insertion of dies.
2. Loosen the die rail set screws and punch clamps.
3. Insert the lower die from the end of the press brake, leaving several inches
overhanging the end of the bed
4. Measure the distance between the ram and the lower die to the punch height,
verifying sufficient clearance for insertion of the punch.
5. Adjust the position of the ram as required to allow the punch to rest on the lower
die with the tongue of the die engaged in the punch clamp.
6. Safely transport the punch to the press brake and rest it on the extended portion of
the lower die, aligning the tongue of the punch with the ram groove.
37

Piranha 95 Operator's /Owner's Manual
7. Slide the punch into the punch clamp groove aligning the ends of the punch and
lower dies.
8. Adjust the ram bottom position to make the dies “kiss,” forcing the punch to fully
engage in the punch clamp groove.
9. Tighten the punch clamps and the die rail set screws, securing the dies in the press
brake.
10. Return the ram to the up position.

Tooling Removal

NEVER at any time allow fingers or hands to be between the dies.

1. Lower the ram until a few thousandths gap exists between the punch and lower
die.
2. Loosen the die rail set screws and punch clamps.
3. Raise the ram position slightly upward and verify that the punch will remain
resting in the lower die. If not, the punch clamps may require further loosening.
4. If additional clearance is required to allow die removal, adjust the ram position to
loosen the die yet keep it well confined.
5. With the punch partially disengaged and guided in the loosened punch clamps,
push both the upper and lower dies several inches out the end of the press brake.
With hands at the end of the dies, push the dies from the end. NEVER place hands
or fingers between the dies.
6. Properly position the die transport device at the end of the press brake to accept
the punch.
7. With hands at the end of the punch, push the punch towards the transport device,
allowing several inches to remain in the punch clamp.
8. Prepare the transport device to completely support the punch, securing the punch
from falling as required.
9. Position the transport device to accept the lower die and slide it from the bed.

Piranha 95 Operator's /Owner's Manual

Tool Adjustments
The following steps are a generalized representation and may be tempered to suit the
particular application though not to the extent of being unsafe. It is a good practice to
allow for several sample parts during set up operation, lowering the ram in small
increments until the desired bend is achieved without overloading the machine.
1. Insert a sample piece of material.
2. Adjust the ram limits as required until the desired bend angle is attained. Avoid
over- adjusting the ram.
Note: Shimming may be required to compensate for punch and die wear and any bed
or ram deflection.

Tonnage Requirements
See bending tonnage chart located on side of press brake for approximate bending
requirements.

Die Rail Shimming
The Piranha 95 Press Brake is manufactured without a crown in the bed. Occasionally due to
deflection, shimming may be required. If shimming is required under the die rail, shims must
be placed in progressively thicker increments from each end of the bed (see Figure 10).
Typically, shimming is required to compensate for bed deflection and must be performed by
trained personnel. The following diagram is for reference purposes only as each application
will have different requirements.

Figure 10: Die Rail Shimming Example

Piranha 95 Operator's /Owner's Manual

Maintenance Procedures
BEFORE MAINTAINING OR REPAIRING THE PRESS BRAKE, READ AND
UNDERSTAND THE CURRENT ANSI B11.3 STANDARD.
This section describes the procedures and requirements for maintaining and repairing the major
components of the Piranha 95 Press Brake.

Maintenance Schedule
This section outlines the suggested points and intervals for regular scheduled
maintenance. The hydraulic power unit is very sensitive to dirt and other contaminants,
but will provide many years of reliable service with a minimum amount of service. The
operating temperature and the cleanliness of the oil directly affect the life of the hydraulic
oil. Regular oil and filter changes will keep the system clean and free of sticking and
clogged valves. Because hydraulic cylinders are lubricated with every stroke, keeping
them clean and free of scratches and dings that may damage the cylinder rod seals is most
important.
The Piranha 95 Press Brake is shipped with an extra hydraulic oil filter. It is important
that after the first forty hours of operation the oil filter be replaced. Upon using the
included extra oil filter it is suggested that a replacement filter be ordered for the next
scheduled filter change.
See parts list for correct filter part number.
1. After First 40 hours:
• Change hydraulic filter
• Check fluid level
• Check gib clearances
• Grease ram slides
• Clean oil cooler by blowing air through radiator portion of the cooler
• Check fittings, bolts, nuts for tightness
2. Every 40 hours (weekly) thereafter:
• Grease ram slides.
• Clean oil cooler by blowing air through radiator portion of the cooler
• Check fittings, bolts, nuts for tightness
3. Every 3 months:
• Change hydraulic filter
It is recommended that the filter element be changed every 3
months depending on workload and environmental conditions. See
repair parts list for re-ordering instructions and the part number.
• Check hydraulic fluid level
• Check gib clearances
4. Every Year:
• Grease electric motor
5. Every Two (2) years:
• Change hydraulic fluid
40

Piranha 95 Operator's /Owner's Manual

Gib Clearance Adjustment
Proper maintenance of the gibs will require periodic adjustment of the gib clearances.

Gib Adjustment
1. Position the press brake ram so the ram slide is in full contact with the gibs.
2. Loosen the Rear Adjustment Screw Jam Nuts on both ends of the press brake.
(See Figure 11 Item 1)
3. Using a torque wrench of the correct torque range, torque the top and bottom
setscrews to 150-in. lbs. (12.5-ft. lbs.).
4. Tighten the remaining setscrews (between the top and bottom setscrews) to the
same torque.
5. Repeat steps 2 & 3.
6. Back off the setscrews 1/8 turn and tighten jam nuts.
7. Repeat this procedure for the other end of the press brake.

Side Thrust Gib Adjustment
1. Position the press brake ram so the ram slide is in full contact with the gibs.
2. Verify that the ram is aligned with the bed (left to right).
3. Loosen the Slide Mounting Bracket Jam Nuts on both ends of the press brake.
(See Figure 11 Item 2)
4. Using a torque wrench of the correct torque range, torque the top and bottom
set screws to 150-in. lbs. (12.5-ft. lbs.).
5. Repeat step 3 on opposite end of the press brake.
6. Tighten the remaining setscrews (between the top and bottom setscrews) to the
same torque.
7. Repeat step 3 on the opposite end of the press brake.
8. Re-torque the setscrews on both ends of the press brake.
9. Back off the setscrews 1/8 turn and the tighten jam nuts on the left side of the
press only.
10. Tighten the jam nuts on the right side of the press brake.

should attempt to perform adjustment procedures on the unit. The power unit generates
very high pressures. Never check for leaks using hands.
Before servicing the hydraulic system, block the ram and turn power off.

Oil Filter Replacement
Verify the exact element number prior to ordering the replacement element.

The tooling used in a press brake for forming
metal.

Die Holder

The plate or rail to which the lower portion of
the die member is attached.

Die rail

See die holder.

Die Shimming

Method to raise for fill a void between two
surfaces. Typically used to compensate for
machine deflection or worn tooling.

Die Space

The space between the bed and ram.

Dies, Bending

Dies used in press brakes to perform
bending and forming operations on a variety
of work pieces.

Electrical Spike

An unpredictable and infrequent momentary
high electrical voltage which can harm
electrical/electronic devices.

Encoder

A device typically electromechanical, that
translates motion into electrical pulses. See
also Resolver, Tachometer, or Transducer.

The branch of mechanics, which uses
controlled hydraulic oil flow, and pressure to
provide force to an actuator.

Inertia

A property of matter by which it stays at rest
or in uniform motion in the same straight line
unless acted on by an external force.

Lifting lugs

Steel plates with large holes that are
attached to the press brake to assist in lifting
the machine.

Pressure Reducer

Typically, a hydraulic component that senses
secondary pressure to maintain that output
pressure regardless of the incoming
pressure.

Pressure Relief

Typically, a hydraulic component that uses a
spring to hold an orifice closed until system
pressure overcomes the spring and allows
flow to the reservoir.

Proximity Sensor

An electrical device capable of detecting the
presence of an object.

PSI

Acronym. Available Force expressed in
Pounds per Square Inch

Punch

The male part of the tool (die).

Pushbutton

A small button or knob actuated by pushing,
provided for operator control, electrical,
pneumatic, or mechanical.

Ram

The linear moving press brake member
configured to carry a portion of the tooling.

Relay

An electromechanical device for remote or
automatic control that is actuated in variation
of conditions of an electrical circuit and that
operates other devices in an electrical circuit.

Repeatability

The closeness of agreement among multiple
measurements of an output, for the same
value of the measured signal under the same
operating conditions, approaching from the
same direction for full range traverses.

Reset

To restart or arm a control or safety system.

RPM

Acronym. Rotational speed expressed as
Revolutions per Minute.
