INTRODUCTION
Your new Bender is a “Press-Style” Bender that is capable
of bending, flaring and swaging Tubing up to 3 inches in
diameter. The thickness of the Tubing plays an important
part in bending. (See Specifications for recommended
Tubing allowances.) The front of the Bender is where all
the bending is performed. The Top Cylinder activates the
Bending or Radius Die which moves forward through the
Back Shoes. The Bottom Cylinder keeps pressure applied
to the Back Shoes by a chain assembly and integrated
Hydraulic Sequence Valve. In addition to the contoured
shape of the Radius Dies, resistance pressure is applied
to help the Tubing maintain it's shape.
DEFINITION OF TERMS
The following definitions explain the major components
and operating features of your machine. The RIGHT,
LEFT, and REAR sides of the Bender are relative to the
FRONT of the machine where all bending is performed.
BENDER- The whole machine including all end
finishing components.
BODY- The main 6” x 6” tubular structure that sits
horizontal to the floor and is located just below the Top
Cylinder.
SWAGING BOX- The expanding/flaring unit located to
the rear of the Bender which utilizes Pipe Collars in
conjunction with bullet shaped Expander/Forming Dies to
perform a variety of Tube end finishing.
INTERNAL EXPANDER- The Expanding/Flaring Unit
located to the rear of the machine that utilizes
Segmented Expander Dies. These “Segment Sets” are
expanded by the means of a taperedArbor pulled through
their center. This style of end finishing is usually required
with shorter pieces of Tubing such as Muffler Nipples
which do not allow the use of a Collar.
TOP CYLINDER- The main Hydraulic Bending Cylinder
located at the top of the Bender. Its primary function is to
activate movement of the Radius Dies.
BOTTOM CYLINDER- The Hydraulic Cylinder located
just below the body of the Bender. Its primary function is
to apply resistance pressure to the Back Shoes as the
Radius Die pushes through.
RESERVOIR- The rear vertical leg that contains the
Hydraulic Oil.
FRONT UPRIGHT- The front vertical leg.
BENDER MODELS
There are three different Bender models available.
BB (Blue-Bullet) 1302-BAS 1302-BA
The following is a brief description of their controls and
operating features. The model nomenclature consists of a
number (1302) followed by letters BA or BAS. The
numbers designate what style frame assembly is used
while the letters signify the control features.
FRAME CONFIGURATION
1302 Series - A machine capable of bending and end
finishing. Equipped with both a Swaging Tool and an
Internal Expander. A Double-Ended Hydraulic Cylinder is
used for both end finishing functions. The End Finishing
Assembly, (the Swaging and Internal Expander) is posi-
tioned “cross-wised” on the rear of the machine.

Bender Operation Manual 7
CONTROL FEATURES
BB or BLUE-BULLET Models - A Hydraulic Control
Valve is located at the front of the machine at knee height
that allows the operators to manually control the machine
with their leg. A Degree Plate is mounted up front that
shows proper bend depths. This model does not incorpo-
rate any automatic bending features.
BAS Models - These models have two different control
modes: an Electric Foot Switch assembly for manual
bending operations and a Three-Button Control Board for
automatic functions. The Bend Angle is shown on a
Degree Plate mounted near the front of the machine,
which also incorporates an adjustable Slide Pointer that
can be set to any desired Bend Depth.
The Control Board consists of three colored buttons;
GREEN, BLUE and RED; each with its own operating
functions. If you choose to use the machine in the
automatic mode, you would simply set the pointer to 90
degrees for example, then press the GREEN button. At
this time, the Bending Head would activate and the Radius
Die would begin to move forward. After the desired bend
depth has been reached, the machine would
automatically initiate the retract sequence that returns the
Die to the original starting position. The BLUE button
automatically returns the Die to the original starting
position, while the RED button is an emergency stop
control. The Electric Foot Switches will override the
three button controls.
BA Models - These models have two different control
modes; an Electric Foot Switch assembly for manual
bending operations and a Digital Control Board for
automatic functions. The Digital Control Board eliminates
the Depth of Bend scale and replaces it with a digital
readout labeled “DIE ANGLE”. It also offers the user the
capability to “program” certain bend depths in a desired
sequence. When the power is turned off, all memory is
erased. Once a bend depth is programmed into memory
the number appears in a L.E.D. display labeled “SET
ANGLE.” The bend sequence is initiated by pressing the
“AUTO” button. At this time the Die moves forward and
uponreachingthe desiredbenddepth immediatelyretracts
to the original starting position. An emergency “STOP”
button pauses the machine at any time, and an additional
auto “REVERSE” button activates the return sequence.
The Electric Foot Switches will override the digital
controls.
INSTALLING THE
ELECTRICAL PLUG
Before installing a plug on the end of the power cord it is
important to check for the correct Voltage, Phase, and
Current requirements. The tag attached to the end of the
power cord, or the Motor Data Plate plate will show this
necessary information. Due to the high Current and
Voltage required to operate this machine at long durations,
itisrecommendedthat you DO NOTUSEANEXTENSION
CORD LONGER THAN 15 FEET. This Motor must be
grounded. The GREEN wire is for ground only. All wiring
should be accomplished by a Licensed, Certified
Electrician only. Damage to the Motor caused by
improper wiring is not covered under warranty.

OIL FILL AND INITIAL START
UP PROCEDURES
WARNING!
Prior to operation, you must add approximately 4.5
gallons (17 liters) of Anti-Foaming Hydraulic Fluid
Oil ISO-VG Viscosity Grade AW-32 OR AW-46.
Due to current DOT and insurance regulations regarding
the transport of Hydraulic Oils, Hydraulic Fluid is to be
supplied by the end-user only. (DOT / Section 1 -
Hazardous Ingredients, DOT / Section 2 - Fire and
Explosion Hazards and DOT / Section 3 - Health Hazards)
WARNING!
Always ensure that all personnel who will be
operating or maintaining this machine read the
operating manual and maintenance instructions as
outlined in the Operation and Service Manual that
accompanies the equipment.
1. Use only new, clean Anti-Foaming Hydraulic Oil ISO-
VG viscosity grade AW-32 or AW-46.
2. Before filling the Reservoir, always clean the Filler-
Cap (Breather Cap) opening and surrounding area.
3. Use a filling device that incorporates a minimum 60
micron screen for filtration.
4. Observe the Sight Gauge marking for the maximum
fluid level. Pour in only enough oil to bring the
reservoir level up to the Sight Gauge full mark.
Approximately 4.5 gallons (17 liters).
7. Activate the Swaging and Expanding Cylinders by
pressing the directional controls located at the back
of the machine. Cycle the Cylinders to their full extent
at least five times.
8. The Hydraulic System will self-bleed any trapped air
in the system after approximately 10 minutes of
operation. Sufficient bleeding has taken place when
all Cylinder movements are smooth and free from
jerking or shuddering movements, and no abnormal
noises are present.
9. Verify that all Hydraulic Hose connections are tight.
After Initial start-up, it is usually necessary to
retighten Hoses or Fittings that may have loosened in
transit. When tightening Hydraulic Hoses, use a
second wrench on the Hex Fitting to ensure the Hose
does not twist during the tightening process. This will
ensure an proper tightening of the Hose without any
pre-loading conditions.
10. The final Hydraulic Fluid Level should be checked
when the machine has reached operating
temperature. Wait until the machine has warmed-up
and then add enough Hydraulic Fluid to bring the
reservoir oil level up to the full mark as indicated on
the Sight Gauge.
11. Replace the Filler Cap (Breather Cap).
TOOLING
Find the packing list that accompanied your Bender,
itemizing each Tool that was to be included in your Tooling
package. Double check the pieces you received with those
that were checked off. ALL THE TOOLS THAT ARE
CHECKED OFF IN THE “SHIPPED” COLUMN DID SHIP
WITH YOUR BENDER. If you cannot find a certain piece
that you feel should be with the shipment, check with the
freight carrier or observe the packing list and check the
back ordered column. If a certain item is back ordered it
will be automatically forwarded to you. A description of
Tooling is listed below.
RADlUS DIES- These Dies which are commonly referred
to as the “Bending Dies” come in different radii and Tubing
sizes. Each Die is machined and sized according to Tubing
diameters. The proper Tubing size is stamped on the top
of each Die. 112 represents 1-1/2” Tubing, 134 represents
1-3/4” Tubing etc. The Radius Dies are available in three
standard radii, 5”, 4” and 3-1/2”. Each standard Radius Die
represents half of a circle or diameter. 180 degree Dies are
also available which represent three quarters of a circle
and allow the Tubing to “wrap” around farther although the
radii are the same.
Do not allow Oil
to fall below
this point.
Sight Gauge
Breather Cap,
remove to add Oil.
5. Plug the Power Cord into the receptacle closest to the
available circuit panel.
6. Turn the Power Switch on, then operate the
Directional Control Valves and allow the Cylinders to
move in and out a number of times.
8 Bender Operation Manual

BACK SHOES - Back Shoes, which are commonly
referred to as Wiper Dies come in pairs and are used
together with the Radius Dies during the bending process.
These Dies play an important part as their primary pur-
pose is to form the outside radius of the bend. These Dies
are used to clamp or retain the pipe as it is wrapped
around the Radius Die. Each Back Shoe is machined and
sized according to Tubing diameter. The proper Tubing
size is stamped on the top of each Back Shoe.
NOTE:
Back Shoes should be kept clean and lightly oiled.
Never use the Bender without Back Shoes in
place. Never use the Bender as a Vice or a Press.
HALF SHOES and THREE-QUARTER SHOES - Half
Shoes and Three-Quarter Shoes do not come in pairs.
Only one is required. Half Shoes are exactly half the
length of a standard Back Shoe and three quarter Shoes
are three quarters the length. These smaller Shoes are
required when an upcoming bend is less than ten inches
from an existing bend. The half/three-quarter Shoe will be
used in conjunction with the Back Shoe and placed only
on the side where the full Back Shoe may interfere with the
upcoming bend. (Details for the proper use of these Tools
are explained in the BENDING section.)
NOTE:
Half Shoes and Three-Quarter Shoes must be used
with Radius Dies and Back Shoes of the same
corresponding size.
HAC's & STED's - HAC's are commonly referred to as
“Adapter Collars” while the STED's are referred to as
“solid Expander Dies”. HAC's are used to hold or clamp
the Tubing in place when performing end-finishing
Operations or when using the STED's. These Adapter
Collars are heat treated which causes the inside threads
or “teeth” to become brittle. Because of this, these “teeth”
have the tendency to chip during normal use. This is
normal and will have no effect on their performance. The
STED's or “solid Expander Dies” are used to expand the
Tubing to exact inside diameters and are also used to
create Male Ball Expansions. Both Tools are stamped and
marked with their appropriate Tubing sizes. (Details on the
proper use of both Tools is explained in the END
FINISHING section on page 22.)
NOTE:
Keep Collars free of debris and build up. Use a
wire brush periodically to clean the inside
threaded area. Keep all Tooling lightly oiled.

END-FINISHING TOOLS - A variety of End Finishing
Tools are available that perform different functions. Not
every Tool is included with your Tooling package. If you
are unsure as to what was included, please consult your
distributor or review the delivery receipt and invoice. Each
Tool is marked with the appropriate size.
HPF-300- ATool for making 45 and 90 degree Flanges on
Pipe Ends. Usually for Manifold connections.
DD-134/212-ATool for Doming Pipe Ends or making Male
Ball Expansions when used in conjunction with the Male
Ball Expanders.
DD-134/212 & BFED-200/214 - Tools for flaring pipe ends
to make Female Ball Expansions. Each Tool is “stepped”
and has the ability to flare two different sizes. The BFED-
134/214 is used for Tubing sizes 1-3/4” and 2-1/4” while
the BFED-200/212 is used for Tubing sizes 2” and 2-1/2”.
B-212 - A Tool used for making Male Ball Expansions on
2-1/2” Pipe Ends.
CFT-200 & CFT-214 - Tools for making Manifold Flanges
on 2” and 2-1/4” Pipe Ends. Not included in standard
Tooling packages.
REDUCING TOOLS - Reducing Tools are used for
reducing or “shrinking” Pipe Ends to exact outside
diameters. Each Tool is marked with the appropriate size.
It is important to understand that the size marked on the
Tool will be the size that the Tubing will be reduced down
to. For example, a Tool marked 200 will reduce 2-1/4”
Tubing down to 2” O.D. and a Tool marked 214 will
reduce 2-1/2” Tubing down to 2-1/4” O.D.
Not included in standard tooling packages.
SEGMENT EXPANDERS - Segment Expanders or
“Segment Sets” come in a variety of sizes and shapes,
each performing it's own distinct function. Segment Sets
are used for short pieces of Tubing or when the Tubing
end is minimized due to an existing bend. They can also

STOP!
Before any attempt is made to operate this machine
it is important that you have read and fully
understand all operating instructions described in
this manual.

NOTE:
Practice the following bending steps without Tubing and
initiate a few “dry runs” until you understand the
operating features.
USING THE REMOTE FOOT SWITCHES OR AUTO
BUTTON
When using a Card System or bending a pipe, you are not
required to use the “Memory” function. Some operators
will use the memory function only when multiple pipes are
to be bent. The most popular method will be manual or
semi-automatic. When KEYPAD is lighted, the machine
will operate manually using the Remote Foot Switches or
JOG/FWD button or semi-automatically, performing one
bend at a time using the AUTO button. The actual Depth-
of-Bend angle will continuously appear in the DIE ANGLE
window any time the machine is running. To manually
operate the Bender, press the Right Foot Switch to
advance the Radius Die and the left one to retract it. The
Foot Switches will always override the automatic controls.
When using the Foot Switches, the Radius Die will NOT
stop at the SET ANGLE.
To bend one bend at a time using the AUTO button,
follow these step-by-step instructions:
1. Turn the Bender on and press the SELCT button
to illuminate the KEYPAD light.
2. Find out what degree of bend is required and enter it
by pressing the appropriate number keys.
This number will then appear in the SET ANGLE
window. If you make a mistake and improperly
enter the wrong number, simply clear the SET
ANGLE by pressing the CLEAR button, then
re-enter the proper information.
3. With the KEYPAD light illuminated, disregard any
numbers that may appear in the STATION window.
4. After installing a matched Die set, position the Tubing
so that you can begin bending.
5. Check your “Circle-of-Swing” for allowable clearance.
6. Press the AUTO button to initiate the semi-
automatic cycle.
7. At this time the Radius Die will begin to move forward
until it reaches the designated Depth-of-Bend
displayed in the SET ANGLE window. The
retract sequence will then automatically initiate,
reversing the Radius Die until it is fully retracted.
8. For the remaining bends, move the pipe over until
the next bend position or “center mark” is centered
between the Back Shoes. Repeat steps 5-7.
9. After all bends are completed, cut off the Tubing end
to match the existing pipe or master.
PROGRAMMING THE DIGITAL BOARD- Follow these
step-by-step instructions to properly utilize the MEMORY
feature. The PROGRAM DATA CONTROL Board stores
bend depths only. All data will be cleared once power is
turned off. The memory feature can be used when
bending multiple or individual pipes The following
instructions illustrate how to properly enter the data
which is shown on the Program Cards.
1. Press the SELCT button to illuminate the KEYPAD
light.
2. Press the RESET button to return the STATION
window to number one.
3. Using your program card, enter the first degree of
bend shown in the BEND-DEPTH column. Press the
appropriate number keys to display the recommended
bend depth in the SET ANGLE window. Now press
the ENTER key. You have just entered the first bend
depth in station number one.
4. Press the STEP button to change the station to display
the number “2”.
5. Using your program card, enter the second depth of
bend by pressing the appropriate number keys. The
number should appear in the SET ANGLE window. If
the information is correct press the ENTER key. You
have now entered the second bend depth in station
number two.

CAUTION!
If operating controls are malfunctioning, discontinue
use immediately. DO NOT attempt to operate
machinery until controls have been repaired.

6. Repeat these steps until all Depth-of-Bends have
been entered. Always remember to press the
ENTER key prior to advancing to the next station.
7. Now press the SELCT key to illuminate the MEMORY
light.
8. Press the RESET button. This will change the
STATION window to number “1”.
9. To double check the data that has been entered,
press the STEP key to advance the stations through
their appropriate sequence. Review the data that has
been entered. If you reach a particular station that is
incorrect, press the SELCT key to illuminate the
KEYPAD light, the SET ANGLE will show zero at this
time then press the appropriate number keys and
retain the data by pressing the ENTER key. After
correcting the improper data, press the SELCT button
to illuminate the MEMORY light and the RESET key
to reset the STATION window. Review the information
once again.
NOTE:
In order to store data into Program Memory the KEYPAD
light must be illuminated. Entered data will not be shown
in the SET ANGLE window until the MEMORY light is
illuminated.

want to use the Foot Pedals in conjunction with the
“Auto-Stop” pointer, position the pointer at the desired
bend depth and proceed by pressing the RIGHT Foot
Switch until the Radius Die stops at the pre-set bend
angle. Press the LEFT Foot Switch to retract the Radius
Die. Always be prepared to support the pipe as it is
released from the Dies.
OPERATING THE MANUAL
KNEE CONTROL
BULLET MODELS
Read the following section completely before attempting
any operation of this unit. All “Blue Bullet” models are
equipped with a Hydraulic Control Valve mounted at
knee height that allows the user to operate the machine
manually with their leg. A Degree Plate with pointer is
mounted near the front of the machine that gives the
user accurate bend depths. “Blue Bullet” models are not
equipped with any automatic features.
To operate the Manual Control Valve, move the handle to
the left or the plunger down to advance the Radius Die.
The handle must be fully engaged to properly control
Radius Die movement.
To retract the Radius Die, move the Handle to the right (or
Plunger up) to return to the original starting position.
Always be prepared to support the Pipe as it is released
from the Dies.
OPERATION NOTE / BULLET MODELS:
If the Control Valve Handle is pressed half way or
partially down during the bending operation, the Radius
Die may slow down or even retract slightly. To keep the
Bending Die at a controlled speed you must fully press
the Valve Handle. If you wish to advance the Radius Die
a few degrees only, instead of easing the handle down,
try “tapping” the handle.
BENDING OPERATIONS
There are basically two styles of bending that can be
performed on your new Bender. The first is PROGRAM
CARD BENDING which requires the use of PROGRAM
CARDS that contain instructional data for specific
applications. The second is PATTERN BENDING which is
the most popular method and duplicates pipes by using an
existing pipe or wire pattern as a master.
USING THE PROGRAM CARDS - The Program Card
Software contains bending data for specific applications.
The following instructions define each section of the card.
It is important that you read the entire card carefully before
attempting to bend. Due to the many cards and
applications covered, there may be some inaccuracies.
No responsibility is assumed by the manufacturer for any
consequences arising from inaccuracies found on the
program cards.
Bender Operation Manual 15
CAUTION!
Be alert at all times. NEVER place hands near
bending area or other pinch points when Motor is
running.

Look up the make and model of the vehicle using the
Exhaust Pro Software to find the "card" or "record"
number. Then locate the proper card/ record in the
Bend- Data Express software for proper card for specific
bending instructions. Exhaust pipes numbers start with the
letter “E” and tail pipes numbers start with the letter “T”.
DEFINITION OF CARD
SECTIONS:
YEAR - Gives the year of the vehicle that the card pertains
to.
DIAMETER - The original equipment factory
recommended Tubing diameter for that particular vehicle,
O/A LENGTH - Overall length of Tubing required for that
particular pipe. Also referred to as the cut-off point.
SIDE - When more than one section of Tubing is required
for a particular card number, this section shows if it is the
front, rear, left or right side.
SYMBOLS - Shows certain symbols that pertain to
individual bending instructions that are explained in
greater detail in the BENDING INSTRUCTIONS section.
The symbol section also includes the descriptive “F” and
“R” symbols that indicate how the pipe fits on the vehicle.
“F” means front and “R” means rear.
CENTER MARKS - Refers to the actual locations or
measurements that the bends will be located.
PIPE ROTATION - Shows in degrees what the correct
pipe rotation (or plane) is for each bend.
BEND DEPTH - Shows in degrees what the correct bend
depth is for each bend.
MAKE - Gives the make of the vehicle.:Chevrolet, Pontiac,
Ford, Chrysler, etc.
MODEL - Gives descriptive factors such as the model,
engine and frame size.
BENDING INSTRUCTIONS - Shows what Radius Die will
be used in addition to other Tooling such as half Shoes
and three-quarter Shoes. Also gives instructions on
reversing and certain end-fInishing requirements. Not all
applications will be shown on the card.
Follow these step-by-step instructions to bend the pipe
for the card shown above.
1. Select the proper Tubing size for the application as
called for in the DIAMETER SECTION of the card.
(See Recommended Tubing Chart on page 48) Wipe
Tubing to remove excess oil.
2. Install the correct Radius Die as called for in the
BENDING INSTRUCTION section. Two Back Shoes
are required unless otherwise specied. Place Tubing
in the Bender between the Back Shoes and Radius
Die with the greater portion of the Tubing extending
out the LEFT side of the Bender. This is necessary
so that you can mark the Tubing with the appropri-
ate CENTER MARKS shown on the card.
3. Engage the Bending Dies until the pusher block
springs are compressed and the Tubing is held
rmly. Carefully control the advancement of the
Radius Die so as not to dent or bend the Tubing at this
time. (See gure 1-A)
16 Bender Operation Manual
Sample screen shots of cards with specific bending instructions.
Figure 1-A

4. Using the program card, refer to the section marked
CENTER MARKS for the list of measurements in
inches where the di󰀨erent bends will be made. Each
CENTER MARK is measured from the left end of the
Tubing. Mark and number the CENTER MARKS on
the Tubing using a crayon or felt tip pen. The last
mark you make should be the cut o󰀨 point shown in
the O/ALENGTH section. DO NOT CUT THE TUBING
at the last center mark until the nal bend is
made. (See gure 1-B.)
5. Disengage the Dies and reposition the Tubing so that
the greater portion is now extending out the RIGHT
side of the Bender and the first CENTER MARK is
lined up with the center of the two Back Shoes.
6. Engage the Bending Dies until the pusher block
springs are compressed and the Tubing is held firmly.
(See figure 1-C)
7. Rotate the Tubing so that the weld seam on the Tubing
is facing up or at the 12 o'cIock position. The
pusher block springs are designed to hold the
Tubing secure but still allow rotation of the pipe.
Install the rotation dial on the RIGHT end of the
Tubing. Loosen the buttery nut if necessary and insert
the segmented expander inside the Tubing end.
Tighten the buttery nut until the rotation dial is secure.
8. With the rotation dial properly installed, rotate the
degree Plate not the Tubing so that the pendulum
pointer is showing ZERO. Make sure the buttery nut
remains tight.
9. You are now ready to make your first bend. At this
time you may program your depth-of bends on the
digital board as described in the DIGITAL CONTROL
OPERATION section, position the depth-of bend
pointer on BAS models, or elect to use the Electric
Foot Switches or manual Knee Control Valve. For
beginning operators, we suggest that manual controls
are used until you become more familiar with the
operating features of your machine
10. As described in the BEND DEPTH section of the
card, advance the Radius Die to 17 DEGREES, then
retract the Die to the original starting position. The
rotation dial should still show ZERO at this time.
11. Review the SYMBOLS section of the card and check
for any special instructions. On bend number two,
you will notice that a HALF SHOE is called for. Install
the HALF SHOE now. Unless a special instruction is
given to change the radius size, you will continue to
use the 3-1/2” radius through the remaining bends.
NOTE:
Always position the HALF SHOE or THREE-QUARTER
SHOE on the same side as the previous bend.
12. For the second bend, slide the Tubing to the LEFT so
that the second CENTER MARK is lined up with the
center of the Shoes.
(See gure 2-B.)
NOTE:
The weld seam on the Tubing should be directly in line
with the ZERO mark at this time. (See figure 2-A)
Bender Operation Manual 17
CAUTION!
Before advancing the Radius Die, check your
Circle-of-Swing for allowable bending clearances.
Figure 1-B
Figure 2-A
Figure 1-C

14. With the HALF SHOE in place and the second CENTER
MARK lined up at the center of the Shoes, advance
the Radius Die forward until the pusher block springs
are compressed and the Tubing is held securely.
Carefully control the advancement of the Radius Die
to prevent denting or bending of the Pipe at this time.
15. Now, rotate the Tubing, not the dial, so that the
pendulum pointer or dial indicator points to the proper
setting as shown in the PIPE ROTATION section of
the card. In this case the PIPE ROTATION will be
147 degrees. ALWAYS use the inside set of numbers.
(See figure 2-C)
NOTE:
The rotation dial is equipped with two scales.
The standard scale which is used for all
regular bending operations is positioned to the
INSIDE of the dial. The OUTSIDE scale is
used for bending “mirror images” or opposite
side pipes.
16. With the rotation dial properly set at 147 degrees and
the center mark lined up, advance the Radius Die to
11 degrees as shown on the card. Retract the Die to
the original starting position.
17. Review the SYMBOLS section of the card and check
for any special instructions. On bend number three
you will notice that a REVERSE / USE HALF SHOE
is called for.
IMPORTANT NOTE:
The ROTATION DIAL Degree Plate
MUST NEVER be moved after bending has begun.
ALWAYS be prepared to support the Tubing as it is released
from the Dies to prevent it from hitting the ground. If the dial
is accidentally moved during the bending process,
re-position the dial so that the ZERO mark is located at the
weld seam of the Tubing, or return to the previous bend and
position the pendulum pointer to the angle required for that
particular bend.
18. If a bending instruction calls for a REVERSE, remove
the Tubing and position the ROTATION DIAL on the
LEFT SIDE of the machine. Be careful not to move
the ROTATION DIAL Degree Plate during this process.
NOTE:
When a REVERSE is called for, the rotation dial
will be positioned on the LEFT side for that
bend only. If the SYMBOL section shows a
REVERSE again for the following bend, the
rotation dial MUST remain on the LEFT side. If
no REVERSE is called for, the rotation dial
MUST be returned to the RIGHT side.
19. For bend number three, REVERSE the Tubing and
install the HALF SHOE now. (See figure 3-A)
20. With the HALF SHOE in place and the third CENTER
MARK lined up at the center of the Shoes, advance
the Radius Die forward until the pusher block
springs are compressed and the Tubing is held
securely.
21. Rotate the Tubing, not the dial, so that the pendulum
pointer or dial indicator points to the proper setting as
shown in the PIPE ROTATION section of the card. In
this case, the PIPE ROTATION will be 250 degrees.
USE THE INSIDE set of numbers.Advance the Radius
Die to 7 degrees.
18 Bender Operation Manual
Figure 2-C
Figure 2-B
Figure 3-A

22. Review the SYMBOLS section of the card and check
for any special instructions.
23. On bend number four you will notice that a
REVERSE USE HALF SHOE is again called for. Keep
the ROTATION DIALon the LEFTside for this bend.
24. Advance the Radius Die forward until the pusher
block springs are compressed and the Tubing is held
securely.
25. Rotate the Tubing so that the pendulum pointer or
dial indicator points to 260 degrees.
26. Advance the Radius Die to 35 degrees then retract
the Die to the original starting position.
27. Review the SYMBOLS section of the card and check
for any special instructions for bend number ve.
28. On bend number five no special instructions are
shown. In this case, return the ROTATION DIAL to
the right side and install the full BACK SHOE. A
HALF SHOE is not needed for this bend. (See gure 3-B.)
29. Advance the Radius Die forward until the pusher
block springs are compressed and the Tubing is held
securely.
30. Rotate the Tubing so that the pendulum pointer or dial
indicator points to 223 degrees.
31. Advance the Radius Die to 18 degrees then retract
the Die to the original starting position.
32. Review the SYMBOLS section of the card and check
for any special instructions for bend number six.
33. On bend number six no special instructions are shown.
34. Advance the Radius Die forward until the pusher
block springs are compressed and the Tubing is held
securely.
35. Rotate the Tubing so that the pendulum pointer or
dial indicator points to 277 degrees.
36. Advance the Radius Die to 9 degrees then retract the
Die to the original starting position.
37. You are now finished bending the pipe. Remove the
ROTATION DIAL and cut the Tubing end off at the last
O/A mark. (See figure 3-C.)
38. Now check the BENDING INSTRUCTIONS section
and check for any END FINISHING requirements. On
this particular card, it calls for a FEMALE BUICK
BALL on the FRONT or “F” side of the pipe. See
page 12 for TYPICAL END FINISHING illustrations.)
PATTERN BENDING
To pattern bend, proceed as follows. In order to retain the
information for later use, save the information as described
below.
NOTE:
Print a blank program card like the one below to use as
a master to make additional copies for later use.
1. Select the proper Tubing size and Die set to do the job.
Try to match the radius size with that of the existing
pipe.
2. Place the Tubing in the Bender with the greater portion
of the Tubing protruding out the right side of the Bender.
3. Place the master pattern (existing pipe or bent wire) on
the top of the Back Shoes so that the rst bend is
centered between the Back Shoes.
Bender Operation Manual 19
Figure 3-C
Figure 3-B

4. Adjust the Tubing out the left side of the Bender so
that the Tubing end matches the length with that of
the master. (See gure 1-A) Secure the straight pipe
by advancing the radius die until the pusher block
springs compress.
5. Using a measuring tape, measure the distance from
the end of the Tubing to the center of the Back Shoes.
This is the measurement to the rst bend and should
be recorded in the CENTER MARKS section of a
blank card. (See gure 1B)
6. Place the ROTATION DIAL on the far right end of the
straight Tubing and secure by tightening the wing nut.
Center the ROTATION DIAL Degree Plate so that the
indicator points to zero.
ALWAYS USE THE NUMBERS CLOSEST TO THE
CENTER OF THE ROTATION DIAL. THE OUTSIDE
NUMBERS ARE FOR SPECIAL APPLICATIONS ONLY.
Record the rotation degree as zero for your
first PIPE ROTATION.
7. You are now ready to make your rst bend. Place the
rst bend of the master pipe or wire flat on top of
the Back Shoes. Hold in this position. Gradually
extend the Radius Die forward until the Gates start
to open and the Tubing begins to bend. Continue
bending until the bend depth is equal to that of the
master. (See gure 1-C)
8. Look at the Depth-of-Bend Plate or observe the DIE
ANGLE window. This is the depth or degrees of the
first bend. Record this information in the BEND
DEPTH section.
9. Retract the Bending Dies and slide the straight Tubing
to the left. Place the Tubing or master on top of the
Back Shoes so that the centerline of the second end
lines up with the centerline of the Back Gates. Be
sure that the master lies perfectly at.
10. Line up the second bend of the new pipe with the
second bend of the master. Be sure that the master
remains flat on top of the Back Shoes. Advance the
radius die until the pusher block springs are
compressed and the Tubing is held securely. Make
any adjustments at this time. Your second bend is
now correctly located. (See figure 2-A)
