TRANSPORTING AND LIFTING
Follow these guidelines when lifting:
•The lift truck must be able to lift at least 1.5 – 2 times the machines gross weight.
•Make sure the machine is balanced. While transporting, avoid rough or jerky motion, and
maintain a safe clearance zone around the transport area.
•Use a fork lift with sufficient lifting capacity and forks that are long enough to reach the
complete width of the machine.
•Remove the securing bolts that attach the machine to the pallet.
•Approaching the machine from the side, lift the machine on the frame taking care that there
are no cables or pipes in the area of the forks.
•Move the machine to the required position and lower gently to the floor.
•Level the machine so that all the supporting feet are taking the weight of the machine and no
rocking is taking place.
INSTALLATION
IMPORTANT:
Consider the following when looking for a suitable location to place the machine:
•Overall weight of the machine.
•Weight of material being processed.
•Sizes of material to be processed through the machine.
•Space needed for auxiliary stands, work tables, or other machinery.
•Clearance from walls and other obstacles.
•Maintain an adequate working area around the machine for safety.
•Have the work area well illuminated with proper lighting.
CAUTION:Lifting and carrying operations should be carried out by skilled
workers, such as a truck operator. Make sure the machine is well balanced. Choose a
location that will keep the machine free from vibration and dust from other machinery.
Keep in mind that having a large clearance area around the machine is important for
safe and efficient working conditions.

•Keep the floor free of oil and make sure it is not slippery.
•Remove scrap and waste materials regularly, and make sure the work area is free from
obstructing objects.
•If long lengths of material are to be fed into the machine, make sure that they will not extend
into any aisles.
•LEVELING: The machine should be sited on a level, concrete floor. For stationary machines,
provisions for securing it should be in position prior to placing the machine. The accuracy of
any machine depends on the precise placement of it to the mounting surface.
•FLOOR: This tool distributes a large amount of weight over a small area. Make certain that
the floor is capable of supporting the weight of the machine, work stock, and the operator.
The floor should also be a level surface. If the unit wobbles or rocks once in place, be sure to
eliminate by using shims.
•WORKING CLEARANCES: Take into consideration the size of the material to be
processed. Make sure that you allow enough space for you to operate the machine freely.
•POWER SUPPLY PLACEMENT: The power supply should be located close enough to the
machine so that the power cord is not in an area where it would cause a tripping hazard. Be
sure to observe all electrical codes if installing new circuits and/or outlets.
ASSEMBLY AND SET UP
1. Remove the machine from the skid it was shipped on and install the casters and wheels.
2. Check the oil level and top off if necessary.
3. Read through the remainder of the manual and become familiar with the die installation and
settings as well as normal operation.
4. Position the machine as desired following the installation guidelines.

GENERAL DESIGN DESCRIPTION
You have made a practical choice in purchasing the RDB-175 Hydraulic Bending Machine. It
has been carefully built of high quality materials and designed to give many years of efficient
service. The simplicity of design and minimum effort required to operate the machine contributes
towards meeting schedules and producing greater profits.
The RDB-175 is an electric powered hydraulically operated “Rotary Draw” bending machine. To
bend material, a bending die and counter die are required. The material is hooked by the
bending dies’ hook arm and is powerfully rotated in the clockwise direction. As the bending die
rotates, the counter die arm also rotates about the same axis, forcing the material to conform to
the radius and shape of the bending die.
The RDB-175 Bending Machine you have purchased is built of solid steel ensuring maximum
rigidity. Tongue and groove design with grade 8 bolts throughout provides very high rigidity and
stability.
Throughout this manual are listed various safety-related descriptions for attention. These
matters for attention contain the essential information to the operators while operating, and
maintaining. Failure to follow these instructions may result in great damage to the machine or
injury to the operator.

ELECTRICAL
Motor Specifications
Your tool iswired for 240volt, 50Hz alternating current. Before connecting the tool to the
power source, make sure the machine is cut off from power source.
Considerations
•Observe local electrical codes when connecting the machine.
•The circuit should be protected with a time delay fuse or circuit breaker with a amperage
rating slightly higher than the full load current of machine.
•A separate electrical circuit should be used for your tools. Before connecting the motor to the
power line, make sure the switch is in the “OFF” position and be sure that the electric current
is of the same characteristics as indicated on the tool.
•All line connections should make good contact. Running on low voltage will damage the
motor.
•In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
CAUTION: HAVE ELECTRICAL UTILITIES CONNECTED TO MACHINE BY
A CERTIFIED ELECTRICIAN!
Check if the available power supply is the same as listed on the machine nameplate.
WARNING: Make sure the grounding wire (green) is properly connected
to avoid electric shock. DO NOT switch the position of the green grounding wire if any
electrical plug wires are switched during hookup.
WARNING: In all cases, make certain the receptacle in question is
properly grounded. If you are not sure, have a qualified electrician check the
receptacle.

14

•Improper connection of the equipment-grounding conductor can result in risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.
•Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.
•Repair or replace damaged or worn cord immediately.

OPERATION
Dry Running Machine
Before actually bending, several “dry runs” should be performed. This will remove any trapped
air from the cylinders and hoses. Also, this will familiarize you with the controls and functions of
the machine. To do this, set a bend angle and then activate the hydraulics to extend and retract
the cylinders to simulate a bend.
Setting Bend Angle
1. Reverse machine until both cylinders are fully retracted.
2. Set the digital controller to “0” by pressing the “F1/RST (reset)
button. The lower green number is preset position and the top
red number is the machine position.
3. In order for the machine to function the digital control needs to
have a stop point programmed for more than 5 degrees.
4. Press the “Right/Down” arrow key to activate the lower preset
degree field. Pressing the “Right/Down” arrow key will highlight
each digit field. The digit field will slowly blink when highlighted.
Machine will only bend to 200 degrees. The cylinders will
deadhead when the reach full extension.
5. When the digit is highlighted, press the “UP” arrow key to change
to the desired digit in that field.
6. When the desired bend degree is entered, press the “Circle”
button to save. The machine will now stop at this preset degree.
CAUTION: Always wear proper eye protection with side shields, safety
footwear, and leather gloves to protect from burrs and sharp edges.
CAUTION: Keep hands and fingers clear of the dies and swing arms. Stand
to the front of the machine to avoid getting hit with the material during the bending
process. When handling large heavy materials make sure they are properly supported.

16
16
7. The digital control and preset should only be used in whole
degrees. For example 90, 91, 92 not 90.1 or 90.5. If any number
is entered after the decimal the control will add 1 to the final
degree. So it’s best to leave it at 0.
8. If you want to compensate for spring back the “0” position can
be set anywhere.
a. For example: Take a piece of material and insert it into
the die and close the counter die.
b. Activate the FWD pedal until the material just starts to
bend.
c. Set your “0” point here and that should compensate for
most of your spring back.
d. Now the preset value can be entered exactly to the
desired degree + / ‐.
9. Another way is to “Add on” spring back values to the preset.
a. To do this set your “0” position with the cylinders fully
retracted.
b. Insert material and bend a part to exactly 90° using a
framing square.
c. When still at the final position. Document the actual machine position.
d. For example: If the control reads 105° take 105‐90 = 15° (90 deg being your desired
bend angle). This will be the value you will add to your nominal degree setting when
entering preset values.
10.There is no right or wrong way to use this control. It is purely the user’s preference.
Home position with 90° Preset Stop Point. Stop position with 90° Preset Stop Point.

17
17
DIE SELECTION AND INSTALLATION
Before any bending can take place, the
proper die set must be chosen to match the
material being bent. (EX) 1-1/2” diameter
tubing requires a die set marked 1-1/2”
tube.
A Hook Arm
B Bend Die
C Hold down Bolts
D Plastic Slide
E Counter Die Mount
F Bronze Counter Die Insert
G “0” Mark
Note: Pipe and Tube are not
the same, (see table 1) for nominal pipe
sizes. All RMD dies are color coded to
avoid confusion between pipe and tube
(see table 2).
IMPORTANT: Damaged or worn
tooling should be replaced before
attempting to bend material. This will
ensure that bends are correct and provide a longer life to machine components.
When handling large heavy dies and/or material, make sure it is properly lifted and supported.
1. To install the die, slip the die over the centering pin until the three unequally spaced drive
pins engage the receiving holes formed in the die.
Note: The die will only fit one way.
2. When the drive pins line up the die will drop all the way down to the spindle.
3. Install and tighten the 1/2-13 socket head bolts provided with the die. Tighten these bolts
enough to hold the die firmly down to the spindle. Approximately 30-40ft-lb. (40-50N•m).
IMPORTANT: FAILURE TO PROPERLY BOLT DOWN DIE WILL RESULT IN
DAMAGE TO MACHINE AND TOOLING.
