Ⅰ. About the Product:
This Tube bending machine is a motor-driven tool set for special
purposes, can make adjustments to workpiece holdings either
mechanically or hydraulically. By utilizing the metal materials’ adaptable
distortion, the tool can bend workpieces such as low-carbon and
stainless round tubes, square tubes, steel angles, I-shaped steel stripes
and round steel bars to achieve your desired shapes. Being
indispensable equipment for construction and beautification works today,
can be widely used in the field of building construction, decoration
industry, furniture building and garden construction.
The equipment features “one-touch” operation on single workpiece
and data-program controlled mass processing. Being easy to operate,
reasonable in composition, and low power consumption with high work
efficiency, the equipment is ideal for bending metal pipes.

infused to the marked parts of gear box and the required level of
lubricant is satisfied.
(4) For machine with hydraulic power, ordinary hydraulic oil YA-N46
maybe added into it’s hydraulic oil tank and make sure that the amount
of the oil reaches the marked level. The first oil infusion may go beyond
such marked level.
(5) Turn AUTO/MANUAL knob to MANUAL, press Forward spot-turn
button to make sure that main shaft is moving clockwise.
(6) Press EMG STOP button in times of mounting or dismounting dies to
stop the running shaft. Never mount or dismount a die until the main
shaft comes to full stop.
(7) Keep away from the main shaft and dies when machine is working.
(8) Make sure that the machine is disconnected from power before
cleaning or checking the machine.
(9) The machine has been well tested for trial before delivery. Please
simply secure your machine on a smooth, plain surface.
(10) Cleaning: Make sure that each part of the machine is in normal
condition, removing any obstacles nearby to ensure proper operation of
the machine.
(11) Wirings can be conducted exclusively by professionals to ensure
sound grounding.
(12) Always identify and use the right bending dies in accordance with
the specifications of the work-pieces that you desire. Never force your
6
machine to do work beyond its capacity.
Ⅳ. Operation:
(1) Clamp: Work at Manual mode, press on this button to clamp the
workpiece.
(2) Loosen: Work at Manual mode, press on this button to loosen the
workpiece.
(3) Pump Indicator: when pump start, Light flash.
(4) Pump Start: Press on this button to start pump.
(5) Auto/ Manual: Select Auto mode or Manual mode for bending.
(6) Forward spot-turn: Work at Manual mode, press on this button to
forward bending
(7) Reverse Spot-turn: Work at Manual mode, press on this button to
counterclockwise bending.
(8) Power: When start main power switch, Light flash.
(9) Stop: Press on this button to cut off power supply.

1. Preparation before bending
(1) Choose the proper dies for the material you are to work on, and
assemble the dies on the machine.
(2) Adjust limited switch according to dies size, to make sure that the #2
Rear dies can press the workpiece at the proper point.
(3) Trial operation is advised. Connect the machine with power supply
(the power indicator now lights up), activate the oil pump power supply
to turn on the hydraulic oil pump.
(4) Select Manual or Auto mode, start bending.
2. Manual Mode
(1) Turn the knob to MANUAL.
(2) Place the workpiece into the die groove and fasten it by #20 Pipe
Clamp.
(3) Press Clamp button to make the sliding block moves to the set point
and make sure workpiece be clamped tighten.
(4) Press Forward spot-turn button to make the reversing valve lever
rotary forward so that the hydraulic rod and pressing wheel can squeeze
the workpiece to the desired degree of bending.
(5) Press Reverse Spot-turn button to make the reversing valve lever
rotary reversed.
(6) Press Loosen button to make the sliding block moves backward.
(7) Take off workpiece.
Note: At manual mode, angle setting function is invalid.
8
3. Auto Mode
(1) Turn the knob to AUTO.
(2) Place the workpiece into the die groove and fasten it by #20 Pipe
Clamp.
(3) Set the proper angle want to bend (0-180º).
(4) Step on the pedal and the machine will perform fastening, arc
bending and repositioning automatically. Make sure that the machine
works properly by repeating the steps before bending the workpieces.
(5) Take off workpiece.
Ⅴ. Set Counter
PV: Actual bending angle
SV: Required bending angle
(1) The required angle can be defined by the counter. E.g. if the bending
angle is required to be 90º, then the counter should be set up to 90º.
(2) Press the Forward spot-turn button (or step on the foot-pedal) until
the desired angle where it’ll stop automatically and the task
completed.
The way to set counter:
1. Press “set” for one second, and then setting value SV is flickering.
2. now press＜to set multiple, when you adjust the multiple you want,
then the digit is flickering.
3. Press ∨∧adjust the size of the number.
9
4. Press “set” for one second again, quit adjust mode. Then setting value
SV is stopped flicker. Setting is finished.
Note: 1. if you press “set” for three seconds carelessly into adjusting
counter mode; please don’t change the number anyway. Press “set”
continuously until SV shows 0000 correctly. Otherwise the counter can’t
work normally. Then use the last four steps to set counter.
2. “set” also has the function to back zero.
Ⅵ. Lubrication and Maintenance:
(1) Bearings of all axis must be lubricated with calcium grease on
6-month basis.
(2) Users are advised to check the condition of the electrical devices on
regular basis to ensure the soundness of such devices and ground
wires. Turn off the machine in the event of occurrence of any trouble
or abnormal sound. Disconnect the machine from the power source,
find out the trouble and eliminate it timely.
(3) Clean the machine after work and apply anti-rust oil onto the
unpainted parts of the machine, keep it in good condition.
(4) A good mastery of the operating sequence will avoid wrong
operations.
(5) Pay close attention to any damage caused to the adjustment disk.
Replace it if necessary to avoid personal injuries.
