Overview
The DSX 25 Spiral Bending Machine is designed and manufactured for spiral bending of round
and rigid metallic bar materials. All other purposes of use are not supported. This machine can
be operated for various shapes of bending. In order to get the best results from your DSX 25,
locate it in such a position so as to be operated easily, and to provide ample space around the
machine.
We recommend you to locate workbenches in both sides of the machine. The length of each
bench should equal the longest length of the rebar material to be bent.
Important Warning
• Prior to operate the machine read through this Operating & Maintenance Manual, carefully.
• Only the qualified personnel are allowed to operate the machine.
• Disconnect the power prior to make checks, maintenance, lubrication, and/or adjustments.
• Observe all guidelines provided in this Operating & Maintenance Manual.
1. SET-UP PROCEDURES
1.1 Level the machine on a flat and supported floor surface / ground (Figure 1).
1.2 Made the power connection by a qualified electrician.
Note: Power Connection
1.3 Plug on the power supply cord of 5x4 mm2 to the feeding line of main power.
1.4 Grounding is required. Do not operate the machine without grounded power.
Grounding Connection: Follow the procedure below. Connect one end of the ground cable to
a copper wire (minimum16 mm) so as to ensure electrical conductivity. The other end of the
Page 3
Rev 11/2/2020

cable is to be connected to a tube having ability of conductivity dipped sufficiently into the
ground (into the damp soil, preferably), or to a copper plate buried under the soil as deeper as
possible.
FIGURE 1
1.2. START UP PROCEDURE
1.2.1 Check and ensure that the machine is installed in accordance with instructions.
1.2.2 Remove all parts (including bending apparatus) from the top surface of the machine.
1.2.3 Turn the switch (LEFT/STOP/RIGHT) to the LEFT or RIGHT, and the switch (MANAUTO) to the MAN position, and determine the direction of rotation of the machine by pressing
the food pedal down.
Note: The clockwise rotation is accepted as the right rotation and the counter clockwise
rotation as the left from the front view (the control panel side) of the machine. If the machine
rotates counter clockwise in comparison to the turning direction of switch, it means that the
phases of power network are reverse. This situation will not create any problem for the
operation of machine. In such cases, you may turn the control switch (LEFT/STOP/RIGHT) to
the LEFT or RIGHT.
1.2.4 Start to make bending adjustments by following determination of rotation.

6. PROTECTIVE PRECAUTIONS
6.1 Protective Cloths
• Protective helmets
• Goggles
• Boots with steel heads.
• Gloves
Use the above protective material when you work on the machine. In case of not use these
protective materials note that there is always a risk of injury such as hand-cut and/or handcaught.
6.2. Working Garments
Note that the following are the things and garments not convenient to wear against the risk of
injury and caught during working with the machine: long hairs, dresses with long arms, identity
disks or jewellery, long working aprons etc.
7. TRANSPORTING
Utilize a forklift and/or a mobile, or a bridge-crane for transporting and lifting the machine. Use
forklifts only when the machine is in a container. Put the machine in a container using wooden
wedges under its wheels so as they do not touch on the bottom of a container, or locate it in a
container with its wheels disassembled. Use steel ropes, chains and/or polyester tackle-block
for lifting the machine. Use the lifting collets for crane hook to lift it without its container.
Employ experienced or specialized people or subcontractors for lifting purposes.
Warning!
Move the machine without causing any vibration. Do not transport it in wet conditions.
Please forward to the producer a report for the parts lost or damaged during transportation.
• Take maximum capacities of transportation and lifting machinery and equipment into your
consideration.
• Take the centre of gravity of the machine into consideration during lifting it.
Note: Observe all instructions written on the warning labels

8.1 Adjustment of thermal current field, and motor circuit breaker
It is ex-works adjusted by its manufacturer as 8.6 A for 1.5 -2.5 kW motor with 750 -1.500 rpm.
(Figure 15) Do not change this adjustment. The motor circuit breaker is installed onto the
machine to de-energize the motor in order the machine not to be damaged when it takes
excessive current. Turn the switch to the position (1) for re-starting the machine in case of
circuit breaking. Under no circumstances the circuit breaker is dismantled.
Note: Should the machine be stopped by pressing the emergency stop knob turn the
MAN/AUTO switch to the MAN position and the LEFT/STOP/RIGHT switch to the reverse of
direction in that moment, and then to the direction of arrow the Emergency Stop, and press the
foot pedal and pull the material compressed out of the machine.
8.2. Bending Adjustments
Turn the switch (MAN/AUTO) to the MAN position, close the shield and push the material to
the direction of arrow by pressing the foot pedal down. Make adjustments both in diameter and
in pitch by means of the adjustment bracket and the bending slope. Make the adjustment of
diameter by means of turning the adjustment bolt and moving the adjustment roller forward
and back (Figure 4) (Closer the adjustment roller to the fixed roller smaller the diameter (D) of
the material is, and vice versa). To adjust the pitch (t) among the spiral circles lift the bending
slope (SX 36-39) up and down by means of the bolt underneath (Figure 4). Lower the slope
smaller the pitch is, and vice versa. Following the adjustments required shift the machine in
AUTO position and start to make serial bending (Figure 6).
Note: The rollers of the machine continue to turn as long as the foot pedal is pressed down.
The rotation of rollers stop if the foot pedal is stopped pressing. The rollers start to turn if the
foot pedal is pressed one time whilst the machine is on AUTO position. Press one time again
onto the foot pedal to stop it again.
