4. Operation
After setting the material to be bend between rollers, drive the leading roller by hand in the bending direction.
The desired profile bending is obtained by turning the upright driving shaft of the slide way gradually as well as
the position of the main roller shaft. The guiding rollers are driven by the bending mechanism activated by the
electric motor. It allows repeated travels in both directions. Starting of the electric motor in both directions is
possible by using the double pedal.
5. Labour protection rules
- For your own safety, disconnect the machine from the power source before maintaining or repairing it.
- It is forbidden to intervene to the gears during operation. They are protected by guards.
- Clothing and the tools you use for interventions have to be proper for the work you make.
- Check the fastening of the bending rollers on the shafts before starting the machine.
- Do not use pinched or cracked bending rollers.
6. Maintenance
Clean, grease and make the necessary adjustments before each operation. Check the temperature of the
bearings (touching them by hand) during operation. The temperature must not exceed 50˚.

8.2 Operation instructions
After the machine is assembled and fixed in place, perform the actions below in the order prescribed:
- Check if all metallic parts of machine are well earthened, according to the electric diagram. Checking is
made visually for the beginning, and then use an ohmmeter to measure the resistance of earthling circuit.
Inside, the earthlings must have a resistance of < 0,4 Ω.

-14-
- Check condition of electric instruments, junction wires, cables and electrical connections.
- After everything has been checked, connect the machine to the mains:
Supply is made respecting all conditions in §1.
In order to protect the feed circuit it is recommended to equip the power unit with fusible:3 x 10A for the 3
phases (L1, L2, L3); or to equip the power unit with an automatic switch 3P + N with Ir = 2.5A.
- Check if machine is correctly supplied after it is connected to the mains.
- After all checkings are made and machine is connected to the mains, start the machine on idle running in
order to determine the correct sense of rotation of the roller: when pushing the pedal on the right side, the
motor urns to the right and when pushing the left pedal, it turns left.
- Leave the machine on idle running for one hour. Meanwhile, check for abnormal noises of the electric
motor of overheating of the electric motor or electric instruments.
- Start the machine under lead and repeat all checking mentioned above.
8.3 Operation of the electric equipment
In order to start the machine, turn the QS power switch, which is to be found on machine frame, to the “I”
position (shut):
Positions of QS:
“O”- machine: uncoupled
“T” –machine: coupled
Push the right pedal for starting with the sense of direction to the right. The pedal acts the SB2 micro switch
making its contact; it controls connection of K1 contractor which supplies the M motor. The motors starts and
turns right.
Push the left pedal for starting with the sense of direction to the left. The pedal acts the SB3 micro switch
making its contact; it controls connection of K2 contractor which supplies the M motor. The motors starts and
turns left.
When the pedals are not pushed, the contact of the micro switch (SB2 or SB3) opens, the contractor (K1 or
K2) turns off and the M motor stops. The motor runs as long as one of the pedals is pushed. Machine is
equipped with SB1 stop button, which can be used for emergency situations or when repairs, adjustments etc.
take place. After the SB1 stop button was pushed, it is necessary to pull it out when you want to restart the
machine because it is a retaining button and therefore will stay pushed.
8.4 Maintenance and repair of electric installation
8.4.1 TROUBLESHOOTING
In case all those indicated at the previous chapters were respected and machine does not start when pressing
one of the paddles and K contractor (K1 or K2) does not connect, make the following operations:
- Check if machine is correctly supplied: 3 – 50Hz; 400V.
- Check if thermal protection of M motor (FR thermal relay) was activated and look for the cause which
determinate it. Reasons could be:
• Supply of M electric motor is made only on two phases or with lower voltage than 360V/50Hz.
• Thermal relay is not correctly set – at 2.3A.
• M electric is locked or turns hardly because of frictions;
• FR thermal relay out of order
Make corrections and reset the thermal relay with the help of resetting lever.
- Check the fusible: F2 in transformer primary circuit and F3 in the control circuit. In case one of the fuses is
broken, remove the fault and replace the fuse.
Attention! Use only calibrated replacing pieces with the parameters indicated.
- Check if the T transformer for 24V supply voltage of the control circuit is in working order:
• Check if T transformer is fed correctly in primary with a 400 V voltage;
• Check if in secondary the transformer supplies the 24 V voltage;
- Check if the control circuit has continuity:
• Tighten screws of the connections.
• Contacts of instruments (SB1, SB2, SB3 FR) in the control circuit to close correctly.
- Check if K contractor is in working order.
If pressing the pedal, the contractor makes a connection, but the M electric motor does not start, there could
be two situations.
- If M motor is correctly fed from 3-50Hz, 400V voltage.
• Check if the electric motor is in working order: stator winding not to be broken, connections at the
terminal box to be perfect etc.

-15-
• If M motor is not correctly fed from 3-50Hz; 400V voltage, check motor force circuit:
- Check the F1 fuse in the motor force circuit. In case one of the fuses is broken, make the necessary
repairs and replace the fuse.
ATTENTION!! Use only calibrated replacing pieces with the parameters indicated.
- Check if electric stress circuit of the FR thermal relay is not broken.
- Check if all junction wires and cable of electric stress circuit are not broken.
All necessary checks can be made with a general instrument (multimeter) which measures V,A.
8.5 Maintenance
Weekly checking:
- Make visual checking of electric apparent condition and in case they are damaged replace them with
others with the same parameters;
- Tighten the screws of electric connections and the holding screws of electric apparent;
- Check condition of feeder cable; jack and connecting socket to the mains and in case they are damaged,
replace them with others with the same parameters;
- Check if earthling circuit has continuity and its ohms resistance;
- Wipe the dust on the electric apparent and connecting elements. Use a soft brush.
8.6 Labour protection rules
- Respect all instructions and norms in force when mount, put into service, repair and maintain the electric
installation.
- Stop the machine and release it from the mains before any intervention to the electric installation or before
periodical checking of electric equipment and motor.
- All operations which ask the electric installation under voltage (measuring the energy, voltage, determining
succession of phases) will be effected only by skilled people with legal authority. They must have proper
tools equipped with non-conducting handles and non-conductive protection equipment.
It is forbidden to make any modifications to the electric installation. This could lead to dangerous
situations.
8.6.1 MEASURES TO PROTECT PEOPLE AGAINST ELECTRIC SHOCK
- All active metallic parts are inside cases. In this way people are protected against danger, which occurs by
touching the parts directly, according to EN 60204 §6.2.1.
- All active metallic parts are insulted against inactive metallic parts which the people could come in touch
