Malfunctioning, failure and breakdown
Following, the most common malfunctioning situations on the machines:
a) The machine cannot bend the maximum diameters as in the schedules:
• Check if the line voltage is over the tolerance 5%.
• Check if the diameter of the cable used to supply the machine is long enough to avoid any current
leakage.
• Check the transmission belting stretching and efficiency: they could split during the maximum effort of
the machine.
• Check if the bars strongness corresponds to the foreseen parameters according to the use limitations.
• Check the blades efficiency (only for combined machines). In case the blades are damaged, also just
in part, the machine can not cut the maximum diameter on the schedule.
b)
The machine stopped and it doesn’t start again:
• Check if the emergency buttons are not pushed.
• Check the position of the bending protection and its limit-switch.
• Check the position of the cutting protection and its limit-switch
• Check if the current reaches the electrical box.
• Check the pedal components.
c) The disc turns without stopping at the limit-switch signal:
• Check that the pin position is perfectly in the required hole.
• Check the two limit-switches: they could be damaged or simply moved.

Maintenance, inspections and checks
Our advice is to submit periodically the following checking:
11.1 Oil level:
Monthly check the oil level and add it in case the level is too low.
The complete oil substitution is recommended each 4.000 working hours, unloading all the spent oil in
the reducer unscrewing the unload cap. After the unload-cap cleaning, screw it and full the reducer
pouring the oil through the load cap in the quantity required by the indicated level using oil type

Belts:
Check tension and conditions of the driving belts.
The belts have to be always well tightened to avoid any slipping that might lead to a malfunction or a
quick wear of the belts themselves.
11.3 Blades replacing:
Check every 40 working hours the blades efficiency and replace them in case they are damaged.
For the blades replacement it is enough to unscrew the blades from the machine. For the unscrewing
of the mobile blade from the rod, the blade must stop totally outside the machine. To obtain this,
follow these instructions:
a) Check that there are no pins into the bending disc and that the machine working plate is empty from
all the fittings.
b) Turn the machine on, turning the main inverter-switch.
c) Push the reset button.
d) Push the pedal for the mobile blade exit and release it when the blade is completely outside.
e) Detach the machine tension.
f ) Replace the mobile blade.
