completely
Check the Electricity Board Cap
FAULT 2: If bending disk turning continuously
FAULT3: Motor protection switch is blowing continuously
If the machine is bending iron
over its bending capacity
Check the bent iron according to
the material type and
measurements on the capacity
plate
Missing phase might come to
the electric supply system
Check the phases on the electricity
network
Transformer might be blown
There might be short circuit or
wearing on the cables
Check the cable and connections

Motor's propeller cap might be
rubbing
Gears might be broken down
There might be no oil in the reducer
Missing phase might come to the
electric supply system which the
machine is connected.
Check the phases in the network
Machine might have difficulty over
its capacity.
Check the bent iron according to the
