Such signal may be caused by
mechanical or electrical faults
in the pedal itself as well as in its
power cable or control circuit.
For example:
1. Foreign items are on the pedal when it is powered up
2. The contacts in the pedal have stuck together and thus
always remain in the short-circuit position.
3. The pedal power cable has been worn out to the end, broken
down or destroyed
In order to fix the problem caused by such a signal, the following
steps must be taken:
1. Remove the foreign items from the surface of the pedal
2. Press the pedal a few times to check the mechanical
intactness of contacts
3. Disconnect the pedal from the power unit and continue
working without the pedal
A fault in the electronic components
of the power unit may cause such a
signal to go on.
In case such signal is on, the
following must be done:
1. Stop the operation
2. Unplug the milling cutter
3. Contact the Service Center

Work Sequence
Power Up
Attention!
When powered up, the milling cutter will maintain the
same operation mode and the same adjustments that were in effect
at the power down moment. There is no need to recall and set the
operation modes again. This memory is independent from any
operation mode.
Switch the power unit on, having set the power supply switch at the
back panel from the '
0
' position to the '
I
' position.
This will activate the self-test of the Milling Cutter and it will be
indicated in the form of 'running lights' at the LED Range and in the
form of 'running eights' at the Display. As the 'running eights' fade
away in combination with the 'running sequence of lights' and as a
single audible signal is heard, it tells us that the self-test is completed
and that the equipment is ready for work if the following conditions
are fulfilled:
1. The 'MULTIBOR' sign at the upper lid of the casing is
illuminated with constant blue light
2. No breakdown alarm is heard
3. No 'Pedal is out of order!' indication is shown at the Display
