Modes of Operation
Indications and Alarms in Different Modes
The handheld milling cutter can operate in two equivalent modes:
Manual mode
Program mode
For each of the modes, each type of indication is shown at the display
by means of a relevant combination of characters, digits, and
segments, and is also backed up by specific audible signals
In any mode, prior to switching on the tool rotation, its direction is
shown by an arrow on the Display.
If the arrow goes upwards
and to the right, the tool
will rotate clockwise.
If the arrow goes downwards
and to the left, it means that
the "Reverse" function is
activated and the tool will
rotate counterclockwise.
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
