Emergency-stop push button
ATTENTION!
If a emergency-stop push button is activated, the drives are stopped with the maximum
possible braking torque. The spindle drive continues to run for a while depending on the
moment of inertia of all components and the mass of the tool in use.
Press the emergency stop button only if there is a risk! If this push button is actuated in
order to switch off the milling machine in the standard operation the tool or workpiece
might get damaged.
After having actuated the emergency-stop mushroom switch, turn the knob of the particular
push button to the right in order to restart the machine.

Control technical protection
WARNING!
If you bypass a controller you endanger yourself and other persons working on the
milling machine.
injuries due to tools, workpieces or fragments hereof which are flying off at high
speed,
contact with rotating parts,
fatal electrocution,
pulling-in of clothes.
If you temporarily bypass a controller in exceptional cases (e.g. during electrical repairs), you
must continuously monitor the milling machine.

Polycarbonate windows
Polycarbonate inspection windows, which have a safety-critical protective function in respect of
flying parts, must be visually inspected at regular intervals by responsible personnel provided
by the customer in order to guarantee the operational safety of the milling machine.
Polycarbonate viewing panes are subject to an ageing process and are classified as wear
parts.
The ageing of polycarbonate windows can not be detected by visual inspection. It is therefore
necessary to replace the polycarbonate windows after a certain time.
Prolonged exposure from polycarbonate windows to cutting fluids can lead to accelerated
ageing, i.e. deterioration of the mechanical properties (brittleness). Coolant vapours, deter-
gents, greases and oils or other corrosive substances from the operator side can also lead to a
deterioration of the polycarbonate windows. The result in reduced impact resistance of the poly-
carbonate windows.
