1.9.3 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.
1.9.4 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.
