In the "0" position, the lockable main switch can be secured against accidental or non-author-
ised switching on by means of a padlock.
The power supply is cut off when the master switch is in the off position.
Except for the areas marked by the pictogram in the margin. In these areas there might be volt-
age, even if the main switch is switched-off.
WARNING!
Dangerous voltage even if the main switch is switched off.
The areas marked by the pictogram might contain live parts, even if the master switch is
switched off.

1.9.2 Emergency-stop push button

CAUTION!
Only press the emergency stop button in a genuine emergency. Do not use the
emergency stop button to stop the machine during normal operation.
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 push 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.
