PUSH BUTTONS
The buttons have a dual function: they can be used to
select machine functions or as numerical keys in the ser-
vice submenus.
They in fact feature an icon that represents their meaning
and a number for use as a numerical keypad.
An emergency STOP button is also available which, when
pressed, stops the motor and brings the machine to a
standstill.
The pressed position of the emergency STOP button is
represented on the display in position 7.
To make the machine operational again, the button must
be turned and released.
For the description of the individual functions, see para-
graph 6 Using the machine.
