Do you have air to the machine.
Do you have a air gauge in the back of the machine that says zero?
Have someone press the button and see if it is pulling a solenoid in the back.
Check all the fuses, might have been disabled in another life?
Do you have a ladder diagram for M 06?
Do you have a wiring diagram for the front panel?
Sorry, I guess I have more questions for you than I have answers.
Maybe a diagram for the air lines. Can't spell pneumatic.
