Taurus type vc 40w fan wiring

Hi , 
I would like to find manual service menu or How to repair list of the fun Taurus s.a. type vc 40w.
This fan is old at least 30 years and it is not working because from 3 wires going from the motor to the switch, two of them are not attached .
I do not know the exact points where to attach it properly so, i need schema - service, repair manual for the fan.
