La vitesse de transmission est de 50 bauds , soit 7 caracteres par 
Seconde. On utilise le code baudot a 5 moments.
Cette machine a ete etudiee en 1944,
145 machines sont fabriquees en 1945
a l'epoque le transistor n'existait pas , tout le codage et le 
decodage des caracteres est fait en mecanique.
Elles ont supporte tout le trafic des agences de presse,
des messageries d'entreprises, des stations meteorologiques.
Cette machine provient d'un bateau de la marine nationale, 
la transmission se faisait par un emetteur/recepteur radio a 
tubes a vide.

> I would like to know what solution exist to make it alive.

The above video from someone only known as f5zj is proof that it can be done!

> I have begin the cleaning of the Teletype.

That is the correct first step.

> I try to not unscrew anything because i am scary to unadjust the machine.

It helps to take photos of everything before you unscrew anything.  Put any screw or other part you remove in an envelope, index that envelope to a clear photo of the place it was removed from, and number the envelopes in the order the parts were removed.  This way, you can re-assemble the machine by reversing the order of disassembly, and the envelopes make it much harder to lose anything.  For large parts that don't fit in an envelope, tie a label to the part with the same information you would have written on the envelope.

Bonne chance!
