Found the problem!
Former owner installed RAM SIMM on Wrong slot...
Put the SIMM on first slot and drawbars works correctly.
Don't even needed to install O.S.
Thanks for your help.

Thanks for the answer.
I'll try to reload the O.S.
It's strange because all other functions works fine. Just drawbars going crazy! Lots of noise...
