Hi everyone,

Thanks for all the advice. I have been busy at work with other things so I couldn't read you posts since now.

Unfortunately I don't understand anything about what you said. I have never used the machine and I have been asked by my manager to fix it.

I think that the easiest way to deal with this would probably be to find someone that can come and have a look at it. Unfortunately I have no idea about who this person might be. Do I have to look for an electrician? A mechanic? Somebody that deals with these machine already?

Many Thanks for your help,

Valeria
