I believe you may be able to find the manual here. Documentation – Silhouet-Tone USA . If not you may have to call Silouet-tone directly.
I dont know your prior experience with electrolysis, so to make it clear: This is a machine made for professionals, so you should take some classes or at least read some books about how electrolysis epilation works. “The Blend Method” by Micheal Bono (RIP) is a pretty good start, along with the entirety of the Electrology Now youtube channel. Other youtube channels like Josefa M. REINA also have useful information (The bubble test & The egg white test seem relevant for your new machine). If you look at the most recently updated thread on the home page you can see the consequences of mistreating skin. Be careful, and search stuff on this forum! There are TONS of helpful decade old threads.
