I have put this up before but it has been a while so here it is again:Įvery Stihl model is part of a series that gets assigned a series number when it goes into the R & D phase and if it makes it to production. Again Im sorry for not knowing the name of author. I would love to give credit to the author of this but I cant remember members name. I found this seaching for something else and saved it on my computer. Cant remember who origanlly posted it so I wont take credit.
