If it's an operaters manual you can download it from Stihl's web site .
They aren't quite as generous with shop manuals or IPL's though because they are of the mindset that that it takes a genuine factory trained Stihl gold level mechanic to work on their precious saws .

Of course they won't admit it but they are wrong .

I have the shop manual but it like so many others I have is on micro fitche and I have no way to transcribe it to computer usable text .
Every so often one pops up on E-bay though if that helps .
