Reposting this for guys having trouble - especially with a Macintosh computer, where the software will not load, but individual files can be accessed:
Open 'STIHL' folder.
Open 'SCS 01-2010' folder.
Open 'Resources' folder.
Scroll down 2/3 of the way to find PDF files marked 'RA-xxxxx' (service manuals) and 'TI-xxxx' (technical information).
Open these with Adobe Acrobat, or something similar.
