I found this site and it has proven to have just about any info I have looked for. Most recently downloaded was the factory Husqvarna 50 page shop manual for their 350 chainsaw. Had all information from special tools needed, specks, expanded view and anything you would need for the repair of the entire saw.
You have to sign up but no fees. There may be more of these sites. If you have one let me in on it. This manual was from $5.00 to $30.00 on disc or download plus shipping when I started the hunt.
