Re: Legality of sending/ posting service manuals
Regardless of if someone else has done it, or published it before, unless YOU have written permission from the copywrite owner, you may not disseminate copyrighted materials. It has nothing to do with you making a profit or not. That is simply the legal answer.
Even IF a manufacturer of a product offers service manuals for free on THEIR website, you DO NOT have the right to copy those pages and repost them or distribute them ( if any page or the website has the familiar C with a circle around it). You may, however provide a link to THEIR website.
With all of that said, most people break one law or another on a daily basis. If you have ever driven 70 MPH in a 65 zone....you broke the law. Some "transgressions" are more tolerated than others.
