Researched a bit more, it seems you have to buy RAR download.
I tried the free trial, but it limits how much you can download for free (which doesn't even cover one of the files!
I think it is probably easier and less time-consuming to buy the disc off Ebay......
If you don't have a rapidshare account (6€) for 30days then you can still download as a free user; you will just have to wait a short time for a download slot and you will not get maximum speed.
Download the links by just pasting it into your browser.
Once you have all four files open them with the free trial version of WinRAR and extract.
The reason I uploaded them to Rapidshare is becasue it is the most popular premium download service. Many many people do have rapidshare accounts (infact these manuals have been downloaded over 100 times)
