@Admin think this should be a sticky. All copied and pasted from this site.
The online manual is available to registered users at:
https://www.tritun.net/tritun/vehicle/lookupFormRegistration is free and the site is pay per use (can choose hour or day).
I managed to download the entire manual in under an hour by using an accelerator plugin for Firefox which is available at
https://addons.mozilla.org/en-US/firefox/addon/tritun-downloader/. Note that Firefox is required for this to work.
This will download the manual in HTML format and then convert it to a single PDF.
The downside of this is that there is no Contents page. So I added one using Javascript to generate it on the fly. You have to use the HTML version for this and it does take a while to load. I have saved a copy of the Javascript and instructions to make it work at
https://1drv.ms/u/s!AklN_n3oWflk7CYA_cgWuKqf7LIU. Suggest you make a copy of the HTML file and the directory containing the files (images) so you can start again if you get it wrong

There are still no hyperlinks within the document. I'm afraid you will have to add those manually if you want them or use search

(E.g. "See Tank Removal")
Here's a link to the original thread on the forum if you are bored.
