Unfortunately, the original looks like it's printed on cheap toilet paper and is unreadable because the font is too small.
I've scanned the original manual and used some decent software to enhance the images.
It's not brilliant, but better than the original and being A4 pages, can be printed and used until someone at the company provides a pdf for download.
It's 12MB and can't be reduced without losing resolution, as the original is piss-poor.
Hope it's of use to some of you.
