You firstly need to extract the pdf document from the .RAR file (like a zip).
Use WinRAR to unpack the file you download from my site:
http://www.win-rar.com/index.php?aid...0e1b07ac4a276b
A Mac version is on that site so your should be fine.
Then you will have the .pdf file. Use Adobe Acrobat to read this:
