The Speedy Share links work fine for me, but I have decided to mirror the manuals on my personal webspace.
You can get the v3.1 Imperial Manual here:

And, you can get the v3.1 Metric Manual here:

I would prefer that you use the Speedy Share links (if you can) to minimize my webspace download traffic and so that I can track the number of downloads.
