Manuals I've scanned are in PDF format. Offsite manuals may be in other formats.
I have a few items listed which have no link. That means I plan to add it but it's not yet scanned. Feel free to contact me and ask for it. Also please let me know if you have any problems, broken links, wrong files downloaded, etc.
Right click on the link and choose "Save Target As..." (or whatever your browser says). If you just click on it, it may try to open. Many of these pdfs are very large.
