Looking for a user information, For a SATO R3 Hardness Tester

This Chinese tool has limited information online.

Try checking this site : http://bandsawmanuals.com/search?manufacturer=Rockwell . They have free manuals for bandsaws.

hey there i just bought a used 215 7-
1/4" saw it came w/ a manuel
maybe i could copy it for u and send it to you [email protected]

I can't find one for the exact model number you have, but there are a lot of manuals for the same era bandsaws available as PDF downloads at this site. Perhaps another manual for a similar machine will help answer most of your questions, in lieu of the correct one...
Have a look around there, though, at both the Delta and Rockwell listings, as I just made a quick look to find yours and there might be something there somewhere.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

The manual doesn't seem to be available online at the moment. There's a parts diagram, if that's helpful, or perhaps you can find an alternate site that provides instruction manuals. See this link, in any event.
Otherwise, you might check Woodworker's supply (woodworker.com) for the accessory fence and rail. They carry genuine Delta parts, which should fit your old Rockwell, as well as some aftermarket fences and guides that will usually adapt easily to fit a 14" bandsaw. The 14" Rockwell is one of the industry standards, and many woodworker catalogs carry fences that will bolt on with a minimum of fuss.
I recommend you do a web search on "14" bandsaw fence", and browse the results. You may even find something used to suit your needs.
Good luck, and let us know if this solves your problem or we can provide any further information!
