What do you need to be done?
The SAA is pretty simple to work on and if you have to have it in print, get Kuhnhausen's book.
Just use the correct screwdrivers and carefully disassemble the piece, then more carefully, stone away any burring or high spots.
Following that, make certain it's 'clean', then apply a touch of grease on the bearing points (I use Pro-Shot's 'Pro-Gold'), lubricate with well-shaken BreakFree, reassemble, and try.
