Chris,
The most important item is
do not turn the speed dial when turned off. That can damage it. Good news is there are parts for virtually every repair if you have problems. My SS is a 1954 model, and I can still get parts from Shopsmith, as well as used.
In general, if you are handy with a wrench and screwdriver, it all comes apart and goes together very simply. I am sure others will add some more specifics, but there are no "tricks" or surprise springs, hidden fasteners, etc. Don't forget to bring Hex keys (aka Allen Wrenches) to take it apart. All of the fasteners are in SAE sizes 3/16", 1/2", etc. (non- metric).
Please see the "Newowner Information" thread under Maintenance and repair for a lot of info to get started. Link here:
