Speaking of start-up, I should've mentioned that you should rotate the shaft
several times by hand after adding oil; some manuals or installation sheets
will mention this but others don't. It isn't good to just dump the oil in
and rely on the compressor to distribute it when you run it- don't ask me
how I know.
