I havn't worked with the exact motor you have, but I've tinkered with a
similar one. Hope this helps.

These guys look like a (from a circuit-sense) as :


AC line -----------*------ switch --| |-----
		   |                        |
                 Stator                   Start
		 Coil                     Coil
		   |                        |
		   |                        |
AC line -----------*-------------------------


The switch is closed when the RPM is low (~75% rated speed). The direction of
rotation is determined at power-on. If you disconnect the starter winding, you
can manually start a motor in either direction. Better yet, just switch the
'polarity' of the stator winding with respect to the start winding to reverse
the direction.

To get your motor to run:

	Connect terminal 2 to AC line.
	Connect terminal V to terminal 1
	Connect terminal 4 to AC neutral
	Connect terminal 1 to AC neutral

To reverse direction, interchange 1 and 3.
