Single phase induction motors, generally have a start winding and a run winding, the start winding may, or may not require a capacitor in series with the winding and some have a centrifugal switch that cut the start winding out as soon as it is up to run.
What you have to determine is what of the above category the motor falls in. As a Guess I would say that U1 U2 is the run winding and V1 V2 are the start winding.
Reversal is achieved by reversing either pair, before start up.
In the absence of any other info, I would measure the windings and see if there is a difference, resistance wise, the higher resistance being the run winding.
If a capacitor is not required, you could simply put the U windings In parallel with the V windings apply power momentarily and see if it runs, if it just hums then you probablly require a capacitor start.
If you were to give it a spin, it should go up to speed. But It would be advisable to put a clamp-on ampmeter on one line at all times just to monitor the current.
If it runs, you can usually hear the centrifugal switch operate, this cuts the high current start windings out, otherwise the motor would burn up.
Some induction motors are made without cap. start and with the start winding in circuit in run.
