Hi Wdt,
The UP-4 is a unipivot, which means the the arm is supported entirely on a single, sharp point resting in a small cup (or possibly the reverse). There is no lateral support of any kind. That would defeat the intention of the design, which is to eliminate bearing friction.
All unipivots rotate about the axis of the armtube when torqued rotationally, as by lifting with the finger lift. This is normal but it does take some getting used to.
The critical thing is that the stylus be vertical when riding in the record groove. This adjustment is called "azimuth". On a UP-4 I believe this is accomplished by rotating one of the counterweights. Hopefully there are instructions for this in the manual.
