5202. Some wheels are are constructed in such a way that rotation is important so when you see a rotation pointer you should abide by it. Wheels with not such and most wheels can go one way or the other with no problem. Also important that the wheel holding nut goes/turns in the tightening direction when you turn on the spindle/motor rotation.
