Toys Heart is literally warning you that there is a special way to use the Kaiten Chui Spinning Onahole. ("Kaiten Chui" translates as "careful how you spin (this)".) The reason is 99 short, blunt-tipped pyramids line the entirety of the hole, making it difficult to manipulate if you do it incorrectly. So while you might want to attach to a fan or another high-powered device to really give it some speed, Toys Heart warns against this.
The proper way of engaging with this beauty's transparent body is to lube up the vagina-shaped labia, plunge inside, and place it between your two palms, moving her back and forth alternatively (as if you were creating a fire with sticks). That said, you may also use her in the more traditional "piston" style as well. Designed especially for those who love the super tight feel of a virgin, this gal is also smaller than most onaholes, so she makes contact with only the most sensitive part of your penis.
