Tips on Operating Your NSD Spinner
No battery required; Just like riding a bike! Your hand is the battery of this device. The motion of your hand rotating the Spinner is similar to making ice cubes swirl inside a glass. The essence of operating the Spinner is not about how fast you rotate your wrist. It’s about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor’s gyration. The faster the rotor spins, the easier it is to operate. Make sure you start the Spinner with sufficient speed.
Maintenance
Keep your Spinner from dusty environments. Don’t put your Spinner on the carpet or any fabrics. Dust may be brought into the internal surface of the shell by the rotor and make the inner tracks dirty. Eventually it would make noise as the rotor spins.
Wash your hands before using the Spinner. Sweat or lotion on your hands will decrease the capability of speeding up the Spinner's RPM. The Speed is increased by the friction between the spinning rotor and the inner tracks. Never lubricate your Spinner. Oil is the killer of its friction.
Clean your Spinner periodically. To clean the Spinner, take off the rubber band, unscrew the shells with a precision screwdriver, insert a coin into the gap between the upper and lower shells and then twist the coin to open the shells. Once you disassemble the Spinner, (remove the digital counter first if your model is equipped with it) use water Only to clean the tracks and shells and then dry the parts before re-assembling. For PB-688 series models, you may also reverse the two inner tracks to make your Spinner spin as smoothly as new.
