To turn on the Nutribullet, attach the blade to the cup. Flip the cup and blade over onto the Nutribullet base, then twist the cup counter-clockwise to start the blending. Untwist it clockwise to stop the blending.
The Nutribullet uses high powered blades to make smooth drinks with any ingredient. There are several safety precautions to consider. Overfilling the Nutribullet can potentially cause it to leak. When attaching the cup to the Nutribullet, ensure you twist it counter-clockwise tightly. Because the Nutribullet uses no power button and only operates by twisting and untwisting it, never leave the machine running unattended. Most blending takes 1 minute.
