How to change the blade in your NutriBullet 900 Series
Watch the guide or follow the steps.
- 1Unplug the motor base and wait for the blades to stop before you lift the cup off.
- 2Turn the cup upright and unscrew the old blade. The blades are sharp: hold the blade by its plastic base.
- 3Check the gasket is seated all the way round inside the new blade. Don't pull it out: NutriBullet says removing it damages the blade and causes leaks.
- 4Fill the cup no higher than the MAX line, screw the new blade on and twist until it is tightly sealed, then turn the cup over and push and twist it onto the motor base.
- 5Wash the blade by hand in lukewarm water, not in the dishwasher, and dry it on its side.
