  1. 1Unplug the motor base. When the blades stop, turn the cup anticlockwise and lift it off.
  2. 2Turn the cup upright and unscrew the old blade assembly. Hold it only by the outer edge of its base: the blades are sharp.
  3. 3Check the new blade assembly for bent or damaged blades before you use it.
  4. 4Fill the cup no higher than the MAX line, place the blade assembly on top and turn it clockwise to seal.
