It is easy to adjust the height of the beater on a KitchenAid tilt head mixer.  This is often necessary if the beater is too high or scrapes the bottom of the bowl.  The head should be adjusted to ensure that the beater is just above the base of the bowl.  If it scrapes then the coating of the beater will wear off and be deposited into the food being mixed.  

  1. Unplug mixer
  2. Tilt head on mixer back
  3. Turn right (clockwise) to lower beater, turn left (anticlockwise) to raise beater.
  4. Lower head to check clearance
