Attachment Hub

• 1). Check that your KitchenAid stand mixer speed control is set to "Off/0" and that the mixer is unplugged.
  
  
• 2). Turn the attachment knob that is beside the power hub counterclockwise to loosen. Depending on the model stand mixer, remove or flip up the hub attachment cover.
  
  
• 3). Insert the attachment power shaft into the attachment hub on the stand mixer. Both the internal part of the attachment hub as well as the attachment power shaft are square in shape. If the two are aligned improperly the attachment power shaft will not fit into the attachment hub.
  
  
• 4). Check that the pin on the attachment housing fits into the notch on the attachment hub. If necessary, rotate the attachment back and forth to achieve a proper position.
  
  
• 5). Turn the attachment knob clockwise and tighten to secure the attachment in place.
