With the Kirby in an upright position push the toe-touch lever all the way to the floor to raise the Kirby as high as it will go. Expose the nozzle on the Kirby by lifting the headlight cap. Release the belt tension by using the L-shaped handle on the belt lifter turning it all the way to the left (counter-clockwise) until the red arrows line up. Unlock the lever lock at the top of the nozzle and remove the nozzle from the unit. Unlock the rug plate by unhooking the two latches on the rear of the nozzle and remove it from the nozzle. Note the brush roll setting, which is indicated by a number or a series of notches. (See the next question for more information on the brush roll setting.) Turn the belt lifter to the right (clockwise) until the green arrows line up to release the belt from the belt lifter hook. Lift out the brushroll. Slide the old belt off and replace with a new belt. Replace the brushroll making sure each end is on the same setting. Replace the rug plate and making sure that the new belt is in the center of the brushroll, turn the belt lifter to the left (counter-clockwise) until the red arrows line up. (it will be hard to turn, as it is a new belt that you are stretching) Re-attach the nozzle to the Kirby locking it into place. Once it is locked onto the Kirby, turn the belt lifter to the right (clockwise) until the green arrows line up. This will release the belt off the hook and onto the motor shaft.
