Tim,
Actually, the Royal brush roll has three positions. If the bristles are worn down on the first position (1), move both ends of the roll to position 2. If worn down on 2, then move ends to position 3. After that, it's time to replace it.
To do this, according to an owner's manual, it states:
"To adjust the height of the brush, pull the brush out of the spring holders located in the ends of the nozzle. Slip the belt over the revolving brush before brush is put into new position. When brush is new, place the square end bearing adjustment so that the number 1 stamped on the bearing adjustment is visible. After the bristles have become further worn or where heavy brushing is desired, place the square end bearing adjustments in the spring holders so that the number 2 is visible. After the bristles have become further worn and it is desirable to have further adjustment, place the bearing adjustment so that the number 3 is visible. Arrows on brush roll and nozzle guard must match."
