To regulate your clock, hold the pendulum disc and turn the rating nut located under the disk to the left to make the clock run slower and to the right to make the clock run faster. One turn of the nut will regulate time keeping approximately two minutes a day. Be sure the pendulum disc moves downward when the rating nut is turned to the left; it may be necessary to gently push the disc downward on the pendulum rod.

It is better to adjust the rating nut in small increments at a time and slowly approach correct time keeping as opposed to turning the nut too far in either direction on the initial adjustment.
