Raise the pendulum to increase the speed, and lower the pendulum to decrease the speed.
Before adjusting the pendulum, place
either a red or a black dot where the pendulum nut enters the front of the pendulum.
Use the dot to determine the length of one full turn. Turning the nut
to the right one full turn speeds up the pendulum by one minute and turning the pendulum one full turn to the left slows the
pendulum by one minute. After adjusting the pendulum, allow the clock to settle
for one full week, and then readjust as necessary.
Level the clock and start the pendulum. You should hear a distinct ‘tic-tock’ noise. If you do not hear this noise, push the pendulum lightly to the left or right until the clock says ‘tic-tock.’
