Ridgeway EIGHT DAY CLOCKS Manuel Du Propriétaire page 8

The distance the pendulum disc hangs from the clock movement determines how fast or slow your clock runs. This distance
can be changed by turning the nut which is located below the pendulum disc. Turn the nut to the right and the pendulum
gets shorter and the clock runs faster. Turn the nut to the left and the pendulum gets longer and the clock runs slower.
Some models such as lighted pendulums or glass pendulums will have the adjusting nut located above the disc and comes
through a slot in the harp (lyre). (Marked on Fig 19 A.) The adjustment is the same on both types of pendulums.
In order to make this adjustment follow these simple instructions:
1. Stop the pendulum.
2. Hold the pendulum steady by placing one hand on the pendulum disc as shown in Figure 19A.
3. Make the following adjustments with your other hand. It is not necessary to remove the pendulum from the clock to make
this adjustment. You do want to hold the pendulum firmly however so you won't damage the suspension spring which is
located at the top of the pendulum.
DAY ONE
1. Select a time of day when you can check your clock the same time every day for seven days.
2. Record the time you have selected. (example 7:00 PM)
3. Check the correct time. (Most phone companies have this service, look under TIME. Make note of the number you
will need it each day.)
4. Re-set the time using the minute hand (longest).
DAY TWO THROUGH SEVEN (If necessary. Stop when correct time shows on new day.)
1. Check the correct time.
2. Compare the time shown on your clock with the correct time. Is your clock running fast or slow?
How many minutes?
3. Turn the adjustment nut on the pendulum one complete revolution for each minute (approximate)
fast or slow per day. (24 hours). Accurate time adjustment varies for every pendulum.
4. Check the correct time again.
5. Re-set the minute hand to the exact correct time.
