TROUBLESHOOTING

ALL CLOCKS MUST BE SERVICED EVERY TWO TO THREE YEARS!!! Not doing so could cause serious damage to your clock!

400 DAY CLOCKS

- Set the clock upon a level surface completely from vibration

- Pull up the class case and take off the paper packings

- There is a set screw in the under surface of the clase base or a pendulum locking lever towards the bottom of the mechanism that needs to be loosened to free the pendulum

- If you are going to move the clock, do the oposite and lock the pendulum in place

- Make certain that the bottom point of the pendulum hangs directly over the center of the cup. Accurate leveling is accomplished by adjusting the leveling screws through the legs in the under surface of the clock base

-When pendulum is stationary, rotate it slightly either to the right or the left, approximately on half turn, then release

- On the top of the pendulum is a disc on which two arrows with S and F are engraved. Should the clock run slowly, turn the disc slightly in the direction of F. If the clock is running fast, turn the disc slightly in the direction of S. One division of the disc means 2 minutes per day

PENDULUM CLOCKS

- Mantle clocks must be placed on frim, even surfaces

- A number of factors can affect the timekeeping of a clock (temperature, balance, etc.). No matter how well a clock may have been overhauled, final adjustment is almost always necessary.

- The longer the pendulum, the slower the clock will run. Most pendulums have a rating nut under or in the bob, and small adjustments should be made as necessary.

- Do not alter the pendulum more than once in 24 hours and remember that spring driven clocks may run slower as the spring unwinds. Keep a note of the amount of adjustments made and the resulting effects.

- Some clocks, particularly heavy French ones, have pendulum suspension systems that allow regulation without moving the case. A watch of double-ended key will fit the arbor protruding through the dial near the numeral 12. Generally, rotation of the arbor in a clockwise direction shortens the effective length of the pendulum, thus making the clock faster.

- NEVER MOVE THE CLOCK WITH THE PENDULUM ATTACHED, as this will put it out of beat, damage the delicate spring on which the pendulum is suspended and may cause expensive damage to the escapement.

- A clock is 'in beat' when the intervals between the ticks are exactly equal. An 'out of beat' clock can be heard ticking unevenly, with alternately long and short intervals between ticks. IF A CLOCK IS OUT OF BEAT, IT WILL NOT RUN CORRECTLY!!!

- Wallclocks may be given their final adjustment by moving the bottom of the case very slightly to one side or the other.

- Mantle clocks may be given their final adjustments by placing pennies or shims under one side or the other of the legs.
