~Always remove weights and/or pendulum when moving clock to a new location.
~Always Stop to let the clock chime when resetting time.
~Never turn the minute hand backwards.
~Level Clock front-to-back and side-to-side before hanging pendulum and/or weights.
~At daylight saving time (Spring), turn hands forward to correct time. When standard time returns in Fall, stop clock for one hour, then restart at the proper time.
~Clock too slow? Turn pendulum adjuster to the right (clockwise) or up for a cuckoo clock.
~Clock too fast? Turn pendulum adjuster to the left (counter-clockwise)or down for a cuckoo clock.
Pendulum Clocks will run faster in winter and slower in summer due to the effects of heat and humidity. Most homes are generally dryer during the heating season. Dry items shrink, therefor, pendulums get shorter. When the humidity returns in the summer, the pendulum will "grow" longer again. This is true for both metal and wooden pendulums.
*Unlike electric and quartz clocks, Pendulum powered clocks are not precision time keepers. It is normal for old clocks to gain or lose some time because of weather conditions and how tightly the spring(s) is wound.In Pennsylvania and nearby states pendulum clocks may gain or lose up to one minute a day during a seasonal change, but once adjusted it should maintain normal time keeping until the next drastic weather change.In other parts of the country it may be normal for a pendulum clock to gain or lose more than minute. If your clock continues to lose or gain time, it may need further adjustment or professional service.
