 Please keep these notes handy so you can refer to them when moving your clock, if it runs too fast or too slow or stops.

        First of all, your pendulum clock is a fine precision instrument and must be handled with care.    When CHANGING LOCATION OR POSITION of the clock, the pendulum should be removed from the movement or locked in such a way as not to apply pressure on the escapement or suspension spring,  in most cases the pendulum can be removed by lifting it up about 1/4 inch and moving it slightly to the right, left, front or rear as required to free it from the suspension rod.  It is also a good idea to stabilize the suspension rod - a rubber band straight down to a thumbtack (wood case) or piece of duct tape will suffice.  If the clock is weight driven, the weights should be labeled ( right, center, left) removed and put out of harm's way (putting them individually in old socks will keep them from getting scratched - for long moves where settling is likely, the weights should be dissembled, labeled and parts packed individually to avoid damaging the  weight cases).  At this point the clock can be moved without damage to the movement.  Once the clock is established in it's new location & leveled, the weights & pendulum can be reinstalled.
        When WINDING YOUR CLOCK it is best to do this routinely - every  Saturday morning, after church every Sunday etc.  Hold the clock firmly with one hand & wind with the other hand slowly, pausing slightly between turns.  For Weight driven clocks - do NOT force the weight up against the board at the top as you will stress the chain links & should a link fail the falling weight could severely damage the case.
        The sound the clock makes, "Tick-tock", is called the BEAT.  The time between beats must be the same.  This can be accomplished by leveling the case of the clock.  With wall hanging clocks move the bottom of the case to the right or left slightly until the beat is even.
        IF YOUR CLOCK IS NOT KEEPING GOOD TIME  The length of the pendulum can be adjusted to correct this.  Most pendulum clocks have a screw nut below the weighted part of the pendulum. When the nut is turned CLOCKWISE - tightening the nut which shortens the pendulum - the clock will speed up.  If the nut is turned COUNTER-CLOCKWISE - loosening the nut which lengthens the pendulum - the clock will slow down, just remember "LOWER IS SLOWER".  When adjusting the pendulum nut, make 1/4 turn per week adjustments until the correct time is obtained.  Also please be sure that the time source you are comparing the clock to is more stable than the clock.  If your clock does not have an adjustable pendulum, it should have  a "F" -"S" (Fast - Slow) key adjustment hole on the face.  Using the correct size key, make a 1/4 turn adjustment once per week until the time is corrected.

        IF YOU ARE GOING AWAY FOR ONE WEEK OR MORE, it is better to stop your clock rather than allowing it to run down and stop itself.  Stopping your clock can be accomplished in several different ways.  MANTEL CLOCKS - Lift one side of the case about one inch until the ticking stops, then slowly lower the case, making sure the clock remains stopped.  TALL CASE OR WALL MOUNTED CLOCKS - open the door and stop the pendulum with your hand.
        TO RESTART YOUR CLOCK - Your clock should be restarted as close to the same time as it was stopped to prevent having to move the hands more than necessary.  MANTEL CLOCKS - Lift one side of the case about 2 inches and lower it back down.  At this point it should start.  If it doesn't start ticking, repeat the process.  TALL CASE CLOCKS or WALL MOUNTED CLOCKS - Open door and gently reactivate the pendulum.
        TO RESET YOUR CLOCK - In most clocks, the HOUR HAND (short hand) can be moved forward or backward to match the correct time or striking hour.  If your clock does not strike or chime ,  the  MINUTE HAND  (long hand) can be moved FORWARD ONLY to the correct time.  If your clock strikes every quarter hour the minute hand MUST BE STOPPED AT 3, 6, 9 & 12 o'clock allowing the clock to complete the strike/chime function before moving the minute hand again.  If your clock strikes only every half hour you need only stop the minute hand & wait at 6 & 12 o'clock.
        When a clock looses time, especially after several speed adjustments, it usually means the clock is getting dirty and/or the lubricating oil is old & thickened.  This is a signal that is time to have the movement cleaned & lubricated.  To ensure the clock will remain in good working order, this should be done about every 3 or 4 years.  If done routinely, there will be little if any wear to the clock movement.  If let go, the clock movement begins to wear and additional services including the replacement of parts, will be required to bring the movement back to good condition.
        WOODEN CASE CARE  In addition to routine dusting, a coat of quality wax every 3 to 6 months will keep the case looking it's best.
