Anniversary clocks have a pendulum that rotates back and forth.  Hang the pendulum (it may have four balls, a disk, or figurines) on the bottom block of the suspension wire.  The pendulums on some anniversary clocks cannot be removed easily.  These clocks usually have some kind of lock that keeps the pendulum in place during transport.  Usually there is a thick, stubby, brass lever between the base of the movement and the top of the pendulum.  Hold the pendulum and turn the lever until the pendulum is released.  Some clocks have a lever in the front, under the base of the clock.  Move the lever to one side to release the pendulum. 
 
Once the pendulum is hung or unlocked, you must level the clock.  If your clock has a small ring or cup under the pendulum, level the clock until the point of the pendulum is centered in the cup.   Level the clock by rotating the leveling feet (you will see three knurled disks at the base of the clock) until the pendulum is centered, or by putting shims under the clock if it doesn’t have leveling feet.  Once the clock is level, rotate the pendulum (1/2 circle) and release.

Note:  Never move an anniversary clock without first locking or removing the pendulum.
