Adjusting and Regulating
After the clock is mounted on the wall, it will likely need some adjustment in order to get it running
properly. Follow the steps below for initial adjustment of the clock. If you still experience
difficulty in getting the clock to operate, see the Troubleshooting section of these instructions.
1) Verify proper play in arbors.
Each arbor should have a small amount of play (about 1/16") so that the arbors can be
jiggled back and forth between the frame pieces. If necessary, move gears or set washers
until proper play is established.
2) Check gear mating.
Verify that each gear is mating properly with its neighbor and that no gear is binding.
3) Bring clock into beat.
A slight push of the pendulum shaft to one side should start the clock in motion. The clock
will most likely stop after a few seconds or minutes as the escape lever hangs up on an
escape wheel tooth. If the escape wheel stops the motion after only a few swings, adjust the
position of the clock on the wall as follows: if the escape lever hangs up its right side, rotate
the clock slightly clockwise. This will raise the right side of the escape lever. If the lever
hangs up on the left side, the clock must be rotated slightly counterclockwise in order to
raise the left tip of the lever. Adjust until the pendulum will make several oscillations
before stopping. Small adjustments of the clock’s vertical position should bring the clock
into beat. The vertical orientation of any pendulum clock is critical.
Once the clock’s correct position is established tighten the acorn nut to firmly secure the
clock to the wall. If needed, an additional anchor can be added. Mark on the wall the
location of the slot in the upper portion of the rear frame. Remove the weight and
pendulum, and carefully rotate the clock out of the way so that a wall anchor can be driven
in at this point. Drive the wall anchor into the wall, reposition the clock, place a washer on
the anchor screw and drive it through the slot into the anchor. Tighten both this anchor and
the acorn nut. Replace the pendulum then the weight and doublecheck the clock beat as
described in the previous step. Once the proper position is established, further tighten both
wall anchors so the clock cannot move on the wall.
4) Setting the time
The hour and minute hands need to be set independently. Both hands should be friction fit
on their shafts so that they can be rotated. You should grasp the great wheel when setting
the hands to prevent the entire motion train from moving. After positioning the hands,
verify that neither hand was inadvertently angled inward or outward so that it rubs on or
interferes with the other hand or with the gear on the front of the clock.
