7.1 Escapement

The oscillation speed of the escapement is determined by the effective length of the
balance spring. The longer it is, the slower the oscillation speed will be. To change the
running speed of the clock shorten (+) or lengthen (-) the effective length of the balance
spring by shifting the adjuster (picture 8—see page 54). One half (0,5) millimeter shift of
the adjuster result in a change of approximately 1 minute in 24 hours.

7.2 Pendulum

The length of the pendulum determines the running speed of your clock. The longer a
pendulum the slower is its swinging speed. To change the running speed, move the
pendulum bob up or down and, thus, shorten or lengthen the effective length, that is the
distance between center of gravity of the pendulum and pendulum hook. The pendulum
bob can be moved up and down by turning the adjustment nut.
Turning the adjustment nut below the pendulum bob as seen from above
counterclockwise will shorten the effective pendulum length and the clock will run faster.
Turning the
adjustment nut clockwise will lengthen the effective pendulum length and the clock will
run slower (picture 9 - 55).
One third (0,33) turn of the adjustment nut will result in a change of approximately 1
minute in 24 hours. Please make sure that the pendulum bob remains fully seated against
the
adjustment nut and pull it down as needed.
Remember to reset the time after adjusting the pendulum bob.

8. The automatic night shut-off (option)

Most clock models feature an option which will allow you to activate an automatic
silencing of the chime between the hours of 10:00 P.M. and 7:15 A.M. (for quarter hour
strike
movements) or 10:00 P.M. and 7:00 A.M. (for half hour strike movements). Use the lever
as identified in section 6 to select this option. The position of the chime selection lever is
marked with «NIGHT OFF».
Some models include a so called "permanent night shut-off" which can not be deactivated.
If your clock does not strike or chime during the daytime, its movement is in the night
cycle. You need to move the clock hands back 12 hours to go into the day cycle. Before
doing so the night shut-off has to be turned off or the chime selector lever set on
«SILENT». Moving the hands while the night shut-off is in operation could damage the
chime mechanism.
If after setting the time, the clock does not chime properly, this is not a defect. The
movement has a self correcting feature which synchronizes the chimes after 1 to 2 hours.

9. Care and Maintenance

Your clock requires very little care and maintenance.
Listed below are some steps you can take to maintain the function and appearance of your
clock for many years:
{ Wind your clock regularly (every seven days).
{ Keep the door(s) closed.
{ Check periodically to ensure that your clock is standing level and securely.
