How to hang in the pendulum:
Caution!
Do always hold or carry the pendulum at the free pendulum rod, never at the adjusting-
table or the plate of the barometer-instrument.
Since the movement is already removed, the nickel plated protection tube can be pulled off
from the suspension spring block (located above the two movement holding brackets).
Remove the suspension spring and keep in
reach. Now unscrew the protection cap from
the tip of the pendulum.
To avoid damage of the delicate suspension
spring we recommend to insert it into the slot
of the pendulum rod first, hold it in place and
then hang the pendulum together with the
suspension spring into the suspension spring
block.
Push back the protection tube on the suspen-
sion spring block. By turning the nuts at the sides of the pendulum scale you can adjust the
pendulum scale in a position that the tip of the pendulum points exactly to “0”.
How to fit in the movement
Put the movement on the two brackets and screw it down with the two hexagon screws through
the lower movement pillars. So that motion can be transmitted from the movement to the pen-
dulum, the driving pin of the pallet lever must be inserted in the triangular cut-out in the safety
flap on the beat adjuster. To do so, reach into the movement from the side, carefully press the
lever with the cut-out backwards and upwards
until the driving pin slots into the triangular
cut-out.
How to start the clock
Before hanging the weight into the pulley, make sure the cables run in the foremost groove of
the barrel wheels and the pulleys.
Wind the clock with the crank one turn counter clock wise. Deflect the pendulum until a “tick”,
caused by the drop of the escapement wheel tooth on the pallet, is audible. Watch the pen-
dulum scale and note the angular minutes, indicated by the tip of the pendulum, exactly in the
moment where the “tick” occurs. Now deflect the pendulum to the other side and again note
the angular minutes when the “tick” is audible. It is ideal, when the angular minutes are equal
on both sides. If the pendulum has to be deflected more to the right side than to the left to
hear the “tick”, you can correct this by turning the adjustment screw on the pendulum rod be-
hind the movement to the right side.
Stop winding the clock, when the top end of the pulley is about 1 cm below the dial ring.
How to set the time
Caution!
Turn the hands only with the crank!
Connect the crank with the square behind the dial at 2 o´clock. Push the arbour with the crank
to the inside and turn hands clockwise. The clock should be set so that the date display always
change at night.
Caution:
Allow always the striking mechanism to chime!
In order to synchronise the second hand to that of another clock (e.g. a radio clock) stop the
pendulum when the second hand has reached the mark of the sixtieth second. Let the pendulum
go when the second hand of the clock of comparison reaches the sixtieth second.
