Congratulations on buying a clock from us. The mechanical movement in your clock is of German origin, hand tested both there and after installation in our workshop. These instructions therefore do not replace the personal attention your clock receives from us during manufacture, delivery, setting up or thereafter.
Setting up of a clock fitted with a Hermle movement only
- The cabinet itself fitted with the movement.
- Three weights - two in the case of weight driven Wall clocks.
- The pendulum.
- A winder and/or key in the case of cable movements and clocks with spring cases.
- In case of a clock that chimes on tubular bells, these will be packed separately.
- Remove the material that keeps the gong rods apart during transport.
- Chain movements: Undo the tape that keeps the chains together. Hold the chains together as they may have come off their sprockets during transport. To rectify this, simply feed them into the leading edge as you would a bicycle chain.
- Cable movements: The loose end of the cable is secured under the movement- ensure that it is still in place. It can slip out during transport.
- Tubular movement: Remove the top back of the clock to expose the movement. Clear the 9 hammers suspended on spring arms of all packing material.
The pendulum has to be attached to the pendulum hanger/guide which is fitted to the back of the movement just in front of the gong rods. Hold the pendulum guide with one hand, whilst with the other hand, you place the pendulum through the slot of the pendulum guide. Lower the pendulum now until it hangs securely from the pendulum guide/hanger.
- Grandfather Clocks: Two of the three weights are the same in mass but the third one is heavier. The two lighter weights have hooks at the top and should be attached to the left and middle chains/cables respectively. The heaviest weight has an eyelet and should be attached to the right hand chain/cable.
The functions of these three weights are as follows:
- The right hand weight regulates the chimes on the quarter hours.
- The left hand weight regulates the hourly chimes.
- The middle weight keeps the clock running.
- Wall clocks: The two weights are even in mass. Hang both.
Shift the clock’s chime setting to Silent (see below if you aren’t sure how to Silence movement) and move the minute hand clockwise to the correct time. The chimes can now be activated. Although the chimes have now lost their synchronicity with the time, the mechanism will correct itself within two hours.
The moondial indicates the phases of the moon by rotating clockwise as long as the clock is running, with the moon around the earth on the 29.5 lunar calendar. The stars are decorative and don’t correlate to constellations in the sky.
With your fingertips apply slight pressure to the front of the moon dial and rotate it clock wise until it is directly under #15-the 15th lunar day on the calendar. Now refer to a calendar and determine how many days elapsed since the last full moon. Move the moon dial on correspondingly, i.e. as many days as has elapsed since the last full moon.
There is at least one pulley lever hanging from behind the dial of your clock
- Clocks with one pulley lever: If pushed upwards the night shut off is activated from 22:00 to 07:00 until the bar is pulled down again.
- Clocks with two pulley levers: The bar on the right: If this bar is pushed upwards the clock is set on Silent and will not chime at all. In the downward position you will enjoy full chimes, 24 hours a day.
- The bar on the left is a Night shut off function. If pushed upwards the night shut off is activated from 22:00 to 07:00 until the bar is pulled down again.
- Clocks with three pulley levers: Added to the above two functions, the bar on the far left silences the hourly gong when pushed upwards.
- Clocks with adjusting facilities on the dial: The functions will be lettered on the dial. If there is a lever hanging from behind the dial, it will be the night shut off facility. See Above
- If you own a clock with more than one chime then the bar on the far right of your clock also serves as the selector between the different chimes:
- Down= Westminster
- One up = St. Michael
- Two up = Whittington
- Three up = No quarter chimes
- Four up = Silent
Adjusting the clock for accuracy:
This is usually necessary as the specific pendulum and mechanism brought together in your cabinet have not been set to run at the right speed yet.
At the bottom of the pendulum is a setting nut that will retard or advance the speed of the clock. If the clock runs fast (gains time) the setting nut must be turned from right to left i.e. downwards. This will lengthen the pendulum and thus make it go slower. The reverse procedure applies if the clock runs slow. The nut must be turned from left to right i.e. upwards. This will shorten the pendulum and make it go faster. Don’t be shy to turn the nut 20-30 times at first. This will ensure that you can see progress sooner than later.
All mechanical movements are known as 8-day movements and require winding once a week. All three weights in the case of grandfather clocks, both weights in the case of weight driven wall clocks and all spring cases need winding.
- Chain driven movements: To wind the clock the respective chains must slowly and evenly be pulled downwards to raise the weights. Never over wind - the full length of the weight must be visible through the glass of the door.
- Cable driven mechanisms are wound by turning the winder clockwise until it will go no further. Spring or coil driven mechanisms are wound clockwise until the stiffness comes to full resistance (after approx.10-12 “wrist winds”).
