Atmos Clocks
Locking the Pendulum on the Atmos Clock
Atmos clock with the pendulum locked, generally the clock is locked with the lever below the dial, it is locked in right hand rotation so that when the clock is set up and the lever is released by pushing to the left the clock will start on its own. (There is also a transport lock underneath check this is unlocked before the lever under the dial). It should remain locked until you are ready to set the Atmos clock in its permanent place. Moving the Atmos clock without locking the pendulum can cause serious damage to the movement. The correct time to lock the pendulum is when it reaches an extreme swing, i.e. it stops moving. Do not lock the clock whilst the pendulum is in mid-rotation. The locking lever is quite stiff so push as gradual as you can whilst holding the clock steady.
Levelling the Atmos Clock
Atmos clocks are designed to work best when placed on a stable, level surface that does not suffer any jarring. Use the spirit level at the front of the base plate to level the Atmos clock. To level the clock the two feet at the front of the clock are raised up and down by the screws just inside the front case to assist with levelling the clock, adjust these until the bubble is completely central. If the clock will not level within the maximum adjustment of the screws, use a shim or packaging under the appropriate foot.
Setting the Time on the Atmos Clock
Set the clock to the correct time by using the minute hand only. It is best practice to move it in a clockwise direction and only when the pendulum is at, or about to reach, an extreme in its swing TO THE RIGHT, or is locked. Do not touch the hour hand or move the minute hand backwards on an Atmos clock. When the summer comes in the Spring to change the clocks for British Summer Time, just stop the clock with the lever, when the pendulum stops moving, and move the minute hand forward by an hour. In the Autumn it is easiest to just stop the clock and restart it after an hour has passed.
Starting the Atmos Clock
Once the Atmos clock has been levelled and the hands set, the locking mechanism can be undone. The pendulum should start to rotate and then keep oscillating backwards and forwards. It is best to set the hands a minute or two in advance before the door is put back in so that the lever can be released at the correct time. If the clock was stopped abruptly or accidentally jarred, do not spin the pendulum round by hand as this can damage the suspension spring and the escapement mechanism.
Timing Adjustments on the Atmos Clock
The Atmos clock is very sensitive and can react significantly to very minor adjustments. Allow the clock to settle for two weeks before making any adjustments then if the clock is running too fast or too slow, use the adjustment lever on the top of the frame which is just behind the dial at the twelve o clock position. Moving the lever TO THE RIGHT this speeds up the clock and turning the LEVER TO THE LEFT slows down the clock. The lever is marked A for advance (speed up) and R for retard (slow down). Move the lever JUST A MILLIMETER and wait at least a week for the clock to adjust then if necessary repeat. THE HANDS MUST BE SET TO TIME AFTER EACH ADJUSTMENT.
Cleaning and General Care for Your Atmos Clock
Keep the Atmos clock out of direct sunlight and avoid exposure to excessive hot or cold temperatures. The gold plating and lacquer on the case of the clock is very thin. Never use household cleaners or abrasives of any kind. Clean fingerprints and dust from the case with a very dilute, mild detergent and a soft, non abrasive cloth.
Summary
Level your clock as advised above, set your hands to time, then unlock the disc. With one hand on top of the case and release the leaver as slowly as you can till fully open.
Maintenance
To maintain the clock you should have it checked and serviced every 4-5 years. Do not attempt to oil a clock yourself. This should be done by a qualified repairer. Over-oiling a clock can affect the running and condition of the clock.
