Free the hands to restart the clock.
Mantle wall clock wont stay running.
Pendulum over swing if the bob on the pendulum hasn t first been immobilized or removed from the pendulum arm before the clock is moved the pendulum can over swing go past its normal arc and throw the clock out of beat.
For mantle clocks with a pendulum a temporary cure may be to place something under one side of the clock such as a coin and listen again to see if it s any better.
Listen to the tick tock on the clock and see if it is nice even tick tock.
Turn the key slowly and just a half turn at a time.
Even though it is impossible to over wind your clock it is also not necessary to wind it until the last possible click of the ratchet.
Add two or three coins if you need to until the tick sounds even.
If the pendulum stays in the clock it may scratch the inside of the case as well as change the beat and then the clock may not work.
Moving a mechanical mantel clock from one place to another is one of the most common reasons why it stops running and can result in one of the following.
Wind it up until it stops.
It should be as level as possible and under no circumstances should it rock.
Level the clock on its four levelers if the clock stops running.
Move the pendulum back and forth with your fingers.
If it s worse place the coin under the other side instead and listen again.
The lever shouldn t be set to silent.
Do not try to force it to wind any further.
Set the lever on the dial to one of the chime selections if the clock won t chime or strike.
It doesn t matter if the case is not vertical as long as the sound is even.
It should sound steady and even like a metronome.
This may cause cracks over time at the end of the mainspring.
If it will run ok with the case at an angle we can sort that out after.
The easiest way to adjust this in the first instance is simply to tip the clock on the wall.
Gently move the hands with a finger to see if they are touching the dial the glass or each other.
