Level the clock on its four levelers if the clock stops running.
Mantle wall clock wont stay running.
This may cause cracks over time at the end of the mainspring.
Free the hands to restart the clock.
Mantel clock does not strike the correct hour if after several hours of operation your clock does not strike the correct hour grasp the hour hand only and move it forward or backward to line up with the correct hour on the dial indicated by the number of times the hour strikes.
If it will run ok with the case at an angle we can sort that out after.
Turn the key slowly and just a half turn at a time.
Do not try to force it to wind any further.
Gently move the hands with a finger to see if they are touching the dial the glass or each other.
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.
The easiest way to adjust this in the first instance is simply to tip the clock on the wall.
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.
To correct a spring driven clocks mantle or wall clock that is bonging the hour when the minute hand gets to 6 o clock instead of 12 o clock just count the bongs take off the minute hand and reinstall it on the clock pointing to 12 o clock then turn the hour hand to the hour you heard the clock bong and its done.
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.
Add two or three coins if you need to until the tick sounds even.
Wind it up until it stops.
If it s worse place the coin under the other side instead and listen again.
The lever shouldn t be set to silent.
It should sound steady and even like a metronome.
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.
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.
Move the pendulum back and forth with your fingers.
It should be as level as possible and under no circumstances should it rock.
If you don t hear a ticking sound the clock s hands are probably stuck.
