HOW TO SET A CUCKOO OR WALL CLOCK IN BEAT
After hanging your cuckoo clock or any wall clock on a strong nail, preferably in a stud, listen for the sound of the TICK-TOCK. The clock should have an even spaced TICK-TOCK. The concept of a correctly set up clock is addressed under, ADJUSTING MANUAL BEAT CLOCKS. Simply by moving the bottom of your clock to the left or right will change the sound of the beat. It is not important for your clock to be perfectly plumb, but more important the clock is in beat indicated by an evenly spaced TICK-TOCK. A TOCK-TICK sound is out of beat. Some clocks will not run if grossly out of beat.
If further adjustment is needed follow the instructions for ADJUSTING MANUAL BEAT CLOCKS.
