To reset clock chimes, the owner must first use a level to make sure the clock is level. If the clock isn't level, the pendulum can't work. Move the minute hand clockwise to the next quarter hour, and pause to let the chimes sound, making sure it matches up.
When resetting the chimes, don't touch the hour hand because it moves on its own. When touching the pendulum or chains, make sure not to get hand oils on the metal. Repeat the process until the clock is set to the correct time. Wind the clock, and restart the pendulum with a gentle tapping motion. The chimes should reset within 2 hours.
