How to Adjust Ingraham Mantel Clocks

Adjusting the Time with a Key

• 1

  Open the back door to the clock and gently lift the pendulum ball out. Removing the pendulum ball before moving the clock is essential to prevent damage to the clock's movement.

• 2

  Place the clock on a flat surface.

• 3

  Insert the smaller end of the clock key into the adjustment slot. The adjustment slot is located on the face of the clock about the number "12."

• 4

  Turn the key gently to the right to speed up the clock, or to the left to slow it down. One full rotation of the key will change the timekeeping mechanism by about five minutes in a 24-hour period.

• 5

  Place the clock back in its position and place the pendulum ball back in its place. Close the back of the clock.

Adjusting the Time Without a Key

• 6

  Place the clock on a flat surface and open the back door.

• 7

  Locate the nut underneath the pendulum ball used for adjusting the timing.

• 8

  Turn the nut to raise or lower the pendulum ball. The ball should be raised to increase the speed of the clock and lowered to slow it down.

Adjusting the Striking Mechanism

• 9

  Set the hour hand of the clock to the number "1."

• 10

  Wind the minute hand slowly around the clock until it hits "12," allowing the clock to strike the hour.

• 11

  Continue doing this around the clock until you have set the correct time. Make sure to allow the clock to fully strike whatever hour you pass until you move the clock hands forward again.

• 12

  Open the back door of the clock and examine the chime and hammer. Make sure the chime is not touching any portion of the outer frame of the clock.

• 13

  Turn the minute hand of clock past "12" while examining the strike of the hammer on the chime. Make sure the hammer strikes the chime in the middle, and then returns to its home location. If this does not happen, gently bend the hammer back a little so that it clears the chime.
