Kundo electronic swinging pendulum clocks are mantle clocks, which are short in stature and highly decorative, with brass fixtures and a clock face encased in a glass dome. They are unlike the tall case grandfather clocks, for they have shorter pendulums, which are different than the longer pendulum mechanisms on traditional clocks. The pendulum moves from side to side and has four ball-shaped bobs instead of one elongated pendulum. The inner and outer mechanisms on Kundo electronic swinging pendulum clocks work together in synchronised fashion. All parts must be in working order for the clock to function properly.

  1. 1

    Remove the glass dome from the Kundo electronic swinging pendulum clock and place it aside. Clean the movement of the clock. Shut off the movement first, then clean it with a soft cloth. Straighten the hand shaft on the clock if crooked by using a small pair of pliers or your fingers. Be careful not to break the shaft. Replace the mainspring or remove the mainspring from the barrel to clean. Make sure the suspension unit on the clock is in working order.

  2. 2

    Oil the clock pivot points around the mainspring with clock oil. A clock should be oiled once every three years. Oil the gears within the clock where the sectional gear wheels rub together. Make sure not to over oil. If the pendulum movement is too fast or too slow, adjust the pendulum bob nut. Do not overtighten the nut while adjusting.

  3. 3

    Set the clock time on the face dial of the Kundo clock. Move the minute hand every quarter hour. Listen for a chime if there is a chiming mechanism in the clock. Some electric Kundo clocks will have inner chime mechanisms that sound off on the hour. Pause the minute hand on the hour you want the clock to chime. Wind the hour hand around one time, pausing on the 12. Do not overwind.

  4. 4

    Make sure the hour and minute hand are not sticking together or pressed against the face dial. Older vintage Kundo clocks may have rusty hand dials if the glass dome is broken or missing. Take a small drop of clock oil and place it underneath the minute hand -- or remove the minute hand from the clock face -- and place a dab of oil in the centre of the clock.

  5. 5

    Replace the minute hand and tighten the nut that holds the hands in place. Pull gently on the minute hand so it isn't resting on the clock face. Make sure not to pull forward on the minute hand in a rough manner.
