Most clock need to be wound once a week or daily. To do this, insert the key into the arbor protruding the dial and slowly turn the key in the clockwise direction or counterclockwise direction. When turned in the correct direction, the clock will produce a clicking sound indicating the correct winding direction. Continue to wind slowly until the key stops and you cannot turn it. Do not force beyond this point.
If you have a striking clock, then there will be a second winding arbor protruding the dial. Repeat the same procedure for the strike noting that this winding arbor may need to be turned in a different direction.
If your clock chimes at the quarter hour, then there will be a third winding arbor protruding the dial. Repeat the same procedure for the chime noting that this winding arbor may need to be turned in a different direction.
