If the options previously mentioned have not worked, you can try balancing your ceiling fan. There are two methods for balancing your ceiling fan. The first method is to number each of your blades as shown in (Fig #7A). Then remove the blades that you have marked 1 and 4, as shown in (Fig #7B ),from the fan motor. Swap the location of these two blades as shown in (Fig #7C) and see if the wobble problem is corrected. If the wobble continues, replace the first two blades, and then remove the second two blades, such as blades numbered 5 and 3, and swap those two. If this still does not correct the wobble, try the next balancing method described below.

( Fig #7C )

The second method for balancing is Dynamic Balancing, which involves `counter-weighting' by using a small weight opposite to the point of wobble. Using this method, you can eliminate the wobble in almost all cases. The procedure requires much trial and error, so be patient. Determine which fan speed causes the most wobble. This will almost always be the highest speed. Turn the fan off. Start by checking to see if one of the blades or blade irons is heavier than the others. This is easy to do by tilting the fan, as shown in (Fig #8). The heaviest blade will slowly swing to the bottom. Select any one blade on the opposite side of the fan and place the balance clip half way between the blade tip and blade holder on the rear edge of the blade, as shown in (Fig #9).

CAUTION: Be careful to stay clear of the blades when running. If the clip is not secure, injury may result from the clip flying off. Turn the fan on (use the speed that causes the most wobble). Observe if the wobble is better or worse. Turn the fan off and move the clip to the next
