To use the kit to balance your blades, begin by turning your fan to find the speed where you get the most wobble.
Turn the fan off again and then attach the clip-on weight to any blade -- about halfway down. Turn the fan back on and see if it helps. If not, keep moving the weight to every other blade until you get the best results.
Once you've isolated the "problem" blade, then move the weight up and down the length of that blade (stopping and starting each time) until you locate the spot where you get rid of the wobble.
