Warm tips: this fan balancing kit is compatible with most ceiling fans. Specific function: the plastic balancing makes it easier to locate problem area and self-adhering 5G weights to help correct the wobble, the permanent weights are secured with a very sticky adhesive which not come free Working principle: according to the physics interpretation, when the fan rotates, the thinner the area of bearing wind is, the less will exist for the patch, and it will be more favorable for the patch to stick to the fan blade Advantages: this fan blade balance kit solves the swing problem caused by the irregular blade or blade holder, it not only helps prevent the ceiling fan from wearing, but also helps reduce noise, maintain good support of fan blades and other components to extend service life Using Steps 1. Turn the fan on and set the speed control setting to a speed at which the wobble is the greatest. 2. Turn off the fan and allow it to come to a complete stop select one blade and place the balance on it. Halfway between the blade holder and blade tip on the trailing edge of the blade. 3. Turn the fan on Note whether the wobble has increased or decreased. Turn the fan off ,move the to another blade, and retest. Repeat this procedure on all blades noting the blade on which the greatest improvement is achieved. 4. Move the back to the blade that showed the greatest improvement. Move the inward and outward on this blade and operate the fan to find the position where the gives the improvement. 5. Remove the and install a balancing weight to the top of blade along the centerline near the point where the was positioned. 6. If the fan wobble problem has not been corrected you may wish to try to improve the balancing further by using the balancing and additional weights.
