DYNAMIC BLADE BALANCING KIT
PREFACE
Your ceiling fan may sometimes have wobbling problems when operating due to irregularity in the
blades or the blade brackets. Improper assembly in the mounting system may cause some additional
problems. This balancing kit can be used to fix wobbling problems.
DYNAMIC BLADE BALANCING KIT FOR CEILING FANS
1. Make sure that all blades are firmly screwed into the blade brackets.
2. Make sure that all blade brackets are firmly secured to the
motor housing
.
3. By looking up at the fan from below, check and be certain that none of the blade brackets are bent
and that none of the blades are out of position.
4. Use a yardstick to check the blade tracking. Put the yardstick up against the ceiling vertically and
against the outside leading edge of a blade. Note the distance of the edge of blade to the ceiling.
Carefully turn the blades slowly by hand to check the remaining blades.
All distances should be
the same.
Operate the fan ten minutes. After following all the steps and if the wobbling problem is not solved, a
dynamic balancing needs to be done by balancing kit. Follow the procedure listed below:
● Turn the fan off. Select one blade and place the plastic clip on it, where the plastic clip locates is
halfway between the blade bracket and the blade tip on the edge of the blade.
Caution: The plastic clip should be placed on the windward edge of the blade for fear of
clip’s flying off.
● Turn the fan on (set the speed that causes the wobble most). Observe if the wobble is better or
worse. Turn the fan off and move the clip to the next blade. Do the same for all blades and note
on which blade the clip reduces the wobble most. Place the clip on the blade which showed the
most improvement. Move the clip inward and outward on this blade and operate the fan to find
the position where the clip gives the most improvement.
Caution: Stay clear of the blades. If the clip, for any reason, is not secure, injury could result .
● Once the exact position is determined, place a weight on the top of the blade, on its centerline and
most close to the clip. Peel the paper off of the back of the weight and press firmly to ensure that
it is securely attached to the blade. Remove the clip.
Caution: Clean the surface of fan blade before placing the balancing weight so that the
balancing weight can be firmly attached on it.
