After following all the steps if the wobbling problem is not solved, a
dynamic balancing needs to be done with balancing kit. Follow the
procedure listed:
Turn the fan off. Select one blade and place the plastic clip on it, where
•
the plastic clip locates is halfway between the blade holder and the
blade tip on the edge of the blade.
CAUTION: The plastic clip should be placed on the windward edge of the
•
blade to avoid clips 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 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 centre line and closest to the clip. Peel the paper off 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.
