TROUBLESHOOTING - Balancing the fan blades
We do our utmost to ensure that your fan is of the highest quality. Nevertheless, it may sometimes be out of
balance. If the fan is unstable or shaking excessively, first follow the steps under 'TROUBLESHOOTING'. If
the fan persists to shake excessively, try to exchange two opposing fan blades and turn on the fan. If after
this operation the fan still persists to shake, please use the balancing set:
A
B
C
1. Turn on the fan and find the speed at which the shaking is the worst. Turn off the fan.
2. Select one of the fan blades and place the balancing clamp halfway the straight side of the blade (see
figure A). Turn the fan back to the speed at which the shaking was the worst. Check whether the shaking
has become less. Turn off the fan.
3. Repeat this procedure with each remaining blade and check which blade shows the most improvement.
4. Place the balancing clamp on the fan blade where you found the most improvement once more and
push the clamp inward or outward onto the blade (B). Turn the fan back to the speed at which the
shaking was the worst. Check whether the shaking has become less. Turn off the fan.
5. Repeat this procedure and check at which position of the balance clamp you see the most improvement.
6. Remove the balancing clamp and paste one of the two balance weights on the fan blade where you
found most improvement, exactly on the spot where the balancing clamp was located (C).
Please note that all ceiling fans can continue to shake very lightly.
