5. CLEANING AND MAINTENANCE
WARNING: before cleaning or repairing the fan, disconnect it from the mains.
1. Clean the fan regularly.
2. When cleaning, only use a soft brush or lint-free cloth to avoid scratching the finish.
3. Abrasive cleaning agents are not necessary and should be avoided in order not to damage
the finish.
RECOMMENDATION: periodically check that the blades are securely fastened to the motor with
the screws.
WARNING: do not use solvents to clean the fan. Doing so may result in a risk of electric shock.
6. TROUBLESHOOTING
Troubleshooting (wobble)
- Note that not all ceiling fans are the same (not even those that are the same model), some
move more than others. The fact that the fan moves a couple of centimetres does not
indicate that it will fall over.
- Even if all blades are ballasted and grouped by weight, it is impossible to completely avoid
wobble. This is not a problem. Ceiling fans tend to move during operation.
To reduce wobble, try the following:
1. Check that all of the blade mounting screws are tightened and secure.
2. Fan wobble may be caused by the unevenness of the fan blades. To check the blade level,
measure the distance from each blade tip to the ceiling. If measurements are irregular:
- Be sure the blade mount screws are not too tight or too loose, which may cause
wobbling due to an unlevelled blade tip.
- A deformed blade can cause wobbling. Check by removing the blade and placing on a
flat surface.
- Blade tracking may be checked simply by use of a household ruler. Place the ruler
vertically against the ceiling and even with the outside leading edge of a blade. Note
the distance of the edge of a blade compared to the others. Turn the blade slowly by
hand to check the remaining blades.
NOTE: if a blade is not in alignment, the blade is either out of shape, warped or the blade screws
are not evenly tightened or either loose.
