2 Distance between the blades
Choose a mark on the tip of the blades and use the same mark on each blade.
Using a meter, measure the distance between each blade, it must be the same.
If this is not the case, unscrew slightly the screws that support the blades, place
the blades on the correct axis and tighten them.

3 Blades Length
One of the blades may be 3 or 4 millimeters longer, because when it is installed, by
tightening the screws, the blade can slide upwards.
Check the distance from the center of your fan towards the blade tip.
If you notice that one of the blades is longer, loosen the screws ofthis blade, and
tighten them firmly, making sure the blade does not slip.
