If this is not the case, there can be several possible reasons for this:
- A washer might be missing.
- The blade is poorly installed or poorly tightened.
- The fan is poorly placed in the mounting plate; the ball is not in the groove.
- Fixing the rod at the coupler is not done in the right way, and causes the fan
not to be vertical.
Adjust the height problem and move on to the next point.
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.
