My fan blades are spinning badly, what can I do?

This can happen especially if your device has been dropped or hit. To correct the problem:

• Disassemble the back (be careful, the fourth security screw is hidden);
• Remove the cover;
• Unscrew the propeller (screw reversed);
• Unscrew the 3 chrome screws holding the grille;
• Screw back in while centering, tighten;
• Reassemble the propeller and the hood.
