Blade Balancing
All blades are grouped by weight. Because aluminum
very in density, the fan may wobble even though the
blades are weighed equally.
The following procedure should correct most fan
wobbling problems. Check after each step.
1. Check that all blade and blade arm screws are
secure.
2. Most fan wobbling problems are caused when
blade levels are unequal. Check this level by
selecting a point on the ceiling above the tip of one
of the blades. Measure this distance as shown in
Figure 12. Rotate the fan until the next blade is
positioned for measurement. Repeat for each blade.
The distance deviation should be equal within 1/8".
3. Use the enclosed Blade Balancing Kit if the blade
wobble is still noticeable.
4. If the blade wobble is still noticeable,
interchanging two adjacent (side by side) blades
can redistribute the weight and possibly result in
smoother operation.
