Blade Balancing
All blades are grouped by weight. Because
natural woods 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 13. 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.
