The following procedure should correct most
fan wobble issues. Check after each step.
1.
Check
that all blades and blade holder
screws are secure.
2. Most fan wobble 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 17. Rotate the fan
until the n ex t b lade is posi ti on ed for
measurement. Repeat for each blade. The
distance should be equal within 1/8".
If all blade levels are not equal, you can
adjust the blade level with the following
procedure.
3. Use the enclosed Blade Balancing Kit if the
blade wobble is still noticeable. (Please refer
to the introduction provide in the blade
balancing kit, which is individually packed.)
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.

Blades
1. A ttach the blades to the blade holder
using three screws and paper washer as
shown in Figure 15. Start a screw into the
blade holder, do not tighten. Repeat for
the 2 remaining screws and washers.
2. Tighten each screw securely starting
with the center screw. Make sure the blade
is straight.
3.
4. F asten the blade assemblies to motor
housing by tightening two previous
removed screws from the motor housing.
(Figure 16)
Remove the plastic blocks before
installing the blade holder to the bottom
motor housing, discard the plastic blocks
but keep the screws. (Figure 16).
