Blade Balancing
All blades are grouped by weight. 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.

WARNING
TO REDUCE THE RISK OF PERSONAL
INJURY, DO NOT BEND THE BLADE
HOLDERS WHILE INSTALLING,
BALANCING THE BLADES, OR CLEANING
THE FAN. DO NOT INSERT FOREIGN
OBJECTS BETWEEN ROTATING FAN
BLADES.
Attaching the Fan Blades
Step 1. Insert the blade through the hole in the
blade holder and housing. Align the holes in the
blade, blade holder through and the fan motor
assembly and secure with the blade attachment
screws (1/4"x1/2") with lock washers. (Fig. 12)
Step 2. Repeat this procedure with the remaining
blades.
