Attaching the Fan Blades
Step 1
Attach the blades to the blade arms using
three screws with fiber washers as shown in
Figure 12. Start a screw into the arm, do not
tighten. Repeat for the 2 remaining screws and
washers.
Step 2
Tighten each screw securely starting with
the center screw. Make sure the blade is straight.
Step 3:
Fasten the blade assemblies to the motor
housing by lining up the slots of the blade arms
with the tabs on the motor housing, then tighten
the two screws and washers already installed in
the blade arms. (Figure 13)
