Attaching the Fan Blades
Attach blades to blade arms using three screws
with fiber washers. (Fig. 17) Start a screw into
the blade arm, do not tighten. Repeat for the 2
remaining screws and washers.
Tighten each screw securely starting with the
center screw. Make sure the blade is straight.
Repeat steps for the remaining blades.
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. (Fig. 18)
