Installation Guide

8. Motor Housing Assembly.
Temporarily hold motor housing up to
hanging bracket to determine which 2 screws
align with slotted holes on top rim of motor
housing. Put motor housing down and
partially loosen the 2 screws in the hanging
bracket that correspond to slotted holes in
motor housing. Remove the other 2 screws,
along with star washers, from the hanging
bracket.
Raise motor housing to hanging bracket
again, allowing slotted holes in motor
housing to align with loosened screws in
hanging bracket. Twist motor housing to lock.
Re-install the 2 screws that were previously
removed and then tighten all screws to
secure motor housing.

Time Saver: Washers for blade screws can be
set on each blade screw prior to installing
blades.
Locate 15 blade attachment screws and
washers in hardware pack. Hold blade arm up
to blade and align holes. Insert 3 blade
attachment screws (along with washers) with
fingers first and then tighten screws securely
with a Phillips screwdriver. Repeat procedure
for the remaining blades.
Remove blade arm screws and lock washers
from underside of motor. If plastic motor locks
are installed with blade arm screws, discard
plastic motor locks (save blade arm screws and
lock washers to secure blade arms). Install long
fiber washer (provided in a hardware pack)
between motor and blade arm to reduce
vibration of metal to metal surfaces. Align
blade arm holes with motor screw holes and
attach blade arm with lock washers and blade
arm screws. Before securing screws
permanently, repeat procedure with
remaining blade arms. Securely tighten all
screws.
Note: Tighten blade arm screws twice a year.
