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.
9. Blade Assembly.
WARNING: To reduce the risk of serious bodily
injury,
DO NOT use power tools to assemble the
blades. If screws are overtightened, blades may
crack and break.
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 (if not already pre-attached to blade arm)
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.
