8. Blade Assembly.
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 packs. 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/lock washers from
underside of motor and if needed, locate the
others in one of the hardware packs. If plastic
motor locks are installed with blade arm screws,
discard plastic motor locks (
save blade arm
screws/lock washers to secure blade arms
).
Slide a
blade arm into one of the square holes in the
side of motor housing. Align blade arm holes
with motor screw holes and attach blade arm
with blade arm screws/lock washers. Before
securing screws permanently, repeat procedure
with remaining blade arms. Secure all screws.
Note
: Tighten blade arm screws twice a year.
Remove 1 screw from motor plate on
underside of motor housing and partially
loosen the other 2 screws. Align slotted holes
in switch housing plate with loosened screws
in motor plate, allowing male plug from
motor housing to come through hole in
middle of switch housing plate. Twist switch
housing plate to lock. Re-insert screw
previously removed and securely tighten all 3
screws with a Phillips screwdriver.
