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.
Tip: Break apart fiber washers from set and
then place one washer on each blade
screw prior to installing blades.
Locate 15 blade attachment screws and
washers in one of the 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 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). Align blade arm holes with
motor screw holes and attach blade arm
with lock washers and blade arm screws.
Before securing screws permanently,
repeat with remaining blade arms.
Securely tighten all screws.
NOTE: Tighten blade arm screws twice a
year.
