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 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.
