INSTALL BLADES
1. Position mounting end of blade assembly in an open
blade pocket on the motor assembly rim as shown.
Angle the blade approximately 45° downward and rotated
approximately 15° forward. See Fig 15. This will position
the forward tang of the blade mount between the two steel
mount rings on the motor assembly.
2. Rotate the blade backward and upward to allow the mount
end of the blade to slide into the blade pocket on the motor
assembly rim. Position the forward tang of the mount in
the forward end of the blade pocket.
3. Rotate in the same plane as the hub to seat the blade
mount into the blade pocket.
4. Insert two 6017837 5/16" dia x 1-3/4" long fasteners
from below through the hub mount ring and blade mount.
Tighten enough to hold the blade in place but do not fully
tighten at this time.
5. Repeat installation steps 1 through 4 for each of the
remaining blades.
6. Fully torque the blade mount fasteners to 12-17 ft-lbs.
