Installing the Blades

1. Install the first blade so that it is horizontal, along with
all mounting hardware as shown in Figure 44.
Note: Tighten the bolt with your fingers.
Important: Position the curved ends of the blades
to point toward the machine housing.
Be sure to nest the raised areas on each blade driver
with the recesses in the head of its corresponding
spindle, and the pins on the other side of each
blade driver with the holes in its corresponding
blade.

2. Steady each blade with a board and turn the blade bolt
clockwise with a torque wrench as shown in Figure 45;
torque the blade bolt to 82 N-m (60 ft-lb).
Important: A bolt torqued to 82 N-m (60 ft-lb) is
very tight. Put your weight behind the wrench and
tighten the bolt securely. This bolt is very difficult
to overtighten.

3. Rotate the installed blade 1/4 turn until it is vertical,
and install the other blade in the same manner as the
first (refer to step 1).
Note: The blades should be perpendicular, forming
an inverted "T" as shown in Figure 46.

4. Tighten the second blade; refer to step 2.
5. Rotate the blades by hand a full 360° turn to ensure
that they do not touch.
Note: If the blades touch each other, they are not
mounted correctly. Repeat steps 1 through 3 until the
blades no longer touch each other.
