Installing the Blades
1. Install the rst blade so that it is horizontal, along
with all mounting hardware as shown in Figure 45.
Note: Tighten the bolt with your ngers.
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 46; torque the blade bolt to 60 ft-lb (82 N-m).
Important: A bolt torqued to 60 ft-lb (82 N-m)
is very tight. Put your weight behind the wrench
and tighten the bolt securely. This bolt is very
difcult 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 rst (refer to step 1).
Note: The blades should be perpendicular, forming
an inverted “T” as shown in
Figure 47.

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.
