Installing the Blades

1.Install the first blade so that it is horizontal, along with all mounting hardware as shown in Figure 45.

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 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 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 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.
