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 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 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.
WARNING
Incorrectly installing the blades could damage the
machine or cause an injury to the operator or to
bystanders.
Cleaning under the Machine

3. Lower the machine to its lowest cutting height setting.
Refer to Adjusting the Cutting Height (page 9).
4. Attach a hose to the washout fitting, and turn the water
on high (Figure 47).
Note: Spread petroleum jelly on the washout fitting
O-ring to make the coupling slide on easier and protect
the O-ring.
