Installing the High-lift Blades
Parts needed for this procedure:
2
High-lift blade
Procedure
1.
Install the first blade so that it is horizontal, along with
all mounting hardware as shown in Figure 3.
Note:
Tighten the bolt with your fingers.
Important:
Position the curved ends of the blades
to point toward the machine housing. Nest the
raised areas on each blade driver with the recesses
in the head of its corresponding spindle, and nest
the pins on the other side of each blade driver with
the holes in its corresponding blade.
2.
Steady the blade with a block of wood, and turn the
blade bolt clockwise with a torque wrench as shown
in Figure 5.
Note:
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.

an inverted “T” as shown in Figure 6.

Tighten the second blade; refer to step 2.
6.
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 this procedure 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.
