Rotate the blades by hand while tightening the
•
blade bolt. This is especially important because it
assures the belt is not squeezed between the pulley
halves, which are incorporated into the blades.
Alternate between tightening the blade bolt and
rotating the blades until the blades are fully
tightened. Tighteningtorque for the bolt holding the
blade is: 130 in.lb (15 Nm).

the nut is tightened. This is to ensure that the belt is not
clamped between the integrated drive belt halves on the
blades when the blades/drive belt are pulled together
with the nut. Ideally this is done alternately, i.e. tighten a
little, rotate a little and repeat until the blades are
secured.
