output shaft hole (Fig. 27).
5. If using a torque wrench, tighten the nut to
325-335 in.•lbs (37-38 N•m), while holding the
locking rod in the slot.
Without a torque wrench, hold the locking rod in the
slot. Rotate the nut counterclockwise with a 5/8
inch closed-ended or socket wrench, until the nut
presses against the washer and the blade is snug.
Make sure the blade assembly is installed correctly,
then rotate the nut an additional 1/4-1/2 turn
(Fig. 30).
6. Remove the wrench and locking rod.
WARNING: Verify the blade is flat against
the output shaft after the nut is tightened. If
the blade is off-center, the unit will be
damaged by vibration, and the blade may fly
off, which can cause serious personal injury.
