WARNING: The gear housing gets hot
after long periods of use. To avoid serious
personal injury, do not touch the housing
until it has cooled.
1. Line up the hole in output shaft with the locking rod
slot. Insert the locking rod through the slot into the
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.
