Installing the Blade
1. Rotate the output shaft bushing until the shaft bushing hole
aligns with the locking rod slot (Fig. 14).
2. Insert the locking rod through the locking rod slot and into the
shaft bushing hole (Fig. 14).
3. Hold the locking rod in place by grasping the other end against
the lower shaft housing (Fig. 15).
4. While holding the locking rod in place, lower the blade onto the
output shaft bushing (Fig. 16).
WARNING:
To avoid serious personal injury, make sure
that the pilot hole on the blade is sitting flat against the
output shaft bushing (Fig. 16). The unit will vibrate and the
blade may fly off if the blade is not centered.
5. Place the blade retainer onto the output shaft with the flat
surface against the blade (Fig. 16).
6. Screw the nut onto the output shaft (Fig. 16).
7. Tighten the nut counterclockwise with a 5/8 inch wrench (Fig. 17):
• If using a torque wrench, torque to: 325 - 335 in•lb, 27 - 28
ft.•lb, 37 - 38 N•m.
• If using a closed-end or socket wrench, turn the nut until the
blade retainer is snug against the blade. Make sure the blade
is installed correctly, then rotate the nut an additional 1/4 to
1/2 turn counterclockwise.
8. Remove the locking rod.
WARNING:
To avoid serious personal injury or damage
to the unit, do not start or operate the unit with the locking
rod inserted into the locking rod slot.
