WARNING:

wear gloves when handling the blade.
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.
Removing the Blade
1. Rotate the blade (Fig. 28) until the shaft bushing hole aligns with
the locking rod slot (Fig. 26).
2. Insert the locking rod through the locking rod slot and into the
shaft bushing hole (Fig. 26).
3. Hold the locking rod in place (Fig. 27).
4. While holding the locking rod in place, unscrew the nut by turning
it clockwise with a wrench (Fig. 27).
5. Remove the locking rod (Fig. 28).
6. Remove the blade retainer and blade (Fig. 28).
Installing the Blade
1. Rotate the output shaft bushing until the shaft bushing hole
aligns with the locking rod slot (Fig. 26).
2. Insert the locking rod through the locking rod slot and into the
shaft bushing hole (Fig. 26).
3. Hold the locking rod in place (Fig. 27).
4. While holding the locking rod in place, put the blade on the
output shaft bushing (Fig. 29).
WARNING:
To avoid serious personal injury, make sure
that the pilot hole on the blade is sitting flat against the
output shaft bushing (Fig. 29). The unit will vibrate and the
blade may fly off if the blade is not centered.
5. Place the blade retainer on the output shaft with the flat surface
against the blade (Fig. 29).
6. Screw the nut onto the output shaft (Fig. 29).
7. Tighten the nut counterclockwise with a wrench (Fig. 30):
• 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.
