3. Place the cutting blade on the output shaft bushing
(Fig. 2-16).
4. Make sure that the cutting blade is centered on the
pilot step and sitting flat against the output shaft
bushing (Fig. 2-17).
If the cutting blade is off-center, the unit will
vibrate, and the blade may fly off, which can
cause serious personal injury.
5. Put the blade retainer and nut on the output shaft.
Make sure that the blade is installed correctly.
6. Tighten nut counterclockwise against the blade
while holding the locking rod;
• If using a torque wrench and an 5/8 inch socket
tighten to;
325 - 335 in•lb,
27 - 28 ft.•lb,
37 -38 N•m.
• Without a torque wrench, use a 5/8 inch closed-end
or socket wrench, turning the nut until the blade
retainer is snug against the shaft bushing. Make sure
that the blade is installed correctly, then rotate the
nut an additional 1/4 to 1/2 turn counterclockwise
(Fig. 2-18).
7. Remove the locking rod from the locking rod slot.
To avoid serious personal injury or damage to the
unit, do not start or operate this unit with the
locking rod in the locking rod slot.
Do not sharpen the cutting blade. Sharpening the
blade can cause the blade tip to break off while
in use. This can result in severe personal injury.
Replace the blade.
