MAINTENANCE AND REPAIR INSTRUCTIONS
Fig. 30
EDGER BLADE REPLACEMENT
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. 29).
2. Hold the locking rod in place by grasping it next to
the boom of the unit (Fig. 30).
3. While holding the locking rod, loosen the nut on the
blade by turning it clockwise with a 5/8 inch wrench
(Fig. 31). Remove the nut, retaining washer and blade.
Keep the nut and blade retainer for installation.
4. Install the new blade, blade retainer and nut (Fig. 32).
Insert the locking rod through the slot into the output
shaft hole. Make sure that the blade stays flat and
centered against the output shaft while tightening
the lock nut counterclockwise (Fig. 33).
5. If you have a torque wrench, tighten the nut to
325-335 in.•lbs (37-38 N•m), while holding the
locking rod in the slot.
If you do not have 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. 33).
6. Remove the locking rod.

Verify that the blade
is flat against the
output shaft after the nut is tightened. If the
blade is off-center, the unit will vibrate
excessively and may damage. Also, the
blade may dislodge and fly off, possibly
causing serious personal injury.
