the line spool clockwise. Remove the line spool and
retainer washer from the shaft (Fig. 6).

4. Install the blade, washer, and lock nut. Insert the
locking rod into the locking rod slot (Fig. 7). Make
sure that the blade stays flat against the washer while
tightening the lock nut counterclockwise until it is
finger-tight.
5. If you have a torque wrench, tighten the lock nut to
225-250 in•lb (25.3-28.1 N•m), while holding the
locking rod in the locking rod slot (Fig. 7).
If you do not have a torque wrench, thread the
lock nut onto the brush blade by hand as tightly as
possible (Fig. 8). Using an open-ended wrench, rotate
the nut 1/2 - 3/4 of a full turn (minimum) (Fig. 9).
The torque of the nut should be within the required
specifications of 225-250 in•lb (25.3-28.1 N•m).
The blade tooth cover can now be removed.
