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.

3.Make sure that you have all of the parts necessary to install the brush blade (Fig. 7). Do not remove the blade tooth cover off of the blade. Always wear gloves while handling or installing the blade.
