shield on your unit is not installed or if you ever need to
re-install it.

mount on the cutting attachment. Align the screw
holes in the shield with the holes in the cutting

2. Place a hex lock nut into one of the three recessed
holes on the top of the cutting attachment shield (Fig 3).
3. Install a screw into the hole from the bottom of the

1. Place the cutting attachment shield onto the shaft
housing. Be sure the guard mounting bracket slides
into the slot on the edge of the cutting shield. Rotate
the shield into place, counterclockwise. The holes in
the guard mounting bracket and cutting attachment
shield will line up (Fig. 4).
2. From inside the cutting attachment shield, push the
square bolt through the hole until the threaded end
protrudes through the guard mounting bracket (Fig. 5).
3. Put the washer on the bolt, then screw the wing nut
onto the bolt and tighten (Fig. 5).
Never operate the
trimmer without the
cutting attachment shield in place to
prevent serious personal injury.
