The standard cutting height is 2-3/4 inches. The cutting
height can be adjusted down approximately 3/4" by
turning the trimmer head disk over. To adjust the cutting
height:
1. Insert a 14mm open end wrench into the trimmer frame
(Figure 5.1).
2. Rotate the trimmer head until the wrench engages
with the trimmer shaft.
3. While holding the wrench, twist the trimmer head
weldment counterclockwise to remove. Use a slip
wrench or pipe wrench if necessary.
4. Turn trimmer head disk over and replace on trimmer
spindle.
5. Return trimmer head weldment and turn clockwise
to tighten.
