6. Reinstall the mow ball and turn clockwise (when

Cutting string is available in two thicknesses, 155 mil
(standard) and 175 mil (heavy duty). The type of string
selected is dependent on the conditions and material
being cut.
Cutting string can be wrapped in a variety of ways. Refer
to Figures 5.2, 5.3, and 5.4 for examples. The wrapping
method and cutting string thickness chosen is ultimately
based on what is determined the best for the operator.
To wrap the cutting string in the standard configuration,
follow the steps below.
1. Feed the cutting string through the second hole on
either end of the trimmer head leaving approximately 8"
(20.3 cm) for the cutting surface. Total recommended
string length is 20" (50.8 cm).
2. Continue by weaving the cutting string through the
first hole directly beside the second hole used in
step 1. Pull the cutting string tight.
3.
Loop the cutting string back and feed through the first
hole on the opposite end of the trimmer head.
4. Feed through the remaining second hole and pull the
cutting string tight. The cutting strings in the middle
two holes should be the same length. If the length
differs, cut to an even length.
5. Optional method. Tie knot in middle of string. Insert
loose ends through holes in trimmer plate.

The standard cutting height is 2-3/4" (7 cm). The cutting
height can be adjusted down approximately 3/4" (1.9 cm)
by turning the trimmer head disk over. To adjust the cutting
height:
1. Remove front cover.
2.
Rotate the mow ball to align the flat spots of the
trimmer shaft with the opening.
3.
Use an adjustable wrench or 9/16" (14 mm) wrench
to hold the trimmer shaft. Rotate until the wrench is
braced against the trimmer body.
4. To remove, turn the mow ball counterclockwise (when
viewed from below). Use a slip wrench or oil filter
style wrench if mow ball is difficult to remove. Turning
the trimmer plate can also assist with loosening the
mowball.
5. Turn trimmer disk over and replace on trimmer
spindle.
