Install the new trimmer head
1. Position the flange removed in step
5, above, onto the motor shaft with
the flat surface facing away from the
base (Fig. 29).
2. Align the mounting hole in the spool
base with the motor shaft and mount
the base onto the shaft.
3. Wear gloves to hold the spool base
with one hand, and, with the other
hand, use a 1/2" (13mm) manual
socket wrench to turn the hexagon
nut clockwise to tighten it (Fig. 30).
4. Check to make sure that the washer
does not fall out of the base.
Fix the washer into the spool base as
shown below (Fig. 31).
