on your string trimmer mower. Wait for the
trimmer line to stop rotating.
When the trimmer line becomes too short or worn,
change to a new trimmer line as follows:
Remove the worn trimmer line and replace with
new trimmer line packed with your string trimmer
mower. Always use OEM-743-0112 when
purchasing additional trimmer line.

going all the way through the loop. See Figure 9.
Slide the loop end of the trimmer line under the
metal tab and secure in place by crossing and
pulling tight on the ends of the line. See Figure 9.
