- Press the spool button (B/1) and pull the old trimmer line
out of the trimmer head.
- Cut 2 lines (dia. 2 mm x 15 m, order No. 369 224 660) to 2
meters (6.5') length each.
- Move the arrow (B/2) on the spool button so that it points
to the markings (B/3) on the cover.
Note: Before inserting the line ends into the trimmer head,
bend them to be straight over a length of 3 - 4 cm (1-2") (see
illustration).
- Insert the line ends vertically about 2.5 cm (1") through the
line guides.
Note: After about 2.5 cm (1") you should feel the line meet
resistance. If this is not the case, re-insert the line.
- Turn the spool button (B/1) in the direction of the arrow
(stamped on the housing cover) until only about 15 cm (6")
of each line protrudes from the trimmer hed.
