7 - MAINTENANCE INSTRUCTIONS
7-1. REPLACING CUTTING LINE
1. Turn knob (A) COUNTERCLOCKWISE and remove
(Figure 7-1A).
2. Remove spool (B) and spring (C) from spindle (D).
3. Remove any remaining cutting line (H).
4. Fold over evenly a 14' (4.3m) length of .095 or .080"
(.24 or .20cm) cutting line. Place the looped center in
one of the slots (G) of the spool divider (Figure 7-1B).
5. Wind cutting line clockwise as shown in illustration
(Figure 7-1C), keeping tension, with each half sepa-
rated by the spool divider. Wind to within 6" (15cm) of
the ends.
6. Lock each end of line into a slot (F) on opposite sides
of the spool (Figure 7-1D).
7. Install the spring (C) over the spindle (D). Insert each
end of the line through an eyelet (G) in the housing (E)
(Figure 7-1E).
8. Lower the spool into the housing (E) while feeding the
line through the eyelets (G). Ensure the spring seats
itself into the spool (Figure 7-1E).
9. Once the spool is in place, apply pressure on the
spool compressing the spring. Pull each end of the
line (H) sharply to unlock the line from the slots
(Figure 7-1F).
10. Continue to apply pressure to the spool until the knob
can be threaded CLOCKWISE onto the spindle.
Tighten the knob securely by hand only (Figure 7-1G).
11. Trim the excess line to approximately 5" (13cm). This
will minimize load on engine during starting and
warm-up (Figure 7-1H).
