REPLACING THE TRIMMING LINE (FIXED-LINE CUTTING
HEAD)
Only use the trimming line described in the Specifications section.
Other types of trimming line may cause the unit to overheat or fail.
WARNING:
Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
1. Remove the old line from the cutting head. Push one end of the
trimming line into the cutting head until a loop of line protrudes
from the head. Pull the loop to remove the line (Fig. 26).
2. Use a clean cloth to clean the surface of the cutting head.
3. Turn the bump knob to align the mark on the bump knob with the
mark on the spool cover (Fig. 18).
4. Insert one end of the new trimming line into a hole in the cutting
head (Fig. 24). Insert the line at the angle shown (Fig. 24). Push
the line until it protrudes from an eyelet (Fig. 25). Repeat this
process with the other end of the trimming line and the other hole.
5. Pull the ends of the line until the line is tight against the cutting
head. Make sure the ends of the line are of equal length (Fig. 26).
If one end is longer than the other, push the longer end back
through the cutting head partway and pull the shorter end out. If
necessary, repeat this process until both ends are of equal length.
6. Press the exposed loop of trimming line until it is tight against
the cutting head (Fig. 26).
