WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit. Never perform cleaning or maintenance while the
unit is running. Disconnect the spark plug wire to prevent
the unit from starting accidentally.
WARNING:
Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
REPLACING THE TRIMMING LINE
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.
2. Use a clean cloth to clean the surface of the cutting head.
3. Insert the ends of the new trimming line into the holes in the
cutting head (Fig. 14). Push the line through the holes until both
ends protrude from the positioning tunnels (Fig. 15).
4. 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. 16).
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.
5. Press the exposed loop of trimming line until it is tight against
the cutting head (Fig. 16).
