2. Loading Trimmer Line

This fixed line trimmer head is designed for quick and easy loading of pre-cut trimmer line. It is compatible with line diameters ranging from .080" to .105".

  1. Ensure the trimmer is turned off and disconnected from its power source (battery removed or spark plug wire disconnected).
  2. Cut two pieces of trimmer line, each approximately 10 inches long. The preferred line diameters are .080" - .105".
  3. Locate the eyelets on the side of the trimmer head.
  4. For each line, push one end through an eyelet from the outside until it emerges from the opposite side.
  5. Pull the line through until both ends are of equal length, ensuring the line is securely seated in the head. The fixed line design prevents the line from slipping out during operation.

Operation

Once the trimmer head is securely attached and the line is loaded, you can begin operation. Always follow the safety guidelines outlined in this manual and your trimmer's instruction manual.

  • Starting the Trimmer: Follow your trimmer's manufacturer instructions for starting the engine or activating the motor.
  • Cutting Technique: Use a sweeping motion to cut grass and weeds. Avoid hitting hard surfaces like concrete, rocks, or fences, as this can damage the line and the trimmer head.
  • Line Wear: The fixed line design means you will need to manually replace the line segments as they wear down. Monitor the line length and replace it when it becomes too short for effective cutting.
  • Optimal Performance: For best results, use Oregon brand trimmer line within the recommended diameter range (.080" - .105").
