5.3 Line Feeding (Bump & Feed)

The trimmer is equipped with a bump and feed head. To advance the trimmer line, gently tap the trimmer head on the ground while the motor is running. This will release a small amount of line. The cutting blade on the guard will automatically trim the line to the correct length.

5.4 Edging

For precise edging along sidewalks or driveways, tilt the trimmer head to a vertical position. Walk slowly and steadily, guiding the line along the edge to create a clean cut.

6. Maintenance

6.1 Cleaning the Trimmer Head

After each use, ensure the trimmer head and guard are free from grass clippings, dirt, and debris. Use a brush or cloth to clean the surfaces. Do not use harsh chemicals or abrasive materials.

6.2 Replacing Trimmer Line

When the trimmer line runs out, it needs to be replaced. The trimmer uses 0.080" twisted quiet line. Refer to the detailed instructions in the full product manual for specific steps on how to open the bump and feed head and wind new line. Ensure the line is wound correctly to prevent tangles and ensure proper feeding.

• Trimmer line does not feed: Check for tangled line inside the bump head. Ensure the line is not too short or improperly wound.
