5. Operating Instructions

Follow these guidelines for effective and safe trimming.

5.1 Starting and Stopping

• To Start: Hold the trimmer firmly with both hands. Press the trigger switch on the main handle.
• To Stop: Release the trigger switch.

5.2 Trimming Techniques

For optimal results and to prevent damage to your lawn and the trimmer, use the following techniques:

• Multiple Passes: It is ideal to cut grass in multiple passes, especially for longer grass. This prevents discoloration of the lawn (brown grass) and reduces the load on the 350W motor, preventing overheating and damage.
• 1/3rd Rule: In each pass, cut no more than 1/3rd of the total grass length.
• Cutting Height: For grass less than 5 cm, a single pass is sufficient. For grass between 5 cm and 10 cm, trim in one pass. For grass between 10 cm and 15 cm, trim in one pass. Refer to the manual for specific height adjustment instructions if applicable.

5.3 Advancing the Cutting Line (Bump Feed)

The GL350L features a bump feed system to advance the cutting line.

1. While the trimmer is running, gently tap the bump head on a firm, flat surface (e.g., the ground).
2. The cutting line will automatically extend. The cut-off blade on the safety guard will trim the line to the correct length.
