• Always wear safety glasses, hearing protection, and sturdy footwear when operating the trimmer.
• Ensure the work area is clear of debris, rocks, and other objects that could be thrown by the cutting line.
• Keep bystanders, children, and pets at a safe distance (at least 50 feet/15 meters) from the operating area.
• Do not operate the trimmer in wet conditions or rain.
• Inspect the trimmer for any damage or loose parts before each use. Do not operate if damaged.
• Use only genuine Greenworks replacement parts and accessories.

Trimming Techniques

• Sweeping Motion: Use a side-to-side sweeping motion, keeping the trimmer head parallel to the ground.
• Edging: Tilt the trimmer head to a vertical position to create clean edges along sidewalks and driveways.
• Cutting Height: Adjust the angle of the trimmer to achieve desired cutting height.
• Dense Growth: For very thick grass or weeds, make smaller passes to avoid bogging down the motor. The 60V brushless motor is designed to power through tough vegetation.

Line Advancement (Load N Go™ Head)

The Load N Go™ trimmer head simplifies line replacement. To advance the line, simply tap the trimmer head on the ground while the trimmer is running. For reloading new line:

1. Step 1: Line up the green lines on the trimmer head.
2. Step 2: Insert a new .095" dual line through the head, pushing it until an equal length protrudes from both sides.
3. Step 3: Twist the head clockwise to wind the line into the spool. This process takes approximately 10 seconds.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your trimmer. Always disconnect the battery before performing any maintenance.

Cleaning

• After each use, clean the trimmer head and guard to remove grass clippings and debris.

• Ensure ventilation openings are clear of obstructions to prevent overheating.

Line Replacement

When the cutting line becomes too short or breaks, replace it using the Load N Go™ system as described in the Operating Instructions section. Use only .095" diameter trimmer line.

Storage

• Remove the battery pack from the trimmer before storing for extended periods.
