Operation

1. Starting and Stopping

2. Speed Control and Automatic Torque Drive Technology

• The brush cutter offers three speed options: 4,600 RPM, 5,500 RPM, and 7,000 RPM. Select the appropriate speed using the control panel buttons.
• The Automatic Torque Drive Technology (ADT) mode automatically shifts speeds to extend run time or add power as needed, optimizing performance for varying cutting conditions.

3. Reverse Rotation Function

• If the blade becomes entangled with grass or weeds, activate the reverse rotation function to quickly clear the trimmer head. Refer to the control panel for the reverse button.

4. Cutting Techniques

• For general brush cutting, use a sweeping motion, moving the blade from right to left.
• For thicker brush, approach slowly and allow the blade to cut through the material without forcing it.
• Maintain a safe distance from the blade and ensure the blade guard is always between you and the cutting area.

5. Battery Life and Management

• Battery run time will vary based on the cutting load and selected speed. Higher speeds and thicker brush will consume battery power more quickly.
• Monitor the battery charge indicators on the tool or batteries. Recharge batteries promptly when they are low to avoid interruptions.
• For optimal performance and extended battery life, always use Makita 18V LXT Lithium-Ion Batteries with Star Protection Computer Controls.

Maintenance and Care

• Cleaning: After each use, remove the battery and clean the tool, especially the blade and guard, of any grass, dirt, or debris. Use a dry cloth or soft brush. Do not use harsh chemicals or abrasive cleaners.
• Blade Inspection: Regularly inspect the metal blade for sharpness, cracks, or damage. A dull or damaged blade can reduce efficiency and increase vibration. Replace damaged blades immediately.
• Storage: Store the brush cutter in a clean, dry, and secure location, out of reach of children. Remove batteries before long-term storage.
• Extreme Protection Technology (XPT): The brush cutter features Makita XPT, a protective seal engineered to channel water and dust away from key internal components, improving operation in harsh conditions. While XPT provides enhanced durability, it does not make the tool waterproof.
