Specifications

Setup and Assembly

The Makita DUR368AZ is designed for quick setup. While assembly is minimal, proper battery installation and handle adjustment are crucial for safe and effective operation.

1. Battery Installation

1. Ensure the brush cutter is turned off and the safety trigger is disengaged.
2. Locate the battery compartments at the rear of the tool.
3. Insert two 18V Li-ion LXT slide-type batteries (not included) into their respective slots until they click securely into place. Ensure they are fully seated.
4. Note: The DUR368AZ is not compatible with G-Series batteries. Using non-genuine or incompatible batteries will invalidate the Makita guarantee.

3. Safety Guard Installation

Ensure the small guard is properly installed over the cutting head. This guard is essential for user safety and increased visibility during operation.

Operating Instructions

1. Starting the Tool

1. Once batteries are installed, press the electronic power on button.
2. Engage the two-stage safety trigger switch to start the motor. The tool features a soft start for smooth initial operation.

2. Adjusting Speed

The DUR368AZ offers three speed settings (low, medium, high) to optimize performance for different cutting conditions. Use the speed selector switch to choose the appropriate speed for the application.

• Low Speed: For light trimming and extended battery life.
• Medium Speed: For general cutting tasks.
• High Speed: For dense brush and demanding applications, delivering up to 6,500 RPM.

3. Using the Reverse Rotation System

If the nylon cutting head becomes tangled with grass or weeds, activate the reverse rotation system. This feature allows the head to spin in reverse, quickly clearing debris without manual intervention.

4. Automatic Torque Drive Technology (ADT)

The ADT system automatically adjusts the motor's speed and torque during operation. This ensures optimum performance by providing more power when needed and conserving energy during lighter loads.

5. Active Feedback Sensing Technology (AFT)

For enhanced safety, the AFT system monitors the blade rotation. If the blade rotation is suddenly forced to stop (e.g., hitting a hard object), the AFT will automatically turn off the motor to prevent kickback and potential injury.

6. Nylon Cord Feeding

The nylon cord is automatically fed out by tapping the cutting head onto the ground while the tool is running. This allows for continuous cutting without manual adjustment of the line.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Makita DUR368AZ brush cutter.

1. Cleaning

• After each use, clean the tool, especially the cutting head and motor housing, to remove grass, dirt, and debris.
• Use a dry cloth or soft brush. Do not use water or solvents that could damage electrical components.

2. Blade/Nylon Head Changes

The DUR368AZ comes with an on-tool hex wrench for quick and easy blade or nylon cutting head changes. Always ensure the tool is off and batteries are removed before performing any maintenance on the cutting head.

3. Storage

Store the brush cutter in a clean, dry place, out of reach of children. Remove batteries if storing for extended periods.
