Setup and Assembly

1. Assembling the Shaft

2. Attaching the Loop Handle

Position the loop handle on the upper shaft to a comfortable operating height. Use the provided fasteners and hex wrench (stored on-board) to secure the handle firmly. Adjust as needed for optimal balance and control.

3. Installing the Battery

Ensure the tool is switched off before installing or removing the battery. Slide an 18V Li-ion LXT battery pack (sold separately) into the battery slot on the tool until it locks into place. The tool is not compatible with G-Series batteries.

4. Checking the Cutting Head

Verify that the nylon cutting head is properly installed and free from damage. This tool is designed for use with nylon cutting heads only.

Operating Instructions

1. Powering On and Off

To start the trimmer, press the power button and then pull the trigger. The tool features a soft start for smooth activation. To stop, release the trigger. The electric brake will quickly stop the cutting head for increased safety.

2. Speed Selection

The trimmer offers electronic 2-speed selection to match the application. Use the speed selection button on the control panel to switch between 'Hi' (up to 6,000 rpm) and 'Lo' (up to 4,500 rpm) settings. The constant speed control automatically applies additional power to maintain speed under load.

3. Trimming Technique

Hold the trimmer firmly with both hands, maintaining a balanced stance. Use a sweeping motion to cut grass and weeds. Avoid striking hard objects like rocks, fences, or concrete, as this can damage the cutting line or the tool.

Maintenance

1. Replacing the Cutting Line

When the cutting line becomes short or worn, it needs to be replaced. Refer to the cutting head's specific instructions for line replacement. The on-board hex wrench can be used for any necessary adjustments or disassembly of the cutting head.

2. Battery Care and Protection

The DUR192LZ features a battery protection circuit that safeguards the battery from damage due to overheating, over-discharge, and overload current. If the tool stops during operation, it may be due to one of these protection mechanisms. Allow the battery to cool down or recharge it if it's depleted. Always use genuine Makita LXT batteries and chargers.

3. Cleaning and Storage

After each use, clean the tool body and cutting head of any grass clippings or debris. Use a dry cloth; do not use water or chemical cleaners. Store the trimmer in a dry, secure location, out of reach of children. The 2-part shaft allows for compact storage.
