Operating Instructions

The DEWALT String Trimmer features a variable speed trigger with Hi/Lo speed control, allowing you to adjust power for different tasks and extend runtime.

• Starting the Trimmer: Press the safety lock-off button (if present) and then squeeze the variable speed trigger to activate the trimmer.
• Speed Control: Use the Hi/Lo speed control switch to select the desired power level. The 'Hi' setting provides maximum power for tough overgrowth, while 'Lo' conserves battery life for lighter trimming.
• Trimming Technique: Hold the trimmer firmly with both hands. Use a sweeping motion to cut grass and weeds. Maintain a safe distance from obstacles and other individuals.
• Edging Functionality: For edging along concrete, fences, or around trees, the trimmer head can be rotated or flipped to achieve a precise edge. This allows for versatile use beyond just trimming.
• Line Advancement: The bump feed head allows for easy line advancement. Lightly tap the trimmer head on the ground while the motor is running to feed out more line.

Maintenance

The DEWALT FLEXVOLT String Trimmer is designed for low maintenance, eliminating many common tasks associated with gas-powered equipment like carburetor adjustments, spark plug changes, and air filter cleaning.

• Trimmer Line Replacement: When the trimmer line runs short, replace it with 0.080-inch or 0.095-inch diameter line. Follow the instructions provided with your replacement line spool for proper installation into the bump feed head.
• Cleaning: After each use, clean the trimmer head and shaft to remove grass clippings, dirt, and debris. Use a damp cloth; do not use harsh chemicals or abrasive cleaners. Ensure the battery contacts are clean and dry.
• Storage: Store the trimmer in a dry, secure location away from children and direct sunlight. Remove the battery before storing for extended periods.

Troubleshooting

If you encounter issues with your DEWALT String Trimmer, consider the following common solutions:

• Trimmer Not Starting: Ensure the battery is fully charged and properly inserted. Check that the safety lock-off button is fully depressed before squeezing the trigger.
• Insufficient Cutting Power: Verify that the trimmer line is not too short or worn. Advance new line if necessary. Ensure the trimmer is set to the 'Hi' speed setting for demanding tasks.
• Line Not Advancing: Check for tangled or jammed line in the bump head. Ensure the line is properly wound on the spool.
• Overheating: If the motor feels excessively hot, stop operation immediately and allow the tool to cool down. Ensure air vents are clear of debris.
