Setup
- Handle Assembly: Attach the auxiliary handle to the shaft. Ensure it is securely tightened for comfortable and safe operation.
- Guard Installation: Securely attach the safety guard to the trimmer head using the provided hardware. This guard protects against flying debris.
- Adjusting Shaft Length: The trimmer features an adjustable shaft. Loosen the locking collar, extend or retract the shaft to a comfortable operating length, and then securely tighten the collar.
- Power Connection: Connect the trimmer's power cord to a suitable outdoor-rated extension cord. Ensure the extension cord is rated for outdoor use and is of appropriate gauge for the length required. Secure the trimmer cord to the extension cord using the cord retention hook to prevent accidental disconnection.

Operating Instructions
- Starting the Trimmer: Plug the extension cord into a grounded outdoor outlet. Hold the trimmer firmly with both hands. Press the safety lock-off button and then squeeze the trigger switch to start the motor. Release the lock-off button once the motor starts.
- Trimming Technique: Hold the trimmer at an angle, allowing the tip of the cutting line to do the work. Use a sweeping motion from side to side. Avoid hitting hard objects like fences, walls, or trees, as this can damage the line and the trimmer.
- Edging Technique: To convert to an edger, press the pivoting head adjustment button and rotate the head 90 degrees. The edging wheel will guide the trimmer along hard surfaces like sidewalks and driveways. Walk slowly and maintain a steady pace for a clean edge.
- Line Advancement: This trimmer features an automatic line feed system. The line will advance automatically as it wears down. If the line does not advance, briefly tap the trimmer head on a hard surface while the motor is running (ensure safety precautions are followed).
- Stopping the Trimmer: Release the trigger switch to turn off the motor. Disconnect the power cord from the outlet after use.

- Line Replacement: When the cutting line runs out, replace it with Greenworks replacement spool, model 29082. Refer to the specific instructions provided with the replacement spool for proper installation.
- Storage: Store the trimmer in a dry, secure location out of reach of children. Avoid storing in direct sunlight or extreme temperatures.
