- Wall Hanging Hook
- Operator's Manual

Setup and Assembly
- Prepare the Power Head: Ensure your Greenworks attachment-capable string trimmer power head is turned off and the battery (if applicable) is removed for safety. Refer to your string trimmer's instruction manual for specific power head preparation steps.
- Attach the Blower Head: Align the shaft of the HBA45 blower attachment with the coupling on your string trimmer's power head. Push the attachment into the coupling until it clicks securely into place. Tighten any locking knobs or levers on the power head as instructed in your trimmer's manual to ensure a firm connection.
- Select and Attach Nozzle: Choose either the concentrator nozzle for focused airflow or the flared nozzle for broader coverage. Slide the desired nozzle onto the end of the main blower tube until it is firmly seated. Ensure it is securely attached to prevent it from detaching during operation.


Operating Instructions
- Safety First: Always wear appropriate personal protective equipment (PPE), including eye protection, and ensure bystanders are at a safe distance.
- Start the Power Head: Follow the starting procedures for your specific Greenworks string trimmer power head.
- Begin Blowing: Once the power head is running, direct the blower nozzle towards the debris you wish to clear. Use a sweeping motion to move leaves, grass clippings, and other light debris.
- Utilize Nozzles: Use the concentrator nozzle for stubborn or wet debris, or for directing airflow into tight spaces. Switch to the flared nozzle for clearing larger areas quickly.
- Adjust Speed (if applicable): If your power head has variable speed settings, adjust the speed as needed for different tasks. Lower speeds are suitable for delicate areas, while higher speeds provide maximum clearing power.
- Shut Down: When finished, turn off your string trimmer power head according to its manual.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your blower attachment.
- Cleaning: After each use, ensure the power head is off and the battery is removed. Clean the exterior of the blower attachment with a damp cloth. Remove any debris from the air intake vents and the blower tube to maintain efficient airflow.
- Inspection: Periodically inspect the blower tube and nozzles for cracks, damage, or excessive wear. Ensure all connections are secure.
- Storage: Store the blower attachment in a dry, clean area. Utilize the included wall hanging hook to store the attachment vertically, saving space and protecting it from damage.

Troubleshooting
If you encounter issues with your Greenworks HBA45 Horizontal Blower Attachment, consider the following common solutions:
- Reduced Airflow: Check the blower tube and nozzles for any obstructions. Ensure the air intake vents on the blower head are clear of debris.
- Attachment Not Secure: Verify that the blower attachment is fully inserted into the power head's coupling and that any locking mechanisms are properly engaged and tightened.
- Unit Not Starting: Ensure your string trimmer power head is functioning correctly. Check its power source (battery charged, cord connected, fuel present) and starting procedure. The blower attachment relies on the power head for operation.
If problems persist after attempting these steps, consult your string trimmer power head's manual or contact Greenworks customer support.
