Introduction
The Hammersmith Bionic Burner is an innovative hot air weed killer designed to effectively and permanently eliminate weeds using a 650°C hot air jet. This method destroys the cellular structure of the weeds, ensuring long-term results without the need for gas cartridges or chemical substances. Its unique design includes guide wheels for easy maneuverability and a conical nozzle for precise application. This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your Bionic Burner.

- Attach the handle to the telescopic pole.
- Securely attach the main unit to the telescopic pole.
- Attach the guide wheels to the main unit if desired for easier maneuverability during weed killing.
- Select the appropriate nozzle (conical for weeding, flat for other uses) and attach it firmly to the hot air outlet.
- Positioning the Stand: Unfold the integrated stand to allow the device to rest securely when not in use or during cooling.
Operating Instructions
Weed Killing Operation
- Preparation: Ensure the device is properly assembled and connected to a suitable power outlet (2000W).
- Power On: Switch on the device. The heating element will reach its operating temperature of 650°C in less than 1 minute.
- Application:
- Position the conical nozzle directly over the weed.
- If using the guide wheels, roll the device slowly over the weeds, ensuring the nozzle maintains the ideal distance from the ground.
- Apply the hot air jet to the weed for a few seconds. The goal is to heat the plant abruptly, destroying its cellular structure, not necessarily to burn it to ash.
- Even if the leaves remain green initially, the weed's internal structure will be damaged, leading to its death within hours.
- Post-Treatment: After a few hours, the treated weeds can be easily swept away.

Other Applications (with Flat Nozzle)
The Hammersmith Bionic Burner can also be used for other tasks:
- Grill and Fireplace Lighter: Use the flat nozzle to quickly ignite charcoal or wood. Direct the hot air stream onto the fuel until it catches fire.
- Paint and Varnish Removal: The hot air can soften old paint and varnish, making it easier to scrape off. Exercise extreme caution to avoid overheating surfaces or creating hazardous fumes.

Maintenance
- Cleaning: After each use, ensure the device is unplugged and completely cooled. Wipe the exterior with a damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Nozzle Care: Periodically check the nozzles for any debris or blockages. Clean as necessary, ensuring the device is cool.
- Storage: Store the Bionic Burner in a dry, cool place, away from direct sunlight and out of reach of children. Use the foldable stand for stable storage.
- Cord Inspection: Regularly inspect the power cord for any signs of damage. If damaged, do not use the device and contact customer support.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | No power supply; faulty power cord; device switch off. | Check power outlet and connection; inspect power cord for damage; ensure device switch is in the 'ON' position. |
| Hot air output is weak. | Blocked nozzle; insufficient power. | Ensure device is cool, then check and clear any blockages in the nozzle; ensure power supply meets specifications. |
| Weeds are not dying effectively. | Insufficient exposure time; incorrect distance from weed. | Increase exposure time slightly (a few seconds per weed); ensure the nozzle is at the optimal distance, using guide wheels if applicable. |
| Device overheats. | Prolonged continuous use; blocked air vents. | Allow the device to cool down; ensure air vents are clear and not obstructed. |
