4. Setup
- Prepare Work Area: Ensure the work area is clean, free of flammable materials, and well-ventilated.
- Connect Gas Supply: Carefully attach the torch's gas inlet connector to a compatible LPG gas cylinder or hose. Ensure the connection is secure and hand-tightened. Do not overtighten.
- Check for Leaks: Before opening the gas valve, apply a leak detection solution (soapy water) to all connections. Slowly open the gas valve on the cylinder. If bubbles appear, close the gas valve immediately and re-tighten the connection. Repeat until no bubbles are observed.
- Position Torch: Adjust the swivel connection to the desired angle for your application.
5. Operating Instructions
- Ignition:
- Ensure the gas supply is open and the torch's gas control valve (if present) is slightly open.
- Using a spark lighter or striker, ignite the gas at the burner tubes. Do not use matches or cigarette lighters.
- Adjust the gas control valve to achieve the desired flame size and intensity. The cyclone burner is designed for high heat output.
- Operation:
- Direct the flame towards the workpiece, maintaining a safe distance.
- Monitor the flame and adjust as needed.
- Extinguishing:
- Close the gas control valve on the torch completely.
- Close the main gas valve on the cylinder.
- Allow the torch to cool down naturally in a safe, non-flammable area.
6. Maintenance
- Cleaning: Keep the burner tubes and gas inlet free from dirt and debris. Use a soft cloth to wipe down the exterior of the torch. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the torch for any signs of damage, wear, or leaks. Pay close attention to the gas connections and burner tubes.
- Storage: Store the torch in a cool, dry place, away from direct sunlight and sources of ignition. Ensure the gas cylinder is disconnected and stored separately according to its manufacturer's instructions.
- Parts: Information regarding spare parts availability is not provided. Contact Rothenberger customer support for assistance.
