4. Setup and First Use
4.1 Butane Refilling
- Ensure the lighter is completely empty of any residual fuel by pressing the refill valve with a small tool (e.g., a screwdriver).
- Turn the flame adjuster to the lowest setting (towards the '-' sign).
- Hold the lighter upside down. Firmly insert the nozzle of a high-quality butane fuel can into the filling valve at the bottom of the lighter.
- Press down for 3-5 seconds. Repeat 2-3 times until the fuel window indicates approximately 85% full.
- Allow the lighter to rest for about 4 minutes after refilling to allow the fuel to reach room temperature.

Refilling Process: Insert the butane can nozzle vertically into the lighter's refill valve and press firmly.

4.2 Flame Adjustment
The flame height can be adjusted using the adjuster at the bottom of the lighter. Gently pull up the recessed semi-circular handle and turn it towards '+' for a higher flame or towards '-' for a lower flame. The recommended flame height is 0.8-1.0 inch.

Adjustable Flame Control: The diagram illustrates how to adjust the flame intensity by rotating the valve at the base of the lighter.
5. Operating Instructions
5.1 Igniting the Lighter
Once filled and adjusted, slide the ignition button forward to ignite the jet flame. The flame will appear instantly.
5.2 Turning Off the Lighter
Release the ignition button to extinguish the flame. The flame will cease immediately once the button is released.
6. Maintenance
6.1 General Care
- Keep the lighter clean and free from debris.
- Store in a cool, dry place, away from direct sunlight and heat sources.
6.2 Refilling Best Practices
- Always use high-quality butane fuel to ensure optimal performance and longevity of the lighter.
- Do not attempt to disassemble the lighter for maintenance beyond refilling and flame adjustment.
7. Troubleshooting
7.1 Lighter Does Not Ignite
- Check Butane Level: Look at the visible fuel window. If empty, refill the lighter.
- Adjust Flame Height: Ensure the flame adjuster is not set too low. Increase it slightly.
- Bleed Air: If the lighter has been refilled but still won't light, there might be air trapped in the tank. Press the refill valve with a small tool to release air, then try refilling again.
7.2 Flame is Weak or Inconsistent
- Low Butane: Refill the lighter if the fuel level is low.
- Flame Adjustment: Increase the flame height using the adjuster.
- Impurity in Fuel: Use only high-quality butane fuel. Low-quality fuel can cause blockages or inconsistent flames.
