2. Safety Information
Please read and understand all safety warnings and instructions before using this product. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- General Safety: Always keep the air outlet open and maintain a proper distance from the object being heated to prevent overheating and potential fire hazards.
- Overheating Protection: The heat gun features a built-in overheating protection device that automatically cuts off the circuit if the temperature exceeds safe limits. Allow the unit to cool down if this occurs.
- Cool Down Procedure: After use, before completely shutting down the machine, switch to the lower temperature setting (Mode I) and allow it to blow air for a short period to reduce the internal temperature. This extends the service life of the heat gun.
- Ventilation: Use the heat gun in a well-ventilated area.
- Flammable Materials: Do not use the heat gun near flammable liquids, gases, or materials.
- Electrical Safety: Ensure the power supply matches the voltage requirements (110 Volts). Do not expose the heat gun to rain or wet conditions. Do not abuse the cord.
- Personal Protection: Wear appropriate personal protective equipment, such as heat-resistant gloves and eye protection, when operating the heat gun.
- Storage: Store the heat gun in a dry, secure place out of reach of children when not in use.

6. Operating Instructions
The KAIWEETS Mini Heat Gun offers two temperature settings for optimal performance across various tasks:
- Mode I (Low Temperature):
- Temperature: 250°C / 482°F
- Air Flow: 300 L/min
- Applications: Ideal for delicate processes such as shrink wrapping, removing bubbles from resin, drying watercolor paintings, and other tasks requiring lower heat.
- Mode II (High Temperature):
- Temperature: 450°C / 842°F
- Air Flow: 500 L/min
- Applications: Suitable for more demanding tasks like dry paint removal, soldering, and other applications requiring higher heat.
General Usage Steps:
- Select Mode: Use the switch on the handle to select the desired temperature mode (I or II) based on your application.
- Power On: Turn the heat gun on. The heating element will quickly reach the selected temperature.
- Apply Heat: Direct the hot air stream towards the workpiece. Maintain a proper distance to avoid damaging the material. For shrink wrapping, move the heat gun evenly over the surface.
- Cool Down: Before turning off the heat gun completely, switch it to Mode I (lower temperature) and allow it to run for approximately 30-60 seconds. This helps dissipate residual heat and prolongs the life of the heating element.
- Power Off: Turn the heat gun off and unplug it from the power outlet.
- Storage: Allow the heat gun to cool down completely before storing it.

7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your heat gun:
- Cleaning: After each use, ensure the heat gun is unplugged and completely cool. Wipe the exterior with a clean, damp cloth. Do not use abrasive cleaners or solvents.
- Air Vents: Keep the air intake and outlet vents clear of dust and debris. Use a soft brush or compressed air to clean them if necessary.
- Cord Care: Regularly inspect the power cord for cuts, fraying, or damage. Do not use the heat gun if the cord is damaged. Store the cord neatly without sharp bends.
- Storage: Store the heat gun in a dry, clean environment, away from direct sunlight and extreme temperatures. Utilize the retractable stand for stable storage.
