Introduction
This instruction manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your DEWALT D26414-QS 2000W Heat Gun. Please read this manual thoroughly before using the tool and keep it for future reference.
General Safety Instructions
WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
- Personal Safety: Always wear eye protection. Use personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection when appropriate. Stay alert, watch what you are doing, and use common sense when operating a power tool.
- Heat Gun Specific Safety:
- Do not direct the hot air stream at people or animals.
- Do not use the heat gun near flammable materials or gases.
- Allow the tool to cool down completely before storing.
- Ensure adequate ventilation when working, especially when stripping paint, as toxic fumes may be produced.
- Do not block the air inlet or outlet nozzles.
Setup
Unpacking
Carefully remove the heat gun and all accessories from the packaging. Inspect the tool for any damage that may have occurred during shipping. Do not discard packaging materials until you have confirmed all components are present and undamaged.
Attaching Nozzles
Your DEWALT D26414-QS heat gun comes with various nozzles for different applications, such as a conical nozzle and a fishtail nozzle. To attach a nozzle:
- Ensure the heat gun is unplugged and cool.
- Align the desired nozzle with the heat gun's outlet.
- Push the nozzle firmly onto the outlet until it is securely seated. Do not force it.

Power Connection
Connect the heat gun's power cord to a suitable 230V AC power outlet. Ensure the outlet is properly grounded and capable of supplying the required 2000W power.
Operating Instructions
Powering On/Off
To turn the heat gun on, slide the power switch to the desired airflow speed setting. To turn it off, slide the switch back to the '0' (off) position.
Temperature and Airflow Control
The DEWALT D26414-QS features a digital display for precise temperature control and two airflow speed settings.

- Temperature Adjustment: Use the '+' and '-' buttons located near the digital display to set the desired temperature. The temperature can be adjusted in 10°C increments, ranging from 50°C to 600°C. The display will show the set temperature and then the actual temperature as it heats up.
- Airflow Speed: The power switch typically has two positions for airflow speed (e.g., I and II). Position I provides lower airflow, and Position II provides higher airflow. Select the appropriate speed for your application.
- Memory Function: The heat gun can store your last used temperature setting for repetitive tasks.
Applications
The DEWALT D26414-QS heat gun is suitable for a variety of professional applications, including:
- Paint and varnish stripping.
- Bending and forming plastics.
- Shrinking heat-shrink tubing.
- Thawing frozen pipes.
- Softening adhesives.

Cool-Down Procedure
Unlike some other heat guns, the DEWALT D26414-QS is designed for professional use and does not typically require a prolonged cool-down period by running it at a low setting. However, for optimal tool longevity and safety, always ensure the tool is switched off and unplugged after use. Allow it to cool naturally in a safe, non-flammable area before storing.

Maintenance
Regular maintenance ensures the longevity and safe operation of your heat gun.
- Cleaning: Keep the air inlet and outlet vents clean and free from obstructions. Use a soft, dry cloth to wipe down the exterior of the tool. Do not use harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the power cord for any signs of damage, cuts, or fraying. Check the nozzles for any deformation or blockages. If any damage is found, discontinue use and have the tool serviced by qualified personnel.
- Storage: Store the heat gun in a dry, secure location out of reach of children and away from extreme temperatures. Ensure the tool is completely cool before storing.
