Starting operation
- Pay attention to the mains voltage. The voltage of the electricity source must agree with the specifications on the type plate of the heat gun.
Slide the on/off switch (4) upwards.
Thermal protection regulation: Upon overheating (e.g. due to an air blockage or not enough air being supplied), the heat gun switches off the heating automatically and the thermal protection regulation symbol (7) appears on the display. The blower, however, will continue to run. If the heat gun has cooled down to operating temperature, the heating is automatically switched on again.
With the on/off switch (4), you can set the airflow to one of several different levels:
Setting | Switch position | l/min | °C |
|---|---|---|---|
Cooling stage |
| 150 | 50 |
Work stage 1 |
| 150–300 | 50–630 |
Work stage 2 |
| 300–500 | 50–630 |
The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Reduce the airflow, for instance, if the area surrounding a workpiece cannot tolerate excessive heat or if a workpiece is light enough that the airflow might move it.
In the cooling stage, the temperature is set at 50 °C. In both work stages, the temperature can be regulated.
Upon switching from the cooling stage to one of the work stages, the temperature set there most recently is recalled.
The set temperature is shown in the display (13).
To increase the temperature, press + on the (12) button; to decrease the temperature, press −.
Briefly pressing the (12) button increases or decreases the temperature by 10 °C. Pressing and holding down the button continuously increases or decreases the temperature by 10 °C until the button is released or the maximum/minimum temperature is reached.
The set target temperature is shown in the display for 3 s. The actual temperature at the nozzle output is displayed and the unit of measure for the temperature (6) flashes until the target temperature is reached. The unit of measure for the temperature stops flashing once the target temperature is reached.
- When you reduce the temperature, it does not take long for the heat gun to cool down.
The cooling stage is suitable for cooling down a heated workpiece or for drying paint. It is likewise suitable for cooling down the heat gun before turning off or replacing the attachment nozzles.
In the cooling stage, you can set the airflow in 10 steps between 150 and 300 l/min. In the work stage, you can set the airflow in 10 steps between 150 and 500 l/min.
Alternatively, you can use saved airflow/temperature combinations see Saving Airflow/Temperature Combinations (GHG 23-66).
The set airflow is displayed with the ten bar segments (9) at the lower edge of the display.
Setting | Switch position | l/min | °C |
|---|---|---|---|
Cooling stage |
| 150−300 | 50−100A) |
Work stage |
| 150−500 | 50−650 |
- A)
The temperature is automatically set in the range of 50−100 °C, depending on the selected air current.
To adjust the airflow, first press the fan button (10). The fan symbol (8) in the display flashes. The airflow can now be regulated with the airflow control button (12).
To increase the airflow, press + on the (12) button; to decrease the airflow, press −.
If you wish to adjust the temperature again using the (12) button, press the fan button (10) again. The fan symbol (8) in the display stops flashing.
When you switch from the cooling stage to the work stage, the airflow/temperature combination set is the one most recently used in the work stage.
Reduce the airflow, for instance, if the area surrounding a workpiece cannot tolerate excessive heat or if a workpiece is light enough that the airflow might move it.
In the cooling stage, the temperature is automatically set between 50 °C and 100 °C. In the work stage, you can set the temperature between 50 °C and 650 °C.
Alternatively, you can use saved airflow/temperature combinations see Saving Airflow/Temperature Combinations (GHG 23-66).
The set temperature is shown in the display (13).
To increase the temperature, press + on the (12) button; to decrease the temperature, press −.
Briefly pressing the (12) button increases or decreases the temperature by 10 °C. Pressing and holding down the button continuously increases or decreases the temperature by 10 °C until the button is released or the maximum/minimum temperature is reached.
The set target temperature is shown in the display for 3 s. The actual temperature at the nozzle output is displayed and the unit of measure for the temperature (6) flashes until the target temperature is reached. The unit of measure for the temperature stops flashing once the target temperature is reached.
- When you reduce the temperature, it does not take long for the heat gun to cool down.
The cooling stage is suitable for cooling down a heated workpiece or for drying paint. It is likewise suitable for cooling down the heat gun before turning off or replacing the attachment nozzles.
You can save 4 airflow/temperature combinations or have access to 4 saved combinations ex works.
For this, the on/off switch (4) must be at the work stage.
Factory settings | |||

To call up a combination, keep pressing the memory button (11) until the number you want appears in the display (5).
To save your own combination:
- Press the memory button (11) to select the memory preset you want.
- Set the desired temperature and airflow. The memory preset (5) flashes to indicate that the saved combination has been changed.
- Press and hold down the memory button (11). The memory preset (5) flashes for approx. 2 s. When it lights up continuously, the new combination has been saved.
