The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
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.
Regulating temperature (GHG 20-63)
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
u
long for the heat gun to cool down.
The cooling stage is suitable for cooling down a heated work-
piece or for drying paint. It is likewise suitable for cooling
down the heat gun before turning off or replacing the attach-
ment nozzles.
Regulating airflow (GHG 23-66)
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 com-
binations (see "Saving Airflow/Temperature Combinations
(GHG 23-66)", page 14).
The set airflow is displayed with the ten bar segments (9) at
the lower edge of the display.

Work stage
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 de-
l/min °C
crease the airflow, press −.

If you wish to adjust the temperature again using the
150–300 50–630
(12) button, press the fan button (10) again. The fan
symbol (8) in the display stops flashing.
300–500 50–630
When you switch from the cooling stage to the work stage,
the airflow/temperature combination set is the one most re-
cently 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.
Regulating temperature (GHG 23-66)
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 com-
binations (see "Saving Airflow/Temperature Combinations
(GHG 23-66)", page 14).
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
u
long for the heat gun to cool down.
The cooling stage is suitable for cooling down a heated work-
piece or for drying paint. It is likewise suitable for cooling
down the heat gun before turning off or replacing the attach-
ment nozzles.
Saving Airflow/Temperature Combinations (GHG 23-66)
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.
