The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Noise/vibration information

Typically, the A-weighted sound pressure level of the heat
gun is less than 70 dB(A).

Operation

Starting operation

Pay attention to the mains voltage. The voltage of the
u
electricity source must agree with the specifications on
the type plate of the heat gun.
Creation of Smoke During Initial Use
A coating protects the metal surfaces from corrosion ex-
works. This protective layer evaporates during initial use.
The heat gun may display discolourations on the nozzle (1)
due to the production process. These do not count as dam-
age; the functioning of the heat gun is not affected.
Switching On
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 auto-
matically switched on again.
Switching Off
Slide the on/off switch (4) downwards into the 0 position.
After a sustained period of work at a high temperat-
u
ure, let the heat gun cool down before switching off.
To do this, allow it to run on the lowest temperature
setting for a short while.
Regulating airflow (GHG 20-63)
With the on/off switch (4), you can set the airflow to one of
several different levels:

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.
u
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
l/min °C
(GHG 23-66)", page 14).
