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

tool is less than

Operation
Starting Operation
u
Pay attention to the mains voltage.
The voltage of the
power source must match the voltage specified on the
rating plate of the power tool.
Creation of Smoke During Initial Use
A coating protects the metal surfaces from corrosion ex-
works. This protective layer evaporates during initial use.
Switching On
Slide the on/off switch
(4)
upwards.
Thermal protection shutdown:
If the power tool overheats
(e.g. due to a build-up of air), the heating system will auto-
matically switch off, though the blower will continue to run.
Once the power tool has cooled back down to its operating
temperature, the heating system will automatically switch on
again.
Switching Off
Slide the on/off switch
(4)
downwards into the
0
position.
u
After working at high temperatures for a prolonged
period, let the power tool cool down before switching
it off. To do this, allow it to run on the lowest temper-
ature 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:
Airflow setting
l/min
°C
150
50
150–300
50–630
300–500
50–630
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)
On the lowest airflow setting, the temperature is set to
50 °C. In the other two airflow settings, the temperature can
be adjusted.
When switching from the lowest airflow setting to another
setting, the temperature last set is called up again.
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 three
seconds. The actual temperature at the nozzle output is dis-
played 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.
