Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On
GHG 500-2: Press the On/Off switch 4 to posi-
tion I or II.
GHG 600-3: Press the On/Off switch 4 to posi-
tion I, II or III.
GHG 630 DCE: Press the On/Off switch 5 to po-
sition I, II or III.
Thermal-protection shut-off: In case of over-
heating (e.g. due to air build-up), the power tool
automatically shuts off the heating system, but
the blower will continue to run. When the power
tool has cooled down to the operating tempera-
ture, the heating system is automatically
switched on again.
Switching Off
GHG 500-2/GHG 600-3: Press the On/Off
switch 4 to position 0.
GHG 630 DCE: Press the On/Off switch 5 to po-
sition 0.
GHG 600-3/GHG 630 DCE: After working for a
longer time with high temperature, allow the
power tool to cool down by running it in the cold
air setting I before switching off.
Setting the Air Flow and Temperature
(GHG 500-2/GHG 600-3)
With the On/Off switch 4, you can select be-
tween different air flows and temperature com-
binations:

I 240 300
II 450 500
III – –

GHG 600-3: The cold air setting I is suitable for
cooling a warmed workpiece or for drying of
paint. It is also suitable for cooling the power tool
before placing it down or when changing nozzles.
Regulating the Air flow (GHG 630 DCE)
With the On/Off switch 5, you can regulate the
air flow in three steps:
Setting
I
II
III
As an example, reduce the air flow when the sur-
rounding area of a workpiece is not to be heated
excessively or when a light workpiece could be
moved away by the air flow.
In the cold air setting I, the temperature is fixed
at 50 °C; in the hot air settings II and III, the
temperature can be continuously regulated.
Setting the Temperature (GHG 630 DCE)
The temperature can only be regulated in the
hot air settings II and III. In the cold air setting
I, the temperature is fixed at 50°C.
When switching from the cold air setting I to one
of the hot air settings, the last set target temper-
ature is indicated for approx. 3 seconds be-
tween flashing arrows on display 7. The target
temperature is the same for both hot air steps II
and III, and does not change when switching be-
tween the two steps.
To increase the temperature, press on the "+" of
the temperature-control button 6, to decrease
the temperature, press on the "–".
Briefly pressing the temperature-control button

pressing of the temperature-control button con-

ture by 10 °C, until the button is released or the
maximum or minimal temperature is reached.
