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 and Off
To switch on the power tool, push the On/Off
switch 3 to the position
page 17) or
(see "Hot-air Stage", page 17).
In both positions, the power tool will start with
the previous set air-flow and temperature values.
To switch off, push the On/Off switch 3 to the
stop in position "0".
After working for a longer period at a high tem-
perature, operate the power tool for a short pe-
riod in the cool-air stage
Thermal-protection shut-off: In case of overheat-
ing (e.g. due to air build-up), the power tool auto-
matically shuts off the heating system, but the

blower will continue to run. When the power tool
has cooled down to the operating temperature,
the heating system is automatically switched on
again.
Regulating the Air flow
The air flow can be regulated with the air-flow
control button 8:
To increase the air flow, press on the "+" of the
(see "Cool-air Stage",
air-flow control button 8, to decrease the air
flow, press on the "–".
Briefly pressing the air-flow control button 8 at
the respective position increases or decreases
the air flow by one step. Prolonged pressing of the
air-flow control button continuously increases or
decreases the air flow until the button is released,
or the maximum or minimal air flow is reached.
before switching off.
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.
