Operation

Starting Operation

Observe correct mains voltage! The voltage of the pow-
er 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 (see "Cool-air Stage", page 14) or (see "Hot-air
Stage", page 14).
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 temperature, oper-
ate the power tool for a short period in the cool-air stage
before switching off.
Thermal-protection shut-off: In case of overheating (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 temperature,
the heating system is automatically switched on again.
When not using the power tool, switch it off in order to save
energy.
Regulating the Air flow
The air flow can be regulated with the air-flow control button 8:
Minimal air flow
Maximum air flow
To increase the air flow, press on the "+" of the air-flow con-
trol 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. Pro-
longed pressing of the air-flow control button continuously in-
creases or decreases the air flow until the button is released,
or the maximum or minimal air flow is reached.

As an example, reduce the air flow when the surrounding area
of a workpiece is not to be heated excessively or when a light
workpiece could be moved away by the air flow.
Setting the Temperature
The temperature can only be regulated in the hot-air stage .
To increase the temperature, press on the "+" of the temper-
ature-control button 9, to decrease the temperature, press on
the "–".
Briefly pressing the temperature-control button 9 at the re-
spective position increases or decreases the temperature by
10 °C. Prolonged pressing of the temperature-control button
continuously increases or decreases the temperature by
10 °C, until the button is released or the maximum or minimal
temperature is reached.
After a change to the temperature setting, the power tool re-
quires a short period to warm up or cool down the air flow.
During this period, the target temperature is indicated be-
tween the flashing arrows in the display 7. When the target
temperature is reached, the arrows go out and the display in-
dicates the actual temperature.
Activating/Deactivating the Button Lock ("LOC")
To prevent accidental changing of the air flow and tempera-
ture the function of buttons 6, 8, 9 and 10 can be locked
when in the hot-air stage. In the cool-air stage
can be changed even when the button lock is activated.
Activating the Button Lock:
Switch the power tool on while in the hot-air stage . Adjust
the air-flow and temperature settings to be locked.
Switch the power tool off.
Press and hold the save button 10 and switch the power tool
on again (in cool-air or hot-air stage). The display 7 will indi-
cate "OFF" for the deactivated button lock.
With the save button 10 still held, press one after the other:
– "+" on the temperature-control button 9,
– "+" on the air-flow control button 8,
– "–" on the temperature-control button 9,
– "–" on the air-flow control button 8.
The display indicates "ON". Release the save button 10.
