The temperature can only be regulated in the
hot-air stage .
To increase the temperature, press on the
“+”

the temperature-control button
9
, to decrease
the temperature, press on the
“–”

at the respective position increases or de-
creases the temperature by 10 °C. Prolonged
pressing of the temperature-control button con-
tinuously increases or decreases the tempera-
ture 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 requires a short period to warm up
or cool down the air flow. During this period, the
target temperature is indicated between the
flashing arrows in the display
7
. When the target
temperature is reached, the arrows go out and
the display indicates the actual temperature.

Operating Modes
Cool-air Stage
The air flow can be regulated, the
temperature is set to 50 °C (cannot
be regulated), and programming op-
eration is not possible.
The cool-air stage is suitable for cooling down
a heated-up workpiece or for drying paint. It is
also suitable for cooling down the power tool
before placing it down or changing nozzles.
When changing from the hot-air stage with
higher temperatures, it will take a few moments
until the power tool has cooled down to 50 °C.
During cooling down, the display
7
indicates the
actual temperature at the nozzle outlet.
When changing from the hot-air stage to the
cool-air stage , the current air-flow settings
are taken over.
Hot-air Stage
The air flow and temperature can be
regulated; normal and programming
operation are possible.
When changing from the cool-air stage to the
hot-air stage , the air flow, temperature and
possibly the program are automatically adjusted
according to the settings of the last hot-air stage
operation.
