Operation
Starting Operation
 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
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 2 forwards.
To save energy, only switch the power tool on when using it.
Switching Off
Slide the on/off switch 2 backwards into the 0 position.
 After working at high temperatures for a prolonged pe-
riod, let the power tool cool down before switching it
off. To do this, allow it to run on the lowest temperature
setting for a short while.

Regulating the Air flow
With the on/off switch 2 you can set the airflow to one of
several different levels:
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
You can control the temperature of the airflow using the
setting wheel 5

Setting wheel position 1 is suitable for cooling down a heated
workpiece or for drying paint. It is also suitable for cooling
down the power tool before putting it down or changing the
attachment nozzles.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
Note: Do not apply the nozzle 3 too close to the workpiece be-
ing worked. The hot air build-up can lead to overheating of the
power tool.
Removing the Heat Protection
When working in particularly tight spaces, you can remove the
heat shield 4 by turning it.
 Be careful of the hot nozzle! Increased danger of burning
exists when working without the heat protection collar.
To remove or mount the heat protection collar 4, switch the
power tool off and allow it to cool down.
To speed up the cooling, the power tool can also be operated
for a short period with the lowest adjustable temperature.
Placing Down the Power Tool (see figures D and G)
To cool down the power tool or have both hands free, place it
down on the standing surface 1.
 Be especially careful when working with the placed
down power tool! There is danger of burning oneself on
the hot nozzle or on the hot air jet.
