# Starting operation

- Pay attention to the mains voltage. The voltage of the electricity source must agree with the specifications on the type plate of the heat gun.

##

A coating protects the metal surfaces from corrosion ex-works. This protective layer evaporates during initial use.

The heat gun may display discolourations on the nozzle (3) due to the production process. These do not count as damage; the functioning of the heat gun is not affected.

##

Slide the on/off switch (2) upwards.

##

Slide the on/off switch (2) downwards into the 0 position.

- After a sustained period of work at a high temperature, let the heat gun cool down before switching off. To do this, allow it to run on the lowest temperature setting for a short while.

##

With the on/off switch (2), you can adjust the airflow for both work stages:

Work stage | l/min | °C
--- | --- | ---
| 150–300 | 50–630
| 300–500 | 50–630

Reduce the airflow, for instance, if the area surrounding a workpiece cannot tolerate excessive heat or if a workpiece is light enough that the airflow might move it.

##

You can control the temperature of the airflow using the thumbwheel (5).

The positions marked on the thumbwheel correspond to the following temperature ranges:

Thumbwheel position | Temperature in °C
--- | ---
1 | 50–80
2 | 130–160
3 | 210–240
4 | 280–310
5 | 340–370
6 | 410–440
7 | 480–510
8 | 550–580
9 | 620–630

Thumbwheel position 1 is suitable for cooling down a heated workpiece or for drying paint. It is also suitable for cooling down the heat gun before switching it off or changing the attachment nozzles.
