# Starting operation

- Remove the rechargeable battery before changing accessories or storing the heat gun. This safety measure prevents the heat gun from being started accidentally.

##

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 (1) due to the production process. These do not count as damage; the functioning of the heat gun is not affected.

##

To switch on the on/off switch (5), slide upwards. The heat gun starts in the energy-efficient standard setting (350 °C), which is suitable for most short-term applications.

##

Briefly pressing the boost button (4) activates the energy-intensive high temperature setting (450 °C). Pressing the boost button (4) again switches back to the standard setting once more.

If the heat gun is switched off when the high temperature setting is activated, it automatically restarts in the standard setting.

##

To switch off, slide the on/off switch (5) down.

Switch off the heat gun at the rechargeable battery (3) to allow it to cool down.

Ensure here that the nozzle (1) and the ventilation slots of the heat gun are not covered.

##

If the rechargeable battery (3) is removed while the heat gun is in operation and the heat gun is still switched on when it is reinserted, the restart protection will activate. The heat gun does not start.

Switch the heat gun off at the on/off switch (5) and then switch it on as usual.

##

If the rechargeable battery (3) gets too hot during operation, the output is reduced.

If the heat gun continues to be operated and the temperature in the rechargeable battery increases further, the heat gun will switch itself off.
