Product Description and
Specifications
Please observe the illustrations at the beginning of this oper-
ating manual.
Intended Use
The heat gun is intended for deforming and welding plastic,
removing coats of paint and heating heat shrink plastic
tubes. It is also suitable for soldering and tinning, melting ad-
hesive bonding and thawing water pipes.
The heat gun is intended for handheld, supervised use.

Operation
Starting operation
Pay attention to the mains voltage. The voltage of the
u
electricity source must agree with the specifications on
the type plate of the heat gun.
Creation of Smoke During Initial Use
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 dam-
age; the functioning of the heat gun is not affected.
Switching On
Slide the on/off switch (2) upwards.
Switching Off
Slide the on/off switch (2) downwards into the 0 position.
After a sustained period of work at a high temperat-
u
ure, 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.
Regulating airflow
With the on/off switch (2), you can adjust the airflow for
both work stages:
Reduce the airflow, for instance, if the area surrounding a
GHG 20‑60
workpiece cannot tolerate excessive heat or if a workpiece is
3 601 BA6 4.. light enough that the airflow might move it.

Controlling temperature
l/min 150–300 You can control the temperature of the airflow using the
l/min 300–500 thumbwheel (5) .
The positions marked on the thumbwheel correspond to the
