Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To switch on the power tool, press the On/Off
switch 4 to position I or II.
To switch off the power tool, press the On/Off
switch 4 to the 0 position.
Selecting the Air-volume Level
With the On/Off switch 4 it is possible to select
between two air-volume levels:
Hot-air level I: 350 l/min
Hot-air level II: 550 l/min
A reduced air-volume level may be required in
certain cases, e.g., to avoid overheating the
workpiece surroundings or to avoid displacing
the workpiece if the air jet is too strong.
A higher air-volume level heats up the workpiece
more quickly and the hot-air gun can be held at
a greater distance from the workpiece.
Setting the Temperature
Infinitely variable temperature control of the air
jet is possible with the thumbwheel 3.
The marked thumbwheel positions correspond
with the following temperature ranges:

Working Advice

Note: Do not apply the nozzle 1 too close to the
workpiece being worked. The hot air build-up
can lead to overheating of the power tool.
Removing the Heat Protection
The heat protection collar 2 can be removed
when working at particularly hard-to-reach loca-
tions.
To remove or mount the heat protection collar 2,
switch the power tool off and allow it to cool
down.
Turn the heat protection collar 2 in anticlock-
wise direction to remove and in clockwise direc-
tion to mount again.
Placing Down the Power Tool
To cool down the power tool or have both hands
free, place it down on the standing surface 5.
Work Examples
The illustrations of the work examples can be
found on the fold-out pages.
The temperature settings in the work examples
are reference values that can vary, depending on
Temperature in °C
the material characteristics. The distance be-
100–120
tween the nozzle and the workpiece depends on
the material to be worked.
210–250
The optimal temperature for the respective ap-
300–340
plication can be determined by practical testing.
420–450
Always start with a low temperature setting.
500–550
All application examples can be performed
without accessories except for "Removing Var- 570–600
nish/Paint from Windows". However, the use of
recommended accessories simplifies the work
and significantly improves the quality of the re-
sult.
Before any work on the machine itself,
pull the mains plug.
Be careful of the hot nozzle! Increased dan-
ger of burning exists when working without
the heat protection collar.
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.
