Normal Operation
To switch from programming operation to normal
operation, press the program-selection button 6
as often as required until no program number is
indicated above the temperature in the display.
The air flow and temperature can be changed an-
ytime with the air-flow control button 8 and the
temperature-control button 9.
Under the following conditions, the values for air
flow and temperature set in normal operation
will remain stored:
– When changing to programming operation,
– When changing to the cool-air stage,
– When switching the power tool off.

Working Advice

Note: Do not apply the nozzle 4 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 5 can be removed when
working at particularly hard-to-reach locations.
Be careful of the hot nozzle! Increased dan-
ger of burning exists when working without
the heat protection collar.
To remove or mount the heat protection collar 5,
switch the power tool off and allow it to cool
down.
To cool down the power tool more quickly, you
can operate it for a few moments in the cool-air
stage.
Turn the heat protection collar 5 in anticlockwise
direction to remove and in clockwise direction to
mount again.
Placing Down the Power Tool (see figure C)
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.

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
the material characteristics. The distance be-
tween the nozzle and the workpiece depends on
the material to be worked.
The optimal temperature for the respective appli-
cation can be determined by practical testing.
Always start with a low temperature setting.
All application examples can be performed
without accessories except for "Removing Var-
nish/Paint from Windows". However, the use of
recommended accessories simplifies the work
and significantly improves the quality of the
result.
Be careful when changing the nozzle! Do not
touch the hot nozzle. Allow the power tool to
cool down and wear protective gloves while
changing the nozzle. Danger of burning one-
self on the hot nozzle.
Removing Varnish/Softening Adhesives
(see figure A)
Mount the wide jet nozzle 11 (accessory). Briefly
soften the varnish applying hot air and remove it
using a sharp, clean scraper or putty knife. Apply-
ing heat too long will burn the varnish, making it
more difficult to remove.
Many adhesives (e.g. of stickers) become soft
when heated. Heated adhesives allow for bonds
to be separated or excessive adhesive to be re-
moved.
Removing Varnish/Paint from Windows
(see figure B)
Use of the glass protection nozzle 12
(accessory) is essential. Danger of glass
breaking.
On profiled surfaces, varnish can be removed us-
ing an appropriately fitting spatula and brushed
off with a soft wire brush.
