The target temperature can be increased in steps of
10 °C by pressing the "+" side of the temperature but-
ton 4 or reduced by pressing the "–" side of the button
4. Brief pressing of the button increases or decreases
the target temperature one time by 10 °C. Longer
pressing of the button increases or decreases the
temperature continuously by 10 °C steps until the but-
ton is released or the minimum or maximum tempera-
ture is reached.
In the blower step I, the pre-set temperature is 50 °C.
When switching from blower step II or III with higher
temperatures to blower step I, a short time is required
until the unit has cooled to 50 °C. During the cooling
period, the display 5 shows the actual temperature at
the nozzle outlet.
Working Instructions
Removing the Heat Protector
For working in especially narrow places, the heat pro-
tector 2 can be removed.
Be careful of the hot nozzle! Increased danger
s
of burning exists when working without the heat
protector.
To remove or mount the heat protector, the unit must
be switched off and have cooled. For cooling, run
briefly in the cold setting, if necessary.
Turn the heat protector 2 counter clockwise to remove
and clockwise to mount again.
Placing Down the Unit
For cooling of the heated unit or to have both hands
free for working, the unit can be place down in the up-
right position on the rear housing surface (see Fig.
Be especially careful when working with the
s
upright unit! There is danger of burning on the hot
nozzle and the hot air stream.
Working Examples
The letters of the following application examples refer
to the illustrations on the fold-out page.
Temperature settings given in the application exam-
ples are suggested values that, depending on the ma-
terial characteristics, can deviate. The distance be-
tween the nozzle and work piece is dependent on the
material to be processed.
The ideal temperature should first be ascertained by
performing a test. Therefore, begin with a lower tem-
perature setting.

All application examples (except
without accessories. However, the use of the recom-
mended accessory parts simplify the work and signifi-
cantly improve the quality of the results.
Be careful when changing the nozzle, danger
s
of burning! Do not tough the hot nozzle. Allow
the unit to cool. Wear protective gloves.
Bosch stocks an extensive range of accessories (see
Bosch Accessories catalog) which offer a wide range
of other applications.
Additional information can be found in popular DIY
books.
Removing Paint/Softening Adhesives
A
Place on the wide nozzle 6. Soften the paint using hot
air and remove evenly using a spatula. Do not heat the
paint for too long since this will burn the paint, making
it more difficult to remove. The spatula should be kept
sharp and clean.
Many adhesives (e.g. stickers) become softer when
heated allowing adhesive bonds to be separated or
superfluous adhesive to be removed.
Removing Paint from Window Frames
B
Danger of glass breaking!
Use of the glass protection nozzle 7 is essential.
On profiled surfaces, paint can be removed using a
spatula and brushed off using a soft wire brush.
Shaping Plastic Tubing
C
Place on the reflector nozzle 8. To avoid kinking the
tubing, fill the tubing with sand and seal at both ends.
Heat the tubing evenly by moving it from side to side.
).
C
Welding Plastics
D
Place on the reduction nozzle 11 and the welding shoe
10. The materials to be welded and the welding rod 9
must be made of the same material (e.g. PVC with
PVC). The seam must be clean and grease-free.
Heat the welding seam until it becomes tacky. Please
note that the temperature difference between the
tacky and liquid state of a plastic is very small. Then
feed in the welding rod 9 and allow to run into the gap
so that a uniform bead is produced.
Shrink Fitting
E
Place on the reduction nozzle 11. Select the diameter
of the heat-shrink tubing 12 according to the work
piece, for example, a cable lug.
Heat the heat-shrinkable sleeve evenly.
