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 3.
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 figures of the application examples can be
found on the graphics 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 ap-
plication can be determined by practical testing.
Always start with a low temperature setting.
All application examples can be performed with-
out 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 oneself on the hot nozzle.
Removing Varnish/Softening Adhesives
(see figure A)
Mount the wide jet nozzle 8 (accessory). Briefly
soften the varnish applying hot air and remove it
using a sharp, clean scraper or putty knife. Ap-
plying heat too long will burn the varnish, mak-
ing 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 9 (acces-
sory) is essential. Danger of glass breaking.
On profiled surfaces, varnish can be removed
using an appropriately fitting spatula and
brushed off with a soft wire brush.
Shaping Plastic Tubing (see figure C)
Mount the reflector nozzle 10 (accessory). To
avoid kinking of the tubing, fill the tubing with
sand and plug both ends. Heat the tubing evenly
by by applying the heat from side to side.
Welding Plastics (see figure D)
Mount the reduction nozzle 13 and the welding
shoe 12 (both accessories). The workpieces to
be welded and the welding rod 11 (accessory)
must be of the same material (e.g. both of PVC).
The seam must be clean and grease-free.
Carefully heat up the seam location until it be-
comes doughy. Please note that the tempera-
ture difference between the doughy and liquid
state of plastic is low.
Feed in the welding rod 11 and allow it to run in-
to the gap so that a uniform bead is produced.
Shrinking (see figure E)
Mount the reduction nozzle 13 (accessory).
Select the diameter of the heat-shrinkable
sleeve 14 (accessory) according to the work-
piece (e.g. a cable lug). Heat the heat-shrinkable
sleeve evenly.
Defrosting Water Pipes (see figure F)
Before heating pipes, check to make sure
that it is actually a water pipe. Water lines
often do not differ in appearance from gas
lines. Gas lines are not to be heated under
any circumstances.
Place on the angle nozzle 15 (accessory). Heat
the frozen zone always from the outside to the
middle.
Heat up plastic pipes as well as connections be-
tween pipe pieces especially careful to prevent
damage.
