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 6 (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 7 (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 8 (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 11 and the welding
shoe 10 (both accessories). The workpieces to
be welded and the welding rod 9 (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 9 and allow it to run into
the gap so that a uniform bead is produced.

Shrinking (see figure E)
Mount the reduction nozzle 11 (accessory). Se-
lect the diameter of the heat-shrinkable sleeve
12 (accessory) according to the workpiece (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 13 (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.
