Bosch Professional GHG 16-50 Original Instructions Manual page 8

8 | English
If you are unsure what material you are working on or what
effect the hot air might have on it, first test the effect on a
concealed area.
All example applications apart from "Stripping paint from
window frames" can be carried out without the use of ac-
cessories. However, using the recommended accessories
will simplify the work and considerably increase the quality
of the result.
Take care when changing the nozzle. Do not touch the
u
nozzle while it is hot. Let the heat gun cool down and
wear protective gloves during changeover. The heat
from the nozzle can cause burns.
Removing varnish/loosening adhesives (see figure A)
Fit the surface nozzle (4) (accessory). Briefly soften the var-
nish with hot air and remove it with a clean spatula. Long
heat exposure burns the varnish and makes removal more
difficult.
Many adhesives can be softened using heat. By heating ad-
hesives, you can break connections or remove excess adhes-
ive.
Stripping paint from window frames (see figure B)
The glass protection nozzle (5) (accessory) must be
u
used for this application. There is a risk that the glass
may break.
You can remove the paint from profiled surfaces with a suit-
able spatula and brush it off with a soft wire brush.
Thawing frozen water pipes (see figure C)
Before applying heat to the pipe, check it is in fact a
u
water pipe. Water pipes and gas pipes often look
identical from the outside. Gas pipes must under no cir-
cumstances be heated.
Fit the angle nozzle (6) (accessory). Gradually heat the
frozen points of the pipe, starting at the outlet and moving
back towards the inlet.
Take great care when warming plastic pipes and pipe con-
nections to avoid causing damage.
Shaping plastic pipes (see figure D)
Fit the reflector nozzle (7) (accessory). Fill plastic pipes with
sand and seal them on both sides to prevent the pipe bend-
ing. Carefully and evenly heat the pipe by moving the tool
back and forth from one side to the other.
Soft Soldering (see figure E)
For spot welding, fit the reducing nozzle (8); for welding
pipes, fit the reflector nozzle (7) (both accessories).
If you are using solder without flux, apply soldering grease or
paste to the solder joint. Heat the solder joint and apply the
solder. The solder must be melted by the temperature of the
workpiece.
If necessary, remove the flux after the solder joint has cooled
down.
Heat-shrinking (see figure F)
Fit the reflector nozzle (7) (accessory). Choose the diameter
of the heat shrink plastic tube (9) (accessory) suitable for
1 609 92A 738 | (01.12.2021)
the workpiece. Evenly heat the heat shrink plastic tube until
it fits closely against the workpiece.
