Removing varnish/loosening adhesives(see figure A)
Fit the surface nozzle (14) (accessory). Briefly soften the
varnish 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 (15) (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 (16) (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 (17) (accessory). Fill plastic pipes
with sand and seal them on both sides to prevent the pipe
bending. Carefully and evenly heat the pipe by moving the
tool back and forth from one side to the other.
Welding plastic (see figure E)
Fit the reducing nozzle (20) and the welding shoe (19) (both
accessories). The workpiece requiring welding and the weld-
ing wire (18) (accessory) must be made from the same ma-
terial (e.g. both PVC). The seam must be clean and free from
grease.
Heat the point of the seam carefully until it becomes pliable.
Note that there is not a great difference in temperature
between pliable plastic and liquid plastic.
Apply the welding wire (18) and allow it to flow into the joint
to form an even bead.
Soft Soldering (see figure F)
For spot welding, fit the reducing nozzle (20); for welding
pipes, fit the reflector nozzle (17) (both accessories).
If you are using solder without flux, apply soldering grease or
paste to the solder joint. Depending on the material, heat the
solder joint for approx. 50 to 120 seconds. Apply the solder.
The solder must be melted by the temperature of the work-
piece.
If necessary, remove the flux after the solder joint has cooled
down.
Heat-shrinking (see figure G)
Fit the reflector nozzle (17) (accessory). Choose the dia-
meter of the heat shrink plastic tube (21) (accessory) suit-
1 609 92A 4RE | (26.10.2018)
able for the workpiece. Evenly heat the heat shrink plastic
tube until it fits closely against the workpiece.
