Removing varnish/loosening adhesives (see figureA)

Fit the surface nozzle(6) (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)

uThe glass protection nozzle (7) (accessory) must be

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)

uBefore applying heat to the pipe, check it is in fact a

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(8) (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(9) (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.

Welding plastic (see figureE)

Fit the reducing nozzle (12) and the welding shoe(11) (both

accessories). The workpiece requiring welding and the weld-

ing wire(10) (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(10) 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 (12); for welding

pipes, fit the reflector nozzle(9) (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G)

Fit the reflector nozzle(9) (accessory). Choose the diameter

of the heat shrink plastic tube (13) (accessory) suitable for

the workpiece. Evenly heat the heat shrink plastic tube until

it fits closely against the workpiece.
