# Example applications (see figures A–G)

Images of example applications can be found on the graphics pages.

The distance between the nozzle and the workpiece depends on the material you are working on (metal, plastic etc.) and the intended working method.

The optimum temperature for each application can be determined by a practical test.

Always test the amount of air and temperature first. Start at a greater distance and a lower power setting. Then adjust the distance and power setting according to requirements.

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 accessories. However, using the recommended accessories will simplify the work and considerably increase the quality of the result.

You can use all nozzles that are available as accessories from Bosch with this heat gun.

- Take care when changing the nozzle. Do not touch the 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.

To cool down faster, you can also let the heat gun run briefly at the lowest temperature that can be set.

##

Attach the surface nozzle (14). 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 adhesives, you can break connections or remove excess adhesive.

##

- The glass protection nozzle (15) 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 suitable spatula and brush it off with a soft wire brush.

##

- Before 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 circumstances be heated.

Attach the angle nozzle (16). 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 connections to avoid causing damage.

##

Attach the reflector nozzle (17). 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.

##

Fit the reducing nozzle (20) and the welding shoe (19). The workpiece requiring welding and the welding wire (18) must be made from the same material (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.

##

For spot welding, fit the reducing nozzle (20); for welding pipes, fit the reflector nozzle (17).

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.

##

Attach the reflector nozzle (17). Choose the diameter of the heat shrink plastic tube (21) suitable for the workpiece. Evenly heat the heat shrink plastic tube until it fits closely against the workpiece.
