Typical Applications
Temperature settings given in the application examples are suggested values that, depending on the material characteristics, can deviate. The distance between the nozzle and workpiece is dependent on the material to be processed.
The ideal temperature should first be ascertained by performing a test. Therefore, begin with a lower temperature setting.
All application examples (except figure 5) can be performed without accessories. However, the use of the recommended accessories simplify the work and significantly improve the quality of the results.

not touch the hot nozzle. Allow the unit to cool. Wear protective gloves.
Bosch stocks a range of accessories (see Bosch catalog) which facilitate a wide range of other applications.
STRIPPING PAINT/SOFTENING ADHESIVES Attach the optional HG010 spreader nozzle. Soften the paint using hot air and remove evenly using a spatula. Do not heat the paint for too long since this will burn the paint, making it more difficult to remove (Fig. 4).

Many adhesives (e.g. stickers) become softer when heated allowing adhesive bonds to be separated or superfluous adhesive to be removed.
1.To strip paint, turn unit on and hold it about 1 inch from the surface being stripped. Proper distance and speed of stripping should be determined by experience. It is an advantage to hold the gun further from the surface and to move forward slowly. Slower speed is compensated by the wider softened areas. Heat will also penetrate deeper.
2.As paint begins to blister and bubble, move gun slowly in a steady progression across the surface. Follow closely with a scraping knife (a
a.Removal of paint by using heat is based on the fact that all organic paints soften at elevated temperatures. When soft, the paint can be easily lifted off without damage to the surface.
b.When stripping paint from grooves in moldings, you can devise your own scraping tools. Old screwdrivers with

Use of the optional HG030 deflector nozzle is essential.
On profiled surfaces, paint can be removed using a spatula and brushed off using a soft wire brush (Fig. 5).

SHAPING PLASTIC TUBING
Attach the optional HG040 reflector nozzle. To avoid kinking the tubing, fill the tubing with sand and seal at both ends (Fig. 6).
Heat the tubing evenly by moving it from side to side.
