To save your own combination:

– Press the memory button(11) to select the memory pre-

set you want.

– Set the desired temperature and airflow. The memory

preset(5) flashes to indicate that the saved combination

has been changed.

– Press and hold down the memory button(11). The

memory preset(5) flashes for approx. 2s. When it lights

up continuously, the new combination has been saved.

Practical advice

uPull the mains plug out of the plug socket before car-

rying out any work on the heat gun.

Note: Do not position the nozzle(1) too close to the work-

piece that you are using the power tool on. The resulting air

blockage can lead to the heat gun overheating.

Removing the heat shield

When working in particularly tight spaces, you can remove

the heat shield(2) by turning it.

uCaution: Nozzle is hot! Working without the heat shield

increases the risk of burns.

To remove or put on the heat shield(2), switch the heat gun

off and let it cool down.

To cool down faster, you can also let the heat gun run briefly

at the lowest temperature that can be set.

Turning off the heat gun

Put down the heat gun on the storage surfaces(3) to let it

cool down, or to keep both hands free to work.

uBe especially careful when working with the turned-

off heat gun! The heat from the nozzle or the air flow can

cause burns.

Position the heat gun on an even, stable surface. Ensure that

it cannot tip over. Secure the cable outside your work area

so that it cannot knock down or pull down the heat gun.

Switch the heat gun off if not used for a sustained period of

time, and disconnect from the mains.

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 de-

pends on the material you are working on (metal, plastic

etc.) and the intended working method.

The optimum temperature for each application can be de-

termined 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 ac-

cessories. 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.

uTake 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.

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)

uThe glass protection nozzle (15) (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(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).
