Safety instructions

Read all the safety information and instructions. Failure to observe the safety information and follow instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

• This heat gun is not intended for use by children or persons with physical, sensory, or mental limitations or a lack of experience or knowledge. This heat gun can be used by children aged 8 or older and by persons who have physical, sensory, or mental limitations or a lack of experience or knowledge if a person responsible for their safety supervises them or has instructed them in the safe operation of the heat gun and they understand the associated dangers.
  Otherwise, there is a risk of operating errors and injury.
• Supervise children during use, cleaning, and maintenance. This will ensure that children do not play with the heat gun.
• Handle the power tool with care.
  The power tool produces intense heat which increases the risk of fire and explosion.
• Take particular care when working in the vicinity of flammable materials. The hot airflow or hot nozzle may ignite dust or gases.
• Do not work with the power tool in potentially explosive areas.
• Do not aim the hot airflow at the same area for prolonged periods. Working with plastic, paint, varnish or similar materials may produce easily flammable gases.
• Please be aware that heat is directed to covered flammable materials, which may ignite.
• Safely place the power tool on the storage surfaces after use and let it cool completely before packing it away. The hot nozzle can cause damage.
• Do not leave the switched-on power tool unattended.
• Store idle power tools out of the reach of children. Do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not misuse the cable, for example by using it to carry, hang up or unplug the power tool. Keep the cable away from heat and oil. Damaged or entangled cords increase the risk of electric shock.
• Always wear safety goggles. Safety goggles reduce the risk of injury.
• Pull the plug out of the socket before adjusting the tool settings, changing accessories, or storing the power tool. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Always check the power tool, cable, and plug before use. Stop using the power tool if you discover any damage. Do not open the power tool yourself, and have it repaired only by a qualified specialist using only original replacement parts. Damaged power tools, cables, and plugs increase the risk of electric shock.
  Keep your work area well-ventilated. The gas and steam produced during work are often harmful to one’s health.
• Wear protective gloves and do not touch the nozzle while it is hot. There is a risk of burns.
• Do not direct the airflow at persons or animals.
• Do not use the power tool as a hairdryer. The outgoing airflow is considerably hotter than that of a hair dryer.
• Do not allow foreign objects to enter the power tool.
• The distance between the nozzle and the workpiece depends on the material you are working on (metal, plastic, etc.) and the intended working method. Always test the amount of air and temperature first.
• If operating the power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.
• Never use the power tool if the cable is damaged. Do not touch the damaged cable and pull out the main plug if the cable is damaged while working. Damaged cables increase the risk of an electric shock.
  Products sold in GB only:
  Your product is fitted with a BS 1363/A approved electric plug with an internal fuse (ASTA approved to BS 1362).

If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorized customer service agent. The replacement plug should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into the main socket elsewhere.

Technical Data

A) At an ambient temperature of approx. 20 °C
The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.

Noise/vibration information
Typically, the A-weighted sound pressure level of the power tool is less than 70 dB(A).
Total vibration values ah (triax vector sum) and uncertainty K: ah<2.5 m/s 2, K=1.5 m/s2.

Operation

Starting operation

• Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the power tool.

Creation of Smoke During Initial Use
A coating protects the metal surfaces from corrosion ex-works. This protective layer evaporates during initial use.
Switching On
Slide the on/off switch (2) upwards.
Thermal protection shutdown: If the power tool overheats (e.g. due to a build-up of air or too little air supply), the heating system will automatically switch off, though the blower will continue to run. Once the power tool has cooled back down to its operating temperature, the heating system will automatically switch on again.

Switching Off
Slide the on/off switch (2) downwards into the 0 positions.

• After working at high temperatures for a prolonged period, let the power tool cool down before switching it off. To do this, allow it to run on the lowest temperature setting for a short while.

Selecting a Power Setting
You can choose between different power settings using the on/off switch (2):

Then I power setting is suitable for cooling down a heated workpiece or for drying paint. It is also suitable for cooling down the power tool before putting it down or changing the attachment nozzles.

Practical advice

• Pull the plug out of the socket before carrying out any work on the power tool.

Note: Do not position the nozzle (3) too close to the workpiece that you are using the power tool on. The resulting build-up of air can cause the power tool to overheat.

Setting down the power tool
Set the power tool down on the storage surfaces (1) to leave it to cool down or to keep both hands free to work with.

• Take particular care when working in the vicinity of the power tool while it has been set aside. The heat from the nozzle or the airflow can cause burns.

Position the power tool on an even, stable surface. Ensure that it cannot tip over. Secure the cable outside of your working area so that it cannot pull the power tool down or cause it to flip over.
Switch the power tool off when not in use for a long period and pull the main plug out of the socket.

Example applications (see figures A–B)
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.
The nozzles, which are available as accessories, are compatible with all models of Bosch heat guns.

• Take care when changing the nozzle. Do not touch the nozzle while it is hot. Leave the power tool to cool down before changing the nozzle, and wear protective gloves when doing so. The heat from the nozzle can cause burns.
  To make the power tool cool down quicker, you can also let it run briefly on its lowest temperature setting.

Stripping paint from window frames (see figure A)

• The glass protection nozzle (5) (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 suitable spatula and brush it off with a soft wire brush.

Soft Soldering (see figure B)
Fit the reducing nozzle (6) (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 workpiece. If necessary, remove the flux after the solder joint has cooled down.
