Push the charged battery into the battery holder until it
clicks into place.
The lithium-ion battery is protected against deep discharge
by "Electronic Cell Protection (ECP)". A protective circuit
switches the heat gun off when the rechargeable battery is
drained.
Follow the instructions on correct disposal.

Removing the Battery

To remove the rechargeable battery, press the battery re-
lease button and pull the battery out. 

Do not use force to do

this.

Battery charge indicator

The green LEDs on the battery charge indicator indicate the
state of charge of the rechargeable battery. For reasons of
safety, you can call up the state of charge only when the heat
gun is off.
Press the button for the battery charge indicator   or 

 to

show the state of charge. This is also possible when the re-
chargeable battery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the rechargeable battery is defective
and must be replaced.

Operation

Starting operation

u

Remove the rechargeable battery before changing ac-
cessories or storing the heat gun.

 This safety measure

prevents the heat gun from being started accidentally.

Creation of Smoke During Initial Use

A coating protects the metal surfaces from corrosion ex-
works. This protective layer evaporates during initial use.
The heat gun may display discolourations on the nozzle 

(1)

due to the production process. These do not count as dam-
age; the functioning of the heat gun is not affected.

Selecting a Power Setting

With the output level setting 

(3)

 you can choose between

two different output levels. The LED worklight flashes briefly
while switching:
– Setting 300 °C

With this setting, you can, for instance, thaw water pipes
or process heat shrink plastic tubes. Upon switching on,
this temperature is reached in less than 6 s. With a fully
charged 8 Ah rechargeable battery, the runtime is up to
21 min.

– Setting 500 °C

With this setting, you can, for instance, remove paint or
soft-solder.

The specifications on heating-up time refer to measurements
at room temperature.

Switching On

To 

switch on

, first press the unlocking switch 

(4)

 and then

the on/off switch 

(5)

. After starting, you can release the un-

locking switch 

(4)

. The unlocking switch 

(4)

 does not have

to be pressed again during operation.
Upon starting the heat gun, the LED worklight 

(6)

 switches

on and illuminates the work area.

Switching Off

To switch off the tool, release the on/off switch 

(5)

.

Switch off the heat gun at the rechargeable battery 

(9)

 to al-

low it to cool down.

Restart Protection

If the rechargeable battery 

(9)

 is removed from the heat gun

while in operation and the on/off switch 

(5)

 is still being held

down when it is reinserted, the restart protection will activ-
ate. The LED worklight 

(6)

 flashes and the heat gun does not

start.
Release the on/off switch 

(5)

 and switch the heat gun back

on as usual.

Overheat Protection for the Rechargeable Battery

If the rechargeable battery 

(9)

 gets too hot during operation,

the output is reduced. The LED worklight 

(6)

 flashes slowly

for as long as the on/off switch 

(5)

 is pressed.

If the heat gun continues to be operated and the temperat-
ure in the rechargeable battery increases further, the heat
gun will switch itself off.

Reduced Output

The heat gun is compatible with all available 18 V Bosch Pro-
fessional rechargeable batteries.
When operating the heat gun with rechargeable batteries
smaller than the recommended 4 Ah, however, the heat gun
will not reach full power at the 500 °C setting (the temperat-
ure is not reached and the air volume is reduced). In order to
