Setting the Air Flow and Temperature
(PHG 500-2/PHG 600-3)
With the On/Off switch 4, you can select be-
tween different air flows and temperature com-
binations:
Setting PHG 500-2
l/min °C
I 240 300
II 450 500
III –
PHG 600-3: The cold air setting I is suitable for
cooling a warmed workpiece or for drying of
paint. It is also suitable for cooling the power
tool before placing it down or when changing
nozzles.
Regulating the Air flow (PHG 630 DCE)
With the On/Off switch 5, you can regulate the
air flow in three steps:
Setting
I
II
III
As an example, reduce the air flow when the sur-
rounding area of a workpiece is not to be heated
excessively or when a light workpiece could be
moved away by the air flow.
In the cold air setting I, the temperature is fixed
at 50 °C; in the hot air settings II and III, the
temperature can be continuously regulated.
Setting the Temperature (PHG 630 DCE)
The temperature can only be regulated in the
hot air settings II and III. In the cold air setting
I, the temperature is fixed at 50°C.
When switching from the cold air setting I to one
of the hot air settings, the last set target temper-
ature is indicated for approx. 3 seconds be-
tween flashing arrows on display 7. The target
temperature is the same for both hot air steps II
and III, and does not change when switching be-
tween the two steps.
To increase the temperature, press on the "+" of
the temperature-control button 6, to decrease
the temperature, press on the "–".
Bosch Power Tools
Briefly pressing the temperature-control button
6 at the respective position increases or de-
creases the temperature by 10 °C. Prolonged
pressing of the temperature-control button con-
tinuously increases or decreases the tempera-
ture by 10 °C, until the button is released or the
PHG 600-3
maximum or minimal temperature is reached.
l/min °C
After a change to the temperature setting, the
power tool requires a short period to warm up
250 50
or cool down the air flow. During this period, the
350 400
target temperature is indicated between the
flashing arrows in the display 7. When the target
– 500 600
temperature is reached, the arrows go out and
the display indicates the actual temperature.
When switching from the hot air steps II or III to
the cold air setting I, a short time is required un-
til the power tool has cooled to 50 °C. During
the cooling period, the actual temperature at
the nozzle outlet is indicated on the display 7.
The cold air setting I is suitable for cooling a
warmed workpiece or for drying of paint. It is al-
so suitable for cooling the power tool before
l/min
placing it down or when changing nozzles.

Note: Do not apply the nozzle 1 too close to the
workpiece being worked. The hot air build-up
can lead to overheating of the power tool.
Removing the Heat Protection
The heat protection collar 2 can be removed
when working at particularly hard-to-reach
locations.
To remove or mount the heat protection collar 2,
switch the power tool off and allow it to cool
down.
To speed up the cooling, the power tool can also
be operated for a short period with the lowest
adjustable temperature.
Turn the heat protection collar 2 in anticlock-
wise direction to remove and in clockwise direc-
tion to mount again.
Before any work on the machine itself, pull
the mains plug.
Be careful of the hot nozzle! Increased dan-
ger of burning exists when working without
the heat protection collar.
