Working Advice - Bosch GSR Professional 14.4 V-Li Notice Originale

Setting the Torque
The required torque can be preselected in 20
steps with the torque preselection ring 2. With
the correct setting, the insert tool is stopped as
soon as the screw is screwed flush into the ma-
terial or when the set torque is reached.
Select a higher setting when driving out screws,
or set to the symbol "Drilling".
Gear Selection, Mechanical
The gear selector 3 can be actuated at
standstill or when the machine is running.
However, this should not be done while op-
erating at full load or maximum speed.
Two speed ranges can be preselected with the
gear selector 3.
Gear I:
Low speed range; for screwdriving or working
with large drilling diameter.
Gear II:
High speed range; for working with small drilling
diameter.
If the gear selector 3 cannot be pushed through
to the stop, lightly turn the drill chuck with drill.
Switching On and Off
To start the machine, press the On/Off switch 8
and keep it pressed.
To switch off the machine, release the On/Off
switch 8.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 8 is not pressed, the
drill spindle and thus the tool holder are locked.
This enables screws to be screwed in, even
when the battery is empty and allows for the
machine to be used as a screwdriver.

Run-on Brake
When the On/Off switch 8 is released, the chuck
brakes to a stop, thus preventing the run-on of
the tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then re-
lease the On/Off switch 8. By doing so, the head
of the screw does not penetrate into the materi-
al.
Temperature Dependent Overload Protection
When using as intended for, the power tool can-
not be subject to overload. When the load is too
high or the allowable battery temperature of
65 °C is exceeded, the electronic control
switches off the power tool until the tempera-
ture is in the optimum temperature range again.

Working Advice

Apply the power tool to the screw only
when it is switched off. Rotating tool inserts
can slip off.
When the power tool is electrostatically
charged, the built-in electronic control switches
it off. To restart the power tool, press the
On/Off switch 8 again.
Tips
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS=high-speed steel). The
appropriate quality is guaranteed by the Bosch
accessories program.
Before screwing larger, longer screws into hard
materials, it is advisable to predrill a pilot hole
with the core diameter of the thread to approx.
2
/ of the screw length.
