Set the rotational direction switch 10 to the cen-
tre position to protect the power tool against
accidental starting.
Insert the charged battery 8 from the front into
the base of the power tool. Push the battery
completely into the base until the red stripe can
no longer be seen and the battery is securely
locked.
Reversing the Rotational Direction
(see figure D)
The rotational direction switch 10 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 11 actuated.
Right Rotation: For drilling and driving in
screws, push the rotational direction switch 10
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 10 through to the right stop.
Setting the Torque
With the torque presetting ring 2 the required
torque setting can be preselected in
25+1 steps. With the correct setting, the insert
tool is stopped as soon as the screw is screwed
flush into the material or when the adjusted
torque is reached. The safety clutch is deactivat-
ed in the " " position, e. g. for drilling.
Select a higher setting or switch to the
" " symbol when unscrewing screws.
Setting range 1–20:
Lower torque for screwing in screws with small
diameter or into soft materials. Fine torque gra-
dients between the individual setting positions.
Setting range 21–25:
Higher torque for screwing in screws with large
diameters or into hard materials. Coarse torque
gradients between the individual setting posi-
tions.
Setting the Operating Mode
(GSB 14,4 VE-2 LI/GSB 18 VE-2 LI)
(see figure E)
With the operating mode preselection ring 4,
you can select between drilling/screwdriving
and impact drilling.
Bosch Power Tools
Drilling and screwdriving
Set the preselection ring 4 to the "Drill-
ing without impact" symbol.
Impact drilling
Set the preselection ring 4 to the "Im-
pact drilling" symbol.
In the "Impact drilling" position, the safety
clutch is deactivated and the maximum power is
always effective.
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
11 and keep it pressed.
The power light 9 lights up when the On/Off
switch 11 is slightly or completely pressed, and
allows the work area to be illuminated when
lighting conditions are insufficient.
To switch off the machine, release the On/Off
switch 11.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 11 is pressed.
Light pressure on the On/Off switch 11 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 11 is not pressed, the
drill spindle and thus the tool holder are locked.
