Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batteries
with the voltage listed on the nameplate of
your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Set the rotational direction switch 10 to the cen-
tre position to protect the power tool against ac-
cidental starting.
Insert the charged battery 8 from the front into
the base of the power tool. Push the battery com-
pletely into the base until the red stripe can no
longer be seen and the battery is securely locked.
Reversing the Rotational Direction
(see figure F)
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.
2 609 932 625 | (20.10.08)
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 in-
to the material or when the adjusted torque is
reached. The safety clutch is deactivated 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 G)
With the operating mode preselection ring 4, you
can select between drilling/screwdriving and im-
pact drilling.
Drilling and screwdriving
Set the preselection ring 4 to the "Drilling
without impact" symbol.
Impact drilling
Set the preselection ring 4 to the "Impact
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 stand-
still or when the machine is running. Howev-
er, this should not be done while operating
at full load or maximum speed.
Two speed ranges can be preselected with the
gear selector 3.
