Assembly
Battery Charging
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
To remove the battery 6 press the unlocking buttons 7 and
pull out the battery downwards. Do not exert any force.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Changing the Tool (see figure A)
f Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
The drill spindle is locked when the On/Off switch 9 is not
pressed. This makes quick, convenient and easy changing of
the tool in the drill chuck possible.
Open the keyless chuck 1 by turning in rotation direction n,
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 1 by hand in ro-
tation direction o until the locking action (“click”) is no longer
heard. This automatically locks the chuck.
The locking is released again to remove the tool when the col-
lar is turned in the opposite direction.
Dust/Chip Extraction
f Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing 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 country for the
materials to be worked.
f Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the Battery
f Use only original Bosch O-pack batteries with the volt-
age given on the type plate of your machine. The use of
other batteries can lead to injuries and danger of fire.
Set the rotational direction switch 8 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 6 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the Rotational Direction (see figure B)
The rotational direction switch 8 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 9 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 8 left to the stop.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 8 right to the stop.
Setting the Torque
With the torque presetting ring 2 the required torque setting
can be preselected in 22 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 un-
screwing screws.
Setting the Operating Mode (see figure C)
With the operating mode preselection ring 3, you can select
between drilling/screwdriving and impact drilling.
Drilling and screwdriving
Set the preselection ring 3 to the “Drilling without
impact” symbol.
Impact drilling
Set the preselection ring 3 to the “Impact drilling”
symbol.
In the “Impact drilling” position, the safety clutch is deactivat-
ed and the maximum power is always effective.
