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)
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
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 1 by hand in ro-
tation direction 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
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
2 609 140 727 | (11.4.12)
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.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the Battery
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 "
drilling.
Select a higher setting or switch to the "
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.
