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 charging/discharging cycles.
To remove the battery 10 press the unlocking buttons
9 and pull out the battery downwards. Do not exert
any force.
The battery is equipped with a NTC temperature con-
trol which allows charging only within a temperature
range of between 0 °C and 45 °C. A long battery serv-
ice life is achieved in this manner.
A significantly reduced working period after charging
indicates 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 (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational
direction switch to the centre position. Unin-
tentional actuation of the On/Off switch can lead to
injuries.
Hold the rear sleeve 3 of the keyless chuck 1 and turn
the front sleeve 2 in anticlockwise direction until until
the tool can be inserted. Insert the tool.
Hold the rear sleeve 3 of the keyless chuck 1 and firmly
turn the front sleeve 2 in clockwise direction until a
“click” can be heard. This automatically locks the drill
chuck.
The locking is released again to remove the tool when
the front sleeve 2 is turned in the opposite direction.
Operation
Starting Operation
Inserting the Battery
f Use only original Bosch O-pack batteries with
the voltage 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 12 to the centre
position in order to avoid unintentional starting. Insert
the charged battery 10 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 12 is used to reverse the
rotational direction of the machine. However, this is not
possible with the On/Off switch 13 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 12 left to the stop.
The indicator for right rotation 5 lights up when
the On/Off switch 13 is actuated.
Left Rotation: For loosening or unscrewing screws,
push the rotational direction switch 12 right to the stop.
The indicator for left rotation 6 lights up when
the On/Off switch 13 is actuated.
Setting the Torque
The required torque can be preselected in 10 steps
with the torque preselection ring 4. With the correct
setting, the insert tool is stopped as soon as the screw
is screwed flush into the material or when the set
torque is reached.
Select a higher setting when driving out screws, or set
to the symbol “Drilling”.
Drilling
The safety clutch is deactivated in the “Drilling” posi-
tion.
Switching On and Off
To start the machine, press the On/Off switch 13 and
keep it depressed.
The power light 11 lights up when the On/Off switch
13 is halfway or fully depressed, and enables illumina-
tion of the screwing location in unfavourable light con-
ditions.
To switch off the machine, release the On/Off
switch 13.
