Assembly
Battery Charging
Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion battery of your power tool.
Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Do not continue to press the On/Off
WARNING
switch after the machine has been au-
tomatically switched off. The battery can be damaged.
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.
Observe the notes for disposal.
Removing the Battery
The battery 4 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 5 unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery 4, press the unlocking button 5 and
pull out the battery toward the front. Do not exert any force.
Changing the Tool (see figure A)
Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
Inserting
Pull the locking sleeve 2 forward, push the insert tool to the
stop into the tool holder 1 and release the locking sleeve 2 to
lock the insert tool.
Use only screwdriver bits with ball catch 9 (DIN 3126-E6.3).
Other screwdriver bits 11 can be used with a universal bit
holder with ball catch 10.

Removing
Pull the locking sleeve 2 forward and remove the insert tool.
Operation
Method of Operation
The tool holder 1 with the tool is driven by an electric motor
via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in action).
The impact mechanism is activated as soon as the screwed
connection runs tight and thus load is put on the motor. In this
instance, the impact mechanism converts the power of the
motor to steady rotary impacts. When loosening screws or
nuts, the process is reversed.
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.
Set the rotational direction switch 6 to the centre position to
protect the power tool against accidental starting.
Insert the charged battery 4 from the front into the base of the
power tool until the battery is securely locked.
Reversing the Rotational Direction (see figure B)
The rotational direction switch 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 7 actuated.
Right rotation: For driving in screws and tightening nuts,
press the rotational direction switch 6 through to the left
stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 6 through to the
right stop.
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
To switch off the machine, release the On/Off switch 7.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 7 is pressed.
Light pressure on the On/Off switch 7 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature range of 0–70 °C is exceeded, the speed is re-
duced. The power tool will not run at full speed until reaching
the allowable battery temperature.
