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 switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
To remove the battery 7 press the unlocking buttons 6 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.
Observe the notes for disposal.
Changing the Tool (see figure B)
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 3 forward, push the insert tool to the
stop into the tool holder 2 and release the locking sleeve 3 to
lock the insert tool.
Use only screwdriver bits with ball catch 1 (DIN 3126-E6.3).
Other screwdriver bits 13 can be used with a universal bit
holder with ball catch 12.
Removing
Pull the locking sleeve 3 forward and remove the insert tool.
Operation
Method of Operation
The tool holder 2 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.
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Set the rotational direction switch 8 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 7 into the handle so that it can be felt to engage and faces
flush against the handle.

Reversing the rotational direction (see figure C)
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 driving in screws and tightening nuts,
press the rotational direction switch 8 through to the left
stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 8 through to the
right stop.
Switching On and Off
To start the machine, press the On/Off switch 9 and keep it
pressed.
The power light 4 lights up when the On/Off switch 9 is slightly
or completely pressed, and allows the work area to be illumi-
nated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 9.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Battery Charge-control Indication
The battery charge-control indicator 10 consists of three
green LEDs, and indicates the charge condition of the battery
for a few seconds when the On/Off switch 9 is pressed half-
way or fully.

Continuous lighting 2 x green

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.
Protection Against Deep Discharging
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.
Working Advice
Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
The torque depends on the impact duration. The maximum
achieved torque results from the sum of all individual torques
achieved through impact. The maximum torque is achieved
after an impact duration of 6–10 seconds. After this dura-
tion, the tightening torque is increased only minimally.
