The battery is supplied partially charged. Completely
charge the battery before using your power tool for
the first time. The lithium ion battery can be charged
at any time without reducing its service life. Interrupt-
ing the charging procedure does not damage the bat-
tery.
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 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.
Observe the notes for disposal.
Changing the Tool (see figure B)
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.
Inserting
Pull the locking sleeve 3 forward, push the insert tool
to the stop into the tool holder 2 and release the lock-
ing sleeve 3 to lock the insert tool.
For quick changing of bits, it is recommended to use
a universal bit holder 10.
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. Using other batteries can lead
to injuries and pose a fire hazard.
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 posi-
tion in order to avoid unintentional starting. Insert the
charged battery 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
rotational 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 depressed.
The power light 4 lights up when the On/Off switch 9
is slightly depressed, and enables illumination of the
screwing location in unfavourable light conditions.
To switch off the machine, release the On/Off switch
9.
Adjusting the Speed
The speed of the switched on power tool can be vari-
ably adjusted, depending on how far the On/Off
switch 9 is pressed.
Light pressure on the On/Off switch 9 results in a low
rotational 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 of 70 °C is exceeded,
the speed is reduced. The power tool will not run at
full capacity until after cooling down.
Protection Against Deep Discharging
The Li-ion battery is protected against deep discharg-
ing 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.
