not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Charging the battery
Use only the chargers listed on the accessories page.
u
Only these chargers are matched to the lithium-ion bat-
tery of your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
To remove the battery (7), press the release button (8) and
pull the battery downwards out of the power tool. Do not
use force to do this.
The battery features NTC temperature monitoring, which
only permits charging in a temperature range between 0 °C
and 45 °C. This achieves a long battery life.
Removing the battery
The battery (7) is equipped with two locking levels to pre-
vent the battery from falling out when pushing the battery re-
lease button (8)unintentionally. As long as the battery is in-
serted in the power tool, it is held in position by means of a
spring.
Bosch Power Tools
To remove the battery (7), press the release button (8) and
pull the battery forward and out of the power tool. Do not
use force to do this.
Changing the tool (see figure A)
Inserting
Pull the locking sleeve (2) forward, guide the application tool
(1) into the tool holder up to the stop and release the locking
sleeve (2) to lock the application tool.
Use only screwdriver bits with ball catch (12) (DIN 3126-
E6.3). Other screwdriver bits (14) can be inserted using a
universal bit holder with ball catch (13).
Removing
Pull the locking sleeve (2) forward and remove the applica-
tion tool.
Operation
Method of Operation
The tool holder (1) (with the application tool) is driven by an
electric motor via a gear and impact mechanism. The work-
ing 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
u
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Push the charged battery (7) into the base of the power tool
from the front until the battery is securely locked.
Set the rotational direction (see figure B)
The rotational direction switch (9) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drive in screws and tighten nuts, press
the rotational direction switch (9) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (9) through to the right
stop.
Setting the operating mode (see figure C)
Note: Only change the operating mode when the power tool
is switched off. Otherwise, the power tool may become dam-
aged.
To change the operating mode, push the "Drilling/screwdriv-
ing" selector switch (4) to the required position.
If the "Drilling/screwdriving" selector switch (4) cannot be
pushed as far as the stop, gently press the on/off switch
