and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
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.
Battery Charging
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
the maximum performance of the battery, use the charger to
fully charge the battery before first use.
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 pro-
tective circuit: The application tool stops moving.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery
The battery (9) is equipped with two locking levels to pre-
vent the battery from falling out when pushing the battery re-
lease button (10)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 (9), press the release button (10)
and pull the battery forward and out of the power tool. Do
not use force to do this.
Changing the Tool (see figure A)
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.
Pull the depth stop (4) off towards you. Pull the screwdriver
bit (1) out. If required, the universal bit holder (13) can also
be pulled out and replaced.
After changing the tool, reattach the depth stop (4).
Operation
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.
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (5) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (9) into the handle until you feel it engage and it is
flush with the handle.
Setting the Rotational Direction
The rotational direction switch (5) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (7) is being pressed.
Right rotation: Slide the rotational direction switch
(5) all the way into position
Left rotation: Slide the rotational direction switch (5)
all the way into position
Switching on/off
To start the power tool, press and hold the on/off switch
(7).
The LED lights up when the on/off switch (7) is lightly or fully
pressed, meaning that the work area is illuminated in poor
lighting conditions.
Press the lock-on button (6) to lock the on/off switch (7) in
this position.
To switch off the power tool, release the on/off switch (7);
or, if the switch is locked with the lock-on button (6), briefly
press the on/off switch (7) and then release it.
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (7) to varying extents.
