Switching on/off
The screwdrivers have a torque-dependent
shut-off clutch that can be set to a value in the
specified range. It activates when the set
torque is reached.
Note: If you are operating the screwdriver with a voltage ad-
apter, you will need to put the constant voltage regulator into
operation first.
To switch on the power tool, press the on/off switch (6)
down fully.
The power tool will switch off automatically when the set
torque is reached.
If the on/off switch (6) is released too early, the pre-
u
set torque will not be reached.

Practical advice

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.
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
Setting the torque (see figures H – I)
The torque depends on the spring preload of the shut-off
clutch. The shut-off clutch is triggered upon reaching the set
torque, both in clockwise and anti-clockwise rotation.
Only use the supplied adjustment tool (21) to set the indi-
vidual torque.
– Slide back the slider (10) on the power tool fully.
– Place the application tool (21) into the tool holder (8)
and turn it slowly.
– Once a small protrusion (setting disc (22)) in the clutch
can be seen through the opening of the housing, insert
the adjustment tool (21) into this protrusion and turn it.
Turning clockwise will result in a higher torque; turning anti-
clockwise will result in a lower torque.
– Remove the adjustment tool (21). Slide the slider (10) to
the front again to protect the clutch from contamination.
Note: The required setting is dependent on the type of
threaded connector and can be best determined by practical
trials. Check a trial screw application with a torque spanner.
If you set the torque to a value outside the specified
u
power range, the shut-off clutch will not be triggered.
Marking the torque setting
To label individually set torques, you can replace the mark-
ing ring (7) with a marking ring of a different colour.
If you use certain EXACT power tools with a torque of 4.5
Nm, for example, you can fit red marking rings on these to
identify the set torque. If you use other EXACT power tools in
a different assembly area with a torque set to 7.5 Nm, you
can fit a marking ring of a different colour (black, blue, green
or yellow) to identify the torque in this area. The different
marking ring colours are only intended as an aid for fitters to
facilitate identifying the set torque on a specific power tool.
Bosch Power Tools
Press the marking ring (7) with a thin screwdriver blade, a
spatula or similar implement.
Always use the power tool with a marking ring to be certain
that the housing is protected against dust and dirt.
LED indicator
Battery charge indicator
If the battery (5) needs to be charged, the LED
indicator (2) flashes green and a sound is emit-
ted. You can only drive in six to eight more
screws.
If the LED indicator lights up red, there is not enough capa-
city left to drive in another screw or the power tool has over-
loaded. The power tool can no longer be switched on. The
lock-off function remains active until the drained battery has
been removed from the power tool and a charged battery in-
serted.
If you are working with a voltage adapter, the red LED (2) in-
dicates overloading.
A significantly reduced operating time of the power tool after
charging indicates that the battery must be replaced soon.
Dispose of depleted batteries in accordance with legal/coun-
try-specific provisions.
Indicator for screwdriving applications
The shut-off clutch is triggered upon reaching
the preset torque. The LED indicator (1) lights
up green.
If the preset torque has not been reached, the LED indicator
(1) lights up red and the tool emits a sound. The screw must
be driven in again.
Repeat protection
If the shut-off clutch is triggered while driving a screw, the
motor will switch off. You will need to wait 0.7 seconds be-
fore you can switch the tool on again. This prevents you from
accidentally retightening screws that are already firmly in
place.

Maintenance and Service

Maintenance and Cleaning

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.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Lubricating the power tool
Lubricant:
Special gearbox grease (225 ml)
Article number 3 605 430 009
Molykote grease
Motor oil SAE 10/SAE 20
– Clean the gearbox with a mild solvent after the first 150
operating hours. Follow the solvent manufacturer's in-
structions on use and disposal. Then lubricate the gear-
