 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
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.
Removing the battery
The battery 9 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 10 unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery 9, press the unlocking button 10 and
pull out the battery toward the front. Do not exert any force.
Changing the Tool (see figure A)
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Pull off the screwing-depth stop 4 toward the front. Pull out
the screwdriver bit 1. If required, the universal bit holder 13
can also be pulled off and replaced.
After changing the tool, reattach the screwing-depth stop 4.
Operation
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 5 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 9 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the rotational direction
The rotational direction switch 5 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 7 actuated.
1 609 92A 1WK | (14.7.16)
Rotate clockwise: Move the rotational direction switch 5
on both sides up to the stop into position
Rotate anticlockwise: Move the rotational direction
switch 5 on both sides up to the stop into position
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
The LED 12 lights up when the On/Off switch 7 is halfway or
fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To lock the pressed On/Off switch 7, press the lock-on button
6.
To switch off the machine, release the On/Off switch 7 or
when it is locked with the lock-on button 6, briefly press the
On/Off switch 7 and then release it.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 7 is pressed.
Light pressure on the On/Off switch 7 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Adjusting the Screw-in Depth (see figure B)
With the adjustment sleeve 3, the screw-in depth of the screw
head into the workpiece can be preset in 8 locking steps per
full turn. Each step corresponds with a 0.25 mm change of
the screw-in depth.
Turning the adjustment sleeve 3 in clockwise direction results
in a greater screw-in depth; turning in anticlockwise direction
reduces the screw-in depth.
The required setting is best determined by testing.
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 only when it is
switched off. Rotating tool inserts can slip off.
Guide the screw toward the screwdriving bit 1. The screw is
held in place by the magnet pull of the universal bit holder 13.
Firmly push the tip of the screw into the material to be
screwed until the screwing-depth stop 4 faces against the
workpiece.
Switch the machine on. The screw is screwed into the materi-
al until the adjusted screw-in depth is reached. The drive is
disengaged and the tool holder no longer rotates. Check the
screw-in depth and readjust, if required.
