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.
2 609 141 014 | (3.5.13)
For unscrewing screws, set the rotational direction switch 5
to left rotation and pull off the screwing-depth stop 4 toward
the front without turning the adjustment sleeve.
Working with the screwing-depth stop 4 is also possible when
adapting the screw-in depth.
Belt Clip
With the belt clip 8, the machine can be hung onto a belt. The
user has both hands free and the machine is always at hand.
Maintenance and Service
Maintenance and Cleaning
 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.
 For safe and proper working, always keep the machine

When the battery is no longer operative, please refer to an au-
thorised after-sales service agent for Bosch power tools.
