Switching On and Off
To start the machine, press the On/Off switch 7
and keep it depressed.
To switch off the machine, release the On/Off
switch 7.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 7 is pressed.
Light pressure on the On/Off switch 7 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Run-on Brake
When the On/Off switch 7 is released, the chuck
brakes to a stop, thus preventing the run-on of
the tool.
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 var-
iably adjusted. Each turn corresponds with a
0.2 mm change of the screw-in-depth.
Turning the adjustment sleeve 3 in clockwise di-
rection results in a greater screw-in depth; turn-
ing in anticlockwise direction reduces the screw-
in depth.
Push the adjustment sleeve 3 toward the front to
the stop, adjust the screw-in-depth by turning
the adjustment sleeve 3 and then pull the adjust-
ment sleeve 3 back again until it latches.
The required setting is best determined by test-
ing.

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 integrated mag-
net ring in the tool holder. Firmly push the tip of
the screw into the material to be screwed until
the screwing-depth stop 4 faces against the
workpiece.
Bosch Power Tools
Switch the machine on. The screw is screwed in-
to the material 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.
For unscrewing screws, set the rotational direc-
tion switch 8 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.
Light (accessory)
With the light bulb 9, the screwing location can
be illuminated when lighting conditions are inad-
equate.
Remove the end cap 10 and insert the light bulb
9 into the opening to the stop.
To switch the light bulb 9 on or off, turn the
switch in the required direction.
Note: When using the machine without the light
bulb 9, the end cap 10 must always be inserted
into the housing.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
For safe and proper working, always keep
the machine and ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article number
given on the type plate of the machine.
