Operation

Starting Operation

Inserting the Battery (see figure D)
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
Set the rotational direction switch 6 to the centre
position in order to avoid unintentional starting.
Insert the charged battery 8 into the handle so
that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure E)
The rotational direction switch 6 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 7 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 6 left to the
stop.
The rotation direction indicator 5 lights up
green.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 6 through to the right stop.
The rotation direction indicator 5 lights up
red.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 4 to the "Drill-
ing" symbol.
Impact Drilling
Set the selector switch 4 to the "Impact
drilling" symbol.
The selector switch 4 engages noticeably and
can also be actuated with the machine running.
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.
Bosch Power Tools
Setting the Speed/Impact Rate
The speed/impact rate 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
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Operating Instructions
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
Tips
The required speed depends on the material to be
worked and the diameter of the tool. Determine
the optimum setting through practical testing.
After longer periods of working at low speed, allow
the machine to cool down by running it for approx.
3 minutes at maximum speed with no load.
For drilling in tiles, set the selector switch 4 to
the "Drilling" symbol. Do not switch over to the
symbol "Impact Drilling" or work with impact un-
til after drilling through the tile.
Use carbide tipped drill bits when working in
concrete, masonry and brick wall.

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.
