Replacing the Drill Chuck
For power tools without spindle lock, the
drill chuck must be replaced by an author-
ised after-sales service agent for Bosch
power tools.
The drill chuck must be tightened with a
tightening torque of approx. 30–35 Nm.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Reversing the Rotational Direction
(see figures I – J)
The rotational direction switch 8 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right Rotation: For drilling and driving in
screws, push the rotational direction switch 8
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 6 to the "Drill-
ing" symbol.
Impact Drilling
Set the selector switch 6 to the "Im-
pact drilling" symbol.
The selector switch 6 engages noticeably and
can also be actuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 9
and keep it pressed.
Bosch Power Tools
To lock the pressed On/Off switch 9, press the
lock-on button 7.
To switch off the machine, release the On/Off
switch 9 or when it is locked with the lock-on
button 7, briefly press the On/Off switch 9 and
then release it.
Adjusting the Speed/Impact Frequency
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Working Advice
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
Do not operate the power tool stationary. It
is not designed for operation in a drill stand.
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
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.
