Removing the Extraction Device (see figure E)
For disassembly of the extraction device 12, press release
button 20 and pull off the extraction device 12 toward the
front.
Stowing the Extraction Device (see figure F)
For stowing the extraction device 12 in the case, remove the

Attach the locking latch 22 or empty the dust collector 13 be-
fore placing down the extraction device.

Auxiliary Handle

 Operate your machine only with the auxiliary handle
10.
 Before any work, make sure that the wing bolt 11 is
firmly tightened. Loss of control can cause personal inju-
ry.
The auxiliary handle 10 can be set to any position for a secure
and low-fatigue working posture. Turn the wing bolt for adjustment of the auxiliary handle 11 in
anticlockwise direction and set the auxiliary handle 10 to the
required position. Then tighten the wing bolt 11 again in
clockwise direction.
Adjusting the Drilling Depth (see figure G)
The required drilling depth X can be set with the depth stop 1.
Press the button for the depth stop adjustment 5 and insert
the depth stop into the auxiliary handle 10.
The knurled surface of the depth stop 1 must face downward.
Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds with the
desired drilling depth X.
Changing the Tool (see figure H)
Keyless Chuck
Hold the rear sleeve 3 of the keyless chuck 4 tight and turn the
front sleeve 2 in rotation direction , until the tool can be in-
serted. Insert the tool.
Hold the rear sleeve 3 of the keyless chuck 4 tight and firmly
turn the front sleeve 2 in rotation direction  by hand.
Screwdriver Tools
When working with screwdriver bits 24, a universal bit holder
23 should always be used. Use only screwdriver bits that fit
the screw head.
For driving screws, always position the "Drilling/Impact Drill-
ing" selector switch 6 to the "Drilling" symbol.
Replacing the Drill Chuck
 For power tools without spindle lock, the drill chuck
must be replaced by an authorised after-sales service
agent for Bosch power tools.
The drill chuck must be tightened with a tightening
torque of approx. 30–35 Nm.
Bosch Power Tools
Operation

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er 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 reverse the rota-
tional 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 "Drilling" symbol.
Impact Drilling
Set the selector switch 6 to the "Impact drilling"
symbol.
The selector switch 6 engages noticeably and can also be ac-
tuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 9 and keep it
pressed.
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.
To save energy, only switch the power tool on when using it.
Adjusting 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 9
is pressed.
Light pressure on the On/Off switch 9 results in low speed/im-
pact 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 de-
signed for operation in a drill stand.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
