– After reaching the desired drilling depth, pull the drill bit
out of the drill hole first and then switch off the impact drill.
– Use the extraction device only with the filter element 17
mounted, as otherwise dust/chips could access the interi-
or of the power tool and cause damage.
– Check the condition of the filter element 17 regularly. Re-
place a damaged filter element immediately.
– The dust protection ring 19 can wear, especially when
working with large drill-bit diameters. Replace the dust
protection ring when worn/damaged.
Mounting the Extraction Device (see figure A)
Guide the extraction device 12 from the front toward the bot-
tom side of the impact drill. Pay attention that the extraction
device 12 faces flush against the casing and that it is locked.
Cleaning the Extraction Device (see figures B–D)
The dust collector 13 is sufficient for approx. 10 drillings with
a drilling diameter of 10 mm.
When the extraction force diminishes or when the level indi-
cator 14 is full, the dust collector 13 must be emptied. For
this, press on the riffled surface of the release button 16 and
take off the dust collector 13.
Empty and clean the dust collector 13. Clean the filter ele-
ment 17 by gently striking or tapping against it.
Check the filter element 17 for damage and replace it as re-
quired.
Press on the holder of the filter element 17 and pull it out. Re-
place the filter element 17 including the holder. When placing
on the holder again, make sure that the rubber gasket 18 is in-
serted.
Reattach the dust collector 13 again and lock it by pressing
against the smooth surface of the release button 16.
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
extraction device 12, slide it together and attach clamp 21.
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 correspond 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
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
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.
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.
