4) Power tool use and care
5) Service
a) Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was de-
signed.
a) Have your power tool serviced by a quali-
fied repair person using only identical re-
placement parts. This will ensure that the
safety of the power tool is maintained.
b) Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch
is dangerous and must be repaired.
Machine-specific
Safety Warnings
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools. Such preventive safety meas-
ures reduce the risk of starting the power
tool accidentally.
f Wear hearing protection. Exposure to noise
can cause hearing loss.
f Always use the auxiliary handle supplied
with the machine. Loss of control can cause
personal injury.
f Use suitable detectors to determine if utility
lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric
shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property
damage or may cause an electric shock.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these in-
structions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
f When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age of parts and any other condition that
may affect the power tool’s operation. If
damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
f Do not work materials containing asbestos.
f) Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
Asbestos is considered carcinogenic.
f Take protective measures when dust can de-
velop during working that is harmful to one’s
health, combustible or explosive. Example:
Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip ex-
traction when connectable.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instruc-
tions, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations differ-
ent from those intended could result in a
hazardous situation.
f Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.

that are inserted in the SDS-plus drill chuck.
23.07.2007, Robert Bosch GmbH, Power Tools Division
D-70745 Leinfelden-Echterdingen
For drilling without impact in wood, metal,
ceramic and plastic as well as for screwdriving,
tools without SDS-plus are used (e. g., drills with
cylindrical shank). For these tools, a keyless
chuck or a key type drill chuck are required.

Inserting Drilling Tools without SDS-plus
Note: Do not use tools without SDS-plus for ham-
mer drilling! Tools without SDS-plus and their
drill chucks are damaged by hammer drilling.
Clean the shank end of the adapter shank and
apply a light coat of grease.
Insert the key type drill chuck with the adapter
shank into the tool holder with a turning motion
until it automatically locks.

of the key type drill chuck 13 and clamp the tool
uniformly.
Removing the Key Type Drill Chuck
Push the locking sleeve 3 toward the rear and
pull out the key type drill chuck 13.
Set the selector switch 7 to the “Drilling” sym-
bol.
Removing Drilling Tools without SDS-plus
Changing the Tool
Turn the sleeve of the key type drill chuck 13 with
the drill chuck key in anticlockwise direction until
the drilling tool can be removed.
The dust protection cap 2 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 2 is not damaged.
Dust Extraction with the Dust Extraction
Attachment (Accessory)
f A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Mounting the Dust Extraction Attachment
(see figure G)
Inserting SDS-plus Drilling Tools (see figure E)
For dust extraction, the dust extraction attach-
ment (accessory) is required. When drilling, the
dust extraction attachment retracts so that the
attachment head is always close to the surface at
the drill hole.
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
Clean and lightly grease the shank end of the tool.
Press the button for depth stop adjustment 8
and remove the depth stop 11. Press button 8
again and insert the dust extraction attachment
into the auxiliary handle 10 from the front.
Insert the tool in a twisting manner into the tool
holder until it latches itself.
Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no effect
on the accuracy of the drill hole, as the drill bit
centres itself upon drilling.
Connect an extraction hose (diameter 19 mm,
accessory) to the extraction sleeve 15 of the dust
extraction attachment.
The vacuum cleaner must be suitable for the
material being worked.
Removing SDS-plus Drilling Tools (see figure F)
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Push back the locking sleeve 3 and remove the
tool.

Adjusting the Drilling Depth on the Dust
Extraction Attachment (see figure H)
Setting the Operating Mode
With the selector switch for drilling/hammer
drilling 7, the operating mode of the machine is
selected.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine
can be damaged.
To change the operating mode, turn the selector
switch for “drilling/hammer drilling” 7 to the
requested position.
The required drilling depth X can also be adjust-
ed when the dust extraction attachment is
mounted.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder 1. Otherwise, the mova-
bility of the SDS-plus drilling tool can lead to in-
correct adjustment of the drilling depth.
Loosen the wing bolt 19 on the dust extraction
attachment.
Position for hammer drilling in
concrete or stone
Without switching the power tool on, apply it
firmly to the drilling location. The SDS-plus drill-
ing tool must face against the surface.
Position the the guide pipe 20 of the dust extrac-
tion attachment in its holding fixture in such a
manner that the head of the dust extraction at-
tachment faces against the surface to be drilled.
Do not slide the guide pipe 20 further over the tel-
escopic pipe 18 of the dust extraction attachment
than required, so that as much as possible of the
scale 18 on the telescopic pipe remains visible.
Position for drilling without impact
in wood, metal, ceramic and plastic
as well as for screwdriving
Reversing the Rotational Direction
(GBH 2-18 RE) (see figure I)
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 5 actuated.
Retighten the wing bolt 19 again. Loosen the
clamping screw 16 on the depth stop of the dust
extraction attachment.
Right rotation: Push the rotational direction
switch 6 rightward to the stop.
Left rotation: Push the rotational direction
switch 6 leftward to the stop.
Move the depth stop 17 on the telescopic pipe 18
in such a manner that the clearance X shown in
the figure corresponds with the required drilling
depth.
For hammer drilling and drilling, always set the
direction of rotation to right rotation.
Tighten the clamping screw 16 in this position.
Switching On and Off
To start the machine, press the On/Off switch 5.
Operation
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button 4.
To switch off the machine, release the On/Off
switch 5. When the On/Off switch 5 is locked,
press it first and then release it.
Starting Operation
f 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.
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 5 is pressed.
Light pressure on the On/Off switch 5 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
