Mounting the Dust Extraction Attachment (see figure F)
For dust extraction, the dust extraction attachment (accesso-
ry) is required. When drilling, the dust extraction attachment
retracts so that the attachment head is always close to the
surface at the drill hole.
– Press the button for depth stop adjustment 9 and remove
the depth stop 10. Press button 9 again and insert the dust
extraction attachment into the auxiliary handle 11 from the
front.
– Connect an extraction hose (diameter 19 mm, accessory)
to the extraction sleeve 16 of the dust extraction attach-
ment.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extraction At-
tachment (see figure G)
The required drilling depth X can also be adjusted 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 movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Loosen the wing bolt 20 on the dust extraction attach-
ment.
– Without switching the power tool on, apply it firmly to the
drilling location. The SDS-plus drilling tool must face
against the surface.
– Position the the guide pipe 21 of the dust extraction at-
tachment in its holding fixture in such a manner that the
head of the dust extraction attachment faces against the
surface to be drilled. Do not slide the guide pipe 21 further
over the telescopic pipe 19 of the dust extraction attach-
ment than required, so that as much as possible of the
scale 19 on the telescopic pipe remains visible.
– Retighten the wing bolt 20 again. Loosen the clamping
screw 17 on the depth stop of the dust extraction attach-
ment.
– Move the depth stop 18 on the telescopic pipe 19 in such
a manner that the clearance X shown in the figure corre-
sponds with the required drilling depth.
– Tighten the clamping screw 17 in this position.
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.
Setting the operating mode
With the selector switch for drilling/hammer drilling 8, the op-
erating mode of the machine is selected.
Note: Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
Bosch Power Tools
– To change the operating mode, press the release button 7
and turn the drilling/hammer drilling selector switch 8 to
the desired position until it can be heard to latch.
Position for hammer drilling in concrete or
stone as well as for chiselling (chiselling only
with the MV 200 accessory)
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for screw-
driving and thread cutting
Reversing the rotational direction (GBH 2-22 RE)
The rotational direction switch 4 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 6 actuated.
Right rotation: Turn the selector switch for drilling/
hammer drilling 4 on both sides to the stop in the position
.
Left rotation: Turn the selector switch for drilling/
hammer drilling 4 on both sides to the stop in the position
.
Set the direction of rotation for hammer drilling, drilling and
chiselling always to right rotation.
Switching On and Off
– To start the machine, press the On/Off switch 6.
– To lock the On/Off switch, keep it pressed and additionally
push the lock-on button 5.
– To switch off the machine, release the On/Off switch 6.
When the On/Off switch 6 is locked, press it first and then
release it.
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 6
is pressed.
Light pressure on the On/Off switch 6 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Overload Clutch
If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.
Working Advice
Before any work on the machine itself, pull the mains
plug.
