Overload Clutch
If the drill bit jams or edges, the drive to the
drill spindle is interrupted.
Due to the arising forces always hold the
machine firmly with both hands and
provide for a secure stance.
Drill Bits with Cylindrical
Shanks
With the key or keyless chuck (accessory) and
the associated adapter (accessory), tools with cy-
lindrical shafts can be mounted.
Set the impact stop switch 6 to "Drill-
ing" (only at a standstill).
Clean and lightly grease the adapter shank.
Insert the assembled chuck with a twisting man-
ner into the tool holder until it latches. The chuck
locks itself. Check the locking by pulling on the
chuck.

Screwdriving (GBH 2 SR)
For screwdriving, the universal bit holder with
SDS-plus shank (accessory) must be used.
– Set the direction of rotation to right-hand rota-
tion.
– Regulate the speed with the On/Off switch 4.
Dust extraction
The dust extraction keeps the work area
clean, prevents high dust contamination of
the breathing air and makes the disposal eas-
ier.
The machine can be plugged directly into the re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote control starting. The vacuum cleaner
starts automatically when the machine is
switched on.
Dust Extraction Attachment
Mount the dust extraction attachment (acces-
sory) and connect the vacuum cleaner. The dust
extraction attachment springs back to the prede-
termined drilling depth, which allows for close
seating of the attachment head to the surface.
