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.

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

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.

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.
