Fasten the drill stand with anchor or quick-
clamping column. Then fold in the drill-hole cen-
tre indicator 10.
Fastening with Anchor (see figure C)
For fastening of the drill stand to brickwork or
concrete with anchor (accessory), drill a sepa-
rate anchor hole.
Clearance from anchor hole–centre of the in-
tended bore hole
optimal
GDB 2500 WE 330 mm
GDB 1600 WE/DE 270 mm
For offset bore drilling, increase the distance
between the anchor hole and the centre of the
intended bore hole by the value m (see "Posi-
tioning the Drill Stand before Fastening").
The following dimensions apply for the anchor
hole:
Diameter
Brickwork 20 mm
Concrete 15 mm
Insert a concrete hammer-drive anchor or a
brickwork anchor 23. Screw the quick-clamping
spindle 24 into the anchor.
Position the drill stand, attach a washer, and
then screw together with the wing nut 25. After
levelling (see "Levelling"), tighten the wing nut
using an open-end spanner, size 27 mm.
Fastening with a Quick-clamping Column
(see figure D and E)
With use of a Bosch quick-clamping column (ac-
cessory), the drill stand can be fastened be-
tween ceiling and floor or between two walls.
The clamping range is between 1.7 m and 3 m.
Position one end of the quick-clamping column
onto the base plate of the drill stand. The
mounting surface for the other end of the quick-
clamping column against the wall must have suf-
ficient stability and be secure against slipping.
For fastening the quick-clamping column, read
and observe its operating instructions.
