Fastening the Drill Stand
Note: Fasten the drill stand free from play to prevent
jamming of the core bit and the tearing out of seg-
ments.
Depending on the type and nature of the structural
material, fasten the drill stand where the bore hole is
intended using an anchor, with vacuum or with the
quick-clamping column.

Fold out the drill-hole centre indicator 12. When work-
ing with the GDB 2500 WE, bring the tip of the drill-
hole centre indicator into alignment with the marked
centre of the intended bore hole. When working with
the GDB 1600 WE/DE, the inner edge of the drill-hole
centre indicator 12 is the reference point.
For offset drilling, move the drill stand away from the
bore hole centre by the value m:

Insert a concrete hammer-drive anchor or a brickwork
anchor 24. Screw the quick-clamping spindle 25 into
the anchor.
Position the drill stand, attach a washer, and then
screw together with the wing nut 26. After levelling (see
"Levelling"), tighten the wing nut using an open-end
spanner, size 27 mm.
Fastening with Vacuum
For fastening the drill stand with vacuum, a Bosch vac-
uum set and a Bosch vacuum pump (both accessories)
are required.
For fastening with vacuum, the surface must be smooth
and level. Application on plaster or brickwork is not
possible.

(see figure D and E)
With use of a Bosch quick-clamping column (acces-
sory), the drill stand can be fastened between 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 sufficient stability and be secure
against slipping.
For fastening of the quick-clamping column, read and
follow the respective operating instructions.
