Assembly
Mounting the Drill Stand
Supporting Angles
The supporting angles 12 can be mounted in
two positions:
– The basic position (see Fig. A) is necessary
when the GDB 2500 WE is installed into the
drill stand and the drill stand is not securely
mounted via anchor or quick-clamping
column.
– The space-saving position (see Fig. B) is only
possible when using the GDB 1600 WE/DE
or when the drill stand is securely fastened
to the wall. Assembly of the water collection
ring (accessory) for the GDB 2500 WE is not
possible in this position.
To switch between both positions, loosen the
knurled screws 13, adjust the supporting angles
12 to the required position and tighten them
again with the knurled screws.
Feed Handle
Press the lock pin 16 on the feed handle and
keep it pressed. Slide the feed handle 17 to the
stop left or right of the drill fixture 8 as required.
Release the lock pin 16 and check the feed han-
dle for tight seating.

handle 17 until the lock can be heard to engage.

lock 3 upward (A), turn it (B) and allow it to en-
gage in position .

Transport Wheels
For transport of the drill stand, screw the trans-
port wheels 15 to the sides of the drill stand
with the hexagon screws 14.
Fastening the Drill Stand
Note: Fasten the drill stand free from play to
prevent jamming of the core bit and the tearing
out of segments.
Depending on the type and surface quality, fas-
ten the drill stand with anchor or quick-clamp-
ing column at the planned drill hole.
Positioning the Drill Stand before Fastening
GDB 2500 WE
Fold out the drill-hole centre indicator 10. When
working with the GDB 2500 WE, bring the tip of
the drill-hole centre indicator into alignment

the inner edge of the drill-hole centre indicator
10 is the reference point.
