Levelling (does not apply for fastening with
vacuum)
Screw the levelling screws 13 in or out individually, until
the spirit level 4 (for vertical assembly) or the spirit level
5 (for horizontal assembly) is precisely aligned.
Now, firmly fasten the drill stand with anchor attach-
ment or with the quick-clamping column.
Operation
After each adjustment on the drill stand,
firmly retighten all screws and locking han-
dles and allow the locks to engage again.
Drilling-angle Adjustment (see figure F)
Loosen the upper 23 and the lower locking handle 20
for drill-angle adjustment.
Pull the lock button for drill-angle adjustment 22. Adjust
the drill stand to one of the four possible drilling angles
(0°, 15°, 30° or 45°) and allow the lock button to engage
into the corresponding hole in the drilling column.
Tighten both locking handles 23 and 20 again.
The drill stand may not be used until both
locking handles of the angle adjustment have
been tightened again.
Mounting the Diamond Drill
(see figure G)
Loosen the locking handles 6 and 7 on the drill stand.
Pay attention that the feed handle 18 is blocked by the
feed lock 3 (see "Feed Handle").
Insert the power tool from above into the drill fixture 8
down to the stop. Retighten the locking handles 6 and
7 again. When mounting the GDB 1600 WE/DE, the
upper locking handle 6 is not required.
Place the water hose and the mains cable of the power
tool into the holders of the drill fixture on the drill stand.
Proceed in reverse order when removing the power
tool from the drill stand.
Adjusting the Drilling Depth
(see figure H)
With the depth stop 11, the drilling depth t can be deter-
mined.
Mount the core bit to the drill. With the feed handle, lower
the switched off drill so far until the core bit faces against
the wall. In this position, the set drilling depth t corre-
sponds with the distance between the lower edge of the
drill fixture 8 and the upper edge of the depth stop 11.
Loosen the locking handle 10 at the depth stop and
adjust the required drilling depth. Firmly tighten the lock-
ing handle again.

Water Extraction
In order to collect the water coming out of the bore dur-
ing wet-drilling, a water collection ring and a multi-pur-
pose vacuum cleaner are required (both accessories).
The choice of the water collection ring depends on the
diamond drill (GDB 2500 WE or GDB 1600 WE/DE)
being used.
For assembly of the water collection ring, read and fol-
low its operating instructions.
Operating Instructions
For drilling, observe the operating instruc-
tions of your diamond drill.
For drilling, loosen the lock pin for the feed handle 18
(see "Feed Handle").
Lower the drill to the required drilling depth by turning
the feed handle.
Then, turn the crank back until the core bit is completely
visible.

Maintenance and Service

Maintenance and Cleaning

Always keep the rack 9 and the guide surfaces of the
der drilling column 2 clean.
Readjusting the Drill Fixture (see figure I)
In order to achieve good drilling results, the play
between the drill fixture 8 and thr drilling column 2 must
be as small as possible.
For readjustment, loosen the four Allen screws 28.
Tighten the sliding elements 27 with slight pressure
toward the drilling column by turning the two adjust-
ment screws 29. Pay attention that the drill fixture is
aligned parallel to the drilling column.
When the sliding behaviour is sufficient, lock the
adjustment screws 29 by retightening the Allen screws
28.
If the drill stand should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an authorised after-sales service cen-
tre for Bosch power tools.
In all correspondence and spare parts orders, please
always include the 10-digit article number given on the
nameplate of the drill stand.
