Water Extraction
In order to collect the water coming out of the
bore during wet-drilling, a water collection ring
and a multi-purpose vacuum cleaner are re-
quired (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 observe its operating instructions.
Working Advice
For drilling, observe the operating instruc-
tions of your diamond drill.
For drilling, loosen the lock pin for the feed han-
dle 17 (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 H)
In order to achieve good drilling results, the play
between the drill fixture 8 and thr drilling col-
umn 2 must be as small as possible.
For readjustment, loosen the four Allen screws
27. Tighten the sliding elements 26 with slight
pressure toward the drilling column by turning
the two adjustment screws 28. Pay attention
that the drill fixture is aligned parallel to the
drilling column.
When the sliding behaviour is sufficient, lock the
adjustment screws 28 by retightening the Allen
screws 27.
