6.8 Water collection system for use with the drill stand
Use of the water collection system permits water to be
drained away from the core bit thus avoiding soiling the
surrounding area. Best results are achieved in conjunc-
tion with a wet-type vacuum cleaner.
Use of the water collection system in conjunction with
a wet-type vacuum cleaner is mandatory for overhead
drilling. The drill stand must be set up at 90° to the work
surface.
The water collector sleeve and seal must be of a size
suitable for the core bit diameter used.
1. Slacken the column adjusting lever until the locating
lugs are disengaged.
2. Tilt the frame.
3. Fit the water collector holder.
4. Bring the frame back to the vertical position.
5. Close the adjusting levers until the locating lugs are
fully engaged and the frame is again secured.
6. Lift the holder and push the water collector cup under
the retainer as far as it will go.
7. Connect a wet-type vacuum cleaner to the water col-
lector cup or connect a length of hose through which
the water can flow away.
