3.5 Intended use
Wet diamond drill
The BDB 819 wet diamond drill is designed for both
hand-held operation, and for use with a drill stand
(here it is possible to operate the drill with a water
extraction kit).
NOTE
The wet diamond drill is not suitable for overhead
drilling.
For hand-held drilling, the centring suction plate
and a suitable water suction appliance (e.g. BAIER
special dust extractor) is to be used.
The wet diamond drill, in conjunction with wet
diamond core drill bits and a water supply, is
intended for wet drilling into mineral materials such
as concrete, reinforced concrete or masonry. Never
work without water extraction.
The following materials may not be drilled: wood,
metal and glass, etc.
Observe the relevant regulations in your
country for the materials to be machined and
extraction.
4 Before Starting Work
To ensure safe working with the wet diamond drill,
the following points must be observed before each
use:
•
Read through all safety instructions and
warnings in this instruction manual.
•
Wear protective clothing such as hard hat, face
protection or safety goggles, safety gloves,
suitable half-face filter mask, slip-resistant
safety footwear and if necessary an apron.
•
The voltage on the rating plate must be identical
with the mains voltage.
•
Before each use, check the machine, connection
cable, plug, secure fit of the wet diamond core
drill bit and, if applicable, the fixing of the drill
stand.
•
Always note and follow the thread dimension of
the wet diamond drill bit holder. The thread of
the wet diamond core drill bits must fit on the
thread of the wet diamond drill (G½” internal
thread or 1¼” UNC external thread) without any
clearance. Do not use reducers or adaptors to fit
the wet diamond core drill bits.
•
Check the condition of the wet diamond drill bit
with a visual inspection.
NOTE
Damaged wet diamond core drill bits may not be
used and must be replaced immediately.
•
Only use diamond core drill bits recommended
by OTTO BAIER GmbH for the respective area
of use.
NOTE
The wet diamond core drill bit can become
irreparably damaged by overheating or jamming in
the drill core hole (see “Handling wet diamond core
drill bits” on page 48).
If harmful dust is produced during the work, a
suitable dust extractor must be connected to the
wet diamond drill
(e.g. BAIER special dust extractor).
•
Connect a suitable water extractor.
•
The additional handle must be tightly screwed
onto the drill for hand-held drilling.
