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 warn-
ings in this instruction manual.
•
Wear protective clothing such as hard hat, face
protection or safety goggles, safety gloves, suit-
able 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, connec-
tion cable, plug, secure fit of the wet diamond
core drill bit and, if applicable, the fixing of the
drill stand.
• Connect a suitable water supply (e.g. BAIER wa-
ter pressure vessel, see "Tools and Accesso-
ries" on page 43 or BAIER catalogue) to the
BDB 802B (see page 39).
•
Inform and consult the responsible structur-
al engineer, architect or the responsible site en-
gineer about planned drilling. Cut through rein-
forcement only with the approval of a structural
engineer.

DANGER
Risk of injury due to electric shock.
Î The personal protection switch PRCD must be
checked each time before the wet diamond dill
is started up (see below). If the PRCD does not
trip during the test or if it repeatedly switches
off when the wet diamond drill is switched on,
the wet diamond drill together with the PRCD
personal protection switch must be examined
by a qualified electrician.
•

diamond drill switched off, press the −ON− (RE-
