operation, and for use with a drill stand (here it is
possible to operate the drill with a water extraction

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.

must switch off, i.e. the red indicator light (1)
goes out.
•
Press the −ON− (RESET) button again (2).
The wet diamond drill must now be able to be
switched on.
•
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.
