Description

The DD EC-1 is an electrically-powered diamond core
drilling machine for wet drilling.
Items supplied: The following items are supplied: elec-
tric tool, water collector holder including water collec-
tor, supply cord equipped with PRCD, operating instruc-
tions, lubricant spray (50 ml), cleaning cloth, toolbox.
The following conditions must always be observed
when the tool is in use:
– The tool must be connected to an alternating current
electric mains supply in compliance with the infor-
mation given on the type plate.
– The tool must not be used in places where the sur-
rounding conditions present a risk of explosion.
– The water collector with the correct sleeve must
always be used.

NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised
test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assess-
ment of exposure. The declared vibration emission level represents the main applications of the tool. However if
the tool is used for different applications, with different accessories or poorly maintained, the vibration emission
may differ. This may significantly increase the exposure level over the total working period. An estimation of the
level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working peri-
od. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organisation of work patterns.
