Intended uses

The tool is intended for the following uses:
– Drilling holes (diamond core drilling) of 8–35 mm
diameter in reinforced concrete, masonry and natur-
al stone
– To be used exclusively for wet drilling and in con-
junction with the water collector and corresponding
water collector sleeves
– The tool must be connected to a mains supply pro-
viding a voltage and frequency in compliance with the
information given on the type plate.
– The tool may be used only when connected to a mains
supply equipped with an earth / ground conductor
and of adequate power rating.
– The tool may be used only with a mains supply cord
of the type intended for use with it, equipped with a
keyed socket connector and built-in PRCD (isolating
transformer for GB).
– In accordance with national safety regulations, the
safety function of the earth / ground conductor must
be tested at regular intervals.
– Before use, the PRCD must be tested for correct func-
tionality (see "Operation").
– Only the core bits and accessories designed for use
with this tool may be used.
The tool may be handled only as described in these oper-
ating instructions (care, maintenance, assembly, use,
etc.). Manipulation of the tool in ways other than as

The position and dimensions of the holes drilled must
be approved by the design engineer, architect or person
in charge of the building project (building statics).
Do not, under any circumstances, use this product in
any way other than as described in these operating
instructions.

Insert tools and accessories

For safety reasons and for optimum transmission of the
TOPSPIN action, only DD-C core bits may be used with
the DD EC-1. When drilling using special core bits with
a working length of 600 mm, the hole must be pre-drilled
using a shorter core bit and water collector.
The following accessories are available for use with the
DD EC-1:
– DD-REC 1 water recycling unit
– DD-CB core removal tool
– Vacuum cleaner adaptor
– Drill stand DD-CR1
