When wet drilling over-
head, the escaping water
must be collected. To do
this, insert the power tool in-
to a drill stand and mount a
water collecting ring (see
"Accessories/Spare Parts",
page 14).
 Ensure that water-carrying hoses, connectors and the
water collection ring (accessory) are in immaculate
condition. Replace damaged or worn parts before the
next use. Water escaping from parts of the power tool will
increase the risk of electric shock.
Product Description and Specifications
Read all safety warnings and all instruc-
tions. Failure to follow the warnings and in-
structions may result in electric shock, fire
and/or serious injury.
While reading the operating instructions, unfold the graphics
page for the machine and leave it open.
Intended Use
In conjunction with diamond wet-drilling core bits and a water
supply, the power tool is intended for wet drilling in mineral
materials such as concrete, reinforced concrete or brickwork.
The power tool can be combined with an extraction device
(water collection ring and wet/dry vacuum cleaner).
The power tool must only be used together with the diamond
drill stand GCR 350.
Using an anchor, the drill stand for diamond drills can be fas-
tened to the floor, wall and overhead.
The drill stand for diamond drills can be attached to the floor
by means of vacuum (accessory) or (with an additional safe-
guard) against the wall. Attaching overhead is not permitted.
The drill stand for diamond drills can be attached to the floor
using the quick-clamping column. Attaching to a wall or over-
head is not permitted.

The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
Noise Information
Sound emission values determined according to
EN 61029-2-6.
Typically the A-weighted noise levels of the product are:
Sound pressure level 96 dB(A); Sound power level
110 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 61029 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 in-
crease 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 sig-
nificantly reduce the exposure level over the total working pe-
riod.
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 pat-
terns.
