• Due to our continuing program of research and development, the specifications herein are subject to change
without notice.
• Specifications may differ from country to country.
• The weight may differ depending on the attachment(s). The lightest and heaviest combinations, according to
EPTA-Procedure 01/2014, are shown in the table.

Intended use

The tool is intended for hammer drilling and drilling in
brick, concrete and stone.
It is also suitable for drilling without impact in wood,
metal, ceramic and plastic.

Power supply

The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and
can only be operated on single-phase AC supply. They
are double-insulated and can, therefore, also be used
from sockets without earth wire.
Noise
The typical A-weighted noise level determined accord-
ing to EN62841-2-6:
Model HR1840
Sound pressure level (L
Sound power level (L ) : 98 dB (A)
WA
Uncertainty (K) : 3 dB (A)
Model HR1841F
Sound pressure level (L
Sound power level (L ) : 96 dB (A)
WA
Uncertainty (K) : 3 dB(A)
NOTE: The declared noise emission value(s) has
been measured in accordance with a standard test
method and may be used for comparing one tool with
another.
NOTE: The declared noise emission value(s)
may also be used in a preliminary assessment of
exposure.

use of the power tool can differ from the declared
value(s) depending on the ways in which the
tool is used especially what kind of workpiece is
processed.
WARNING:
Be sure to identify safety mea-
sures to protect the operator that are based on an
estimation of exposure in the actual conditions of
use (taking account of all parts of the operating
cycle such as the times when the tool is switched
off and when it is running idle in addition to the
trigger time).
