Safety class
• 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 combination, 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 EN60745:
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 ) : 98 dB (A)
WA
Uncertainty (K) : 3 dB(A)
WARNING:
Wear ear protection.
Vibration

Vibration emission (a
Uncertainty (K) : 1.5 m/s
Work mode: drilling into metal
Vibration emission (a
Uncertainty (K) : 1.5 m/s
NOTE: The declared vibration emission value has
been measured in accordance with the standard test
method and may be used for comparing one tool with
another.
NOTE: The declared vibration emission value
may also be used in a preliminary assessment of
exposure.
WARNING:
The vibration emission during actual
use of the power tool can differ from the declared
emission value depending on the ways in which the
tool is used.
WARNING:
Be sure to identify safety measures
to protect the operator that are based on an estima-
tion 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).
