Intended use
The tool is intended for hammer drilling and drilling in
brick, concrete and stone as well as for chiselling work.
It is also suitable for drilling without impact in wood,
metal, ceramic and plastic.
Noise
The typical A-weighted noise level determined accord-
ing to EN60745:
Sound pressure level (L
Sound power level (L
Uncertainty (K) : 3 dB (A)
Wear ear protection
Vibration
The vibration total value (tri-axial vector sum) deter-
mined according to EN60745:
Work mode : hammer drilling into concrete
Vibration emission (a
Uncertainty (K) : 1.5 m/s
Work mode : chiselling
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).

General Power Tool Safety Warnings

WARNING Read all safety warnings and all instruc-
tions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions for
future reference.
CORDLESS ROTARY HAMMER
SAFETY WARNINGS
1. Wear ear protectors. Exposure to noise can
cause hearing loss.
2. Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
3. Hold power tool by insulated gripping sur-
faces, when performing an operation where the
cutting accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
4. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
Be sure the bit is secured in place before operation.
5.
6. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for
a while by operating it under no load. This
will loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
