performing an operation where the cutting accessory
or fastener may contact hidden wiring. Cutting
accessory and fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
u Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility
company for assistance. Contact with electric lines can
lead to fire and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line causes
property damage or may cause an electric shock.
u Switch off the power tool immediately when the tool
insert jams. Be prepared for high reaction torque that
can cause kickback. The tool insert jams when:
— the power tool is subject to overload or
— it becomes wedged in the workpiece.
u Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
u Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than by
hand.
u Keep your workplace clean. Blends of materials are
particularly dangerous. Dust from light alloys can burn
or explode.
u Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
u Do not open the battery. Danger of shortcircuiting.
Protect the battery against heat, e. g.,
also against continuous sun irradiation and
fire. There is danger of explosion.
u In case of damage and improper use of the battery,
vapours may be emitted. Provide for fresh air and
seek medical help in case of complaints. The vapours
can irritate the respiratory system.
u When the battery is defective, liquid can escape and
come into contact with adjacent components. Check
any parts concerned. Clean such parts or replace them,
if required.
u Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
u Use only original Bosch batteries with the voltage
listed on the nameplate of your power tool. When
using other batteries, e. g. imitations, reconditioned
batteries or other brands, there is danger of injury as
well as property damage through exploding batteries.

Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted sound pressure level of the product is
71 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).
Wear hearing protection!
Vibration total values (triax vector sum) determined according
to EN 60745:
Drilling into metal: Vibration emission value a
Uncertainty K =1.5 m/s ,
2
Screwdriving: Vibration emission value a
Uncertainty K =1.5 m/s .
2
The vibration emission level given in this information sheet has
been measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main
applications 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 increase 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 significantly
reduce the exposure level over the total working period.
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
patterns.
