 Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 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.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against
continuous intense sunlight, fire, water, and
moisture. Danger of explosion.
 In case of damage and improper use of the battery, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
 Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
 The battery can be damaged by pointed objects such as
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.

Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-2.
Typically the A-weighted noise levels of the product are:
Sound pressure level 74 dB(A); sound power level 85 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-2:
Screwdriving without impact: a <2.5 m/s
h
The vibration 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 anoth-
er. It may be used for a preliminary assessment of exposure.
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 insertion tools or is
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 sig-
nificantly reduce the exposure level over the total working
period.
