 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.
 Use only original Bosch batteries with the voltage list-
ed on the nameplate of your power tool. When using oth-
er 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
Sound emission values determined according to
EN 60745-2-1. Typically the A-weighted noise levels of the product are:
Sound pressure level 87 dB(A); Sound power level 98 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
Drilling into metal: a <2.5 m/s , K =1.5 m/s
h
Impact drilling into concrete: a =17 m/s
h
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.
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 pat-
terns.
