Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Bosch Power Tools
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Auxiliary handle

to
Do not operate your power tool without the auxiliary
u
handle (13).
Make sure that the auxiliary handle is always
u
tightened. Otherwise you could lose control of the power
tool when working.
Swivelling the auxiliary handle (see figure A)
You can swivel the auxiliary handle (13) to any angle for a
safe work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (13)
anticlockwise and swivel the auxiliary handle (13) into
the required position. Then turn the lower gripping end of

The dust protection cap (3) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (3)
does not become damaged.

– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus application
tool can move freely. This causes a certain radial run-out at
no-load, which has no effect on the accuracy of the drill hole,
as the drill bit centres itself upon drilling.
Removing SDS-plus application tools (see figure B2)
– Push the locking sleeve (4) back and remove the applica-
tion tool.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
