Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Bosch Power Tools
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.
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
Do not operate your power tool without the auxiliary
u
handle (16).
Make sure that the auxiliary handle is always
u
tightened. Otherwise you could lose control of the power
tool when working.

Capacity
Selecting drill chucks and tools
60–100 %
For hammer drilling and chiselling, you will need SDS plus
30–60 %
tools, which insert into the SDS plus drill chuck.
5–30 %
For drilling without impact in wood, metal, ceramic and
0–5 %
plastic as well as for screwdriving, tools without SDS plus
are used (e.g. cylindrical shank drill bits). A keyed chuck is
required for such drilling tools.
Note: Only use the keyed chuck in the drilling without im-
pact operating mode.
Changing the drill chuck
Capacity
80–100 %
Inserting/removing the keyed chuck
60–80 % You must use a suitable drill chuck (keyed or keyless chuck,
accessories) to work with tools that do not have SDS-plus
40–60 %
(e.g. cylindrical shank drill bits).
20–40 %
Fitting the keyed chuck (see figure B)
5–20 %
– Screw the SDS-plus shank (20) into a keyed chuck (19).
Secure the keyed chuck (19) using the securing screw
