Battery charge-control indicator
When the on/off switch (4) is pressed in halfway or com-
pletely, the battery charge-control indicator (6) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
LEDs
3× continuous green light
2× continuous green light
1× continuous green light
1× flashing green light
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Protection against deep discharge
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Angled Drill Head (see figure D)
The drill head can be locked in 5 different angle positions.
Push the release button (5) and swivel the tool head to the
required position. Then, let go of the release button (5)
again.
Before starting operation, check if the drill head is
u
locked in the respective angle position. This poses a
risk of injury.

Practical advice

Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
Before screwing larger, longer screws into hard materials, it
is advisable to pre-drill a pilot hole with the core diameter of
the thread to approx. 2/3 of the screw length.

Maintenance and Service

Maintenance and Cleaning

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.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.

Transport
The recommended lithium-ion batteries are subject to legis-
lation on the transport of dangerous goods. The user can
transport the batteries by road without further require-
ments.
When shipping by third parties (e.g.: by air transport or for-
warding agency), special requirements on packaging and la-
belling must be observed. For preparation of the item being
shipped, consulting an expert for hazardous material is re-
quired.
Dispatch battery packs only when the housing is undam-
aged. Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in the
packaging. Please also observe the possibility of more de-
tailed national regulations.
Disposal
Only for EU countries:
According to the Directive 2012/19/EU on waste electrical

the Directive 2006/66/EC, defective or drained batteries
Power tools, rechargeable batteries, accessor-
ies and packaging should be sorted for environ-
