Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
Operation

Starting Operation

Inserting the battery
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Insert the charged battery 4 from the front into the base of the
power tool until the battery is securely locked.
Reversing the rotational direction (see figure G)
(see figure H)
The rotational direction switch 5 is used to reverse the rotati-
onal direction of the machine. However, this is not possible
with the On/Off switch 6 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 5 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 5 through to the
right stop.
Setting the torque (see figure I)
With the torque presetting ring 2 the required torque setting
can be preselected in 18 steps. With the correct setting, the
insert tool is stopped as soon as the screw is screwed flush in-
to the material or when the adjusted torque is reached. The
safety clutch is deactivated in the
ling.
Select a higher setting or switch to the
screwing screws.
Gear selection, mechanical
 Actuate the gear selector 3 only when the machine is at
a standstill.
Two speed ranges can be preselected with the gear selector
3.
Gear 1:
Low speed range; for screwdriving or for working with a large
drilling diameter.
Gear 2:
High speed range; for working with a small drilling diameter.
 Always push the gear selector through to the stop.
Otherwise, the machine can become damaged.
Switching On and Off
To start the machine, press the On/Off switch 6 and keep it
pressed.

The work light 9 illuminates when the On/Off switch 6 is lightly
or fully pressed and allows the illumination of the work area in
poor lighting conditions.
The worklight 9 will remain lit for approx. 10 seconds when
the On/Off switch 6 has been released.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 6 is pressed.
Light pressure on the On/Off switch 6 results in a low rotatio-
nal speed. Further pressure on the switch results in an incre-
ase in speed.
Fully automatic spindle locking (Auto-lock)
The drill spindle and therefore the mounting are locked when
the On/Off switch 6 is not pressed.
This enables screws to be screwed in, even when the battery
is empty and allows for the machine to be used as a screwdri-
ver.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be overloa-
ded. If the power tool is overloaded or not kept within the per-
mitted operating temperature range, the power output is re-
duced or the power tool is switched off. The power tool will
not run at full power output again until the permitted opera-
ting temperature has been reached.
Battery Charge-control Indication
The battery charge-control indicator 8 consists of three green
LEDs, and indicates the charge condition of the battery for a
few seconds when the On/Off switch 6 is pressed halfway or
fully.

Working Advice

 Apply the power tool to the screw only when it is swit-
ched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow the machi-
ne to cool down by running it for approx. 3 minutes at maxi-
mum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is gua-
ranteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is
advisable to predrill a pilot hole with the core diameter of the
thread to approx.
