Assembly

Battery Charging (see figure A)

Note: 

The battery supplied is partially charged. To ensure full 

capacity of the battery, completely charge the battery in the 
battery charger before using your power tool for the first time.

The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure 
does not damage the battery.

The lithium-ion battery is protected against deep discharging 
by the “Electronic Cell Protection (ECP)”. When the battery is 
empty, the machine is switched off by means of a protective 
circuit: The inserted tool no longer rotates.



Do not continue to press the On/Off switch after the 
machine has been automatically switched off. 

The bat-

tery can be damaged.

To remove the battery 

5

 press the unlocking buttons 

4

 and 

pull out the battery downwards. 

Do not exert any force.

Observe the notes for disposal.

Changing the Tool (see figure B)



Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport 
and storage, remove the battery from the power tool. 

There is danger of injury when unintentionally actuating 
the On/Off switch.

The drill spindle is locked when the On/Off switch 

7

 is not 

pressed. This makes quick, convenient and easy changing of 
the tool in the drill chuck possible.

Open the keyless chuck 

1

 by turning in rotation direction 



, 

until the tool can be inserted. Insert the tool.

Firmly tighten the collar of the keyless chuck 

1

 by hand in ro-

tation direction 



Dust/Chip Extraction



Dust from materials such as lead-containing coatings, 
some wood types, minerals and metal can be harmful to 
one’s health. Touching or breathing-in the dust can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.

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



Use only original Bosch lithium-ion batteries with the 
voltage listed on the nameplate of your power tool. 

Using other batteries can lead to injuries and pose a fire 
hazard.

Note: 

Use of batteries not suitable for the machine can lead to 

malfunctions of or cause damage to the power tool.

Set the rotational direction switch 

6

 to the centre position in 

order to avoid unintentional starting. Insert the charged bat-
tery 

5

 into the handle so that it can be felt to engage and faces 

flush against the handle.

Reversing the rotational direction (see figure C)

The rotational direction switch 

6

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

7

 actuated.

Right Rotation:

 For drilling and driving in screws, push the 

rotational direction switch 

6

 left to the stop.

Left Rotation:

 For loosening and unscrewing screws and 

nuts, press the rotational direction switch 

6

 through to the 

right stop.

Setting the torque

With the torque presetting ring 

2

 the required torque setting 

can be preselected in 20 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 “

” position, e. g. for 

drilling.
Select a higher setting or switch to the “

” symbol when un-

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 I:

Low speed range; for screwdriving or working with large drill-
ing diameter.

Gear II:

High speed range; for working with small drilling diameter.
