Bosch Power Tools

Switching On and Off

To 

start

 the machine, press the On/Off switch 

10

 and keep it pressed.

To switch off the machine, 

release

 the On/Off 

switch 

10

.

Adjusting the Speed

The speed of the switched on power tool can be 
variably adjusted, depending on how far the 
On/Off switch 

10

 is pressed.

Light pressure on the On/Off switch 

10

 results 

in a low rotational speed. Further pressure on 
the switch results in an increase in speed.

Fully automatic spindle locking (Auto-lock)

When the On/Off switch 

10

 is not pressed, the 

drill spindle and thus the tool holder are locked.
This enables screws to be screwed in, even 
when the battery is empty and allows for the 
machine to be used as a screwdriver.

Run-on Brake

When the On/Off switch 

10

 is released, the 

chuck brakes to a stop, thus preventing the run-
on of the tool.
When driving in screws, wait until the screw is 
screwed in flush with the material and then re-
lease the On/Off switch 

10

. By doing so, the 

head of the screw does not penetrate into the 
material.

Working Advice

f

Apply the power tool to the screw only 
when it is switched off. 

Rotating tool inserts 

can slip off.

Note: 

Pay attention that no metal particles enter 

the power tool.
After longer periods of working at low speed, al-
low the machine to cool down by running it for 
approx. 3 minutes at maximum speed with no 
load.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS = high-speed steel). The 
appropriate quality is guaranteed 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. 

2

/

3

 of the screw length.

Maintenance and Service

Maintenance and Cleaning

f

Before any work on the machine (e. g., 
maintenance, tool change, etc.) as well as 
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. 

Unintentional actuation of the On/Off 

switch can lead to injuries.

f

For safe and proper working, always keep 
the machine and ventilation slots clean.

If the machine should fail despite the care taken 
in manufacturing and testing procedures, repair 
should be carried out by an after-sales service 
centre for Bosch power tools.
In all correspondence and spare parts order, 
please always include the 10-digit article 
number given on the type plate of the machine.

Replacing the Carbon Brushes (see figure H)

When the carbon brushes are worn, the power 
tool switches off automatically. For replacement 
of the carbon brushes, unscrew the four screws 
of the cover lid 

16

 and remove the cover lid 

16

. 

Insert a screwdriver or similar into the notch of 
the brush holder 

15

 and carefully pry it out. Re-

move the used carbon brushes and replace 
them. The new carbon brushes can also be in-
serted when turned by 180 ° . Lightly press the 
inserted carbon brushes downward until they 
can be clearly heard to engage. Afterwards 
mount the cover lid 

16

 again.
