Bosch Power Tools

Setting the operating mode

Drilling and Screwdriving

Set the selector switch 

2

 to the “Drilling” symbol.

Impact Drilling

Set the selector switch 

2

 to the “Impact drilling” 

symbol.

The selector switch 

2

 engages noticeably and can also be ac-

tuated with the machine running.

Gear selection, mechanical



The gear selector 7 can be actuated on machines run-
ning at low speed. However, this should not be done 
when the machine is stopped, at full load or running at 
maximum speed.

Two speed ranges can be preselected with the gear selector 

7

.

Gear I:

Low speed range; for working with large drill-
ing diameter or for driving in screws.

Gear II:

High speed range; for working with small 
drilling diameter.

If the gear selector 

7

 cannot be fully engaged, lightly rotate 

the drive spindle with the drill bit by twisting the drill chuck.

Switching On and Off

To 

start

 the machine, press the On/Off switch 

6

 and keep it 

pressed.

To lock the 

pressed

 On/Off switch 

6

, press the lock-on button 

4

.

To 

switch off

 the machine, release the On/Off switch 

6

 or 

when it is locked with the lock-on button 

4

, briefly press the 

On/Off switch 

6

 and then release it.

To save energy, only switch the power tool on when using it.

Safety Clutch

To limit high reaction torque, the power tool is equipped with 
a safety clutch (Anti-Rotation).



If the tool insert becomes caught or jammed, the drive 
to the drill spindle is interrupted. Because of the forces 
that occur, always hold the power tool firmly with both 
hands and provide for a secure stance.



If the power tool jams, switch the machine off and loosen 
the tool insert. When switching the machine on with the 
drilling tool jammed, high reaction torques can occur.

Adjusting the Speed/Impact Frequency

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

6

is pressed.

Light pressure on the On/Off switch 

6

 results in low speed/ 

impact rate. Further pressure on the switch increases the 
speed/impact rate.

Preselecting the Speed/Impact Frequency

With the thumbwheel for speed preselection 

5

, the required 

speed/impact frequency can be preselected even during op-
eration.

The required speed/impact frequency depends on the mate-
rial and the working conditions, and can be determined 
through practical testing.

Working Advice



Before any work on the machine itself, pull the mains 
plug.



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

Rotating tool inserts can slip off.

Tips

After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.

For drilling in tiles, set the selector switch 

2

 to the “Drilling” 

symbol. Do not switch over to the symbol “Impact Drilling” or 
work with impact until after drilling through the tile.

Use carbide tipped drill bits when working in concrete, ma-
sonry and brick wall.

For drilling in metal, use only perfectly sharpened HSS drill 
bits (HSS = high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.

Twist drills from 2.5 – 10 mm can easily be sharpened with 
the drill bit sharpener (see accessories).

Maintenance and Service

Maintenance and Cleaning



Before any work on the machine itself, pull the mains 
plug.



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

If the replacement of the supply cord is necessary, this has to 
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
