Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 7 through to the right stop.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 3 to the "Drill-
ing" symbol.
Impact Drilling
Set the selector switch 3 to the "Impact
drilling" symbol.
The selector switch 3 engages noticeably and
can also be actuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 5
and keep it depressed.
To lock the pressed On/Off switch 5, press the
lock-on button 4.
To switch off the machine, release the On/Off
switch 5 or when it is locked with the lock-on but-
ton 4, briefly press the On/Off switch 5 and then
release it.
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 5 is pressed.
Light pressure on the On/Off switch 5 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 6,
the required speed/impact frequency can be
preselected even during operation.
The required speed/impact frequency depends
on the material and the working conditions, and
can be determined through practical testing.

Working Advice

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 machine to cool down by running it for approx.
3 minutes at maximum speed with no load.

For drilling in tiles, set the selector switch 3 to
the "Drilling" symbol. Do not switch over to the
symbol "Impact Drilling" or work with impact un-
til after drilling through the tile.
Use carbide tipped drill bits when working in
concrete, masonry and brick wall.
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.
Twist drills from 2,5–10 mm can easily be sharp-
ened with the drill bit sharpener (see accesso-
ries).
