Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Reversing the rotational direction
The rotational direction switch 7 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 6 actuated.
Right rotation: Press the rotational direction switch 7
through to the right stop (for drilling and driving screws).
Left rotation: Press the rotational direction switch 7 through
to the left stop (for loosening and unscrewing screws and
nuts).
Gear selection, mechanical
The gear selector 8 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
Two speed ranges can be preselected with the gear selector
8.
Gear I:
Low speed range; for working with large drilling diameter or
for driving in screws.
Gear II:
High speed range; for working with small drilling diameter.
If the gear selector 8 cannot be fully engaged, lightly rotate
the drive spindle with the drill bit by twisting the drill chuck.
Preselecting the Speed
The required speed can be preselected with the thumbwheel
5 (also while running).
The required speed depends on the material to be worked
and the diameter of the tool. Determine the optimum setting
through practical testing.
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.
Overload Clutch
To limit high reaction torque, the power tool is equipped with
an overload 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 loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.

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 rotation-
al speed. Further pressure on the switch results in an increase
in speed.
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.
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).
We recommend the use of a drill stand (see accessories) for
work where greater precision is particularly required.
The machine vice, which is available as an accessory, enables
secure clamping of workpieces. This prevents the workpiece
from turning and any accidents this would cause.
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.
