Insert the chuck key 11 into the corresponding holes of the
key type drill chuck 1 and clamp the tool uniformly.
Screwdriver Tools (see figure C)
When working with screwdriver bits 12, a universal bit holder
13 should always be used. Use only screwdriver bits that fit
the screw head.
For driving screws, always position the "Drilling/Impact Drill-
ing" selector switch 2 to the "Drilling" symbol.
Replacing the Drill Chuck
For machines without spindle lock, the drill chuck must be re-
placed through an authorized after-sales service agent for
Bosch power tools.
The drill chuck must be tightened with a tightening
torque of approx. 30–35 Nm.

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
 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.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
Reversing the rotational direction (see figures D–E)
 Actuate the rotational direction switch 5 only when the
machine is at a standstill.
The rotational direction switch 5 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 4 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 5 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 5 through to the
right stop.
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.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it
pressed.
To lock the pressed On/Off switch 4, press the lock-on button
3.
To switch off the machine, release the On/Off switch 4 or
when it is locked with the lock-on button 3, briefly press the
On/Off switch 4 and then release it.
To save energy, only switch the power tool on when using it.
Adjusting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 4
is pressed.
Light pressure on the On/Off switch 4 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Working Advice
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
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.
