The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

Assembly
Changing the Tool (see figure A)
 Before any work on the machine itself, pull the mains
plug.
Open the key type drill chuck 1 by turning until the tool can be
inserted. Insert the tool.
Insert the chuck key 6 into the corresponding holes of the key
type drill chuck 1 and clamp the tool uniformly.
Screwdriver Tools (see figure B)
When working with screwdriver bits 7, a universal bit holder 8
should always be used. Use only screwdriver bits that fit the
screw head.

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. 25–30 Nm.

Dust/Chip Extraction

 Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts 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.
Reversing the rotational direction
 Actuate the rotational direction switch 4 only when the
machine is at a standstill.
The rotational direction switch 4 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 3 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 4 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 4 through to the
right stop.
Switching On and Off
To start the machine, press the On/Off switch 3 and keep it
pressed.
To lock the pressed On/Off switch 3, press the lock-on button
2.
To save energy, only switch the power tool on when using it.
To switch off the machine, release the On/Off switch 3.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 3 is pressed.
