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
Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle (see figure A)
Operate your machine only with the auxiliary handle 8.
Before any work, make sure that the wing bolt 7 is firm-
ly tightened. Loss of control can cause personal injury.
The auxiliary handle 8 can be set to any position for a secure
and low-fatigue working posture.
Turn the wing bolt for adjustment of the auxiliary handle 7 in
anticlockwise direction and set the auxiliary handle 8 to the
required position. Then tighten the wing bolt 7 again in clock-
wise direction.
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the depth stop 9.
Press the button for the depth stop adjustment 6 and insert
the depth stop into the auxiliary handle 8.
The knurled surface of the depth stop 9 must face downward.
Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop correspond with the
desired drilling depth X.
Changing the Tool (see figure B)
Key Type Drill Chuck
Wear protective gloves when changing the tool. The
drill chuck can become very hot during longer work peri-
ods.
Open the key type drill chuck 1 by turning until the tool can be
inserted. Insert the tool.
Insert the chuck key 11 into the corresponding holes of the
key type drill chuck 1 and clamp the tool uniformly.
Screwdriver Tools
When working with screwdriver bits 13, a universal bit holder
12 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 power tools without spindle lock, the drill chuck
must be replaced by an authorised 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
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.
