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
10.
 Before any work, make sure that the wing bolt 11 is
firmly tightened. Loss of control can cause personal inju-
ry.
The auxiliary handle 10 can be set to any position for a secure
and low-fatigue working posture.
Turn the wing bolt for adjustment of the auxiliary handle 11 in
anticlockwise direction and set the auxiliary handle 10 to the
required position. Then tighten the wing bolt 11 again in
clockwise direction.
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the depth stop 1.
Press the button for the depth stop adjustment 5 and insert
the depth stop into the auxiliary handle 10.
The knurled surface of the depth stop 1 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 corresponds with the
desired drilling depth X.

Changing the Tool (see figure B)
Keyless Chuck
Hold the rear sleeve 3 of the keyless chuck 4 tight and turn the
front sleeve 2 in rotation direction , until the tool can be in-
serted. Insert the tool.
Hold the rear sleeve 3 of the keyless chuck 4 tight and firmly
turn the front sleeve 2 in rotation direction  by hand.
Screwdriver Tools
When working with screwdriver bits 14, 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 6 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.
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 (see figures C–D)
The rotational direction switch 8 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 9 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 8 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 8 through to the
right stop.
