Protection class
The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
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.
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
clockwise direction.
Adjusting the Drilling Depth
The required drilling depth X can be set with the depth stop 9.
– Loosen the wing bolt for the depth stop adjustment 6 and
insert the depth stop rod into the auxiliary handle 8.
The knurled surface of the depth stop 9 must face upward.
– 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.
– Retighten the wing bolt for the depth stop adjustment 6
again.
Changing the Tool
 Wear protective gloves when changing the tool. The
drill chuck can become very hot during longer work peri-
ods.
Key Type Drill Chuck (see figure B)
– 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.

Dust/Chip Extraction

mm 13
 Dust from materials such as lead-containing coatings,
mm 10
some wood types, minerals and metal can be harmful to
mm 25
one's health. Touching or breathing-in the dust can cause
mm 1.5 – 13
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
kg 1.8
Certain dust, such as oak or beech dust, is considered car-
/II
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.
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.
Setting the operating mode
The drill chuck must be tightened with a tightening
torque of approx. 30–35 Nm.
Drilling and Screwdriving
Set the selector switch 2 to the "Drilling" symbol.
