The drill chuck must be tightened with a
tightening torque of approx. 30–35 Nm.
Dust/Chip Extraction
f
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
f
Prevent dust accumulation at the work-
place.
Dusts can easily ignite.
Operation
Starting Operation
f
Observe correct mains voltage! The voltage
of the power 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)
f
Actuate the rotational direction switch 5
only when the machine is at a standstill.
The rotational direction switch

is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch

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
