Mounting the Drill Chuck (see figure F)
The keyless chuck is mounted in reverse order.
Remove the steel pin from the drill hole on
the spindle neck after mounting is complet-
ed.
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. 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.
Operation
Starting Operation
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 G–H)
Actuate the rotational direction switch 3
only when the machine is at a standstill.
The rotational direction switch 3 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 5 actuated.

Right Rotation: For drilling and driving in
screws, push the rotational direction switch 3
upward on the left side and at the same time
downward on the right side.
Left Rotation: For loosening and unscrewing
screws and nuts, push the rotational direction
switch 3 downward on the left side and at the
same time upward on the right side.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 2 to the "Drill-
ing" symbol.
Impact Drilling
Set the selector switch 2 to the "Im-
pact drilling" symbol.
The selector switch 2 engages noticeably and
can also be actuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 5
and keep it pressed.
To lock the pressed On/Off switch 5, press the
lock-on button 4.
To switch off the machine, release the On/Off
switch 5 or when it is locked with the lock-on
button 4, briefly press the On/Off switch 5 and
then release it.
Adjusting the Speed/Impact Frequency
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 5 is pressed.
Light pressure on the On/Off switch 5 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Preselecting the Speed/Impact Frequency
With the thumbwheel for speed preselection 6,
the required speed/impact frequency can be
preselected even during operation.
The required speed/impact frequency depends
on the material and the working conditions, and
can be determined through practical testing.
