Dust/Chip Extraction

Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

Operation

Starting Operation

Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (7) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (9) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure D)
The rotational direction switch (7) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (7) through to the left stop.
Left rotation: To loosen and unscrew screws, press the ro-
tational direction switch (7) through to the right stop.
Preselecting the Torque
The torque presetting ring (4) can be used to preselect the
required torque in 20 stages. When the correct setting is
used, the application tool will be stopped when the screw is
driven flush into the material or once the set torque has been
reached. In position the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, you can select a higher setting or
set the tool to the symbol.
Mechanical gear selection
Only operate the gear selector (6) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(6).
Gear I:
Low speed range; for screwdriving or working with a large
drilling diameter.
Gear II:
High speed range; for working with a small drilling diameter.
