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 by-
standers.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in
connection with wood-treatment additives (chromate, wood preservative).Mate-
rials 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 materials to be worked.
 Prevent dust accumulation at the workplace. Dust can easily ignite.

Starting Operation
Reversing the rotational direction (see figure C)
The rotational direction switch 2 is used to reverse the rotational direction of the ma-
chine. 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 2 left to the stop.
Left Rotation: For loosening and unscrewing screws and nuts, press the rotational di-
rection switch 2 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it pressed.
The power light 6 lights up when the On/Off switch 4 is slightly or completely pressed,
and allows the work area to be illuminated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 4.
To save energy, only switch the power tool on when using it.
