Fitting the drill chuck
The fitting of the keyless chuck/keyless chuck with securing

The drill chuck must be tightened using a tight-
ening torque of approx. 50–55 Nm.
For keyless/keyed chucks
Screw the securing screw (16) anticlockwise into the open
keyless/keyed chuck.
Always use a new securing screw, as their thread is applied
with a securing adhesive substance, which is rendered inef-
fective after several uses.

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.
